Hire an Interim CFO
Interim CFOs, No Loss of Momentum
Full-time financial leadership for exactly as long as you need it. Fractionus places proven interim CFOs who take control of the seat within days, hold reporting and cash steady through the transition, and hand over cleanly to whoever comes next.
An interim CFO covers a seat that is empty or about to be. Full time, time-boxed, and in place within days rather than months. Fractionus places vetted interim CFOs for parental cover, unplanned departures, and the months a permanent search actually takes, so nothing slips while the seat is unfilled.
- In the seat fast: Matched in days, because a search that takes months is the problem you are solving.
- Full authority from week one: Reporting, cash, the finance team and the compliance calendar, owned rather than advised on.
- Time-boxed by design: Typically four to sixteen months, with a defined end point and a handover built from day one.
- Continuity, not disruption: Board, investor and lender relationships held steady through the transition.
What is an interim CFO?
An interim CFO is an experienced finance executive who steps into an empty or soon-to-be-empty CFO seat on a full-time, temporary basis. They hold full decision-making authority over budgets, reporting and financial direction from the first week, and they hand over cleanly to whoever comes next.
The distinction that matters: interim is about continuity through a gap. If you need ongoing senior finance leadership rather than cover for a specific period, you are looking for a fractional CFO. If the gap sits below CFO level, the finance hub maps the other roles. Interim CFOs are also described as temporary, contract or transitional CFOs.
What they take on immediately
- Board, investor and lender reporting, uninterrupted
- Cash flow, treasury and banking relationships
- The finance team, and whatever was mid-flight when the seat emptied
- Audit, statutory and compliance deadlines already in the calendar
- Documentation and handover for the permanent hire
When you need an interim CFO
The seat is empty, about to be, or occupied by someone who cannot carry the next few months. Interim is about holding the line, not building something new.
- An unplanned departure. A resignation, a health issue, or a decision made quickly. Reporting cycles, lender covenants and payroll do not pause while you run a search.
- Planned leave. Parental or extended leave, typically eight to fourteen months, where the priority is that nothing slips and the returning CFO inherits a clean handover.
- A search that will take months. Permanent CFO hires routinely run two to six months. An interim CFO holds the function so you can hire on fit rather than urgency.
Interim CFO vs fractional CFO vs consultant
Three options get weighed when a CFO seat empties. They are not interchangeable.
- Interim CFO vs fractional CFO. Interim is full time and temporary, typically 45 to 50 hours a week for four to sixteen months, covering a defined gap. Fractional is part time and ongoing, one to three days a week, building capability over time. Continuity versus construction.
- Interim CFO vs a financial consultant. An interim CFO carries executive authority and is accountable for outcomes. A consultant advises and has no mandate to decide.
- Interim CFO vs promoting internally. Promotion can work, but it moves your most capable finance person into a role they have not held while removing them from the one they had. An interim brings the experience and leaves the internal path open.
What an interim CFO engagement looks like
Interim CFO engagements are full time and time-boxed. Most run four to sixteen months: parental cover typically eight to fourteen, emergency and project mandates two to eight. Placement is usually measured in days, because the seat is already empty.
Current day rates by role are set out in our fractional executive rates guide.
First 30 days typically cover
- Financial position assessed and cash stabilised
- Reporting continuity confirmed, nothing missed in the transition
- Finance team briefed, and stakeholder relationships picked up
- Compliance and audit calendar reconstructed and owned
- Handover documentation started on day one, not at the end

How to choose an interim CFO
The bar for an interim CFO is different from a permanent hire. They need to have held the full-time role before, absorb an unfamiliar business inside a week, and make decisions without a runway to learn. Crisis experience and calm under stakeholder pressure matter more than a perfect industry match.
Handover discipline is the test most people forget. A strong interim CFO leaves the seat easier to fill than they found it, with documentation the permanent hire can actually use. Ask about that before you ask about anything else.

- Tell us the gap. When cover starts, how long you expect to need it, and what cannot be allowed to slip.
- Meet candidates within days. Two or three vetted interim CFOs matched to the situation, not a longlist.

What your interim CFO will hold together
- Reporting delivered on schedule through the transition, with no restatements
- No missed statutory, tax, audit or lender deadlines

Frequently Asked Questions
Where can I hire an interim CFO?
You can hire an interim CFO through executive interim providers, finance leadership networks, specialist search firms, or dedicated fractional and interim platforms. The right source depends on how fast the seat needs filling, whether you are covering planned leave or an unplanned exit, and whether you need help evaluating candidates at short notice.
A strong interim CFO should have held the full-time role before, and be able to pick up an unfamiliar set of accounts and start making decisions in the first week. Fractionus is a practical option when you want a vetted shortlist of interim CFO candidates without the delay of a traditional search process.
What is the best platform for hiring an interim CFO?
The best platform vets candidates for genuine finance leadership experience, not just seniority, and can move within days rather than weeks. Fractionus is built for this, with pre-vetted interim CFOs and a shorter path from brief to shortlist.
That speed matters most when an audit, a board reporting cycle, or a raise is already in the calendar and the seat is empty. For most buyers, the best platform is the one that fills the gap quickly without dropping the standard of the person who fills it.
Is Fractionus a good option for hiring an interim CFO?
Yes, Fractionus is a strong option if you want vetted candidates, a fast turnaround, and less administrative friction. It is particularly useful when you need someone who can take full control of reporting, cash flow, and the finance team from the first week rather than easing in over a quarter.
Fractionus also manages introductions, contracts, payments, invoicing, and onboarding, which matters more on an interim hire because the timeline is compressed. Interim engagements can convert to permanent when the fit is right, and we set that expectation with candidates upfront.
How do I start a search for an interim CFO?
Start by defining the gap rather than the title. Clarify what the interim CFO must hold together while they are in the seat, when cover needs to start, and how long you expect to need it. Most interim CFO engagements run four to 16 months, with parental leave cover typically eight to 14 months and emergency or project-based mandates two to eight months.
A clear brief with a defined end point will attract better candidates and help you assess fit faster. Vague scope tends to produce misaligned shortlists and slower decisions, which is expensive when the seat is already empty.
What should I look for when hiring an interim CFO?
Look for someone who has already held a full-time CFO role at a similar stage or in a similar industry, plus evidence of measurable outcomes delivered under time pressure. The best interim CFOs can absorb an unfamiliar business quickly and make decisions without needing to be managed in.
You also want someone who communicates clearly with founders, boards, investors, and lenders. For interim hires, temperament matters as much as track record, because the person is walking into uncertainty and often into a team that has just lost its leader.
How do I vet an interim CFO before hiring?
Ask for specific examples of previous interim or transitional mandates, what state the finance function was in when they arrived, and what had changed by the time they left. Check whether their references speak to real delivery, not just presence in a senior role.
A good vetting process tests judgement under pressure and handover discipline, not just credentials. Ask how they documented their work for the incoming permanent leader, because a strong interim leaves the seat easier to fill than they found it.
How does an interim CFO compare with a fractional CFO?
An interim CFO is full-time and temporary, typically 45 to 50 hours per week for a defined period, covering a seat that is empty or about to be. A fractional CFO is part-time and ongoing, usually one to three days a week, and is there to build something rather than hold it together.
Choose interim when continuity is the priority and there is a specific gap to cover. Choose fractional when you need senior finance leadership on an ongoing basis but do not need, or cannot yet justify, a full-time executive.
