What Is a Fractional CFO — and When Do You Need One?
The difference between a bookkeeper, a controller and a CFO, and the revenue stage where fractional CFO leadership pays for itself.
As businesses scale, the finance function splits into three roles that are easy to conflate. Knowing which you need — and when — keeps you from over- or under-buying.
Bookkeeper vs controller vs CFO
- Bookkeeper — records and reconciles the past accurately.
- Controller — owns the close, controls and accrual-grade reporting (present).
- CFO — uses the numbers to shape strategy, cash and fundraising (future).
When fractional CFO leadership pays off
Most companies feel the need between $1M and $3M in revenue — enough complexity to need forecasting and unit-economics discipline, not enough to justify a full-time hire. A fractional CFO gives you that leadership for a fraction of the salary.
