Short answer
Hire an interim CFO when three things are true at the same time: the problem is CFO-level, it cannot wait for a permanent search, and someone must own the outcome rather than only advise. If you only need recurring senior input, fractional may be better. If the need is mainly reporting/control execution, a Finance Director can be the better answer.
Seven signals
1. The CFO seat is empty
The search will take months but cash, board cycles and leadership continue.
2. Cash is not predictable
No reliable 13-week view or clear working-capital ownership.
3. The forecast is not trusted
The story changes every month and decision-makers cannot rely on it.
4. EBITDA is off plan
The gap is known but the bridge to price, volume, mix, cost and productivity actions is not.
5. PE ownership raises the bar
Board reporting, cash discipline and value-creation cadence need to mature quickly.
6. Integration creates noise
Entities, systems, KPIs and teams need one finance operating model.
7. The permanent role needs a reset
An interim can stabilise the function and sharpen what the long-term CFO profile should be.
Which model fits?
| Situation | Likely model | Reason |
|---|---|---|
| CFO left; board/lenders need immediate ownership | Interim CFO | Full temporary responsibility. |
| Stable company; CEO needs one day a week senior input | Fractional CFO | Recurring leadership without a full-time mandate. |
| Reporting, team and close need strengthening while CFO remains | Finance Director | Execution capacity under the existing CFO. |
| One financing or board question | CFO Advisory | Targeted senior judgement. |
How to hire well
- Define the outcome, not only the title.
- Make the first 30/60/90-day deliverables explicit.
- Match the candidate to ownership and complexity context.
- Test both board-level judgement and hands-on operating depth.
- Agree what a clean handover looks like.
