Construction Finance Resources for Contractors

A civil contractor we work with had DSO sitting at 73 days when we started the engagement. He'd been running the business for 22 years and assumed that's just what construction looked like.

It wasn't. It was costing him roughly $1.7 million of working capital.

Six months later, his DSO was 41 days. Revenue was flat. Margins were flat. He'd done nothing operationally different in the field. The only change was how aggressively the office collected what the business had already earned.

That's a $1.7 million cash injection. No new sales, no margin expansion, no debt. Just collecting faster on work he'd already done.

Most $10M-$70M construction owners are sitting on the same opportunity and don't see it. Let's dive in.

What DSO is, and why construction DSO looks the way it does

Days Sales Outstanding is the average number of days it takes to collect a dollar of revenue after the invoice goes out. The formula is:

DSO = (Accounts Receivable / Total Revenue) × Number of Days

For most industries, healthy DSO is 30-45 days. Construction routinely runs 50-90+ days, and most owners accept that as normal.

It's normal in the sense that it's common. It is absolutely not necessary. Construction DSO is structurally higher than other industries because of three things:

1. Monthly progress billing. Most other industries invoice when goods ship or services complete. Construction invoices on a monthly cycle, which builds in 15-30 days of average lag before the invoice even goes out.
2. Progress billing review and approval cycles. A $300K progress invoice goes through a PM review, an owner's rep review, sometimes an architect's review, sometimes a lender's review. That's another 15-30 days.
3. Retainage. 5%-10% of every billing gets held back until project completion, often months after the work was done. We covered the retainage piece in our retainage post.

So construction DSO will never get down to a SaaS company's 30 days. But the difference between a well-runconstruction business at 40-55 DSO and a normal-run construction business at 70-90 DSO is millions of dollars in working capital on any contractor over $10M.

The cost of a high DSO, in dollar terms

For a $20M contractor:

• DSO of 90 days = A/R of $4.9M tied up at any given moment
• DSO of 60 days = A/R of $3.3M tied up
• DSO of 45 days = A/R of $2.5M tied up

Difference between 90-day DSO and 45-day DSO on a $20M business: $2.4 million of working capital. Cash. Yours, sitting in someone else's bank account.

At an 8% line of credit cost, that's $192K per year in interest expense if you're funding it with debt. At 10% margin, that's the equivalent of $1.92M of additional revenue you'd need to generate to make the same money.

This is why DSO is one of the four highest-leverage numbers in your business and why a CFO who isn't paying attention to it isn't actually doing the job.

The five places construction DSO actually breaks

We've worked DSO improvement on hundreds of contractor engagements. The same five issues account for almost all of the avoidable DSO. Fix these, and 20-30 days come off DSO in 90 days. Fix only some, and you'll get partial credit.

1. The invoice goes out late

The job did $480K of work in March. The invoice goes out on April 12th. Net 30 means it gets paid May 12th. Total cycle from work-performed to cash-collected: 42 days.

If the invoice had gone out on April 1st, total cycle: 30 days. You've just lost 12 days of DSO on every single billing because somebody on the team didn't have a hard April 1st deadline.

Most contractors at $10M-$70M have their monthly billing cycle drift by 7-14 days because nobody owns the invoice cutover date. Fix the date, set the deadline, every PM has draft billings to accounting by the 25th, invoices out the 1st. That's the easiest 7-14 days of DSO improvement most businesses have.

2. The invoice has paperwork problems

The customer requires AIA-format pay applications with notarized lien waivers. The invoice goes out with the wrong form, missing the waivers, or with math that doesn't tie. The customer kicks it back. The PM has to fix it. The cycle restarts.

This adds 15-30 days per occurrence. On a $20M business with 50 active invoices per month, even a 10% kick-back rate is 5 invoices a month spending an extra 20 days on average to collect. Math out at $20K-$30K of working capital cost per month.

The fix: a closeout checklist on every billing, plus a quick reconciliation between the PM and accounting before the invoice goes out. Twenty minutes per billing. Saves weeks.

3. Nobody is chasing receivables

The invoice went out. It's now 45 days overdue. Nobody has called the customer. The reason is usually a combination of three things: the owner doesn't want to bother the customer ("they're a good customer"), accounting isn't empowered to call, and nobody is looking at the A/R aging weekly.

This is the second-biggest source of preventable DSO. Just calling the customer at day 7 past due, day 21 past due, and day 35 past due collects faster, every single time, on every single invoice, with rare exception.

4. The aging report isn't reviewed at the owner level

The accounting team sees a customer drifting from 60 to 75 days. The PM doesn't see it. The owner doesn't see it. The customer keeps drifting because nothing in your business is escalating to the level where the owner picks up the phone.

Most contractors review the A/R aging quarterly or monthly. We review it on the Monthly Sales and Operations Update Call with every Civil CFO client. Different cadence, different conversation, different result.

5. The customer has structural payment delays you haven't priced in

Some customers (large national GCs, certain public agencies, certain developers) have structural payment cycles of 60-90 days regardless of what you do. That's a contract pricing decision, not an operations decision.

If you have a customer who consistently pays in 75 days and your pricing assumes 30, you're financing them at 45 days of interest cost per dollar of revenue. Either price that in or stop working for them. Pretending it's a collection problem won't fix it.

The 90-day DSO reduction plan

This is the playbook we run with new Civil CFO clients when DSO is a priority. None of it is complicated. Most contractors just haven't put it in one place.

Days 1-30: Set up the visibility

• A/R aging on the agenda for every Monthly Sales and Operations Update Call
• Aging segmented by customer, by job, and by aging bucket (current, 1-30, 31-60, 61-90, 90+)
• Retainage receivable broken out separately
• Top 10 aged invoices listed by dollar value with names and phone numbers
• A weekly 15-minute call between owner or controller and the person doing the actual chasing

Days 31-60: Tighten the front end

• Set a hard monthly invoice cutover date (1st of every month is standard)
• All PMs deliver draft billings to accounting by the 25th of the prior month
• Closeout checklist for every billing (forms correct, lien waivers attached, math tied)
• 15-minute PM/accounting reconciliation before invoice sends

Days 61-90: Tighten the back end

• Day 7 past due: automated email reminder
• Day 21 past due: phone call from accounting
• Day 35 past due: phone call from PM or controller
• Day 60 past due: phone call from owner, document the conversation
• Day 90 past due: escalation, potential lien filing depending on state and customer

If you run this sequence consistently, the customers who can pay on time will pay on time. The customers who can't will surface fast, which lets you make the decision on whether to keep working with them.

What DSO improvement is actually worth

For the $20M civil contractor we mentioned at the start:

• Starting DSO: 73 days, A/R of $4.0M
• 90-day target DSO: 50 days, A/R of $2.7M
• Cash released into the business: $1.3M

That $1.3M is enough to fund 8-10 weeks of payroll. It's enough to take down the line of credit by 40%. It's enough to buy a $400K piece of equipment with cash. It's enough to fund the next bid season without sweating Friday.

And it doesn't require new sales, margin improvement, or debt. It's collecting what you've already earned, faster.

For comparison, generating the same $1.3M of cash through new revenue at a 10% net margin requires $13M of additional revenue. Improving DSO is the highest-ROI cash project in most construction businesses.

DSO and the 13-Week Cash Flow Forecast

Every Civil CFO client has a rolling 13-Week Cash Flow Forecast updated monthly. The accounts receivable side of that forecast depends entirely on DSO assumptions.

When DSO comes down by 20 days, the forecast tightens by hundreds of thousands of dollars over the rolling 13 weeks. The forecast goes from "we'll probably be fine" to "here's exactly where we'll be." That's the difference between running the business and hoping.

Most contractors at $10M-$70M don't even know what their DSO is in any given month. The CFO seat fixes that first, then fixes the underlying mechanics, then watches the forecast tighten week by week.

What we do with DSO at Civil CFO

DSO management is a standard part of every Civil CFO engagement. In the first 90 days, we typically:

1. Calculate current DSO and benchmark it against your industry segment
2. Pull the A/R aging and identify the top 10 aged invoices by dollar value
3. Diagnose which of the five failure modes are dragging your DSO
4. Build the invoice cutover discipline with your accounting team
5. Install the receivables management cadence
6. Add A/R aging to the monthly cadence

We install the receivables management cadence and add A/R aging to the monthly cadence…

Nope. We do not make collections calls. That's the work of your accounting team or controller. Our job is to design the system, hold the line on the standards, and translate DSO movement into cash forecast clarity.

Most clients see 10-15 days of DSO improvement in the first 90 days and 20-30 days in the first year. That's $500K-$2M of working capital released into the business, depending on revenue size.

FAQ

What is DSO in construction?

Days Sales Outstanding is the average number of days it takes to collect revenue after invoicing. For construction, it's calculated as (Accounts Receivable / Total Revenue) × 365 (or 90 or 30 days, depending on the period). Healthy construction DSO is 40-55 days; many contractors run 70-90 days unnecessarily.

What's a good DSO for a construction company?

40-55 days is achievable and healthy for most $10M-$70M contractors. Anything over 60 days usually has 10-20 days of avoidable lag that can be removed with disciplined billing and collections. Below 40 days is rare and usually only seen in trades with shorter billing cycles.

How do I reduce my construction DSO?

Five levers: bill on a hard monthly cutover date, eliminate paperwork rework on invoices, chase receivables on a documented cadence, review the A/R aging weekly or at minimum monthly at the owner level, and stop working for customers who structurally pay late unless you've priced it in.

