A fractional CFO is a senior finance leader who works for your company part time, on a monthly retainer or a defined project, instead of as a full-time hire. For a construction company the job is forward-looking: cash flow forecasting, a WIP schedule you can trust, surety and bank relationships, budgets, job profitability and big decisions like equipment and growth. It usually makes sense once the company has outgrown its bookkeeper's reporting but isn't big enough to justify a full-time CFO's salary.
There's a stage every growing contractor hits. The work is there, the revenue is up, and nobody can say with confidence how much cash the company will have in eight weeks. That's usually the moment the question of a CFO comes up.
Bookkeeper, controller, CPA, CFO: who does what
These roles get blurred, and the blur is part of why companies wait too long. Each one answers a different question.
| Role | The question they answer | Looks |
|---|---|---|
| Bookkeeper | Were the transactions recorded? | Backward, day to day |
| Controller | Are the books accurate, closed on time and properly controlled? | Backward, month to month |
| CPA firm | Are the statements and tax returns right, and do they meet the standard your surety or lender needs? | Backward, year to year |
| CFO | What happens next, and what should we do about it? | Forward |
A growing contractor can have a great bookkeeper and a great CPA and still have nobody whose job is the forward view. That's the gap a fractional CFO fills.
What a fractional CFO actually does for a contractor
Cash flow forecasting. A rolling 13-week cash forecast built from your billing schedule, payroll, retainage and payables, so a cash crunch shows up weeks ahead instead of on payday. Construction cash flow is lumpy enough that this alone often justifies the role.
A WIP schedule you can trust. Reviewing estimates to complete with project managers every month, catching fade early, and making sure the WIP schedule ties to the books before anyone outside the company reads it.
The surety and the bank. Preparing for renewals, explaining the numbers, negotiating limits and covenants. Underwriters respond to someone who can walk them through the financial statements and the plan behind them.
Budgets and job profitability. An annual budget and overhead plan, plus reporting that shows which job types, customers and crews actually make money.
Big decisions. Buying versus leasing equipment, whether to chase a larger project, opening a new market, adding a division, and the financing behind each.
Signs your company is ready for one
None of these alone means you need a CFO. Three or four together usually do.
Revenue has grown faster than your reporting. Cash surprises you, even in good months. Your bonding program is limiting the work you can bid, or your surety is asking questions nobody in the company can answer well. Your bank has covenants you're not sure you're meeting. Job reports come too late to change anything. You're running more than one entity. And the owner is still the person building the cash forecast at night.
Fractional versus a full-time CFO
A full-time CFO makes sense when the company is large and complex enough to need finance leadership every day. Before that point, a full-time hire means paying a senior salary for work that fills part of the week, and a senior person spending much of their time on tasks a controller could do.
A fractional CFO gives you the same level of thinking for the hours the company actually needs. A construction-specific one brings something else: they've already seen how WIP, retainage, bonding and job costing behave across many contractors, so they're not learning the industry on your time.
Many contractors use fractional as a bridge. The fractional CFO builds the forecasting, reporting and controls, and when the company eventually hires a full-time CFO, that person inherits a system instead of a mess.
How fractional CFO pricing usually works
Pricing depends on scope, not on a standard rate, so it's worth understanding the common structures before comparing quotes.
Monthly retainer. The most common model. A fixed monthly fee for a defined scope, such as the monthly close review, the cash forecast, a WIP review meeting and quarterly surety or bank reporting. Predictable for both sides.
Project-based. A fixed fee for a specific piece of work: preparing for a bonding increase, building a budget and forecasting model, cleaning up job costing, or getting ready for a sale or a succession.
Hourly or advisory. Occasional help on a specific decision. Useful as a start, but it rarely delivers the ongoing forecasting that's the main value of the role.
When comparing options, compare scope, not just price. Ask exactly what's included each month, who builds the forecast, and whether the person has worked with contractors' WIP schedules and sureties before.
What to ask before you hire one
Have you worked with construction companies at our size? Ask about percentage of completion, WIP and surety relationships specifically. What will we have after 90 days? A good answer names deliverables: a cash forecast, a WIP review process, a reporting package. How do you work with our CPA and our bookkeeper? The roles should fit together, not overlap. Who talks to our surety and our bank? If the answer is "you do," that's a gap.
