ONE PROBLEM, IN DETAIL

AHJ RETAINAGE DELAY: THE AHJ GAUNTLET

QUICK ANSWER

Sprinkler systems inspect multiple times: rough-in, hydrostatic pressure test, final, and often a separate alarm tie-in. Each gate can hold a billing milestone hostage, and commercial inspection coordination alone consumes 8 to 16 labor hours per project. The site's existing.

WHAT THIS TRADE SHOULD EARN

THE NUMBER TO MEASURE IT AGAINST.

Fire Protection contractors run about % net profit at $1M to $5M, rising to roughly 11% 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 25%, against a CFOS target of 11%.

COMMON QUESTIONS

FREQUENTLY ASKED.

Every inspection is a payment gate: rough-in, hydrostatic test, final, alarm tie-in. Failed or delayed inspections push billing milestones and the retainage release, and the AHJ's final signature is the one date no contractor controls. Budget the coordination hours (8 to 16 per commercial job) and calendar every gate.
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.
