We had a Monthly Strategy Call last fall with a $34M commercial GC. He was tracking backlog the way most owners do: one number, on a sticky note, updated whenever he remembered.
"We've got $42 million in backlog," he said. "Best year I've ever seen."
We asked five questions.
How much of that is signed? How much is verbal commitments? How much is repeat customer versus new? What's the average margin in the backlog versus your trailing margin? And when does each piece of work hit the calendar?
He had answers to none of them. Which means his $42 million in backlog was a feeling, not a number.
Three months later, two of the verbal-only jobs went elsewhere, and one signed job pushed eight months because the customer's financing fell through. His actual workable backlog turned out to be closer to $26 million. That's a $16 million swing in the forward picture, and he had built his hiring plan, his equipment purchases, and his bid pipeline on the $42 million number.
This is what backlog management without discipline does.
Let's dive in.
Backlog is the value of contracted work that hasn't been completed yet. It's the work you've already won but haven't yet billed or built.
The textbook formula is:
Backlog = Total contract value of all signed jobs minus revenue already recognized (or billed) on those jobs
That's the number that goes on bonding applications, financial statements, and bank covenant calculations.
That number is also almost useless for operating decisions. Because it's a single static figure that says nothing about timing, mix, margin, or risk.
A working backlog report (the kind we build with every Civil CFO client) shows seven dimensions, not one.
Signed work is contracted, with a PO or executed agreement. Verbal work is a customer who's said yes but hasn't signed. The conversion rate from verbal to signed is never 100%. For most contractors it's 70-85% depending on customer type and the maturity of the relationship.
Most owners blend signed and verbal into one "backlog" number. They shouldn't. Verbal backlog has roughly a 20% discount built in for jobs that won't materialize.
Concentration risk is the silent killer in construction backlog. If 65% of your $30M backlog is one customer, you don't have $30M of backlog, you have a customer relationship risk that the bank and the surety will both flag.
We watch customer concentration in every engagement. Anything over 30% from a single customer needs a story.
Different work has different margins. If your backlog is shifting from a 14% gross margin division to a 9% gross margin division, your forward profitability is dropping even if revenue is growing. The aggregate backlog number hides this.
Five $2M jobs is not the same as one $10M job. The risk profile, the cash flow demands, the management bandwidth, and the bonding requirements are all different. Backlog concentrated in one or two large jobs raises execution risk.
When is each piece of work actually going to start, peak, and complete? Backlog that's all scheduled for next quarter is a hiring and cash flow problem. Backlog spread across 18 months is a planning opportunity. The aggregate number tells you nothing about either.
Estimated gross margin on every job in backlog versus your trailing actuals. If your backlog margin is 11% and your trailing actuals are coming in at 8%, you've got a 3-point fade problem you can predict ahead of time. We covered this dynamic in our change orders and profit fade post.
Some jobs in backlog have execution risk: a new customer, a new project type, a difficult site, an aggressive schedule. The CFO needs to know which jobs carry the risk so cash flow planning can absorb a margin miss.
Beyond the backlog dollar value, two ratios tell you whether your backlog position is healthy or dangerous.
Formula: Total signed backlog / Trailing 12-month revenue
This tells you how many months of revenue your pipeline represents.
These ranges are starting points, not rules. Civil contractors with longer lead times often run higher backlog ratios. Specialty trades with short job cycles run lower. The right ratio is the one that matches your work mix.
Formula: Monthly revenue / Backlog at start of period
How much of your backlog are you consuming per month versus replenishing? If you're burning $3M of backlog per month and adding $2M, you're shrinking. If you're burning $3M and adding $4M, you're growing.
The aggregate number hides this. Two contractors with the same $30M backlog can be in completely different positions: one is growing into it, the other is winding down.
Backlog feeds the WIP schedule, which feeds the 13-Week Cash Flow Forecast, which feeds operating decisions. These four documents (backlog, WIP, cash forecast, P&L) are the operating dashboard of a CFO-run construction business.
Most owners look at the P&L. Some also look at the WIP. Very few look at the backlog with discipline. Almost none look at all four in the same conversation.
