FRACTIONAL CFO
VS. FULL-TIME CFO.
FOR TRADE CONTRACTORS.
For trade contractors doing $1M–$12M, a construction-specific fractional CFO almost always wins over a full-time hire. A full-time CFO costs $120,000–$200,000 per year and most have never seen a WIP schedule or a pay-when-paid clause. A fractional CFO who specializes in construction costs $24,000–$48,000 per year, is operational in 60 days, and already knows what is broken before they see your first number. The full-time hire makes sense above $10M where the volume justifies it.
This is not about which title sounds more impressive. It is about what your business actually needs right now — and what each option can and cannot deliver for a commercial subcontractor doing $1M to $12M.
| FACTOR | FRACTIONAL CFO | FULL-TIME CFO |
|---|---|---|
| Annual cost | $24,000–$48,000 (fractional) | $120,000–$200,000+ (salary + benefits) |
| Construction expertise | Specialists in construction — already know WIP, job costing, pay-when-paid | Rare. Most CFOs come from tech, finance, or manufacturing. Learning curve is costly. |
| Job costing setup | Installs and manages the full system | May or may not understand construction job costing structure |
| Monthly cadence | Runs it — cost to complete, CEO report, cash forecast | Builds it — if they know how |
| Onboarding time | 60 days to fully operational | 3–6 months minimum before contributing at full capacity |
| Bandwidth | Focused on your financials with a team behind them | One person — no backup when sick, on vacation, or burned out |
| When you outgrow them | Clear handoff path — they prepare you for a full-time hire | Already there — but may be over-resourced for your revenue level |
| Best revenue range | $500K–$15M | $10M+ where full-time CFO scope is justified by volume |
| Right for | Contractors who need the system installed and run NOW | Contractors doing $10M+ who have outgrown the fractional model |
Under $10M: fractional. Over $10M: evaluate. The construction expertise gap is what most contractors miss.
The biggest mistake trade contractors make when hiring a full-time CFO is assuming any CFO can handle construction. WIP reporting, job costing structure, pay-when-paid cash flow, retainage tracking, and bonding capacity management are construction-specific. Most CFOs learn these on the job — on your dime.
A construction-specific fractional CFO already knows your trade, already knows what is broken in a $3M subcontractor, and is operational in 60 days. By the time a full-time hire is up to speed on construction accounting, you have paid 6 months of salary and benefits.
The exception: If you are doing $10M+ and need someone embedded full-time who attends every GC meeting, handles every lender relationship, and leads a finance team — a full-time CFO starts to make sense. A good fractional CFO at that stage will tell you when you have outgrown them and help you make the transition.
- You are doing $500K–$10M in commercial work and need the financial system installed now
- You cannot afford to wait 3–6 months for a full-time hire to get up to speed on construction
- You need job costing, overhead calculation, estimating alignment, and the monthly cadence — not just financial reporting
- You want construction-specific expertise, not a generic CFO learning your trade on your engagement
- You want to spend 5 hours a month on financials — not manage a full-time employee
- You are doing $10M+ and the volume of decisions requires daily financial leadership
- You have a finance team that needs a full-time leader
- You are pursuing bonding above $10M single project and need daily surety relationship management
- You are preparing for a sale or acquisition and need full-time financial preparation
- Your fractional CFO has told you that you have outgrown the model
The Construction CFO at constructioncfo.net is the construction-specific fractional CFO service built on the CONTROL system. Two tiers — Core Financial from $1,900/month and Executive Financial from $2,900/month. 60-day onboarding. 24 trades. No payroll. No scope gaps.
For most commercial subcontractors, a full-time CFO becomes justifiable at $10M–$15M in revenue — where the volume of decisions, the complexity of WIP, and the bonding requirements demand dedicated full-time financial leadership. Below that, a fractional CFO provides more construction-specific expertise at a fraction of the cost.
A construction-specific fractional CFO installs the financial operating system — job costing structure, overhead calculation, estimating alignment, software setup, PM standards — and then runs the monthly cadence: cost to complete, CEO report, 13-week cash forecast, and monthly strategic meeting. They are not advising. They are running the function.
Construction-specific fractional CFO services for trade contractors typically run $1,900 to $2,900 per month depending on revenue and scope. That compares to $120,000 to $200,000 per year for a full-time CFO with benefits — plus the risk that most CFOs do not understand construction accounting.
Yes — a construction-specific fractional CFO should handle WIP reporting, surety relationship management, and bonding capacity optimization as core deliverables. This is one of the areas where construction-specific expertise matters most. A generic CFO often does not know what a WIP schedule is or how sureties evaluate it.
