A contractor's money problem is almost never profitability. It is sequencing. You buy materials in week one, pay the crew every Friday, submit a pay application at the end of the month, wait for the owner's approval cycle, wait again for the check, and then wait months more for the retainage that gets released at closeout. The work is finished and profitable long before the cash for it exists. That interval, between the day a dollar leaves your account and the day the dollar it earned comes back: is the gap, and it is the most common reason a busy, well-run trades business runs out of money.
The useful part is that the gap is a measurable number, not a mood. It has a length in days and a dollar value at any moment, and both can be computed from documents you already produce: your job cost reports, your aging, and your bank statements. Once you know the number, the conversation changes. You are no longer asking a lender for help with a vague squeeze. You are asking for a facility sized to a specific, documented interval, which is a question underwriting knows how to answer.
What the gap actually is
Every trades business funds its own customers. You perform labor and install material on someone else's property, and you finance that work until they pay you for it. In effect, you are extending unsecured credit to a general contractor or an owner, at zero interest, in amounts that frequently exceed your entire net worth. Nobody describes it that way, but that is the transaction.
The gap widens for structural reasons rather than because anyone is behaving badly. Labor is paid weekly or biweekly. Material suppliers extend 30-day terms at best, and often demand deposits on long-lead items. Billing happens monthly, on a cutoff you do not control. Approval adds a cycle. Payment terms run from the approval, not from the work. Retainage sits on top of all of it. Each link is reasonable on its own; stacked, they routinely produce a 60- to 90-day interval between cost and cash on commercial work, and the specific length varies by owner, contract and trade.
Measuring your gap in days
Compute it in four pieces, using your own records rather than a rule of thumb. Days to bill: the average time between performing work and submitting it on a pay application. Days to approve: submission to approval. Days to collect: approval to funds received. Days of supplier float: the average terms your vendors actually extend you, which offsets the rest. The gap is the first three added together, minus the fourth.
Then convert days into dollars. Take your average monthly direct cost (labor, burden, materials, subcontracts) divide by 30 to get a daily burn, and multiply by the gap in days. That product is roughly how much cash the business needs standing behind it at all times just to keep running at its current volume. Most owners are startled by the figure the first time they compute it, because it usually exceeds anything they have ever held in the operating account.
| Stage | Approximate day | Cash effect |
|---|---|---|
| Mobilize, deposit on long-lead material | Day 0 | −$60,000 |
| First month of labor and burden | Days 1–30 | −$95,000 |
| Pay application submitted for $150,000 | Day 35 | No cash movement |
| Owner and architect review | Days 35–55 | No cash movement |
| Payment received, less 10% retainage | Day 65 | +$135,000 |
| Retainage released at closeout | Day 240 or later | +$40,000 cumulative |
Those figures are illustrative. Contract terms, approval cycles and closeout timing vary widely by owner, project type and jurisdiction. The shape is the point: cash goes out for two months before any comes back, and a tenth of the contract value sits unavailable for most of a year.
Why growth makes the hole deeper
This is the part that catches good contractors. Every new job consumes cash before it produces any, so growth increases the amount of capital tied up in the gap in direct proportion to volume. A business that adds 40% revenue in a year adds roughly 40% to its working-capital requirement in the same year, and it has to fund that increase out of last year's profit, which is smaller than the increase.
That is why contractors fail during expansions rather than contractions. A shrinking backlog releases cash; a growing backlog absorbs it. The failure mode looks like success right up until a payroll cannot be made, and the balance sheet at that moment usually shows a healthy receivable balance and an empty account.
The four places cash gets stuck
- Unbilled work in progress. The most expensive kind of stuck cash, because no clock has started: approval and payment intervals begin only once you bill.
- Slow or rejected billing. A pay application returned for a missing waiver rarely loses a week; it loses a full cycle, because it re-enters next month's queue.
- Approved receivables aging past terms. A collections problem with a legal backstop: lien rights and prompt-payment statutes exist in every state, with deadlines that vary considerably by jurisdiction.
- Retainage. Usually your entire net margin and then some, earning nothing while it sits, and the piece most likely to be excluded from a borrowing base.
The structures that close the gap
There is no single right instrument. There is a right match between the shape of the need and the shape of the facility, and mismatches are where contractors get hurt: funding a five-year asset on a revolving line, or funding a recurring monthly gap with a fixed term loan that does not flex.
| Structure | What it funds | How it is generally sized | Main watch-out |
|---|---|---|---|
| Revolving line of credit | Payroll and material between billings | A percentage of eligible receivables, or a multiple of monthly deposits: varies by lender and file | Borrowing-base reporting and periodic clean-up requirements |
| Term loan | A known one-time need: a mobilization, a buyout, a hiring wave | Cash flow coverage against a fixed payment | Amortization does not flex when a month runs slow |
| Receivable-based facility | Specific invoices already billed and approved | An advance rate against eligible billings | Cost accumulates per invoice; customer notification may apply |
| Equipment finance | Machines and vehicles, which frees the line for labor | Useful life and collateral value | Financing short-lived assets over long terms |
| Supplier terms | Material | Trade history, volume and credit reporting | Losing early-pay discounts; concentration with a single vendor |
Availability, advance rates and structure vary by lender, by file and by the quality of your job-cost reporting. Nothing here is an offer or a prediction of terms.