Does retainage affect DSO calculation?

Yes. Some calculations exclude retainage receivable, others include it. Either way, retainage typically adds 30-60 days to DSO and should be tracked as a separate metric. We cover this in the retainage post.

How fast can I improve DSO?

Most contractors see 10-15 days of improvement in the first 90 days of disciplined collections and billing. Full improvement to a 40-55 day target typically takes 6-12 months and depends on customer mix and contract terms.

How does DSO affect cash flow forecasting?

DSO is one of the four inputs that determine accounts receivable collection timing in any cash forecast. A 10-day DSO improvement on a $20M business pulls roughly $500K of cash forward over the rolling 13-week forecast.

Civil CFO is the construction-pure Fractional CFO firm. Every CFO on our team has actually sat in the CFO seat at an 8 or 9-figure contractor. We work exclusively with $10M-$70M construction companies, single-owner and family-owned, trying to move from 1-3% net margin to 10%+ and build enterprise value that compounds.

If your DSO is over 60 days and you can’t point to the exact causes on one page, you don’t have a “construction is slow-pay” problem, you have a finance operating system problem.

That’s where we come in. If you’re a $10M–$70M contractor and you want a construction‑pure Fractional CFO to build and enforce a DSO discipline your accounting team can run without you, schedule a Strategy Call.

The owner of a $19M mechanical contractor brought us in last spring because his banker had asked him a question he couldn't answer.

The banker was reviewing his trailing 12 months of financials. "What's your direct labor as a percentage of revenue?"

The owner pulled up his P&L. His direct labor line said $4.2M. His revenue said $19.1M. He did the math: 22%.

The banker frowned. "Industry benchmark is closer to 32-35% for your work mix. Why are you so low?"

The owner didn't know. We did.

His chart of accounts had been set up by his bookkeeper in 2014 on a template designed for a plumbing repair shop. His "Labor" line was mixing direct field crews with supervisors with project managers with shop guys. His "Payroll Taxes" line wasn't allocated anywhere. His "Benefits" account included both his crews and his wife's family health plan.

His banker was reading 22% labor cost. His actual direct labor cost, calculated correctly, was 31.4%. Right in the industry benchmark.

That sounds like an accounting nit. It wasn't. He was using the 22% number to set bid markups. He was using it to plan hiring. He was using it to compare against competitors. Every operating decision he'd made for three years had been built on a number that wasn't actually his number.

The chart of accounts is not just a bookkeeper's filing system. It's the structure your entire financial picture sits on top of. If it's wrong, every number you read is wrong. Let's dive in.

What a chart of accounts actually is (in owner terms)

The chart of accounts (your accountant might call it the COA) is the list of every line where money can be recorded in your business.

Every dollar that comes in or goes out lands on a line. The lines roll up into categories. The categories produce your P&L and your balance sheet. The P&L and balance sheet are what you, your banker, your surety, your CPA, and (someday) a buyer read to understand your business.

If the lines are wrong, the categories are wrong. If the categories are wrong, the P&L is wrong. If the P&L is wrong, every decision built on it is built on the wrong number.

This is why owners who walk into a Fractional CFO conversation are sometimes surprised that one of the first things we look at is the chart of accounts. It's not exciting. It's not strategic. It's foundational. And it's wrong in most $10M-$70M construction businesses we've worked with.

The five signs your chart of accounts is broken

You don't need to read your COA to know if it's wrong. Five signs in your business will tell you.

Sign 1: Your P&L doesn't show gross margin by division

If your monthly P&L shows one revenue line and one big "expenses" line at the bottom, your COA is set up for a small business, not a construction business.

A working construction P&L shows revenue by division (civil, commercial, service work, whatever your major work types are) and direct costs by the same divisions. Gross margin shows up by division. Without that view, you can't tell which work is actually profitable. The aggregate number hides everything.

We covered this dynamic in our profit margin benchmarks post. The owners who run 10%+ net margin businesses can tell you their gross margin by division off the top of their head. The owners who can't, can't.

Sign 2: Your job cost reports don't agree with your P&L

You pull a job cost report. It says you made $148K on the Westbrook job. You pull the P&L for the same period. The numbers don't tie. You ask your bookkeeper why. She shrugs.

This is one of the most common signs of a broken COA. The job cost system and the GL aren't talking. Usually because direct costs and indirect costs are mixed in the same accounts, and the job costing system is making different assumptions than the financial statements.

This is one of the patterns we covered in our breaking through the $10M wall post. When the structures don't match, neither number is trustworthy. You're operating blind.

Sign 3: Your banker or surety asks questions you can't answer

The banker asks about your direct labor percentage and you can't tell him. The surety asks about your shop overhead and you don't know where to find it. Your CPA's year-end financials look different from your monthly internal financials.

These are signs your COA isn't producing the cuts of data your external partners need. A well-structured COA produces the same answer no matter who's asking. A broken one produces different answers from different reports.

Sign 4: Your year-end financials always come with big surprises

Every March, your CPA finishes the year-end financials and the numbers look meaningfully different from the monthly P&Ls you'd been reading. Inventory adjustments, WIP adjustments, expense reclassifications. The CPA needs to make significant journal entries to get the year-end statements to look right.

Big year-end adjustments usually mean the COA structure isn't producing reliable monthly numbers. The annual cleanup is patching what the monthly process couldn't catch.

Sign 5: Your monthly close takes 20+ business days

A clean COA, paired with disciplined accounting, produces a monthly close within 10-15 business days. When closes are running 20+ days every month, something in the underlying structure is fighting the process. Often the COA is part of the problem.

What gets distorted when the COA is wrong

Five operating consequences when your COA is broken. We see them constantly.

1. Your gross margin is misleading. You bid the next job based on a gross margin that isn't your actual gross margin. The bid is structurally too low or too high.

2. Your overhead looks bigger than it is. Direct costs are hiding in overhead. You spend energy cutting administrative costs that aren't the problem.

3. Your job costing lies to you. PMs get evaluated on margins that don't reconcile to the GL. The accountability conversation is impossible because the data isn't trustworthy.

4. Your bonding agent reads you wrong. Working capital, current ratio, and net worth calculations come out distorted. Your bonding capacity ends up lower than your business actually warrants.

5. Your enterprise value takes a hit. When you eventually sell (or even just go for major financing), the buyer's or lender's due diligence finds the structural issues and discounts the price. We covered the valuation dynamic in our construction company valuation post.

This isn't theoretical. We've seen contractors lose 1-2 turns of EBITDA multiple at sale because their financial statements told a confusing story. For a $25M business at $2M EBITDA, that's $2M-$4M of enterprise value lost. From accounting structure.

What a good construction COA produces

You don't need to know the account numbers. You need to know what a good COA should give you. Six things:

1. Revenue cleanly broken out by division (or project type, or however your business naturally segments).
2. Direct costs broken out the same way as revenue, so gross margin by segment is visible.
3. Labor and labor burden separated from each other and separated from non-construction salaries. We covered the labor burden mechanics in our labor burden post.
4. Equipment costs in their own section so you can tell what owning your fleet actually costs.
5. WIP balances on the balance sheet (the technical terms are "costs in excess of billings" and "billings in excess of costs"; they're what ties your WIP schedule to your financial statements). We covered the WIP mechanics in our WIP schedule post.
6. Retainage receivable tracked separately from regular accounts receivable.

When your COA produces these six things, your monthly financials become decision-quality. Your banker, your surety, your CPA, and (eventually) a buyer all read the same story. Your job cost reports tie to the GL. Your gross margin is the truth.

When to rebuild and when to leave it alone

Not every messy COA needs to be rebuilt. The question is whether the gap between what your COA produces and what you need it to produce is hurting decisions.

Rebuild signs:

• Your job cost reports don't reconcile to the GL
• Your gross margin by division is invisible
• Your banker or surety asks questions you can't answer
• You can't tell what your labor cost ratio is
• Year-end CPA adjustments are large or surprising
• You can't produce clean monthly internal financials

Leave it alone signs:

• Your financials produce decision-quality reports
• Your CPA, banker, and surety all read the same numbers
• Your team produces monthly reporting within 10-15 business days
• Your job costs and your GL agree

A COA rebuild is a 60-120 day project for most $10M-$70M contractors. It's painful in the short term. It also produces 12-24 months of structural reporting improvement and is a prerequisite for almost every other CFO-level project.

Who should be doing this work

The COA design is not the owner's job. It's also not the bookkeeper's job alone. Here's the right split:

• The owner's job: Recognizing the signs. Knowing what a good COA should produce. Funding the rebuild if needed.
• The Fractional CFO's job: Defining what the reports need to produce. Specifying the structural requirements. Coordinating with the CPA on tax implications. Pressure-testing the output once it's built.
• The senior controller or accounting team's job: Designing the underlying account structure based on the requirements. Implementing the structure. Coding transactions correctly going forward.
• The CPA's job: Reviewing for tax compliance. Producing year-end financials within the new structure.

When this split is clean, the rebuild takes 60-120 days and produces structural reporting improvement for years. When it's not clean (usually because the owner is trying to direct accounting, or the bookkeeper is trying to do CFO-level reporting design without the strategic context), the rebuild stalls and the same problems return six months later.

