What Does a Fractional CFO Actually Do?
A fractional CFO provides senior-level financial leadership on a part-time or flexible basis.
They focus on strategy, forecasting, and decision support rather than day-to-day bookkeeping.
A fractional CFO helps leaders understand where the business is going, not just where it’s been.

Bookkeepers and accountants focus on accuracy and compliance.
A fractional CFO focuses on direction.
Key differences include:
