FRACTIONAL CFO FOR LOW VOLTAGE / AV CONTRACTORS.

QUICK ANSWER

We run the finance function for low voltage / av 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.

Low voltage sells by the drop, and the trade's whole margin problem is that nobody agrees what a drop includes. We define it in writing before the contract signs, meaning pull plus terminations plus testing plus labeling plus documentation, and we log base counts so added drops become change orders instead of favors. Billing then rides the test reports and the label schedule, because cable pulled and not certified is inventory sitting in a ceiling rather than revenue, and a subcontractor already waits 56 days on average after submitting a pay application. On the AV side we write commissioning protocols with defined pass conditions, since acceptance without criteria means the job closes when the client's taste is satisfied and that day never appears on your calendar.

WHERE LOW VOLTAGE / AV LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Undefined Drop

The trade sells by the drop, and an undefined drop (pull only, or pull-terminate-test-label-document?) makes every unit price a future argument. Define the unit, log the count, and added drops become change orders instead of favors.

LEAK 02

The Untested Ceiling

Cable that's pulled but not certified is inventory, not revenue: billing rides the fluke reports and the label schedule. Documentation-complete is the collection strategy, per drop, daily.

LEAK 03

The Subjective Punch

AV acceptance without written criteria means the job closes when the client's taste is satisfied, which is never on the contractor's calendar. Commissioning protocols with defined pass conditions are how integration projects end on paper. (cfos-cash-flow-cycle-system) ---

HOW SPM FIXES IT

WHAT WE CHANGE.

Drops are the unit, and everyone counts them differently
Certification-gated payment (test results are the closeout)
The integration tail (AV projects that never close)
Project vs service/managed (the family's divisional rule, fourth verse)
Licensing patchwork and prevailing-wage classification

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.

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 rather than a report.

Your bookkeeper keeps doing the books.

Executive

You stop touching the books.

Everything in Core, and we run the bookkeeping and the controllership as well. Nobody in your office is answering coding questions or chasing a reconciliation at month end.

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 job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Low-voltage and AV contractors at $1M to $5M net about 6.5 percent on the SPM 48-trade benchmark dataset, rising to 9 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The trade's leaks are undefined drop scopes, untested-therefore-unbilled production, and integration punch lists without acceptance criteria. 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.
