WHY FLOORING CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Flooring margin is lost to three specific things: the moisture gate, the overhead engine, and the material float. Flooring subcontractors at $1M to $5M run 24 percent gross and 5 percent net, against CFOS targets at $1M to $5M of 23 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Flooring contractors at $1M to $5M net 5 percent, rising to 7.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 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. The slab's readiness, not the GC's schedule, governs the install date, and a floor laid on a wet slab is a six-figure failure with the installer's name on it. ASTM-documented testing, a written sign-off protocol, and testing billed as a line item are the trade's real insurance policy; a $1.3 million settlement over one Best Buy floor proves the stakes.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Moisture Gate

The slab's readiness, not the GC's schedule, governs the install date, and a floor laid on a wet slab is a six-figure failure with the installer's name on it. ASTM-documented testing, a written sign-off protocol, and testing billed as a line item are the trade's real insurance policy; a $1.3 million settlement over one Best Buy floor proves the stakes.

LEAK 02

The Overhead Engine

Flooring earns a 24 percent gross margin and keeps 5 percent, because 15 percent overhead (showroom, warehouse, fleet, estimating) eats the difference. This is the clearest overhead-recovery problem in the 48-trade dataset: the field isn't the leak; the building is.

LEAK 03

The Material Float

Deposits out at order, freight and acclimation in the middle, billing at install: the sub banks a five-figure material position on every specialty job unless stored-materials and deposit terms are negotiated up front. (cfos-working-capital-system) ---

Industry figures are Flooring 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.

Flooring contractors at $1M to $5M net 5 percent on average, rising to 7.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. Flooring's paradox is a strong 24 percent gross margin eaten by 15 percent overhead, which makes overhead recovery, not field performance, the first place to look. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
It turns on testing and documentation. A sub who tested per ASTM, reported the readings, and got a written directive or sign-off before installing shifts the liability up; a sub who installed on a known-wet slab without that paper owns the failure, and one such failure settled for $1.3 million with the CGL carrier off the hook. Test, document, and never install past a failed reading without a signed directive.
Because curing and drying are different processes. Concrete reaches design strength at 28 days and can still hold moisture far above flooring tolerance, especially slabs without vapor retarders. The install date belongs to the moisture readings, not the pour date or the GC's schedule.
As its own line item, with documented ASTM-standard readings attached to the pay application. Testing that lives inside the unit price disappears; testing on its own line gets done, gets paid, and builds the paper trail that decides liability if a floor ever fails.
Because the trade's business model carries buildings and fleets: showroom, warehouse, delivery trucks, and estimating load run flooring overhead to 15 percent at $1M to $5M, which sits at the top of the 8 to 15 percent total indirect cost range Jones Maresca and Company's 2025 Performance Benchmarks publish for construction as a whole and well above the 11.8 percent SG&A CFMA reports across all respondents. Those are whole-industry averages rather than a flooring target, and /construction-overhead-rates-by-trade carries the flooring rate by revenue band. Overhead recovery rates in every bid, reviewed quarterly, are how the strong gross margin reaches the bottom line.
Specialty material is ordered on deposits, ships on the mill's timeline, and acclimates on site before install, so the sub finances a five-figure material position through the middle of every job. Negotiate deposit reimbursement and stored-materials billing into the contract; the default terms make the flooring sub the bank.
A bookkeeper records history. Moisture-testing protocols, overhead recovery rates, stored-materials terms, and retainage tracking are a control system, which is CFO work. SPM operates that financial control function for flooring contractors. ---
CFOS serves commercial flooring 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.
