FIRE & LIFE SAFETY CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY FIRE PROTECTION CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Fire Protection margin is lost to three specific things: the pre-permit spend, the inspector's signature, and the blended-book blindfold. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Fire protection contractors at $1M to $5M net 7.5 percent on the SPM 48-trade dataset, matching electrical as the strongest floor in the group, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 11 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. $1,200 to $3,000 of hydraulic calculations and stamped drawings leave the account before a permit exists, and fabricated steel deposits follow. A schedule of values that starts billing at installation makes the contractor the project's design bank.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Pre-Permit Spend

$1,200 to $3,000 of hydraulic calculations and stamped drawings leave the account before a permit exists, and fabricated steel deposits follow. A schedule of values that starts billing at installation makes the contractor the project's design bank.

LEAK 02

The Inspector's Signature

Rough-in, pressure test, final, alarm tie-in: every gate is a billing milestone someone else controls, and the AHJ signs last. Retainage release waits on the one signature the contractor can least accelerate.

LEAK 03

The Blended-Book Blindfold

ITM recurs fast and small; contract work pays big and slow. One P&L over both hides which business funds which, and owners price both wrong until the split is on paper. (cfos-job-profitability-system) ---

WHAT CHANGES IN THE FIRST 60 DAYS.

Steel fabrication lead times and material procurement
The AHJ gauntlet (inspections as payment gates)

Industry figures are FireProtection contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out.

Range reflects the three tiers below. Which one you're in depends on how much of the work you want off your desk. No payroll. No hidden line items.

Core

You stop guessing.

You get the CFO work. Job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a meeting every month that ends in decisions rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Fire protection contractors at $1M to $5M net about 7.5 percent on the SPM 48-trade benchmark dataset, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 11 percent. The trade's margins are strong; the cash timing around engineering, fabrication, and inspections is where companies bleed. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
Because the spend curve front-loads. Engineering pays out before the permit, fabricated steel deposits before delivery, and fitter payroll runs weekly while billing milestones wait on inspections controlled by the AHJ. The receivable is real; the timing belongs to other people.
As its own schedule-of-values line, billed with the first pay application. Hydraulic calculations and stamped drawings cost $1,200 to $3,000 per commercial job; left out of the SOV, that money comes out of profit. Fabrication deposits and stored materials belong on the SOV the same way.
Yes, as separate divisions with separate P&Ls. NFPA 25 inspection work recurs annually at published market rates of $1,000 to $2,100 per system, pays quickly, and smooths cash; contract work pays slowly in large pieces. Blended books hide which side subsidizes the other and misprice both.
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.
Sulphur Prairie Management, operating as The Construction CFO, publishes the 48-trade benchmark dataset these numbers come from. SPM's deepest specialization is 24 core commercial trades, and SPM works with fire protection contractors who want the same financial system: onboarding, clean books, a maintained 13-week cash flow forecast, and monthly health reviews, with job costing simplified to what the business runs on. The full 48-trade benchmark reference exists so owners in every trade can measure against real numbers. ---
CFOS serves commercial fire protection subcontractors doing $1M to $12M. Pricing starts at $1,900 per month for companies under $1M and runs to $13,500 per month at the top published band. Onboarding takes 60 days.