The conversation to have with your accounting team

Three questions worth asking your accountant or controller this week:

1. Can you show me my gross margin by division for the last three months? If they can produce this in 10 minutes from existing reports, your COA is probably fine. If they need to manually build it, the COA isn't structured for it.
2. Do my job cost reports tie to my GL? If yes, your structure is working. If the answer is "mostly" or "with adjustments," you have a gap worth diagnosing.
3. What would it take to produce decision-quality monthly financials within 10-15 days of month-end? If they have a clear answer, good. If the answer is "more time" or "different software," you may have a structural issue.

These three questions surface the diagnosis most owners don't know how to ask.

What we do with the chart of accounts at Civil CFO

We don't do bookkeeping or accounting at Civil CFO. The actual COA build and implementation is your accounting team's work.

What we do in every engagement:

1. Audit the current COA in the first 60 days as part of the initial diagnostic
2. Identify the structural gaps that are preventing decision-quality reporting
3. Specify the structural requirements for a rebuild if one is warranted, then coordinate with your accounting team (in-house or outside) who actually builds the new structure
4. Pressure-test the financial reporting monthly on the Strategy Call to make sure the structure is serving the business

A COA rebuild done with a Fractional CFO advising on the requirements produces a different result than one done by the bookkeeper alone. Not because the bookkeeper isn't capable. Because the COA needs to be built backwards from the reports an owner needs to make decisions, and that's the CFO seat's job to define.

The construction industry averages 5-6% net profit. Top-quartile contractors hit 10-12%. That gap, five points on every dollar, is the difference between a business that funds growth and one that funds your stress.

The thing is, most contractors don't actually know which side of that line they're on. They know what their revenue is. They know what their bank balance looks like. They have a vague sense that things are "going pretty well" or "tighter than it should be."

Then year-end comes, the financials hit the desk, and the net margin number lands somewhere between 2% and 4%. Womp womp.

The owner stares at it and thinks the same thing he thought last year. "I need to grow."

Here's the truth: growing revenue at 3% net just amplifies the chaos. You can't growth-out of a margin problem. You have to fix the margin.

Let's dive in.

The numbers that matter

Two numbers to get straight before we go any further:

Gross margin (GP%) = (Revenue − Direct job costs) ÷ Revenue. Job costs being labor, materials, subcontractors, equipment, and direct project overhead. This is the project profitability number.

Net margin = (Revenue − All costs including G&A) ÷ Revenue. After everything. This is the business profitability number.

Sometimes you'll also hear about EBITDA margin. Earnings before interest, tax, depreciation, and amortization. That's closer to a true cash profitability picture for the business, and it's the one M&A buyers care about. But for most operating decisions, gross margin and net margin are the two to track.

Now the industry benchmarks. These are pulled from a combination of CFMA annual financial benchmarking surveys, FMI Corporation industry data, and AGC reports. The numbers move a little year to year, but the patterns are remarkably consistent.

A few patterns worth noting:

• Specialty trades carry higher gross margins than GCs. They're putting their own labor and markup on the work instead of subbing it. The tradeoff is operational complexity.
• Civil tends to outperform commercial GC on net margin. Equipment-heavy, but the pricing power on heavy civil work is structurally better.
• Residential remodelers post the highest gross margins but also the highest overhead drag and lowest backlog visibility. Different shape, similar end profit number.
• Top quartile is roughly 2x the average net margin in every segment. That's not a coincidence. It's a systems gap.

Why "industry average" sucks

The temptation when you see "average net margin: 5%" is to look at your 4.5% and feel okay about it. You're close to average. Slightly below, but you're in the neighborhood.

Hard pass on that framing.

Average means you're surrounded by contractors who are running mediocre financial systems. The average pulls in the businesses that close out 30% of their jobs under bid margin. The average includes the contractor who hasn't actually run a WIP review in two years. The average includes the businesses that will go under in the next cycle.

Average is not where you want to be benchmarked. Top quartile is where you want to be benchmarked.

And top quartile isn't a magic state for businesses that are "lucky" or have some special advantage. Top-quartile contractors are running specific business systems that the average contractor isn't running. The systems are knowable. The systems are buildable. The contractors running them are pulling the industry average up while everyone else accepts mediocre numbers as normal.

Where the missing points actually go

Here's the question we ask every prospect on a discovery call:

"You bid jobs at what gross margin?" Most contractors at $10M–$70M say somewhere between 18% and 28%, depending on segment.

"What do you bank in net margin at year-end?" The answer is almost always somewhere between 2% and 5%.

So where do those 15-25 points go between bid and bank?

Six honest leaks. They're not a secret. They're just usually not measured.

1. Estimating accuracy gaps

You bid 22% GP. The job comes in at 17% actual GP. The estimator was 5 points off. Labor productivity was lower than estimated, material prices moved, the schedule slipped, subs came in higher than carried.

Average across a year, on average jobs, that's 3-4 points of margin lost before execution even starts. Top-quartile contractors run a tight estimating-to-actual feedback loop where every closed job's variance gets fed back into the next bid. Average contractors don't.

2. Profit fade

We covered this in depth in our WIP schedule explainer. Costs creep up during execution. Estimated total cost at completion drifts higher month by month. Projected GP shrinks. The contractor who catches it in WIP month two fixes it. The contractor who finds out at year-end doesn't.

Profit fade is the difference between catching the problem and absorbing it. Two to four points of margin can walk off in profit fade in a year on a poorly-run WIP cycle.

3. Change orders performed but unbilled

Field PM gets asked Thursday to add a small scope item. "Yeah, no problem." Crew does the work Friday. Nobody writes it up. Three months later the job closes. The cost is in the books, the revenue isn't. The whole margin walks.

Or change orders that are billed, but priced at cost or close to it. Because the PM wasn't paying attention to markup discipline. Change orders should be priced at the same markup as base scope. We dug into the whole pattern in our change orders and profit fade post.

Two points of margin live here for many contractors.

4. Overhead that's miscategorized

Office time spent estimating, supervising, problem-solving. That's overhead. Some of it absorbs into G&A and stays there. Some of it should be allocated to specific jobs (or to a burdened labor rate — the true cost of an hour of labor including taxes, benefits, and supervision overhead) so the job profitability accurately reflects the cost of supporting it.

Most contractors don't do this allocation cleanly. The total margin doesn't change, but the WIP and job profitability reports become misleading. The WIP looks healthier than it should, and the year-end net margin is lower than the WIP suggested all year. You can't fix what you can't see clearly.

5. Cost-of-cash on slow-paying jobs

This is the silent one. If you're financing a slow-paying customer with your own working capital, you're paying interest on a line of credit because of it. That interest is an actual cost of the job — even though it shows up as interest expense on the P&L, not as a job cost. Almost no contractor traces it back to the job. So the job looks profitable on the GP line and is actually less profitable in net terms.

A job with a 70-day collection cycle, financed off a 7% line of credit, costs you about 1.3% of contract value in interest. On a $5M job, that's $65,000. Not a rounding error.

6. Normal G&A overhead

Even a tight business carries 7-10% of revenue in G&A — office, admin, owners' comp, software, insurance, sales and marketing. That's the structural cost of running a business, and it's the biggest single gap between your actual GP and your net margin. Top-quartile contractors get G&A as a percentage of revenue down by 1-2 points through scale and discipline. Bottom-half contractors carry G&A drift — software they don't need, headcount they grew into casually, owner expenses that should be distributions instead of business expenses.

Eight to nine points sit here for most contractors.

Add it up: 3 + 3 + 2 + 1 + 9 = roughly 18 points between bid and bank. That's how 22% becomes 4%.

Now, do top-quartile contractors eliminate all of these? No. But they're systematically smaller in every category. Estimating variance is closer to 1 point. Profit fade is closer to half a point. Change orders are captured. Overhead is allocated cleanly. Cost-of-cash is managed because cash itself is managed. G&A is held to 6-7%. That's how the gap to 10%+ net gets closed.

The owner mindset shift

Here's the harder part of this conversation.

Owners stuck at 3% net think they need more revenue. The instinct is to grow out of the problem. Take on more work, win more bids, hire more PMs, expand the geography.

Owners hitting 10% net know they need better systems. Same instinct that comes through the door at every revenue level looks different depending on what the owner has figured out.

Revenue growth at 3% net just amplifies the chaos. Bigger numbers in. Bigger numbers out. Same proportional drama. More risk because you're financing more jobs at the same broken cycle. We covered this exact theme in the $10M Wall post. Most contractors plateau there for exactly this reason.

Margin growth at 3% net to 6% net on the same revenue doubles the profit. Margin growth from 6% to 9% on the same revenue increases profit by 50%. None of that requires winning new work, hiring new PMs, or expanding geography. All of that requires running the business differently with what you already have.

That's the shift. And it's the harder one because it requires the owner to stop hunting for the next bid and start fixing the system underneath the current ones.

How top contractors actually run the playbook

Six business systems. The contractors who run them well hit 10%+. The ones who don't, don't.

1. Disciplined monthly WIP review. Every active job, every month, with finance + ops + estimating in the same room. We covered the full playbook here.
2. Tight estimating-to-actual feedback loop. Every closed job's variance vs. bid gets reviewed. The estimating model improves over time. Bid quality goes up.
3. Disciplined change order management. No work starts without written authorization. Same markup as base scope. Reviewed monthly in the WIP. Captured fully. The whole framework is in our change orders and profit fade post.
4. Disciplined overhead allocation. A burdened labor rate that includes the cost of supporting the work. G&A doesn't absorb costs that should sit on jobs.
5. Rolling 13-week cash flow forecast. Cash gets managed proactively. The line of credit is a tool, not a lifeline. We covered the full build here.
6. Monthly strategic financial review. The owner sits with a CFO (fractional or full-time) once a month, looks at the forward-looking picture, and makes decisions based on data instead of instinct.

