How to Evaluate a Fractional CFO

There are more people calling themselves fractional CFOs right now than at any point in history.

Some of them are excellent. Some of them are controllers who built a website. The difference matters — because the wrong hire at the CFO level costs more than no hire at all.

What to Actually Look For

Operating experience, not just advisory experience. There's a meaningful difference between someone who has sat in the CFO seat of a real business — with headcount, board relationships, and P&L ownership — and someone who has advised from the outside. Ask specifically: have you ever been the most senior finance person in a company? What did you own?

Cross-functional scope. The best CFO work happens at the intersection of finance and the rest of the business — marketing, operations, sales, HR. If every answer a CFO gives starts and ends with the numbers, they're a strong controller. If they can tell you how a comp structure is destroying gross margin, or how your payback window is creating a working capital problem, that's a different conversation.

A clear methodology. Generic CFO help ('I'll look at your financials and tell you what I find') is worth less than structured CFO help. Ask what their framework is. How do they prioritize? How do they think about building a finance function that scales? If the answer is 'it depends,' keep looking.

Proof, not promises. Case studies, specific outcomes, named metrics. Not 'I helped a company grow revenue' — 'I rebuilt their close process from 14 days to 5, restructured the AP function, and freed up $300K in annual labor costs.' Specificity is the tell.

References from operators, not just other advisors. Talk to a CEO or founder who worked with them. Ask what changed. Ask what was hard. Ask if they'd hire them again.

The fractional CFO market is big enough now that you have real choices. Use them.
