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.

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Concrete contractors have about 7% net profit at $1M to $5M, rising to roughly 9% at $5M to $10M. The CFOS net profit target is 10.5% before taxes at $1M to $5M, the trade's average plus 3.5 points, never below 10%. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.

Gross margin over the same bands is 21% to 22%,against CFOS targets of 23.5% and 24.5%.

COMMON QUESTIONS

FREQUENTLY ASKED.

It converts a timing problem into a permanent margin tax, and it compounds. The verified alternative on this site: a $4.9M concrete contractor exited the factoring-and-debt spiral and moved from $161K to $1.1M net through AR discipline, billing velocity, and a 13-week cash forecast instead.

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.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. Fully operational in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.