That's the playbook. None of it is mysterious. Most of it isn't even hard. It's just consistently not done in average contractors, and consistently done in top-quartile ones.

What a 5-point margin improvement is actually worth

Let's run the math.

A $30M civil contractor moving from 4% to 9% net adds $1,500,000 to the bottom line in 12 months.

Same revenue. Same crews. Same equipment. Different systems.

That $1.5M can:

• Fund a bonus pool that retains top PMs and estimators
• Cover the working capital build needed for a bonding capacity increase
• Pay off the line of credit and stop paying interest
• Fund the next equipment buy in cash instead of financing
• Get distributed to the owner (responsibly, after working capital is healthy)
• Some combination of all of the above

We worked with a contractor a few years back doing somewhere in this range who ran the playbook over 18 months. Their net margin moved from 3% to 8%. They paid out the largest bonus pool in their history and improved working capital and increased their bonding capacity 40%. Same revenue. Same people. Different systems.

We've also watched a 9-figure mechanical contractor pay out $500K in Christmas bonuses one year and underbill on three major projects so badly that the next year was a margin disaster. Both contractors had the cash. Only one had the systems.

Frequently asked questions

Is 10% net realistic in commercial GC work?

Top-quartile commercial GCs hit 8-11% net consistently. The structural margins are tighter than civil or specialty trades, but the system discipline matters just as much. We've seen $50M commercial GCs running at 9%+ net consistently. It's not the most common segment, but it's absolutely achievable.

What's a healthy gross margin for civil construction?

Heavy civil and site work contractors typically run 18-25% gross margin, with top-quartile contractors holding 22-26%. Site work specifically (utilities, grading, paving) tends to run a bit higher than heavy highway and bridge work. Equipment-heavy operations create both pricing power and overhead drag.

Why does my CPA say my margins are fine?

Your CPA is measuring you against industry tax returns, which means against the average. The average is mediocre. CPAs aren't paid to challenge your margin trajectory. That's not their lane. A construction-specific Fractional CFO is. Different relationship, different mandate, different outcomes.

How long does it take to move 5 points of margin?

Realistic timeline: 12-18 months of disciplined work. The first 90 days install the systems (WIP cadence, cash forecast, change order process). The next 6-9 months show up in cleaner job execution. The full 5-point movement usually shows up in the second year, when the system has been compounding for long enough to see the year-over-year delta. Some clients see it faster.

Can I get to 15% net margin?

In some segments, yes. Some specialty trades and residential remodelers do hit 12-15% net. For most commercial GC and heavy civil work, 10-12% is the realistic ceiling without significant scale. Don't anchor on 15% if you're in a 10%-ceiling segment. Anchor on top-quartile for your segment.

Is bigger always more profitable?

No, and this is the trap that catches a lot of contractors. Net margin doesn't scale linearly with revenue. A well-run $25M contractor can easily out-earn a poorly-run $60M one. Margin first, then growth.

If you're at 3% and your peers are at 9%, the difference isn't luck. It's six business systems.

The contractors that build them stop wondering where the money went. The ones that don't keep growing revenue and shrinking margin until something breaks.

At Civil CFO, we work exclusively with $10M–$70M construction companies trying to move from 1-3% net margin to 10%+. That entire range is exactly what we obsess over. If that's the move you're trying to make, you'll know what to do.

It's Monday morning. The owner of a $24M civil contractor pulls up his bank balance on his phone. Looks healthy. Smiles. Heads into a 9am with his estimator.

Tuesday a $180K subcontractor draw hits.

Wednesday it's bi-weekly payroll. $310K out the door.

Thursday the $220K retainage release he was counting on gets pushed three weeks because the GC's PM is on vacation.

By Friday afternoon, the line of credit is back at the cap. Again. He's not sure why. It feels like this happens every six weeks.

It doesn't feel like a cash flow problem. It feels like bad luck that keeps repeating itself.

Here's the truth: cash doesn't lie. Your P&L might. And the 13-week rolling cash flow forecast is the single tool that would have shown him this exact week was coming. Six weeks before it arrived.

Let's dive in.

Why construction cash flow is uniquely brutal

Every business has cash flow concerns. Construction has a structural cash problem that almost no other industry shares.

Six things are working against you simultaneously:

Retainage. 5-10% of every invoice gets held back for months. Sometimes a year on slow GCs. On a $5M job, that's $250K–$500K in cash you've earned but can't touch.

Progress billing. You bill once a month, on a schedule of values, with approval cycles that can run 30-45 days before the check actually shows up.

Mobilization costs. Big jobs need cash up front for crews, equipment, materials, bonds. Well before the first pay app gets cut.

Pay-when-paid. If you're a sub, you're financing the GC. If you're a GC, the same delays from the owner cascade into your subs.

Seasonal swings. Civil and exterior work has revenue mountains and revenue valleys depending on geography. Payroll doesn't get smaller in February.

Change order lag. Work performed today might not get billed for 60 days and not get paid for another 60. Meanwhile the labor and materials are out the door.

CFMA and FMI industry data has consistently shown cash flow, not bad work, not market conditions, as the single biggest cause of contractor business failure for over a decade. More contractors get put out of business by cash than by competition.

That's not because contractors are bad at construction. It's because construction cash flow is uniquely brutal, and most contractors are running it on a spreadsheet that gets opened twice a month, or not at all.

What a 13-week rolling cash flow forecast actually is

Strip away the jargon.

A 13-week rolling cash flow forecast is a weekly-updated table that shows two things:

• Cash in. Every dollar you expect to collect, by week, for the next 13 weeks
• Cash out. Every dollar you expect to pay out, by week, for the next 13 weeks

The difference is your weekly cash position. Stacked across 13 weeks, it shows you exactly when you'll have a cash trough, and how deep it'll be. Before it arrives.

It is not a P&L. Profit and loss is about whether the business is profitable on the accrual side. Cash flow is about whether the bank account stays positive in actual dollars. A business can be profitable and bankrupt at the same time. Construction is the textbook industry for this.

It is not a budget. A budget is annual, set at the beginning of the year, and updated at most quarterly. The 13-week forecast is weekly. It updates every Monday.

It is the treasury tool every other industry has been using for 40 years. And most contractors still aren't running one.

Why 13 weeks (not 4, not 26)

Why this specific window? It's a deliberate choice. 13 weeks is exactly one quarter. Enough runway to see trouble coming, short enough to stay accurate.

• Shorter than 13 weeks (4-6 weeks) and you're reactive. You can see the cliff but you can't change direction in time.
• Longer than 13 weeks (26+ weeks) and the accuracy decays. Too many unknowns. Forecasting six months of construction cash is fortune telling. We don't do fortune telling.

13 weeks gives you about 60-75 days of meaningful warning on the back half of the window. That's enough time to chase AR, accelerate billing, defer a payment, draw on a line, push out a hire, or have an uncomfortable conversation with a customer about an unpaid change order. All actionable. None reactive.

What goes on the forecast

Here's the structural skeleton of what a construction 13-week forecast actually looks like. Specific numbers in the tool itself. Here's the structure.

Starting cash position (top row, week 0. What's in the bank Monday morning)

Cash inflows by week:

• Progress billings net of retainage (by job)
• Retainage release (modeled by expected release date)
• Change orders (only ones with high probability of collection in the window)
• T&M billings
• Deposits or mobilization payments
• Customer prepayments
• Insurance reimbursements / other one-offs
• AR collections from prior-month invoices

Cash outflows by week:

• Net payroll (the payroll dates, not the wage period)
• Payroll taxes and benefits (separately. They hit different dates)
• Subcontractor draws (by job, on actual pay date)
• Vendor AP (broken down by terms. 30, 45, 60)
• Equipment payments (leases, finance, fuel, repair)
• Rent and utilities
• Insurance (workers comp, GL, umbrella, equipment)
• Taxes (quarterly estimates, sales tax, payroll tax remittances)
• Debt service (interest and principal)
• Line of credit interest
• Owner distributions (planned)
• Other recurring overhead

Net weekly cash position (inflow minus outflow)

Cumulative cash position (starting cash + running net)

Minimum cash threshold (a horizontal line you don't want to cross. Usually two weeks of operating cash for most industries; we'd argue 3-4 weeks for construction because of the structural lumpiness)

Variance to plan (what you forecasted last week vs what actually happened. This is how the model gets sharper over time)

That's the structure. The hard part isn't the structure. The hard part is feeding it the right inputs every Monday.

The construction-specific lines most templates miss

This is where most free 13-week templates fall apart for construction. They were built for SaaS or distribution. They miss the lines that move construction cash:

Retainage release, modeled by expected release date. Most templates treat retainage as a footnote. In construction it can be 5-10% of every invoice, sitting somewhere, for months, with a specific release trigger (substantial completion, final completion, lien releases). Each chunk of retainage needs its own expected release week. Otherwise the back half of the forecast is fiction.

Change order timing. Change orders performed but unbilled. Change orders billed but disputed. Change orders approved but priced at a margin you'd never accept on a base bid. We covered the full breakdown in our change orders and profit fade post. For the forecast, the question is simple: when will this actually convert to cash? If you don't have a clean answer, don't put it in the inflows.

Pay-when-paid lag. If you're a sub on a public job, you might not see cash for 60-90 days after billing. If the GC is in dispute with the owner, you might not see it at all. Forecast realistically, not optimistically.

