Interim and fractional CFO in short
An interim or fractional CFO holds financial steering through a transition: management control, the closing, the forecast, the budget and the multi-year plan, and the economics of supplier relationships. The interim keeps the numbers reliable enough for leadership to decide on, and hands a steering routine to a permanent finance leader.
Keep the numbers steering the business through the transition.
A finance function can keep producing figures and still stop steering. After a departure or a reorganisation, the forecast drifts, the closing slips and leadership no longer trusts the reporting it receives.
An interim CFO holds financial steering through the transition: management control, the closing, the forecast, the budget and the multi-year plan, and the economics of supplier relationships. The seat keeps the numbers usable for decisions while the permanent finance leader is found.
When to bring in an interim CFO
- The finance function has lost its senior lead after a departure, and the closing and the forecast run without anyone who answers for them.
- Leadership no longer relies on the forecast or the reporting: the figures arrive, but nobody plans on them.
- A reorganisation changes the entities, the sites or the reporting lines, and the numbers have to hold while the structure moves.
- Supplier terms, rebates and year-end agreements weigh on the margin, and nobody follows them from negotiation to the accounts.
When it is the wrong answer
- The question is a one-off review of the numbers rather than steering them over time. An Assessment reads them once and says what they show.
- The books themselves need to be kept or audited. That is accounting or audit work, carried by those professions, not a steering seat.
- The finance team has a leader who steers well and only lacks capacity on one closing. Reinforce the team rather than add a seat above it.
What the CFO holds
- Management control: the indicators each manager is steered on, and the review that compares them with the plan.
- The closing: its calendar, who contributes what, and the checks a figure passes before leadership sees it.
- The forecast: how it is built, how often it is restated, and how far it may drift before it is challenged.
- The budget and the multi-year plan: the assumptions behind them and the trade-offs leadership is asked to make.
- Supplier economics: terms, rebates and year-end agreements, followed from the negotiation to the accounts.
The first 90 days
Days 1 to 30
- Confirm what was agreed before the seat was taken: the financial decisions it holds, the indicators that will show success, the executive it reports to and the terms of the handover.
- Trace the last closing and the last forecast step by step, and note where figures were corrected by hand.
Days 31 to 60
- Restate the management control indicators with the managers who are steered on them.
- Set the forecast routine and the threshold at which a variance is brought to leadership.
Days 61 to 90
- Run a closing and a forecast on the new routine, and compare both with what the business actually did.
- Hand the routine to the finance team members who will run it, with the checks they apply.
What you keep
- A closing calendar with contributors, checks and an owner for each step.
- A forecast method leadership plans on, with a defined threshold for raising a variance.
- Management control indicators agreed with the managers who answer for them.
- A budget and a multi-year plan whose assumptions are written down and can be challenged.
- A view of supplier terms and rebates that follows each agreement into the accounts.
We leave when the function can run without us: an identified permanent owner, a roadmap they hold, and a team that no longer routes through the interim.
Experience behind the seat
- Management control of a distribution subsidiary within a retail group, reporting to the subsidiary's head.
- Management of year-end supplier rebates for a network of member businesses, and cross-functional leadership of managers.
- Earlier management control and store management roles in retail.
Questions
- What does an interim CFO do?
- An interim CFO holds financial steering while the function has no senior lead: management control, the closing, the forecast, the budget and the multi-year plan, and supplier economics. The interim decides inside the client's reporting line, makes the numbers usable for leadership again, and leaves a routine the finance team runs on its own.
- When is an interim CFO the wrong answer?
- When the need is a one-off reading of the numbers, an Assessment gives it without a seat. When the books need keeping or auditing, accounting and audit professionals carry that work. And when the finance leader steers well and only lacks hands for one closing, reinforcing the team is enough.
- What does the CFO hand over at the end?
- At a closing, not between two. The permanent finance leader runs one closing and one forecast restatement with the interim beside them, using the written routine and its thresholds. The interim then leaves the numbers in the hands of the people who produced them, with no figure that only the interim can explain.
- Which part of finance does this seat cover?
- Financial steering and management control: the closing, the forecast, the budget, the multi-year plan and the economics of supplier relationships. The experience behind the seat comes from management control and store management in retail, listed on this page, and none of it is presented as a CFO title.
- How does the CFO make the forecast reliable again?
- By tying it to the closing and to the managers who own each line. Every restatement starts from the last closed figures, each variance beyond the agreed threshold is explained by the manager concerned, and the forecast is compared with actuals at each closing until the gaps narrow and leadership plans on it.
