FRACTIONAL CFO FOR ACOUSTIC CEILING CONTRACTORS.

QUICK ANSWER

We run the finance function for acoustic ceiling subcontractors doing $1M to $12M: 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, and every re-entry after a room is gridded is either 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 have no business sharing one margin history. Then we track the retainage hold as its own receivable class, since a 10 percent hold rivals the entire 6 percent net before taxes that a typical year in this trade produces.

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, and every "one more fix" reopens a finished room on the ceiling contractor's dime. Room-readiness tracking and billed re-entries convert the trade's position from hostage to gatekeeper.

LEAK 02

The Two Ceilings

Lay-in grid is production; specialty systems are engineered millwork overhead. One blended book misprices both, and specialty's submittal-and-lead-time cash curve needs its own plan.

LEAK 03

The Visible Finish

The ceiling is the punch walk's easiest target and the retainage line's last release. Tile-swap punch labor priced in, and retainage tracked as its own receivable class, keep the finish line from eating the margin. (cfos-working-capital-system) ---

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.

Acoustic ceiling contractors at $1M to $5M net about 6 percent on the SPM 48-trade benchmark dataset, rising to 8.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 11.5 percent. The leaks are unbilled remobilizations, blended lay-in/specialty pricing, and last-trade retainage drag. Every net profit figure here is stated before taxes, the same basis CFMA reports on, so the two are directly comparable.
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.
