FRACTIONAL CFO FOR ACOUSTIC CEILING CONTRACTORS.

QUICK ANSWER

We manage the finance side for acoustic ceiling 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.

Most of what a CFO does in this trade is turn other trades' schedules into your billing. The ceiling closes last in every room, so the above-ceiling sign-off is your real notice to proceed. Every re-entry after a room is gridded is a billed change or free labor. We split lay-in grid from specialty engineered systems in the cost codes, because production work and submittal work shouldn't share one margin history. We also track the retainage hold as its own receivable class. A 10 percent hold rivals the whole 8 percent net before taxes this trade makes in a typical year.

WHERE ACOUSTIC CEILING LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Plenum Hostage

Five trades finish above the grid before tile drops. Every "one more fix" reopens a finished room on your dime. Track which rooms are ready, bill the re-entries, and you go from hostage to gatekeeper.

LEAK 02

The Two Ceilings

Lay-in grid is production work. Specialty systems are engineered work with millwork overhead. One blended book misprices both. Specialty work has submittals and long lead times, so its cash needs its own plan.

LEAK 03

The Visible Finish

The ceiling is the easiest target on the punch walk and the last retainage to be released. Price tile-swap punch labor into the bid and track retainage as its own receivable class. Then the finish line doesn't cut your margin.

THE MATH

FROM 8% TO 11.5% NET.

At $1M to $5M, the average acoustic ceiling sub earns 21% gross margin and spends 13% of revenue on overhead. What's left is 8% net profit before taxes (Run On CFOS Trade Benchmark Reference). The CFOS target is 11.5% before taxes. That is the acoustic ceiling 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 2.5 points to 23.5%, so 23.5 minus 12 leaves 11.5. 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 acoustic ceiling 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.

COMMON QUESTIONS

FREQUENTLY ASKED.

Acoustic ceiling contractors at $1M to $5M net about 8 percent on the SPM 48-trade benchmark dataset, rising to 14 percent by $25M to $50M; the CFOS net profit target is 11.5 percent before taxes at $1M to $5M, the trade average plus 3.5 points. The money goes to unbilled remobilizations, one price for lay-in and specialty work, and late retainage as the last trade. 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, acoustic ceiling subs average 10% net profit before taxes (Run On CFOS Trade Benchmark Reference), and the CFOS target is 13.5%. 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.

Because everything is above the grid. Duct, pipe, sprinkler, tray and conduit all finish and pass inspection before tile drops. So your crew mobilizes on five other trades' completion dates, then reopens rooms for their late fixes. Track above-ceiling sign-offs by room, treat each one as your notice to proceed, and bill re-entries with the cause written down.

No. Standard grid is production work. Wood, metal, felt and cloud systems are engineered installations. They have submittal cycles, long-lead custom material and millwork-grade layout. Manage them as separate divisions, each with its own cost history and its own cash plan.

Put the waste and attic-stock math in the takeoff. That covers spec'd attic stock, dye-lot matching on large orders, and the damage you get when the job's most fragile finish is stored on an active site. Log damage by cause. Tile broken by another trade's lift is a back-charge to that trade.

Hard. You finish near last, so release waits on the whole project's punch. At an 8 percent floor, the hold rivals the profit. Track retainage as its own receivable class, price tile-swap punch labor into the bid, and put the release conditions on the calendar from day one.

Sulphur Prairie Management, operating as SPM The Construction CFO, publishes the 48-trade benchmark dataset these numbers come from. SPM's deepest specialization is 24 core commercial trades, and SPM works with acoustic ceiling contractors who want the same financial system: onboarding, clean books, a maintained 13-week cash flow forecast, and monthly health reviews, with job costing simplified to what the business needs. The full 48-trade benchmark reference exists so owners in every trade can measure against real numbers.

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.

Our guarantee holds when you come to every meeting, do the process and keep a strong pipeline of work. We can fix how your work pays. We can't fix having no work.
