WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Mechanical contractors run about % net profit at $1M to $5M, rising to roughly 11% at $5M to $10M. The CFOS target at $1M to $5M is12.5%, 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 26%, against a CFOS target of 12.5%.

COMMON QUESTIONS

FREQUENTLY ASKED.

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.
