WHY YOU'RE SHORT

CONCRETE JOBS LOOK PROFITABLE. THE ACCOUNT IS STILL EMPTY.

QUICK ANSWER

Concrete subcontractors have no cash left for reasons specific to how the work is built and billed, on jobs that are making money. The three that cost the most in this trade are below, taken from concrete contractor research. Most are at 75 to 90 days from finishing work to holding the money, and 45 days is achievable.

Cash and profit are measured on different clocks. Your profit and loss records revenue when you invoice and costs when you incur them, while the bank account only knows what cleared. Labour goes out weekly and collects 45 to 90 days later, minus retention. That distance is what a growing, profitable concrete company funds out of pocket, and it widens as you grow. The specific things that widen it in this trade are what the rest of this page is about.

WHERE THE CASH GOES IN CONCRETE

WHERE IT LEAKS OUT.

01 · AR and the factoring trap

Concrete's receivables age like every sub's, and the desperate version of the fix (invoice factoring, merchant cash advances) converts a timing problem into a margin hemorrhage. The site already tells the counter-story with real numbers: a $4.9M concrete contractor went from $161K to $1.1M net once the control system replaced the debt spiral.

THE THREE THAT DECIDE THE YEAR

WHAT MOVES MARGIN IN THIS TRADE.

LEAK 01

The Pour-Day Cascade

Trucks on the clock, finishers waiting, weekend premiums of $50 to $300 per load, and a cold-joint spec risk if sequencing falls behind. Pour day is where the estimate meets physics, and untracked standby and premium cost is margin poured into the slab.

LEAK 02

The 28-Day Gate

Strength comes on the concrete's schedule, not the billing schedule, and a failed break leads to coring, repour risk, and a delayed milestone. The test report is a payment gate; treat it like one with a reserve and a protocol.

LEAK 03

The Factoring Spiral

Aged AR sent through factoring or an MCA trades a timing problem for a permanent margin tax. A $4.9M concrete contractor netted $161K inside that cycle and $1.1M net outside it; the difference was the control system, in the same market as the year before. (cfos-cash-control-system) ---

THE NUMBER TO MANAGE

DAYS SALES OUTSTANDING.

Ninety days is weak, 45 is the target, 30 is strong. Nothing else moves cash faster.

PositionDaysWhat it means
Weak90 daysRoughly three months of work funded out of your own pocket.
Target45 daysAchievable on the days you control: submission timing, complete documentation, follow up in week two.
Strong30 daysRequires discipline every month, and it's the cheapest capital available to you.

Moving from 90 days to 45 frees roughly annual revenue divided by 365, times 45 days. At $4M that's about $493,000. At $8M it's about $986,000. That money doesn't come from a bank and it costs no interest, which is why we work the cycle before discussing financing anything.

WHERE YOU SHOULD BE

CONCRETE BENCHMARKS.

Concrete subcontractors at $1M to $5M net 7 percent, against a CFOS target of 10.5 percent, set at 10 percent before taxes or 3.5 points better than your trade's industry average at your revenue, whichever is higher. The working capital target is 13 percent of annual revenue, and the monthly close should finish by day 10 so the numbers can still change a decision.

COMMON QUESTIONS

FREQUENTLY ASKED.

Because the jobs earn before the money comes in. Labour and material go out on a weekly cycle and collect 45 to 90 days later, with 5 to 10 percent held as retention behind that. In concrete specifically that distance is widened by ar and the factoring trap. None of that reads as a loss on any single job, which is why it goes unaddressed.

Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Strategic is where every job shows its margin while it is still open: a bookkeeper we choose does the books and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. Platinum is where you approve and the money side gets handled: a controller we choose handles your bills and receivables the way an in-house controller would, and you approve every payment. No payroll. No scope gaps.
