FRACTIONAL CFO FOR DRYWALL CONTRACTORS.

QUICK ANSWER

We manage the finance side for drywall subcontractors doing $1M to $12M. You get job costing aligned to the way you estimate, a 13 week cash flow forecast, monthly WIP, and a CFO in the room every month. Pricing starts at $1,900 per month.

Drywall is in the middle of the schedule with no float. So most of the CFO work is documenting what other people did to your hours. We keep a back-charge log that covers both sides, because this trade pays for damage and causes it. Charges of $500 and $3,000 go by uncounted job after job. We split hanger and finisher cost codes. They're different labor markets on different piece rates, sold under one unit price, and blended tracking doesn't show which half makes money. We also get the inspection standard into the contract. A finish judged with a flashlight down an unlit hallway is unpaid rework every time.

WHERE DRYWALL LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Flashlight Tax

When someone judges your finish under the wrong light, you do free rework. If the contract doesn't set the inspection standard (permanent lighting, perpendicular view), every punch walk is a negotiation you lose.

LEAK 02

The Damage Economy

Drywall pays back-charges and causes them, and most subs track neither side. Charges of $500 and $3,000 go by untracked, job after job. That's where the margin between 6 percent actual and the 10 percent CFOS target goes.

LEAK 03

The Middle Squeeze

Drywall gets every 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 you don't document and bill is margin you give to the schedule.

THE MATH

FROM 6% TO 10% NET.

At $1M to $5M, the average drywall sub earns 19% gross margin and spends 13% of revenue on overhead. What's left is 6% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 10% before taxes. That is the drywall average plus 3.5 points, and never below 10%. The book CONTROL's 12% is the rule of thumb across trades. It is not the industry average.

Two changes get you to the target. Overhead comes down 1 point to 12%, and gross margin comes up 3 points to 22%, so 22 minus 12 leaves 10. The gross margin points come from the three problems above, once you price them and bill for them. On a $3M year, every point is $30,000.

HOW SPM FIXES IT

WHAT WE CHANGE.

These are the drywall problems we put a number on first. Each one gets its own cost code, its own line on the schedule of values or its own line in the 13 week cash forecast, so you can read it in the monthly meeting while the job is still open.

Why aim for the target. An average is the middle of the pack: about half of companies do worse. And about 6 in 10 construction businesses close within 10 years (U.S. Bureau of Labor Statistics: about 40 percent of construction businesses opened in 2013 were still open in 2023). So the business in the middle is one of the ones that close. On those numbers, average is a business that closes within 10 years. That is why the CFOS target is a requirement.

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, and it moves with your revenue band. Your first month is prorated, and your monthly engagement starts on the first of the first full month.

Just want the setup? Onboarding only is the same onboarding work with no monthly service after it, one time, at the onboarding fee plus $2,000. Start a monthly engagement later and $2,000 counts toward it. It starts at $4,500, and the price for every band is on the pricing page.

The three tier columns are the whole price. Which one fits 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.

  • Online software only: QuickBooks, Sage, Viewpoint and similar. No VPN or hosted desktop.
  • Not in any tier: payroll, pay applications, collections on receivables.
  • Pricing valid through 2027.

What Core, Strategic and Platinum each include is on the pricing page.

Prevailing wage note: Drywall work often comes from public bids. On those jobs, certified payroll and wage classifications have to match the job cost record. ControlQore keeps the classification with the cost code, so the certified report and the job cost report come from the same data. Your office stops typing the same numbers twice every week.

COMMON QUESTIONS

FREQUENTLY ASKED.

Drywall contractors at $1M to $5M net 6 percent on average, rising to 13 percent by $25M to $50M; the CFOS net profit target is 10 percent before taxes at $1M to $5M, since the target is the trade average plus 3.5 points and never below 10. The difference usually comes from unpaid rework, untracked back-charges and schedule compression the unit price never priced. Every net profit figure here is gross margin minus overhead, stated before taxes, the same basis CFMA reports net income on.

