CONCRETE & MASONRY CLUSTER · CFOS TRADE OPERATING SYSTEM

WHY MASONRY CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.

QUICK ANSWER

Masonry margin is lost to three specific things: the access tax, the lay-rate spread, and the material bleed. Masonry subcontractors at $1M to $5M run 21 percent gross and 5.5 percent net, against CFOS targets at $1M to $5M of 23.5 percent gross and 10.5 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.

Masonry contractors at $1M to $5M net 5.5 percent, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10.5 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. Scaffold, fall protection, and lifts add up to 40 percent to labor cost on elevated work, and scaffold premiums run 50 to 100 percent of labor for stages above 10 feet. Access is a second job inside every job; unpriced, it's a donation.

THE THREE BIG LEAKS

THE MATH BEHIND THE MISSING CASH.

LEAK 01

The Access Tax

Scaffold, fall protection, and lifts add up to 40 percent to labor cost on elevated work, and scaffold premiums run 50 to 100 percent of labor for stages above 10 feet. Access is a second job inside every job; unpriced, it's a donation.

LEAK 02

The Lay-Rate Spread

Crews range from 200 to 1,000 bricks a day depending on complexity. Bidding the fast day and building the slow day converts labor variance straight into lost margin, and labor is the biggest line in the trade.

LEAK 03

The Material Bleed

Standard waste runs 8 to 10 percent and complex work reaches 15. An estimate using 5 percent waste on a 12 percent job leaks the difference from every pallet, and nobody sees it without variance tracking. (cfos-job-profitability-system) ---

Industry figures are Masonry 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.

HOW THE NET PROFIT FIGURES ARE BUILT

Gross margin and overhead come from CFMA, Jones Maresca and SPM's own trade data, because those are the figures those sources report by trade and size. Net profit is calculated from them as gross margin minus overhead, so the three rows tie. That makes it an operating profit figure: what is left before interest, other income and expense, and the tax planning choices owners make, such as bonuses, depreciation methods and retirement contributions.

Surveys report net income before taxes after those items, so a reported net can run below the figure here. At the typical contractor the difference is small: CFMA's 2025 medians are 7.1 percent before interest and taxes and 6.7 percent net income before taxes. It grows with size. Against the separate measured net profit dataset, the calculated net runs 0.8 points higher at $1M to $5M, 2.2 points at $5M to $10M and 3.5 points at $10M to $25M, because the gross margin and overhead rows change faster with size than reported net profit does. 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, and the calculated net there runs well above survey medians, 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 run the bookkeeping and the controllership as well. Your office stops answering coding questions and stops chasing a reconciliation on the last day of the month.

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

COMMON QUESTIONS

FREQUENTLY ASKED.

Masonry contractors at $1M to $5M net 5.5 percent on average, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10.5 percent. The gap to target in this trade almost always sits in three labor-side leaks: unpriced scaffold, lay-rate variance, and material waste above the estimate. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
8 to 10 percent on standard work; complex patterns, cuts, and repair work run up to 15 percent. Estimate below the real number and the material line eats margin on every pallet. Track waste variance per job so the estimating factor comes from your own history, not a rule of thumb.
For stages of work above 10 feet, scaffold premiums run 50 to 100 percent of the labor cost for that work, and access costs overall (scaffold, fall protection, lifts) can add up to 40 percent to total labor. Price access as its own line; it's a second job inside the job.
200 to 1,000 depending on complexity: ornate fireplace work sits at the low end, simple walls at the high end, and experienced masons average 400 to 600 on standard work. The number that protects margin is your own crews' tracked rate by wall type, compared to the estimate weekly.
Because labor pays out every Friday and the receivable lands 60 to 90 days later, minus 5 to 10 percent retainage. Add a cold-weather month with heated enclosures and slow cure times and the cash gap widens while the income statement still looks fine.
About 13 percent of revenue at that size, trending toward 11 percent as revenue grows. Jones Maresca and Company's 2025 Performance Benchmarks put total indirect cost at 8 to 15 percent of revenue for construction as a whole, and CFMA's 2024 Construction Financial Benchmarker reports SG&A at 11.8 percent across all respondents; masonry at your revenue runs differently from either whole-industry average, which /construction-overhead-rates-by-trade sets out by band. Masonry overhead hides in scaffold inventory, mixers, saws, and trucks; the owned-versus-rental scaffold decision alone moves the number.
Give winter work its own cost codes (enclosures, heat, admixtures, thaw time) and either bid a winter premium or document the delay for compensation. The mortar clock doesn't negotiate; the only choice is whether the cost is priced, claimed, or eaten.
A bookkeeper records history. Waste variance tracking, lay-rate job costing, scaffold allocation, and seasonal cash reserves are a control system, which is CFO work. SPM operates that financial control function for masonry contractors. ---
CFOS serves commercial masonry 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.
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.