Seasonal labor ramp. Civil and exterior contractors carry a different payroll number in May than in February. Your forecast needs to reflect that. Don't average your annual payroll across 52 weeks and call it good. You'll be wildly off in both directions.

Mobilization cash on new jobs. Every new job that's about to mobilize has a cash chunk going out before any cash comes back in. Insurance, bonds, materials, mobilization-period labor. Add those before the first pay app, not at the same time.

Equipment financing payments by asset, not by lump sum. Equipment lines come from different vendors with different terms. Lumping them into "equipment expenses" loses precision on the weeks where two big payments overlap.

These are the lines that turn a generic forecast template into a construction forecast.

How to actually run it weekly

The forecast is worthless if it sits in a tab nobody opens. Here's the rhythm that makes it work:

Monday morning, 30 minutes:

1. Update last week's actuals. What actually came in last week vs what you forecasted? What actually went out? The variance is gold. It tells you where the model needs to get sharper.
2. Roll the bottom 13 weeks forward. Move the next week into "this week," and add a new week 13 at the bottom.
3. Update inflows. Any AR that came in or got delayed. Any new change orders approved or billed. Any retainage that released. Any new contracts where the first pay app is now scheduled.
4. Update outflows. Any new vendor commitments. Any payroll changes (new hires, raises, layoffs). Any equipment buys. Any tax payments coming due.
5. Flag any week below your minimum cash threshold. If a week dips below your floor, that's the action week.
6. Decide one action per flagged week. Push a vendor payment. Chase an AR. Accelerate a billing. Pull on a line. Have the uncomfortable conversation. Do something. The forecast is only as useful as the actions it triggers.

Done. 30 minutes a week. Owned by the controller, the bookkeeper, or the Fractional CFO. Depending on your setup.

What it surfaces in the first 90 days

Here's what happens when a contractor actually runs a 13-week forecast for the first time. We see the same pattern over and over:

Trapped cash gets found. Almost every contractor we've worked with has $200K–$800K stuck somewhere they hadn't seen. Slow change orders that weren't invoiced, retainage that should have been pushed for, AR that nobody was chasing. Not new cash. Cash that was always there. The forecast forces visibility, and the visibility finds it.

Patterns get exposed. The contractor who realized he was financing two jobs out of operating cash. The civil contractor whose Q4 was going to be 35% short on cash before he saw it 11 weeks out. The mechanical sub who'd been quietly underbilling on his largest project for two months. These aren't catastrophes. They're patterns that the forecast made visible in time to fix.

Distributions get sized correctly. Owners stop taking distributions based on instinct and start taking them based on what the cash position can actually support. Sometimes that means smaller distributions in the short term. It also means no surprise tax bills and no "should we pull from the line for our own paycheck" conversations.

The line of credit gets used as a tool, not a lifeline. Forecasting in advance is the difference between strategically drawing on a line to bridge a known cash gap and reactively drawing on a line because Friday's payroll is going to bounce. Same draw, two completely different stories to your banker.

The owner stops worrying about Friday. This sounds soft but it's the biggest one. When the cash picture is visible 13 weeks out, the constant low-grade anxiety about payroll, AP, and the bank balance goes away. The owner gets sharper on the strategic decisions because his head is no longer half-occupied with whether next Friday will clear.

Frequently asked questions

Can I run a 13-week forecast in Excel, or do I need software?

Excel works. Most of our clients run their forecast in Excel or Google Sheets. There's good software for it (Float, Cashflow Frog, even Jirav and a few construction-specific tools), but software doesn't replace the discipline of the Monday update. Get the discipline first. Add the software later if it earns its place.

Who owns the forecast. Me, my controller, or my Fractional CFO?

The bookkeeper or controller usually owns the mechanics. Updating the model with last week's actuals and rolling it forward. The Fractional CFO owns the interpretation. What's the model telling us and what action are we taking this week. The owner reads the output and signs off on the actions. That three-seat structure works.

How accurate should the forecast be?

Weeks 1-4: aim for ±5%. Weeks 5-8: ±15%. Weeks 9-13: ±25%. The accuracy decays as you push out. That's expected. Anyone telling you they can forecast week 11 within ±5% is lying or guessing.

What's the minimum cash threshold?

Two weeks of total operating cash is the textbook answer. We'd argue 3-4 weeks for construction because of the structural lumpiness. One bad week of payroll plus subcontractor draws plus an insurance payment can eat a month of "normal" cash. Build an honest floor, not a comfortable one.

Do I really need this if my books are healthy?

If you've never had a cash surprise that scared you, maybe not yet. If you've had even one in the last 12 months, you needed this six months ago. The cost of running it is negligible. The cost of not running it shows up in a single bad week.

Cash doesn't lie. Your P&L might.

If you've been running your business by checking your bank balance and hoping next Friday cooperates, you don't have a cash flow problem yet. You have a visibility problem. The cash flow problem comes next.

At Civil CFO, the 13-week rolling cash flow forecast is one of the first things we install during onboarding. Typically delivered in draft inside the first week. We work exclusively with $10M–$70M construction companies trying to move from 1-3% net margin to 10%+. If that's the gap you're trying to close, you'll know what to do.

The Zoom call is six minutes in. The owner of a $19M commercial GC asks a simple question:

"Can you tell me what our gross margin was on the Johnson job?"

Long pause from the bookkeeper.

"I can run a report and get back to you tomorrow."

That's the gap.

It's not that the bookkeeper is bad. The bookkeeper is fine. She's doing exactly the job she was hired to do — record transactions, reconcile accounts, close the month. The problem is the owner is asking CFO questions and getting bookkeeper answers. And he's been doing it for two years.

If you're shopping for finance help in your construction business and you can't tell whether you need a bookkeeper, a controller, or a fractional CFO, you're in good company. Most contractors at $10M+ have this exact confusion. Let's clear it up.

Let's dive in.

The three roles, in one table

Here's the high-altitude view. We'll go deeper on each below.

Now the details.

What a construction bookkeeper does — and doesn't do

The bookkeeper is the foundation. Get this wrong and nothing above it works.

What they own:

• Recording every transaction in the books — AP, AR, payroll, journal entries
• Bank and credit card reconciliations
• Monthly close (with help from the controller or CPA at the higher end)
• Categorization of expenses
• 1099 prep, basic compliance support
• Filing — clean digital paperwork, organized vendor files

What they don't own:

• Forecasting cash
• Strategic recommendations
• WIP at a strategic level (they might build the schedule, but they're not running the monthly WIP review with operations)
• Talking to your surety or bank
• Telling you which jobs to chase
• Building the year-end story for your CPA or your bonding agent

A good construction bookkeeper saves a contractor a lot of pain. A great one is gold. But she's not the person who's going to tell you that you've been underbilling on a $4M job for two months. She's not paid to look up.

What a construction controller does — and doesn't do

The controller is the bridge. If the bookkeeper owns the transactions, the controller owns the process.

What they own:

• Faster, cleaner monthly close (5-10 day close instead of 25-day close)
• AR and AP processes — collections discipline, payment terms enforcement
• Job costing integrity — making sure costs hit the right jobs in the right buckets
• WIP schedule accuracy
• Variance analysis (budget vs actual at the job and company level)
• Coordination with the CPA at year-end
• Internal controls and approval workflows
• Cash visibility (here's the bank balance, here are the open AR/AP totals)

What they don't own (in most contractors):

• Forward-looking cash forecasting
• Capital strategy (debt structure, equipment decisions, distribution policy)
• Sitting in front of the bonding agent on capacity strategy
• Translating financials into owner-decisions ("here's what this means for next quarter's hiring plan")
• Pricing strategy or bid markup recommendations
• Leadership development of the finance team

A strong controller will absolutely flex into some of this. We've worked with controllers who are functionally doing 30% CFO work. But the seat itself isn't strategic — it's operational excellence in finance. The roles overlap on the edges. They are not the same job.

Most construction controllers cost between $100K and $160K all-in. In-house. Full-time. If your business isn't big enough to keep a controller busy with controller work (and at $10M with clean books you might not be), you're either overpaying or your controller is doing bookkeeper work for controller money. Neither is great.

What a construction Fractional CFO does

This is where the seat changes.

A Fractional CFO is forward-looking. The bookkeeper and controller are reading the financials after they happen. The CFO is making decisions about what should happen next.

What we own at Civil CFO:

• The 13-week rolling cash flow forecast: a weekly-refreshed treasury tool that shows exactly when cash is coming in and going out, by week, for the next quarter. Most contractors are still running cash off a checkbook balance and instinct. Oof.
• WIP-to-strategy translation: owning the monthly WIP review meeting with operations and estimating. Reading the WIP schedule not as accounting paperwork but as the operating gauge it actually is. We cover this whole topic in our WIP schedule explainer.
• Bonding strategy: modeling working capital, building the year-end story, prepping the surety meeting with the owner instead of dropping him in front of the bonding agent solo.
• Capital allocation: equipment, debt, distributions, retained earnings. Tax-optimal is one lens. Strategic is the broader one.
• Owner partnership: being the financial brain in the owner's corner on every meaningful decision. Hiring. Equipment buys. Major bids. Customer concentration. M&A. The stuff a CPA isn't built to do and a controller isn't paid to do.
• Leadership development of finance: coaching the controller and bookkeeper so the whole function gets sharper over time.

