$700,000 IN OVERDUE PAYABLES. DEBT- BY YEAR END.
More work booked than ever before, and he wasn't sure he could make payroll. Those two facts were the same fact, and here is what it took to separate them.
A $3.4M civil subcontractor came in with $700,000 in overdue payables, four merchant cash advance loans draining $110,000 a month, and a payroll he wasn't sure he could fund, with a fuller pipeline than he had ever had. The growth was making it worse, not better: civil work demands mobilization money before a dollar is billed, and on four simultaneous jobs he was fronting that shortfall four times over. He was underbilling by 15 percent, which left roughly $500,000 in earned revenue uncollected, while collections averaged 75 days and overhead ran 32 percent against a 5 percent gross profit margin. Inside 30 days we collected $245,000 in receivables, corrected an estimating model that was underpricing every job by about 10 percent, restructured the four advances, and built a thirteen week cash flow forecast. Inside 60 days overhead was 15 percent, gross profit margin was 33 percent, the bank balance held at $45,000, and 22 new projects were booked. Same business, better system.
The thing worth taking from this one is that nothing about the work changed. He didn't start bidding differently, hire a different crew, or chase different jobs. He got an accurate read on his own numbers, and every decision after that got easier.

A FULL PIPELINE AND NO MONEY TO RUN IT.
A $3.4M civil subcontractor came to us with $700,000 in overdue payables, four merchant cash advance loans costing $110,000 a month, and a payroll he wasn't sure he could make. His pipeline was full. He had more work booked than ever before.
That's not a coincidence. The growth made it worse.
If you're a civil subcontractor and you feel like every new project creates a new cash problem, you're not doing something wrong. You're experiencing what happens when a growing subcontracting business runs on the wrong financial system. More work amplifies every timing lag, every billing delay, and every dollar of retainage sitting uncollected. The business looks healthy from the outside, and the bank account tells a different story.
WHY GROWING CIVIL SUBS HIT CASH WALLS.
Civil work is capital-heavy by nature. Mobilization costs hit before you bill a dollar. Equipment, fuel, materials, and labor go out the door in week one, and your first pay app might not get approved and paid for 60 to 90 days. On a $400,000 earthwork contract, you might be $80,000 in the hole before you see your first check.
On one job, that's manageable. On four jobs running simultaneously, which is what growth looks like, you're fronting that shortfall four times over. Your overhead doesn't pause while you wait for payment. Payroll goes out every week, fuel bills come due, and equipment payments don't care what your GC's payment cycle is.
This owner wasn't underbidding. His jobs were priced to make money. But he was underbilling by 15 percent, meaning he consistently invoiced for less than the work he had completed. On a $3.4M revenue base, that's roughly $500,000 in earned revenue he hadn't collected yet, sitting in underbilled work, invisible on his income statement, while real costs kept hitting his bank account.
THE PAY-WHEN-PAID TRAP IN CIVIL WORK.
Most civil subcontractors work under pay-when-paid terms. In practice that often means 60, 75, or 90 days between completing work and receiving payment, and that's if there are no disputes, no missing lien waivers, and no rejected pay apps.
This owner was averaging 75 days to collect. That's two and a half months of completed work floating in accounts receivable while his crew kept working and his vendors kept sending invoices.
Here's the math on why this kills cash flow even on profitable jobs. If you do $300,000 a month in civil work and your average collection is 75 days, you have roughly $750,000 in earned but uncollected revenue at any given time. That money is real and it will eventually hit your account. It's not available today, when your equipment rental is due, your concrete supplier wants payment, and payroll runs Friday.
Growing faster doesn't solve this. It makes it worse.
WHAT MOST CIVIL SUBS MISS, THE OVERHEAD CREEP PROBLEM.
When civil subcontractors grow, overhead grows with them. A second foreman. A project coordinator. More equipment, and a bigger yard. These are reasonable investments in capacity, and they change your break-even math in ways most owners don't track week by week.
This owner was running 32 percent overhead against a 5 percent gross profit margin. He was subsidizing operations with cash advances and debt, borrowing money to cover the difference between what his jobs produced and what the business cost to run.
A healthy civil subcontractor in the $2M to $8M range should be somewhere in the 12 percent to 18 percent overhead range. Above 25 percent you're in trouble. Above 30 percent you're probably already borrowing to survive, and you just might not have called it that yet.
WHAT FIXING IT LOOKED LIKE.
Within 30 days we did four things.
We collected $245,000 in outstanding receivables. Not by doing anything exotic, but by building a collections process, following up systematically on aging invoices, and submitting corrected pay apps on jobs that had been underbilled. That money existed. It just hadn't been collected.
We fixed the estimating model. Every job had been underpriced by roughly 10 percent because overhead wasn't being allocated correctly, and fixing the estimate structure meant future work would produce the margins it was supposed to.
We restructured the debt. Four merchant cash advances at predatory rates were renegotiated, and the $110,000 monthly drain became manageable.
We built a thirteen week cash flow forecast. For the first time, the owner could see when money was coming in and going out. Knowing a cash shortfall is coming three weeks in advance gives you options. Getting surprised by it on a Thursday before payroll doesn't.
PROFITABLE JOBS CAN STILL DRAIN CASH.
Here's what most civil subs don't understand until they've lived it. A job can be profitable on paper at a 22 percent gross margin and still cost you cash.
If you mobilize $60,000 on a $280,000 contract in month one, bill $40,000 because you're behind on your pay app, and don't collect that $40,000 for 70 days, you've spent $60,000 and collected nothing in the first three months of that job. The job is profitable. The business is cash-negative.
This is why a P&L statement alone doesn't tell civil subs what they need to know. Profit is an accounting concept. Cash is what pays your crew on Friday, and the distance between the two is where civil subcontractors get into trouble.
WHAT THE BUSINESS LOOKS LIKE NOW.
Within 60 days, overhead dropped from 32 percent to 15 percent. Gross profit margin went from 5 percent to 33 percent. The owner went from scrambling for payroll every two weeks to keeping a consistent $45,000 in the bank.
He booked 22 new projects, because he finally knew what his numbers were. He's on track to be completely debt-free by end of 2026. Same business, better system.
THE SHORT LIST.