When all four are running together, you can answer questions like:
A contractor running on a P&L and a sticky-note backlog cannot answer any of those questions with confidence.
Sureties look closely at backlog and work-on-hand when evaluating bonding capacity. The aggregate dollar value matters, but the composition matters more.
Heavy concentration in one customer reduces your effective capacity. Backlog with a mix of completed-job-types-you-can-prove-out increases it. Verbal backlog gets discounted heavily or excluded entirely. Backlog scheduled to peak simultaneously raises execution risk.
We covered the bonding capacity math in detail in our bonding capacity post. The summary: if you want bonding capacity to grow, you don't just need more backlog. You need defendable backlog with clean composition.
We see the same six mistakes repeatedly in $10M-$70M contractor engagements.
1. Blending verbal and signed backlog into one number. Different reliability, different risk, different conversation. Track them separately.
2. Tracking backlog dollar value only. Margin, customer mix, timing, and size are all part of the picture. The dollar value alone is misleading.
3. Updating backlog quarterly or annually. A monthly minimum cadence is required. Weekly is better in active bid season. Quarterly means you're operating on stale information.
4. Not tying backlog to capacity. $30M in backlog with three project managers might be the same operational reality as $15M in backlog with two project managers. Capacity is the constraint that nobody tracks.
5. Counting projects that haven't actually been won. "We're going to get the Riverside job" is not backlog. Until there's a signed contract or a confirmed verbal commitment, it's pipeline, not backlog.
6. Ignoring backlog margin. If the work you're winning has 200-300 basis points less margin than what you've been delivering, your forward profitability is dropping as it happens. Most owners don't see it until the P&L confirms it 9-12 months later.
In every Civil CFO engagement, backlog is one of the standard agenda items on the Monthly Sales and Operations Update Call. Here's what that conversation looks like:
This conversation, done monthly, transforms how owners think about the business. Backlog stops being a confidence-boosting sticky-note number and starts being the leading indicator of revenue, cash, and margin.
For the $34M commercial GC we mentioned at the start: six months into the engagement, his backlog reporting was on a different planet. He knew which $1.5M of his backlog was at risk of not converting. He knew his backlog margin had drifted from 11.4% to 9.8% and which divisions caused it. He knew his Q2 capacity utilization would peak at 96% and he needed to slow bid acceptance on small jobs to leave room for a $4.5M civil package he had a 70% probability of winning.
That clarity changed three decisions in the first six months:
Each of those decisions saved or made $200K-$500K. None of them were possible with a sticky-note backlog.
In every engagement, we install a monthly backlog reporting discipline within the first 60 days. That includes:
The CFO seat owns the integration of backlog into operating decisions. Your estimating team and your project managers own the underlying data. Both halves have to work for the system to function.
What's a healthy backlog-to-revenue ratio?
For most $10M-$70M contractors, 0.5x to 1.5x of trailing 12-month revenue is healthy. Below 0.5x is a forward revenue risk. Above 1.5x can be a capacity and selectivity issue.
How often should I review backlog?
Monthly minimum at the owner or CFO level. Weekly during active bid season. Most contractors review quarterly or annually, which means they're making decisions on stale information.
What's the difference between backlog and pipeline?
Backlog is contracted work that hasn't been completed. Pipeline is opportunities you're bidding or pursuing but haven't yet won. Both matter, but they should never be combined into one number.
Does verbal commitment count as backlog?
Yes, but it should be tracked separately from signed backlog and discounted appropriately. Conversion rates from verbal to signed typically run 70%-85% depending on customer type.
How does backlog affect bonding capacity?
Sureties evaluate backlog dollar value, customer concentration, project type mix, scheduled timing, and your ability to execute. Strong defendable backlog supports higher bonding capacity. Concentrated or verbal-heavy backlog reduces it.
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 you can’t tell us your signed-versus-verbal backlog, customer concentration, and forward margin in 60 seconds, your backlog isn’t a number, it’s a feeling.
If you’re a $10M–$70M contractor and you want a construction‑pure Fractional CFO to turn your backlog from a sticky note into the operating dashboard for revenue, cash, and bonding, schedule a Strategy Call.
