10 Questions to Ask Before Hiring a Fractional CFO

How would you know 90 days in whether the fractional CFO you hired was worth the money? Most owners cannot answer that, because they hired on rapport in a single friendly call instead of on the answers that actually predict fit. Hiring a fractional CFO is a real decision with real cost, and the interview is where you find out what you are getting.

The 10 questions below sort a genuine finance partner from someone who will reformat your existing reports and send an invoice. For each one, you will see the answer you do not want and the answer you do. Ask them before you sign anything. A strong candidate gives you concrete, sometimes uncomfortable answers. A weak one gives you smooth generalities. Pay attention to which one you are hearing.

1. What would you look at first?

The wrong answer is a vague promise to "get familiar with the business." That tells you nothing and often means they have no method. A strong answer is specific: they want your last 3 months of financials, your cash position, your aging receivables, and your biggest recurring costs, and they can tell you what they expect to find. Method beats enthusiasm.

2. Who actually does the work?

Some firms sell you the senior name on the call and staff the engagement with a junior nobody introduced you to. Ask directly who will be in your books each week. A good answer names the person, describes their experience, and explains how the senior stays involved. You want to know whose judgment you are actually buying.

3. What is the monthly deliverable?

"Financial guidance" is not a deliverable. If they cannot describe what physically lands in your inbox each month, the engagement has no shape and no accountability. A strong answer is concrete: a monthly reporting package, a cash forecast, a short written commentary, and a standing call to walk through it. You should be able to picture the output before you start.

4. How do you price the engagement?

Open-ended hourly billing punishes you for asking questions and makes cost impossible to predict. Look for fixed monthly pricing tied to a defined scope, so you know the number and they know the work. If they only quote a rate with no scope attached, press them until scope and price are connected.

5. What does your first 90 days look like?

A vague answer about getting up to speed tells you they will improvise on your time. A real one has an arc. Month one is diagnostic, where they build the reporting package and learn how your cash actually moves. Month two, they surface the two or three problems that matter most. Month three, their recommendations start changing what you decide. Anyone who has done this before can tell you what you will be holding by day 90.

6. What experience do you have in my industry?

Industry matters where the economics are unusual, like construction with its progress billing, restaurants with their thin margins, or SaaS with its deferred revenue. A good answer is honest about where they have real depth and where they will lean on you to explain the quirks. Honesty here predicts honesty everywhere.

7. What is out of scope?

A candidate who says they will handle everything either does not understand scope or is about to overpromise. You want to hear clear boundaries: perhaps they do not do tax filing, or day-to-day bookkeeping, or system implementations. Knowing what is excluded protects you from assuming coverage you never bought.

8. What are the exit terms?

If it is hard to picture how the relationship ends, it will be hard to leave when you need to. The wrong answer is a long lock-in with heavy penalties. A fair answer is a reasonable notice period, usually thirty days, and a clean handoff of your files and access. Good partners are comfortable making it easy to leave, because they rarely lose clients that way.

9. What accounting systems do you work in?

If your books live in QuickBooks and their whole method assumes a different platform, you are in for friction from day one. Ask which systems they use daily and how they will fit into yours. A strong answer shows fluency in your tools and a plan for connecting the reporting layer without ripping everything out.

10. How do you handle it when we disagree?

This is the question most owners skip, and it is the most revealing. A finance partner who only ever agrees with you is not doing the job. You want someone who will tell you when a hire is premature or a price cut is a mistake, and who can do it without an argument. Listen for how they describe pushing back. That is what you are really hiring.

What good answers add up to

Read back through the answers you got. If they were specific, honest about limits, clear on scope and price, and comfortable disagreeing with you, you are talking to a real fractional CFO. If they were smooth, broad, and agreeable on everything, you are talking to someone who will not move the business. That difference is the whole point of the exercise. A fractional CFO earns their fee by changing decisions, and you can hear whether someone will do that in how they answer these 10 questions.
