Interim CFO: Role And Benefits of Hiring

What is an interim CFO? Role, job description and when to hire one

The CFO is about to start six months of leave, and a buyer has just asked for diligence data. Nobody on the finance team has run a deal before. An interim CFO fills a seat like this one.

An interim CFO is a senior finance executive hired for a fixed period, usually three to twelve months. They run the finance function until a permanent leader arrives or a specific event is over. The role carries the same authority as a permanent CFO, with a defined end date.

This guide explains what an interim CFO does and gives a sample job description you can adapt. It also covers when to hire one, how the role differs from a fractional or permanent CFO, what the first 90 days look like, and how to hire well.

What does an interim CFO do?

An interim CFO takes over the seat, not just the title. The job is to keep the business safe and moving while the situation resolves. The mix changes by engagement, but most cover the same eight areas.

Area	What the interim CFO does
Stabilize	Reviews cash, debt, covenants and open risks in the first days, and confirms banking and signing access
Reporting	Owns the monthly close, the financial statements and board or investor packs
Cash and liquidity	Builds a rolling cash forecast and fixes shortfalls before they hit
Planning	Runs the budget, the forecast and variance reviews
People	Leads the finance team and covers gaps left by the departing CFO
Lenders and investors	Takes the calls, answers diligence questions and keeps relationships calm
Events	Leads the finance work behind a raise, sale, acquisition or restructuring
Handover	Documents processes and briefs the permanent CFO

An interim CFO leads the existing team. They do not replace it. Daily bookkeeping still belongs to your accountants or controller.

Interim CFO job description

Employers who search for this term usually want a template. Use the version below and edit it to fit your situation. Add the specific outcomes you expect in the first 90 days, because a vague brief produces a vague engagement.

Job summary. The interim CFO provides senior financial leadership for a defined period. The role oversees accounting, reporting, cash management and planning. It supports the executive team and the board, and it prepares the business for a permanent CFO or for the completion of a named event.

Responsibilities

• Lead all finance and accounting operations, including the monthly and year-end close
• Produce accurate financial statements and management reports on a fixed schedule
• Manage cash flow, liquidity and the rolling cash forecast
• Own the budget, the forecast and variance analysis
• Manage relationships with banks, lenders, investors and auditors
• Support or lead a named event, such as a raise, due diligence, a sale or a restructuring
• Strengthen internal controls and compliance
• Lead and mentor the finance team
• Document processes and hand over to the permanent CFO

Qualifications

• Previous experience as a CFO, VP of finance or senior finance executive
• Degree in accounting or finance, with CPA, ACA, ACCA, CIMA or an equivalent qualification preferred
• Direct experience with the event the business faces
• Hands-on command of accounting systems and Excel
• Clear communication with non-finance leaders, boards and lenders

Engagement terms. State the term (often three to twelve months), the hours, the reporting line and the signing authority. Hours are usually full time. Smaller companies sometimes ask for 10 to 20 hours a week. The reporting line is normally the CEO. Recruiter postings in the US and UK commonly ask for prior CFO experience and a professional qualification, so expect strong candidates to hold both.

Interim vs fractional vs permanent CFO

The three models solve different problems.

	Interim CFO	Fractional CFO	Permanent CFO
Time	Usually full time	Part time	Full time
Length	Fixed, often 3 to 12 months	Ongoing	Open-ended
Best for	A vacancy, a leave or a transition	Ongoing senior input on a budget	A stable, long-term need
Exit	Defined end date	Notice period	Notice and severance

If the CFO seat is empty today, interim is usually the fit. If the seat was never filled and you need steady planning help, look at a fractional CFO instead. Our guide on whether you need an interim or part-time CFO compares the models in detail. For the part-time option, read what a fractional CFO does.

When to hire an interim CFO

Hiring an interim CFO is event-driven. Six situations come up most often.

1. The CFO leaves. A resignation or dismissal leaves lenders, auditors and staff without a point of contact. An interim holds the seat while the search runs.
2. A leave of absence. Parental or medical leave can last months. An interim covers the gap and briefs the returning CFO.
3. A fundraise. Investors judge the finance function as closely as the product. An interim keeps the data room and the numbers credible through the close.
4. A sale or acquisition. Deals need diligence, quality-of-earnings work and integration planning. An interim with transaction experience can run it alongside the business.
5. A turnaround or restructuring. A business in difficulty needs someone to triage cash, talk to creditors and build a recovery plan.
6. The controller has outgrown the job. When a controller is doing CFO work without the title, an interim bridges the gap until a permanent hire is ready.