See the full benchmarks for every revenue band on Run On CFOS.

Usually it needs the CFO work, and a full time CFO is more than it needs. At $5M to $10M, drywall subs average 9% net profit before taxes (Run On CFOS Trade Benchmark Reference), and the CFOS target is 12.5%. On $5M of revenue every point is $50,000, so that difference is worth $175,000 a year. A full time CFO costs $150,000 or more in salary alone. SPM's published price for $3.5M to $6.5M is $3,800 a month for Core to $8,300 for Platinum.

Inspection under permanent lighting, viewed from several feet back at a perpendicular angle. A flashlight raked down an unlit hallway is the wrong test. Put the inspection standard in the contract before the job starts. A sub who can't cite the standard pays for skim coats the spec never required.

Because labor pays out weekly through hang and finish, and the receivable comes in 60 to 90 days later. Then 5 to 10 percent retainage waits on the whole project's punch list, yours and everyone else's. At a 6 percent net margin before taxes, the retainage hold is bigger than the profit.

Log both sides on every job. For damage you cause, keep it small and check the GC's number. For damage done to your finished work, bill it, with photos and dates. Back-charges are contract adjustments, and no cash moves. So without a log, the adjustments only ever go one way.

About 13 percent of revenue at that size, trending to 10 percent by $25M to $50M. Drywall overhead is fairly lean. The trade's profit problem is in the gross margin line, so tracking rework and compression does more here than cutting overhead.

Tie the bid to a dated board price and a written spec. Then treat every substitution (abuse board, mold-resistant, Type X changes) as a change order with the material difference attached. Board at roughly $14.50 a sheet leaves no room to pay for spec changes without saying anything.

A bookkeeper records history. Rework cost codes, back-charge logs, hanger-versus-finisher tracking and compression documentation make up a control system, and that's CFO work. SPM does that CFO work for drywall contractors.

Three tiers, and which one you are in depends on how much of the work you want off your desk. On Core we build your plan every month and your team does the work: 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. On Strategic we build the plan, track it and adjust it every month: our team does the bookkeeping and the bank reconciliations, and the job costing and WIP software is set up and managed for you, on your own online software or ours. On Platinum we manage the money side for you every week: our team handles your bills and receivables the way an in-house controller would, and you approve every payment. We don't do payroll.

Sixty days. We migrate your books back to the start of your last taxable year and build your job costing structure from scratch, and on Strategic and Platinum we set up the job costing and WIP software too. You're fully up and working in two months. The onboarding fee is one time, the same for every tier, and set by your revenue band.

ControlQore is the job costing and WIP platform we use on the Strategic and Platinum tiers. It's built for contractors, costs less than the older tools, and has AI built in. We set it up and manage it, so you do not have to learn it. Core is the CFO work only, so it does not include the software.

A bookkeeper records what happened. We tell you what it means and what to do about it. We align job costing to your estimates, track WIP monthly, and hold a monthly meeting where you decide what to fix and who fixes it.

WHAT ELSE BREAKS IN DRYWALL

MORE PROBLEMS WE PUT A NUMBER ON.

Back-charge traffic in both directions

MEP conflict rework separate code

Drywall is in the middle of the damage economy. Other trades cut into finished board for rework and the repair gets back-charged to them; drywall crews gouge finished floors moving board and get back-charged themselves. Untracked, both directions leak margin invisibly.

Hanger and finisher economics (two crews, one price)

Tape float texture separate billing

Installing and finishing are different labor markets, different piece rates, and different production math, sold under one unit price. Blended tracking does not show which half of the operation makes money.

The middle-of-schedule squeeze

Floor by floor job costing

Drywall mobilizes after MEP rough-in and before finishes, which means it inherits every upstream delay with none of the float. Compressed hang-and-finish windows force overtime and stacked crews the unit price never covered.
