FRACTIONAL CFO FOR SIDING CONTRACTORS.

QUICK ANSWER

We run the finance function for siding 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.

Siding is the last trade to touch the wall, which means it explains first when water turns up years later. So we get scope boundaries written down before the first course goes on, covering whose housewrap, whose window flashing, and whose integration at every penetration, and we photograph cover-up conditions as a standing habit. We split the four product lines in the cost codes, because vinyl, fiber cement, engineered wood, and metal panel run different material costs, crew skills, and fastening specs, and manufacturer requirements on clearance, gapping, and fasteners are warranty conditions rather than suggestions. Then we track production by detail class, since field wall sets the pace the bid remembers and corners, trim, and transitions set the pace the job runs.

WHERE SIDING LOSES MONEY

THE THREE THINGS THAT DRAIN THE CASH.

LEAK 01

The Seam That Leaks Later

WRB, flashing, and integration scope seams surface as leak claims years after cover-up, and the last trade to touch the wall explains first. Written boundaries and cover-up photos are the cladding contractor's decade-long testimony.

LEAK 02

The Warranty Gate

Manufacturer installation specs are warranty conditions: clearances, gapping, and fastener schedules installed outside the book kill the product warranty and leave the installer holding the tail. Spec-compliance documentation is the QC that pays.

LEAK 03

The Field-Wall Illusion

Squares of field wall set the pace the bid remembers; corners, trim, and transitions set the pace the job actually runs. Production tracked by detail class is the difference between a 5.5 percent floor and the levers above it. (cfos-job-profitability-system) ---

HOW SPM FIXES IT

WHAT WE CHANGE.

The WRB seam (whose water barrier is it?)
Material mix economics (four products, four cost worlds)
Detail density (the linear-foot tax, cladding verse)
Weather-exposed production and the swing-stage question
The thin floor (why siding sits at the batch's bottom)

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.

Siding contractors at $1M to $5M net about 5.5 percent on the SPM 48-trade benchmark dataset, among the thinnest floors of the 48, rising to 8 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The levers are product-line splits, detail-class pricing, and the documentation discipline that keeps leak claims where they belong. 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.