If none of these fits, you may not need an interim CFO. A fractional CFO or cleaner books may serve you better.

Benefits of hiring an interim CFO

The case for an interim rests on five practical gains.

• Speed. An interim can start in days or weeks, while a permanent search takes months.
• Senior skill without long-term cost. You pay for experience during the engagement, with no benefits, equity or severance afterwards.
• Objectivity. An outsider sees the business the way lenders and investors do, and spots problems the team has stopped noticing.
• Continuity. Staff, banks and investors see that finance leadership is in place, which calms a tense period.
• A trial run. Some companies use the engagement to test what a CFO should do before they write the permanent job description. Others convert the interim into the permanent hire.

There are trade-offs. An interim needs time to learn the business, the monthly cost is higher than a fractional arrangement, and a poor handover can undo the gains. A clear scope and a written handover plan reduce all three risks.

What the first 90 days look like

A structured start separates a useful engagement from an expensive one.

Window	Focus	Output
Days 1 to 7	Secure banking and signing access, check payroll and vendor runway, review cash, brief the board and lenders	Cash position and risk list
Days 8 to 30	Review the books and the close, build a 13-week cash forecast, meet the team and stakeholders	Reliable forecast and reporting calendar
Days 31 to 60	Fix the priority issues, tighten controls, support the named event	Action plan with owners
Days 61 to 90	Deliver results, document processes, start the handover or agree an extension	Handover file or extension decision

After day 90, the scope depends on the event. Some engagements end cleanly. Others become a permanent hire or a fractional arrangement.

Interim, temporary, contract and bridge CFO

These labels mostly describe where the person comes from or how urgent the hire is. The job is the same. An interim chief financial officer, a temporary CFO and a bridge CFO all fill the seat for a limited time. What changes is who you contract with and who stands behind the work.

How to hire an interim CFO

Four steps keep the process short.

1. Define the event and the outcomes. Write down what must be true when the interim leaves. A clean close, a funded round or a signed deal are all outcomes. “Help with finance” is not.
2. Choose a source. A partner-led firm sends a senior person from its own bench. A staffing agency places a contractor on your payroll. A search firm treats the interim as a bridge to a permanent hire. An independent consultant works directly with you. Our comparison of interim CFO firms shows how five providers work.
3. Vet candidates. Ask each one:
   • Who will do the work, and can I meet them first?
   • Have you handled this event before?
   • How many other engagements will that person run at the same time?
   • What does your first week look like?
   • What will you hand over at the end?
4. Agree the terms. Fix the scope, the hours, the signing authority, the notice period, the handover deliverable and any conversion terms if you might hire the person permanently.

What does an interim CFO cost?

Rates vary by country, seniority and hours. The table collects published reference points from different markets.

Source	Rate	Scope
US comparison by a fractional CFO firm	$15,000 to $35,000 a month	Full-time interim retainers
US recruiter posting	$80 to $100 an hour	10 to 20 hours a week
London recruiter posting	£720 to £880 a day	Interim CFO in the charity sector
Expert360, Australia	A1,400toA2,500+ a day	SME to complex or transactional work

Treat these as reference points, not quotes. A firm with a senior partner on your account costs more than a lone contractor, and an emergency start costs more than planned cover. For part-time pricing, read the cost of a fractional CFO.

Frequently Asked Questions

An interim CFO runs the finance function for a limited time. They manage reporting, cash, planning and the finance team, and they lead any event that triggered the hire, such as a fundraise or a sale.

How long does an interim CFO stay?

Is an interim CFO the same as a fractional CFO?

What qualifications should an interim CFO have?

Look for past experience as a CFO or senior finance executive, plus a degree in accounting or finance. A CPA, ACA, ACCA, CIMA or equivalent qualification helps. Direct experience with your situation matters most.

How quickly can an interim CFO start?

Firms that specialize in interim placements often quote one to two weeks, and emergency cover can be faster. A permanent search takes several months. Ask any provider to commit to a start date in writing.

Can an interim CFO become permanent?

Sometimes. Some companies convert the interim into the permanent CFO. Agree the possibility at the start, and check any conversion fee in a staffing contract.

Judge the engagement by its last day

An interim engagement is judged on the day it ends. Before you sign, ask each candidate to describe the finance function as it will look when they leave: who owns the close, what the cash forecast covers and what the board will see. A clear answer predicts a clean handover.