And here's the moat — every Fractional CFO on the Civil CFO team has actually sat in the CFO chair of an 8- or 9-figure contractor. Not consulted to one. Not audited one. Sat in the seat. That's not a marketing line. It's the hiring bar.

If you want the full breakdown of when to consider this for your business, we covered it in our signs you need a fractional CFO post.

The order to build the stack

You don't build this from the top down. You build it from the bottom up. And construction has a slightly different sequence than other industries.

Step 1: Get the bookkeeping right.

Non-negotiable. If transactions aren't being recorded correctly, no amount of strategic work above it matters. Get a bookkeeper who actually understands construction — job costing categories, AIA billing, retainage, percentage of completion. A generalist bookkeeper at a $15M contractor will create more mess than they clean up.

Step 2: Decide if you need a controller.

This is where construction breaks from the textbook. Most $10M–$25M contractors can run with a strong bookkeeper plus an outsourced accounting firm doing controller-level work (instead of a $140K full-time controller). You're paying for the controller function without paying full-time controller comp. That's often a better economic answer until you hit $25M+ where the transaction volume and complexity justify the full-time seat.

Some contractors at this size hire a controller anyway. That works too, as long as the role is sized to the work.

Step 3: Layer in a fractional CFO when forward-looking decisions are piling up.

If you're already at the point where you're losing sleep over cash, equipment buys, bonding capacity, and strategic hires — and your CPA isn't really the person to bring those questions to — you're ready for a Fractional CFO. You don't have to wait until your books are perfect. A good Fractional CFO will help you tighten the bookkeeping along the way.

The mistake most contractors make is skipping straight from bookkeeper to full-time CFO. That's expensive, slow to hire for, and usually overkill at $10M–$50M. Fractional gets you the same caliber of thinking at a fraction of the cost.

When the lines blur — and why most contractors get it wrong

Here's where we see contractors burn money:

• A bookkeeper getting paid like a controller. Title inflation. Same work, bigger paycheck. We've walked into businesses with a $90K "controller" who's functionally a bookkeeper. Owner thinks the controller role is filled. It isn't.
• A controller getting asked to do CFO work. This one's more common. Smart, capable controller gets pushed up into forecasting, strategy, bonding meetings — and is doing decent work, but is doing it part-time, in addition to her actual job, with no peer to pressure-test the thinking. The work gets done. It doesn't get done well.
• A CPA being used as a CFO. Different lane. CPAs are tax-and-compliance experts. The ones who can think strategically about your operations are rare, and the ones who can do it inside the relationship with your business are rarer still. Don't ask your CPA to be your CFO. Ask your CPA to be a great CPA.
• A "fractional CFO" who's actually a senior controller in disguise. This is the trap. A lot of fractional CFO firms hire ex-controllers and call them fractional CFOs. They build clean financial reports. They don't drive strategy. We've replaced more of these than we can count.

The seats are different. The work is different. The people are different. Pay for the seat you actually need.

Frequently asked questions

Can my CPA do CFO work?

Some can, most can't, and the structure doesn't support it even when the person could. CPAs are billing tax work and audit work — there isn't margin in their model for someone to be embedded in your monthly operations the way a CFO needs to be. Different role, different relationship.

Can I have a controller AND a fractional CFO?

Yes — and at $25M+ it's often the right structure. Controller owns the books and the process. Fractional CFO owns the strategy. They work together. We have several clients exactly like this.

What if I already have a part-time CFO who isn't construction-specific?

Have an honest conversation about percentage-of-completion, WIP, retainage modeling, bonding strategy, and job costing methodology. A generalist fractional CFO can do parts of this work, but construction is the single most financially complex industry at any revenue size. A SaaS or ecommerce Fractional CFO will be guessing on the construction-specific pieces. We covered the signals you've outgrown a generalist setup in detail.

How much should I be paying for each role?

Bookkeeper: $50K–$80K in-house, or $1K–$3K/month outsourced. Controller: $100K–$160K plus burden. Fractional CFO (construction-specific): $4K–$20K/month, with most $10M–$70M contractors landing in the $10K–$15K range. We broke down what drives the spread in our fractional CFO cost guide.

Do I need all three?

Not necessarily. The minimum stack for a $10M contractor is a great bookkeeper plus an outsourced controller-equivalent (CPA firm or accounting services firm). The CFO layer is added when the strategic load justifies it. Most $25M+ contractors run all three. Below that, you can usually run a two-tier stack.

We don't do bookkeeping. We don't do tax. We don't close your books.

We do the work between your books closing and your business growing.

If you've got the books handled and the strategic decisions piling up — equipment buys, bonding, cash, margin, hiring — Civil CFO is built for exactly that gap. We work with $10M–$70M construction companies trying to move from 1-3% net margin to 10%+. If that's the move you're trying to make, you'll know what to do.

It's Wednesday at 6:47 PM. The owner of a $22M civil contractor is sitting in his truck in the office parking lot, scrolling his bank app for the third time today.

Payroll is Friday. The number staring back at him says it's going to be close.

He's not worried about whether the business is profitable. He just closed out a strong April. Backlog is solid. Three jobs in mobilization, two more in active billing. By every measure he can think of, the company is fine.

So why does he keep refreshing the app?

Because he doesn't actually know if Friday is going to clear without tapping the line of credit. And that gap — between knowing the business is fine and knowing exactly how Friday will play out — is the gap.

It's also why he's going to Google "Fractional CFO for construction companies" sometime in the next two weeks.

Let's dive in.

The signal isn't revenue. It's blind spots.

Most articles on this topic anchor on a number. "Are you at $10M? Time to hire a CFO."

Hard pass on that framing.

We work exclusively with $10M–$70M construction companies. So yeah, $10M is a useful shorthand. But the actual trigger isn't the revenue number. It's the visibility loss that almost always shows up somewhere between $8M and $50M.

Some contractors hit it at $8M. Six active jobs, two PMs, an estimator, a bookkeeper who doubles as office manager — and absolutely no way to see how each individual job is performing in real time.

Other contractors make it to $20M before the wheels really come off. Usually because the owner is so deep in the day-to-day that the visibility problem is invisible to him. He thinks the chaos is normal because he's been swimming in it the whole way up.

The trigger isn't the size of the business.

It's the moment the owner can't answer simple questions about his own company without pulling someone aside and saying "Can you go pull a report and get back to me?"

If that's the answer on three out of five questions a banker, surety, or CPA asks, you've crossed the line.

8 signs you've outgrown your finance setup

We've seen these in almost every contractor we work with — in some combination, in some order. Be honest with yourself here. Three or more out of eight, and you're not imagining things.

1. You're surprised by cash more than once a quarter

Cash surprises happen. One a year is the cost of doing business in construction. One a quarter is a pattern. Three in six months is a system problem.

The cash isn't lying. The visibility into the cash is lying. Most contractors at this size are running cash off a checkbook balance and a vague sense of what's coming in. That's a hope. Not a system.

2. Your bookkeeper closes books but nobody owns the financial picture

This one's quiet but it's the most common.

Your bookkeeper closes the month. Maybe she's great at it. The financials get sent to the CPA. The CPA does the tax work and disappears until next quarter. Somewhere in the middle, nobody is actually reading the financials and translating them into decisions.

Closing books is a clerical job. Owning the financial picture — what does this month tell us, what does it mean for next month, what should we do differently — is a strategic job. They're different jobs. Most contractors at $10M+ have someone doing the first one and nobody doing the second one.

3. Your surety asked for something you couldn't deliver fast

Bonding agents don't fish — they request. When they ask for something specific and it takes you two weeks to produce it, they make a note. "This contractor's books aren't where they need to be."

That note costs you capacity at the next renewal. Sometimes it costs you single-project capacity on a job you wanted to bid this quarter.

If your surety has had to chase you for a current WIP schedule, a clean year-end financial, or a 13-week cash forecast in the last 12 months, the message you're sending is bigger than the document you sent late.

4. You can't tell which jobs are actually winning until they're nearly done

You bid jobs at 25% gross margin. You bank somewhere around 4-6% net. Somewhere in there is a story you can't tell.

If we asked you right now to rank your five biggest active jobs by current gross margin — not what you bid, what they're actually running at this week — and you can't do it, you have a job costing visibility problem.

Owners who can answer this question in real time make different decisions about manpower, equipment, and which next jobs to chase. Owners who can't are making those decisions on instinct and hoping the year-end financials cooperate.

5. You're bidding 25% and banking 3% — and you can't point to where it goes

This one is the version of #4 looked at from 30,000 feet.

Industry data from CFMA and FMI tells us 5-6 points of margin is roughly average. Top-quartile contractors hold 10%+. The gap between bid margin and banked margin is where the story lives.

If you can't name where your 22 points went — estimating gaps, change orders performed but unbilled, profit fade during execution, overhead absorbing into the wrong jobs, cost-of-cash on slow-paying jobs — you don't have a margin problem yet. You have a measurement problem. The margin problem comes next.

6. Major financial decisions feel like coin flips

New piece of equipment: $480K. Lease or buy? Cash or finance?

Hire another PM at $130K plus burden, or push another six months with the team you have?

Take the line of credit up another $500K, or run leaner through Q3?

If you've got a sinking feeling that you're guessing on these — and that your CPA isn't really the right person to ask — that's a real signal. CPAs are tax experts. Tax-optimal isn't the same as strategically right. A $50K decision made on bad framing costs you a lot more than $50K downstream.

7. You bought PM software or the ERP but still don't trust the numbers

Procore, Sage 100, CMiC, Foundation, Buildertrend, Trimble. Pick a flavor. Every contractor in the 8-figure revenue range has spent six figures somewhere in this stack.

