ONE PROBLEM, IN DETAIL

DAVIS BACON JOB COSTING: PREVAILING WAGE AND CERTIFIED PAYROLL

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Electrical contractors run about % net profit at $1M to $5M, rising to roughly 12% at $5M to $10M. The CFOS target at $1M to $5M is11%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. 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 runs % to 27%, against a CFOS target of 11%.

COMMON QUESTIONS

FREQUENTLY ASKED.

Build fully burdened rates per classification before the bid, not after the audit. Fringe handling, classification mapping, and weekly certified payroll are systems problems; misclassification claws margin back retroactively. Software handles the filing; the rate discipline protects the margin.
Electrical contractors at $1M to $5M net 7.5 percent on average, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 11 percent. Electrical carries the highest gross margins of the site trades, which means the gap to target usually sits in overhead and AR, not in the field. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because the job structure buries cash in the middle. Wire and labor go in at rough-in, trim-out billing lands months later, retainage holds 5 to 10 percent, and switchgear deposits leave the account years before the gear bills. Profit shows on the statement while the cash sits in walls, holdbacks, and OEM production slots.
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. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
Sixty days. We migrate your books back to the start of your last taxable year, set up ControlQore, and build your job costing structure from scratch. Fully operational in two months.
