TL;DR: Most fractional CFO firms won't serve contractors under $10M. SPM was built specifically for the $1M–$10M commercial subcontractor — civil, concrete, electrical, erosion control, and adjacent trades. 60-day onboarding. ControlQore job costing. Starting at $1,900/month. The problems at $1M–$10M are identical to larger contractors — uncollected AR, wrong overhead rate, no job costing — just at a scale where a generalist CFO is overkill and a bookkeeper is not enough.

Fractional CFO for Subs
Under $10 Million.

Most fractional CFO firms set minimums at $10M–$15M revenue. SPM was built specifically for the $1M–$10M subcontractor who needs more than a bookkeeper but cannot justify a full-time CFO.

About SPM

Who We Are and Who We Serve

SPM serves commercial subcontractors doing $1M–$10M in revenue — the exact band most fractional CFO firms skip. The financial problems at $3M are identical to the problems at $8M: uncollected AR, overhead miscalculated in bids, no job costing. The difference is scale, not structure.

Why $1M–$10M Is Our Target

Large fractional CFO firms set revenue minimums because smaller contractors are not profitable for them. SPM was priced specifically for this band — starting at $1,900/month for Core Financial. The fee scales with revenue so a $2M contractor pays proportionally the same as a $6M contractor.

Operations-First

Josh Luebker is a former master electrician and commercial PM — not a CPA. SPM starts with what is happening operationally and builds the financial system around it. For a $3M civil sub, that means job costing aligned to how you estimate, not how an accountant categorizes expenses.

60-Day Full Onboarding

Most fractional CFO firms take 6–9 months to fully set up a client. SPM gets books migrated, ControlQore configured, job costing built, and WIP reporting live in 60 days.

CFO vs. Bookkeeper

At $1M–$10M, a bookkeeper records what happened. A CFO tells you what it means and what to do. The difference is the system — job costing, WIP, cash flow forecasting, overhead rate calculation. SPM builds and runs that system every month.

FAQ

Frequently Asked Questions

Is a fractional CFO worth it for a subcontractor under $5M?
Yes — if the business has job costing complexity and pay app billing. At $2M–$5M the financial problems are identical to larger contractors: uncollected AR, wrong overhead rate, no job-level visibility. SPM Core Financial starting at $1,900/month is designed for this band. AR collected in the first 30 days typically covers the first 3–6 months of fees.
What is the minimum revenue to work with SPM?
SPM works with contractors starting at $1M in annual revenue. Below $1M the business typically does not have enough job complexity to justify full job costing setup. At $1M+ the pay app structure, WIP reporting, and overhead rate calculation become meaningful enough to drive real outcomes.
What does fractional CFO cost for a $3M subcontractor?
At $1M–$3M revenue, SPM Core Financial is $2,600/month and Executive Financial is $3,600/month. Core Financial includes ControlQore setup, job costing structure, bank reconciliations, and bookkeeping. Executive Financial adds monthly CFO advisory, controllership, and strategic accountability.
How long does it take to see results with SPM?
Most clients see the first measurable result — AR collected — within the first 30 days. Structural fixes take 60 days to fully implement. By month three, most clients have a functioning financial system and job-level profitability visibility for the first time.
Does SPM handle payroll?
No. SPM does not handle payroll. Clients manage payroll through their existing payroll provider. SPM focuses on job costing, WIP reporting, cash flow management, overhead rate, and CFO advisory.
