WHY DRYWALL CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.
Drywall margin is lost to three specific things: the flashlight tax, the damage economy, and the middle squeeze. Drywall subcontractors at $1M to $5M run 19 percent gross and 5.5 percent net, against CFOS targets at $1M to $5M of 22 percent gross and 10 percent net. All three are measurable, and all three are invisible without job costing that reads against the estimate.
Drywall 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 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. Finish quality judged under the wrong light becomes free rework. Without contract language fixing the inspection standard (permanent lighting, perpendicular view), every punch walk is a negotiation the sub loses.
THE MATH BEHIND THE MISSING CASH.
The Flashlight Tax
Finish quality judged under the wrong light becomes free rework. Without contract language fixing the inspection standard (permanent lighting, perpendicular view), every punch walk is a negotiation the sub loses.
The Damage Economy
Drywall both absorbs and causes back-charges, and most subs track neither direction. Two untracked flows of $500 and $3,000 hits, job after job, is where the margin between 5.5 percent actual and the 10 percent CFOS target lives.
The Middle Squeeze
Drywall inherits upstream delay with no float and pays for it in overtime and stacked crews. At 19 percent gross margin, the thinnest in the interiors group besides framing, compression cost that's not documented and billed is margin donated to the schedule. (cfos-cash-flow-cycle-system) ---
WHAT CHANGES IN THE FIRST 60 DAYS.
| Metric | $1M to $5M | $5M to $10M | $10M to $25M |
|---|---|---|---|
| Gross margin, industry average | 19% | 21% | 22% |
| Gross margin, CFOS target | 22% | 23.5% | 24.5% |
| Net profit, industry average | 6% | 9% | 11% |
| Net profit, CFOS target | 10% | 12.5% | 14.5% |
| Overhead, industry average | 13% | 12% | 11% |
| Overhead, CFOS target | 12% | 11% | 10% |
Industry figures are Drywall 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.
Gross margin and overhead come from figures CFMA, Jones Maresca and other sources publish by trade and size. Net profit is derived 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.
