Fractional CFO vs Full-Time CFO
By Tom McCollum, ACA · Former KPMG Corporate Finance · Compass & Ledger
The short answer
A fractional CFO gives you senior financial leadership for a monthly fee, flexing with the work. A full-time CFO is a permanent executive. Most founder-led businesses preparing to raise, refinance or professionalise their finance function are better served by a fractional CFO first, then a full-time hire once the finance team and the business are big enough to need daily leadership.
Most founder-led businesses reach a point where the numbers need senior ownership: investors are asking harder questions, a lender wants covenant reporting, or the founder is spending evenings on spreadsheets. The question is whether that means a full-time hire yet.
How they compare
| Fractional CFO | Full-time CFO | |
|---|---|---|
| Cost | A monthly fee, scaled to the work | A full salary plus benefits, bonus and usually equity |
| Commitment | Monthly, flexes as the business changes | A permanent hire |
| Time to start | Days | Typically months to recruit |
| Experience | Senior and transaction-tested across many businesses | Depends on who you can attract at your stage |
| Equity | Usually none | Usually expected |
| Best for | Businesses preparing to raise, refinance or professionalise their finance function | Larger businesses needing a CFO in the building every day |
What a CFO actually does, and what you might need instead
Many businesses say they need a CFO when they need something narrower:
- Bookkeeping and accounts: recording transactions and closing the month. A bookkeeper or accountant.
- Controller: accurate monthly accounts, controls and reporting.
- CFO: strategy, fundraising, lender relationships, forecasting, board reporting and financial judgement.
A full-time CFO without a working controller function underneath often ends up doing the bookkeeping. A fractional model can cover the whole stack for one fee.
Signs a fractional CFO is right for now
- You're preparing to raise, refinance or buy a business.
- Your reporting isn't investor- or lender-grade yet.
- You need CFO-level judgement for a few days a month, not five days a week.
- You can't yet justify senior salary and equity for a permanent hire.
Signs you're ready to hire full-time
- A finance team large enough to need daily leadership.
- Complex operations: multiple entities, countries or business lines.
- Investors or lenders requiring a permanent CFO.
- Preparing for a major transaction such as a large raise, acquisition or sale, with a long runway of finance work behind it.
A common path
Many companies use a fractional CFO through a raise, build the finance function, then hire full-time once the scale justifies it. A good fractional CFO should make that handover easy: clean processes, documented models and a finance function the new hire can take over rather than rebuild. We can help recruit and hand over.