And then somehow the WIP report still gets rebuilt in Excel every month because nobody trusts what the software spit out.

That's not a software problem. That's a process problem. The software is fine. The inputs are inconsistent. The categorization is sloppy. Nobody owns the reconciliation between what's in the system and what's actually happening on jobs.

A construction-specific Fractional CFO's first month is usually spent untangling exactly this.

8. You can describe your business in revenue but not in margin

If someone asked you tonight at dinner how the business is doing, what's the first number out of your mouth?

If it's revenue — last year's revenue, this year's expected revenue, last month's billings — you're not alone. Most contractor owners describe their business in revenue terms.

But revenue isn't the business. Margin is. Cash conversion is. Backlog quality is. Job-level GPM trends are.

When the owner can fluently describe the business in margin terms instead of revenue terms, the business runs differently. Until then, the business is running the owner.

What a construction-specific Fractional CFO actually owns

A Fractional CFO isn't a controller with a fancier title. We get asked this constantly, and the difference matters.

A controller owns the past. Reconciliations, closing the books, AR/AP processes, the integrity of the data. That work is critical. We're not knocking it.

A construction-specific Fractional CFO owns the future. Specifically:

• The 13-week rolling cash forecast. What's coming in, what's going out, by week, for the next quarter. Updated every Monday. The treasury tool every other industry has been using for 40 years and most contractors still aren't running. Learn more about this HERE.
• WIP-to-strategy translation. Reading the WIP schedule monthly with operations and estimating — not as an accounting document, but as the operating gauge it actually is.
• Bonding strategy. Modeling working capital builds, planning the year-end story, sitting in the surety meeting with you instead of leaving you to fend for yourself.
• Capital decisions. Equipment, debt, distributions, retained earnings, the right time to take a line of credit increase. Tax-optimal is one lens. Strategic is the bigger one.
• Leadership development of your finance function. Your bookkeeper or controller gets better because someone is finally giving them feedback that connects to the strategy.

And here's the thing most generic Fractional CFO firms can't claim: every CFO on our team has actually sat in the CFO seat of an eight- or nine-figure contractor. Not consulted to one. Not done audit work for one. Sat in the chair. That's the difference between someone who's read about construction finance or saw some videos on YouTube - and someone who's lived inside it.

When a Fractional CFO is NOT the answer

We turn down work that isn't a fit. It saves both sides a lot of pain.

A Fractional CFO is not the right move if:

• Your books aren't closing cleanly every month. If your bookkeeping is upstream of the problem, hiring a CFO is paying $10K-$15K/month for someone to be frustrated at your bookkeeping. Fix the bookkeeping first. Either upgrade who's doing it, or add a controller. Then look at CFO.
• You're under $5M in revenue. At that size you don't need 10-15 hours of CFO time a week. You need a good controller, a great CPA, and tight job costing. Save your money. We'd tell you the same thing on the discovery call.
• You want someone to do the financials for you instead of building the system with you. A Fractional CFO isn't a fix-it-and-leave service. The whole point is to install rigor in your business that outlasts the engagement.
• You're not willing to be challenged. We're paid to be partners, not yes-men. If you want someone to validate your plan, you don't want a CFO. You want a cheerleader. Different role.

If your books are clean, you're at $10M+, and you've got the seven other signs above showing up, then a Fractional CFO is the right next move. If you're underneath that bar, we'll happily tell you so.

Frequently asked questions

Do I need a full-time CFO or a Fractional CFO?

Most $10M–$70M construction companies don't need 40 hours of CFO work a week. They need the right outcomes. Full-time construction CFO comp runs $250K–$400K plus benefits and equity expectations, and you're paying for hours you don't need. Fractional gets you the same caliber of strategic thinking at a fraction of the cost — without the recruiting risk. The math usually flips around $80M, when complexity and capital structure justify a full-time hire. We cover this in more depth in our Fractional CFO cost guide.

What does it cost?

For construction, Fractional CFO retainers run $4K–$20K/month industry-wide. Civil CFO sits in the $10K–$15K range. We've written a full breakdown of what drives the spread here.

How long until I see results?

The first 30-60 days you'll feel visibility you didn't have before — 13-week cash forecast running, monthly WIP review installed, real-time view of which jobs are winning. Hard ROI usually shows up between months 6 and 9, depending on what the leverage points are. Margin improvements are slower than cash improvements. Both are real.

Will my CPA hate this?

The good ones won't. Good CPAs love working with a CFO because we make their life easier — clean books, organized year-end, no fire drills. The CPAs who push back are usually the ones doing CFO work they shouldn't be billing for. Different lane.

Can I have a controller AND a Fractional CFO?

Yes — and at 8-figures+, it's usually the right structure. Controller owns the books, Fractional CFO owns the strategy. They work together. Most of our clients have either an in-house controller or a strong bookkeeper plus an outsourced accounting firm doing controller-level work. We're additive to that structure, not a replacement for it.

If three or more of those eight signs describe your last 90 days, you don't have a hustle problem. You have a visibility problem.

At Civil CFO, every Fractional CFO on the team has actually sat in the CFO seat of an eight- or nine-figure contractor. We work exclusively with $10M–$70M construction companies trying to move from 1–3% net margin to 10%+. That's it. That's the whole business.

If that sounds like the gap you're trying to close, you'll know what to do.

If your construction company is stuck at $10M, you're not alone, and the problem probably isn't what you think.

We see it constantly at Civil CFO. Contractors grow fast from $1M to $5M. Many push into the $10M to $25M range. Then they stall. Sometimes for years.

Most owners assume they need more sales, more marketing, more projects. They don't. The ceiling almost never has anything to do with demand. It's that the financial systems that worked at $5M stop working once project volume, team size, and complexity compound. Instinct and spreadsheets were enough before. They aren't anymore.

The contractors that break through $10M aren't out-hustling the ones that get stuck. They build five financial systems the stuck ones don't have. Let's walk through each.

The $10M Wall Is a Complexity Problem, Not a Sales Problem

At smaller sizes, you can run a construction company on experience, instinct, and spreadsheets. You know every job personally. You're close to the field. You can feel when something's off before the numbers tell you.

Once you cross a certain threshold, that breaks. More jobs. More crews. More cash moving through the business. More risk on every project. The mental model that got you here can't process the volume.

It doesn't happen at an exact revenue number. We see it most often in the $10M to $25M range, but the trigger is always complexity, not revenue. Some contractors hit it at $8M. Some make it to $15M before the wheels come off. Either way, the pattern is the same. The business outgrows the systems running it, and the owner ends up working harder than ever just to keep the lights on.

If you're there now, you don't have a hustle problem. You have an infrastructure problem.

Here are the five financial systems that fix it.

1. Cash Forecasting: The System That Removes the Bank-Balance Surprise

Most contractors manage cash one way. They log into the bank, look at the balance, and if the number looks healthy, assume things are fine.

In construction, that's dangerous. The cash in your account is almost always already spoken for:

• Upcoming payroll
• Vendor payments
• Subcontractor payments
• Equipment purchases
• Taxes
• Insurance

Meanwhile, the cash that should be coming in is tied up in slow pay, billing delays, retainage, or disputes. That's why contractors get blindsided by cash problems even when revenue looks strong.

In plenty of cases, the issue isn't even timing. The company is structurally undercapitalized for the work it's taking on. From the outside it looks busy. Internally, the timing of cash in and cash out is a guessing game.

We worked with a $30M civil contractor last year who had a healthy bank balance going into June. Monday of the first week, payroll cleared with room to spare. Tuesday a $180K subcontractor draw hit. Wednesday a major retainage release he'd been counting on slid two weeks because the GC's project manager took vacation. By Friday his line of credit was at the cap. None of that was new information. Every piece of it was visible weeks in advance. He just hadn't built the system that would have shown him the squeeze 11 weeks earlier. A 13-week forecast caught the same pattern in his second month with us and gave him three months of warning on the next one. That's the difference between reacting to cash and managing it.

A proper cash forecasting system fixes this. Not a spreadsheet that gets dusted off when things look tight. A rolling 13-week cash flow forecast that gets updated weekly and answers the questions you actually need answered:

• When does cash get tight?
• When can we hire another crew without breaking the bank?
• Can we start that new project, or do we need to wait?
• Do we need to accelerate collections this week?

Contractors who run a 13-week forecast stop reacting to surprises. They see problems weeks or months ahead. The anxiety drops dramatically because the future stops being a black box.

There's a deeper structural problem behind the surprises too. Construction cash flow is uniquely brutal compared to other industries because of progress billing, retainage, pay-when-paid, and the lag between work performed and cash collected. The 13-week forecast is the tool that makes that structure visible week over week. Without it, even the best operators get blindsided. CFMA's annual benchmarking work on construction financial management consistently identifies cash flow discipline as one of the clearest differentiators between contractors that grow through this revenue range and contractors that don't.

This is the first system that breaks at $10M, and it's the first one to fix.

2. WIP Discipline: The System That Separates $25M Contractors From $10M Ones

The second reason contractors stall at $10M is that they don't actually know which jobs are making money.

This is where Work In Progress (WIP) becomes critical. WIP isn't an accounting exercise. Done right, it's one of the most powerful operational tools in your company. WIP ties what you've actually earned on each job to what you've actually billed. Run with a consistent percent-complete method under current accounting standards, it tells you in hard numbers whether the job is making the money you thought it would, or quietly losing it.

