Updated: Aug 19
Most CEOs don’t hire CFOs very often, they may know exactly what their business needs, but have little reason to know what a good CFO interview looks like, which creates a difficult hiring decision.
The candidate in front of you speaks confidently, has worked for recognisable organisations and appears to understand finance.....
But will they take work off your plate?
Will they see trouble early?
Will their presence leave the business stronger?
To make the interview easier, I have turned these three tests into a free
CEO - Cheat-sheet: a Fractional CFO Hiring Scorecard. It gives you practical questions to choose from, shows what a strong answer should include, flags responses that need further checking and provides a simple scoring system for comparing candidates.
As a CEO You don’t need (or want) to know everything a CFO should know, so the scorecard helps you ask the questions that reveal whether the candidate can work with you, see what is coming and make the business stronger.
When you are considering a Fractional CFO, assess candidates using the scorecard's 17 questions across three key areas:
How will we work with this new CFO?
Can this CFO see what is coming and act on it?
Will this CFO make the business stronger?
1. How will we work with this new CFO?
A Fractional CFO should become part of the leadership rhythm without requiring the access or cost of a full-time executive.
The relationship needs to work when the figures are poor, the decision is uncomfortable and the CFO disagrees with you.
What will you actually take off the CEO’s plate?
This is a more useful question than asking a candidate to describe their service, because a strong candidate should be specific about the work they will own, which may include cash forecasting, monthly reporting, board papers, financial priorities and coordination with accountants or advisers. They should explain how much access they need from you, particularly during the early months, and how that will settle into a practical working rhythm.
Watch for vague promises to provide “support” without named outputs, deadlines or accountability. You should not pay for senior financial help and still find yourself chasing every action.
What happens when we don’t agree?
You don’t need another person who automatically agrees with you. Nor do you need someone who treats disagreement as a test of authority.
Ask the candidate for a real example. A good answer will show that they gathered evidence, set out the options, challenged the decision respectfully and supported the final lawful decision once it was made.
A Fractional CFO should be able to tell you something you don’t want to hear without making the relationship harder than the problem itself.
How will you work with my team and existing advisers?
The CFO should strengthen the work already being done, not create confusion around who owns what.
They should be able to work with bookkeepers, accountants, auditors, board members and operational leaders without duplicating roles or dismissing existing people before understanding the business.
Done well, the relationship should gradually feel less like hiring an external consultant and more like having a CFO you rely on and work closely with.
2. Can this CFO see what is coming and act on it?
Historical accounts tell you where the business has been. A CFO earns their place by helping you see what is likely to happen next and giving you time to respond.
How will you identify trouble before it reaches the bank account?
A capable CFO won’t rely on the current bank balance or wait for the month-end accounts.
They should explain how they connect the financial forecast to what is happening in the business, including:
Are sales converting as expected?
Are customers paying on time?
Is delivery taking longer or costing more?
Are hiring and spending commitments running ahead of revenue?
Is too much revenue dependent on one customer?
Is future growth absorbing cash faster than planned?
You are looking for an early warning system, not a late explanation.
How do you forecast when the information is incomplete?
Business forecasts are built with imperfect information. The candidate should be comfortable separating facts from assumptions, showing a sensible range of outcomes and updating the forecast as new information arrives.
Watch for false precision. Also watch for someone who refuses to form a commercial view until every number is certain. By then, the decision may have been made for you.
How will you test whether our growth plan is affordable?
Revenue growth can consume cash before it produces profit. New employees, equipment, stock, technology and additional delivery costs often need to be funded well before customers pay.
A good CFO should connect the growth plan to capacity, profit margins, working capital, investment needs and the cash position during the build-up period. They should tell you what assumptions need to hold and what would trigger a change of plan.
Seeing what is coming is useful. Acting early is the part that protects the business.
3. Will this CFO make the business stronger?
A Fractional CFO should build capability, clarity and discipline inside the organisation; not create a permanent dependency – ideally at around the 2 year point, a transition will take place to an internal Finance Controller with reducing Fractional CFO oversight.
What should happen during the first 90 days?
The first 90 days should begin with listening and learning, not arriving with a standard overhaul.
The CFO should understand how the organisation earns revenue, spends cash and makes decisions. They should meet the right people, assess the reliability of the financial information and identify the risks requiring immediate attention.
By the end of the first 90 days, you should expect:
A clear view of cash and the immediate financial risks.
More reliable reporting and forecasting.
Agreed priorities, responsibilities and deadlines.
A practical plan for the next stage of work.
Fewer financial surprises reaching the CEO late.
Be cautious of candidates who promise to replace every system before they understand the business. Be equally cautious of someone who can’t name a useful early result.
Will you make the information easier to use?
A CEO should not have to decode a 40-page report to find the decision.
The CFO should provide short, decision-focused reporting covering performance, cash, forecasts, risks, choices and agreed actions. Detailed information should be available when needed, but it should support the conclusion rather than hide it.
The test is simple: will you understand the financial position more clearly and make better decisions because this person is in the room?
These are just some of the 17 questions designed to help you as the CEO or Founder to make the best choice for your business.
This checklist is comprehensive, and you don't need to ask every question - choose the questions that reflect the pressure in your business, ask each candidate the same ones and score the answers against evidence.
Ask for evidence, not confidence
Confidence can make an interview persuasive. It can’t tell you whether the candidate has done the work they are describing.
Ask for a comparable example and listen for:
What was the problem?
What did the candidate personally do?
What options or trade-offs did they consider?
What changed as a result?
What would they handle differently next time?
Where appropriate, ask to see an anonymised forecast, monthly report or board pack. Speak to referees who directly experienced the candidate’s work and ask whether they made the business easier to run.
Be careful because job titles and well-known employers provide context, but are not always comparable - they are also not evidence of impact.
Use the scorecard to improve your comparisons
CFO interviews can be difficult to compare. One candidate may be highly polished, another may have stronger experience and a third may simply be easier to talk to.
The free Fractional CFO Hiring Scorecard gives you one place to record each answer, note any warning signs and score candidates against the same questions.
Choose the questions most relevant to your business, then score each answer from one to five:
1: Vague or concerning.
2: Significant gaps.
3: Acceptable.
4: Strong.
5: Specific, practical and supported by evidence.
Ask each candidate the same core questions. Record the score while the answer is fresh and note anything requiring follow-up.
The total won’t make the decision for you, but it will show where one candidate has demonstrated judgement and another has simply interviewed well.
Take better questions into the interview
You don’t need to become a CFO expert before hiring one. You need a practical way to test whether the candidate can take ownership, see problems early and improve the business around them.
The free Fractional CFO Hiring Scorecard includes:
Pick-and-choose questions covering the working relationship, forward planning and business improvement.
Guidance on what a strong answer should include.
Warning signs that deserve further checking.
A simple one-to-five scoring system.
Space to compare candidates using the same criteria.