Sizing the facility so it actually clears
Under-sizing is the quiet failure. A line covering 60% of the gap does not solve 60% of the problem; it delays the same crisis by a few weeks and consumes a personal guarantee doing it. Size against the peak, the gap is largest in the month you mobilize a new job while carrying the tail of the last one. Take your peak monthly direct cost over the last twenty-four months, multiply by your measured gap in months, subtract genuine supplier float, and treat that as the requirement. If it exceeds what your coverage supports, the answer is usually a combination, a line for the recurring cycle plus equipment financing that pulls fleet payments off the revolver: rather than one larger facility.
What to have ready before you ask
The contractor working-capital file
- Work-in-progress schedule showing contract value, cost to date, estimated cost to complete, billed to date and percentage complete for every open job.
- Accounts receivable aging with retainage broken out as its own column, not buried in current.
- Accounts payable aging, so the desk can see the supplier float you already use.
- Backlog schedule: signed contracts not yet started, with expected start dates.
- Two years of business tax returns and the most recent year-end financial statements.
- Six months of statements for every operating account.
- A schedule of every existing obligation with its monthly payment, including equipment notes and any advance with weekly or daily remittance.
- Your bonding letter or surety contact, if you are bonded.
What shrinks the gap without borrowing at all
- Bill on the cutoff, every month, without exception. A pay application submitted two days late usually costs a full cycle.
- Collect conditional lien waivers from subs and suppliers as invoices arrive, not while assembling the pay application.
- Walk percentages with the owner's representative before you submit rather than after they are disputed.
- Negotiate stored-material billing into the contract so long-lead deposits do not sit unbilled for months.
- Track notice and lien deadlines by job on a calendar; the deadlines vary by state and by your tier on the project.
- Push change orders to execution aggressively. Directed work you have not billed is the most expensive money in the business.
- Ask suppliers for terms that match your billing cycle instead of theirs. Volume is leverage, and most contractors never use it.
None of that is exotic. Together, though, a disciplined shop can often pull a week or two out of the cycle, and a week of cycle time on the illustrative business above is worth roughly $110,000 of permanently freed cash.
How do I know whether I have a cash flow problem or a profitability problem?
Compare your job margins to your bank balance trend. If jobs are closing at or above bid margin and the account still tightens as volume rises, it is a gap problem. If margins are eroding job to job, no facility fixes it, borrowing against a losing backlog only funds the loss faster. The work-in-progress schedule answers this in about an hour.
Will a lender advance against unbilled work in progress?
Generally not, or only at a heavily reduced rate. Unbilled work has not been approved by anyone outside your company, so it is not yet a receivable in an underwriter's view. The practical implication is that accelerating billing does more for availability than negotiating a higher advance rate, because it converts an ineligible asset into an eligible one.
Is a line of credit or a term loan better for a contractor?
It depends on whether the need repeats. A revolving line matches a recurring monthly cycle, because you draw when costs run and repay when the pay application funds. A term loan matches a discrete one-time need with a defined payback. Many contractors end up with both, and the mistake to avoid is carrying a permanent balance on a revolver, which signals the line is funding losses rather than timing.
How much does customer concentration hurt me?
It matters more in construction than in most industries, because losing one general contractor can take out a large share of your receivable base at once. Facilities secured by receivables commonly cap how much of the borrowing base any single account can represent, with the cap varying by lender. Diversifying your general-contractor relationships raises availability without raising your revenue.
Do prompt-payment laws actually help me get paid faster?
They can, and they are underused. Most states impose deadlines and interest on late payment for public work and, in many cases, private work as well, with the specifics varying considerably by state and contract tier. The leverage usually comes from citing the statute in writing before a relationship deteriorates, not from litigation afterward. Get local counsel to confirm what applies to your contracts.
Should I take a merchant advance to make a payroll?
It is the most expensive answer to a timing problem, and it compounds. Daily or weekly remittance products carry very high annualized debt service relative to the amount borrowed, which damages the coverage ratio a conventional lender will compute later, often enough to make an otherwise bankable contractor unbankable for a year or more. If the gap is structural, financing it structurally is cheaper even if it takes three weeks longer to arrange.
Where to start
Compute the gap this week. Pull your last twelve months of job cost and billing data, measure days to bill, days to approve and days to collect, and multiply the total by your daily direct-cost burn. That single number tells you how much capital your current volume requires and how much more your backlog is about to require.
Then decide which part of it you are going to fix operationally and which part you are going to finance. Billing discipline and waiver collection are free and fast. The residual is a real, permanent capital requirement, and it should be funded with a structure that matches its shape. If you want it sized by a desk rather than estimated, bring the work-in-progress schedule, the aging with retainage broken out and six months of statements, and have the file underwritten against your actual cycle.