A disciplined monthly WIP review answers questions like:

• Is this job actually on track financially?
• Are we overbilled or underbilled?
• Are we over- or under-recognizing profit based on actual progress?
• What's hiding in this project that nobody's flagged yet?

Without regular WIP reviews, problems surface too late. A job looks profitable for months. Then suddenly it isn't. By the time it's obvious, the damage is done, and you're booking a loss you could have caught months earlier.

If you've never read a WIP schedule line by line, here's exactly how it works. Overbilling and underbilling, what each one means for your cash and your margin, how your surety reads it, and the monthly review cadence that prevents profit fade. That guide is the operational companion to this section.

The contractors that consistently grow past $10M treat WIP as a monthly operational meeting, not a financial report. Estimating, operations, and finance sit down together and review every job. That feedback loop is where the money lives, because every WIP review doesn't just protect the current job. It sharpens the next estimate.

That compounding is the difference between a $10M contractor at 3% net margin and a $25M contractor hitting 10% or better. The gap isn't luck. It's the WIP discipline behind it.

3. Job Costing: The System Most Contractors Think They Have

Ask most contractors whether they track job costs. The answer is almost always yes.

Dig deeper and the visibility usually isn't anywhere close to what they think. Costs are often:

• Posted weeks after the fact
• Allocated inconsistently across jobs
• Missing key labor or equipment data
• Missing committed costs like subcontracts, POs, or pending change order exposure

Translation: the company is making project decisions on incomplete information. Project managers are flying blind. They don't know where they stand until the job is almost over, which is to say, until it's too late to do anything about it.

A reliable job costing system changes that. Instead of looking backward, you see current job performance as work is happening. Project managers can answer the questions that actually matter:

• Are we beating the estimate on labor?
• Are material costs running higher than expected?
• Is this crew performing better than the last one on the same work?

The faster that information surfaces, the faster teams correct course. Small corrections caught early prevent the massive losses that show up at the end of the job and at the end of the year on your P&L.

Job costing is also the upstream data source for everything else. It feeds the WIP schedule, which feeds the strategy. If your job costing is broken, your WIP is broken, and every downstream decision is shaky. Most contractors don't realize this until a year-end audit surfaces a $400K profit fade nobody saw coming, including the change orders you actually performed but never billed. Womp womp.

This is the system most worth investing in early. Software helps. Discipline helps more.

4. Change Order Discipline: The Silent Margin Killer

The fourth system that breaks at $10M is change order management.

Change orders should add profit. On a healthy job, the change order margin should match or beat the base contract margin, because you're capturing scope that wasn't competitively bid. In practice, most contractors leak margin on change orders without realizing it.

Five common failure points:

1. Work performed without written authorization. The crew does it Friday. The change order paperwork never catches up. Three months later the job closes 4 points below estimate.
2. Disputed change orders that never get escalated. They sit in the project manager's inbox while the cost has already hit the books.
3. Approved scope priced at cost instead of at full markup. A small concession on rate becomes a big concession on margin.
4. Time impact not captured separately. Extended overhead and lost productivity don't show up unless someone tracks them as a distinct cost.
5. Change orders billed at job close instead of on the next pay app. Cash that should have been in your account three months ago shows up after the job is over.

We worked with an 8-figure mechanical contractor who closed a job four points below estimate. The post-mortem turned up three change orders performed but never billed, one priced at cost because the project manager was friendly with the general contractor, and a foundation-delay time impact nobody captured. Total leakage on a $4.2M job: $86K. None of that was unusual. What was unusual was that they actually built a system to catch it the next time. The job after closed at estimate. The two after that closed above. Same crews, same customer profile, same bid discipline. The only thing that changed was the change order capture process.

Every one of these failure points compounds. The full change order and profit fade playbook covers the math and the five-step process to fix it. Contractors who run a change order discipline that protects margin instead of leaking it can move 2 or 3 net margin points without changing anything else about how they bid.

This is one of the highest-leverage systems to install between $10M and $25M, because change order volume scales faster than the base contract volume. The more jobs you run, the more change orders. And the gap between disciplined change order capture and undisciplined leakage shows up in the year-end P&L every time.

5. Bonding Capacity and Working Capital: The System That Decides How Big You Can Get

The fifth system is the one most contractors think about only when it's already too late.

Your bonding capacity is the external scoreboard for how well-run your financials are. The surety is a banker in a different uniform. They read your financials, your WIP, your working capital position, and your historical profit performance, and they decide what they're willing to put behind you on the next job.

If your capacity is the ceiling on your revenue, you have a financial discipline problem, not a bonding problem.

The good news is bonding capacity is controllable. The contractors who systematically increase their bonding capacity do it through working capital build, audited financials, clean WIP, accelerated AR, and an annual surety meeting that treats the surety like a partner rather than a vendor. NASBP and the broader surety industry publish guidance on what makes their underwriters comfortable, and almost all of it comes back to the same five financial signals.

Bonding capacity sits downstream of working capital. Fix the working capital position and the bonding capacity follows.

Working capital, in strict accounting terms, is current assets minus current liabilities on your balance sheet. Practically, it's the gap between what you can collect soon and what you owe soon. Picture it as a tank. If the tank's draining faster than it fills, the P&L can look fine right up until you can't make payroll. The first definition is what your surety calculates. The second is what you feel on a Tuesday when a subcontractor draw hits before a retainage release.

Sureties read working capital as the cushion that lets you absorb a bad job. Bankers read it the same way. Owners who manage working capital intentionally end up with more access to capital, more bonding capacity, and more growth optionality than owners who don't.

This is the system that decides how big you can get and how fast. The other four systems are operational. This one is structural.

The Actual Reason Construction Companies Get Stuck at $10M

When contractors hit this stage, they almost always assume the next stage of growth requires more sales, more marketing, more projects.

It usually doesn't. The constraint isn't demand. It's the lack of financial and operational visibility, plus the lack of a system that turns that visibility into margin.

The company grew faster than the systems supporting it. Without stronger financial infrastructure, the business becomes harder to manage, not easier. Cash feels unpredictable. Profitability swings month to month. The owner carries more stress than ever, even though the company is bigger.

That's the moment better financial systems stop being a "nice to have." They become the foundation that lets the next stage of growth actually happen. Once cash, job performance, costs, change orders, and bonding capacity become visible and controllable, better decisions follow. And better decisions are what move a company from $10M to $25M and beyond.

When You Need Outside Help

Most owners stuck at $10M try to build these five systems internally. Some succeed. Most don't, because building financial infrastructure inside a contractor between $10M and $50M usually requires three things owners don't have: time, financial leadership experience at this revenue size, and an external perspective that isn't loyal to anyone's ego.

That's the gap a Fractional CFO for a construction company fills. The right Fractional CFO has actually sat in the CFO seat at an 8 or 9-figure contractor before. They've built these five systems for other companies, watched them work, and know where the landmines are.

If you're not sure whether you need one yet, here are the eight signs that say you've outgrown your current finance setup. If you're trying to figure out whether a Fractional CFO, a controller, or a bookkeeper is the right next hire, that's a different decision worth thinking through carefully. And if you're trying to figure out what a construction Fractional CFO actually costs, the math is more straightforward than most owners assume once you see the ROI on the systems above.

At Civil CFO, we're construction-pure. Every Fractional CFO on our team has actually sat in the CFO seat at an 8 or 9-figure contractor. We work exclusively with $10M to $70M construction companies, single-owner and family-owned, trying to move from 1-3% net margin to 10%+ and build enterprise value that compounds.

Our diagnostic process is built around exactly the gap this post describes. The first conversation is a sixty-minute Discovery Call where we walk through where you've been, where you are, and where you want to go. If we both agree there's fit, the engagement starts with a two-day on-site at your office. We sit with your team, walk your job site, read your WIP, look at your cash, and surface the highest-leverage problems before the first month of work begins. The work that follows is built around the five systems above, in the order that fits your specific situation. The output is one of three things on a given week: a decision that moves the company forward, a system that prevents a problem from recurring, or a conversation with you that changes how the next decision gets made.

What to Do If Your Construction Company Is Stuck at $10M

Start with the system causing you the most pain right now.

If you're constantly surprised by cash, build the rolling 13-week forecast first.

If you keep getting blindsided by job losses, fix WIP.

If your project managers can't tell you whether a job is winning or losing while there's still time to act, fix job costing.

If your year-end P&L keeps coming in below your in-progress estimates, fix change order discipline.

If your bonding capacity is the ceiling on your revenue, fix working capital and bonding strategy.

You don't need to overhaul everything at once. Pick the highest-leverage problem and solve it cleanly. Then move to the next one. Most contractors who commit to building the five systems see the constraint loosen within 6 to 12 months.

If you want help figuring out which system to attack first, or you've tried to build them internally and they keep falling apart, that's what we do.

The Bottom Line

The $10M ceiling is a financial infrastructure ceiling. The contractors who get past it build five systems: rolling cash forecasting, monthly WIP discipline, current job costing, disciplined change order capture, and a working capital and bonding strategy that earns capacity instead of hoping for it.

None of those systems require more sales. They require better visibility, better discipline, and better decisions, applied consistently over time.

At Civil CFO, we're the construction-pure Fractional CFO firm built around exactly this work. Every Fractional CFO on our team is a former actual CFO of an 8 or 9-figure contractor. We work exclusively with $10M to $70M construction companies trying to move from 1-3% net margin to 10%+ and build enterprise value that compounds.
