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 earn 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 comes out of operations in this trade, never out of pricing. It lives 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) takes the difference. This is the clearest overhead-recovery problem in the 48-trade dataset: the field isn't the source of the loss; 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 after taxes or 3.5 points better than your trade's industry 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 margin and overhead are before tax figures and net profit is an average after taxes, so the three are separate published values. The three CFOS targets tie out: gross margin target minus overhead target equals the net profit target.

HOW THE NET PROFIT FIGURES ARE BUILT

Gross margin and overhead come from figures CFMA, Jones Maresca and other sources publish by trade and size, and they are before tax figures. Net profit starts from gross margin less overhead and is then adjusted for taxes and a few other expenses, so it is stated after taxes. It is published as its own average and is not calculated from the other two on the page.

CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business. CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. Read a net profit figure here against CFMA's with that difference in mind. The bands above the $10M to $25M band are published at runoncfos.com as a modeled extension of the same curves. They have not been reconciled against the licensed CFMA Benchmarker, so read them as a model and not as a survey result.

The onboarding fee covers migrating your books back to the start of your last taxable year and getting you fully operational in 60 days. It's billed once, with your first invoice. It's the same for all three tiers. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

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. The onboarding fee is right here in the table.

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 and never in a report.

Your bookkeeper still does the books.

Executive

You stop touching the books.

Everything in Core, and we do the bookkeeping and the controllership as well. Your office stops answering coding questions and stops fixing a reconciliation that will not balance on the last day of the month.

We do the books. No payroll.

Strategic

Every job shows its margin while it is still open.

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 books, the job costing, and the software. No payroll.

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 reduced by 15 percent overhead, which makes overhead recovery, not field performance, the first place to look. Every net profit figure here is stated after taxes. CFMA reports net income before taxes, so a CFMA figure is higher than an after tax figure on the same business.

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 includes buildings and fleets: showroom, warehouse, delivery trucks, and estimating load make flooring overhead 15 percent at $1M to $5M, which is 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 has 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 goes up to $13,500 per month at the top published band. Onboarding takes 60 days.

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 do the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still open, 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.
