Interim Finance Business Partner

FD Capital recruits interim Finance Business Partners for UK businesses — commercially experienced finance professionals deployed on fixed-term assignments covering vacancies, maternity leave, commercial transformation projects and specific commercial finance briefs. An interim FBP is available at short notice, embedded in the business for the duration of the assignment, and brings immediate commercial finance capability without a lengthy onboarding period. Adrian Lawrence FCA, founder of FD Capital and a Fellow of the ICAEW, leads our senior finance recruitment practice. Most interim FBP assignments can be filled within five to ten working days of brief.

The quality that distinguishes a strong interim Finance Business Partner from a strong permanent one is the ability to be commercially effective very quickly in an unfamiliar environment. Interim FBPs need to understand the business’s commercial model, identify the key relationships they need to build, and start delivering useful commercial insight within their first two weeks — not their first two months. FD Capital screens specifically for this rapid deployment and onboarding capability when placing interim FBP candidates.

When Businesses Need an Interim Finance Business Partner

FBP vacancy cover

When a Finance Business Partner leaves suddenly or goes on extended leave, the commercial functions they supported lose their finance partner immediately. Management decisions go unchallengeed from a financial perspective, the commercial analysis that the sales or operations leadership relied on stops being produced, and the CFO loses the commercial visibility that the FBP role provided. An interim FBP deployed within a week maintains that commercial finance support throughout the vacancy period and removes the pressure to rush the permanent appointment. FD Capital handles both the interim placement and the permanent search from the same brief where required.

Commercial transformation projects

When a business is undertaking a significant commercial transformation — redesigning its pricing model, entering a new market, restructuring its sales force, implementing a new CRM or CPQ system — the commercial finance analytical demand increases substantially for the duration of the project. An interim FBP with relevant commercial transformation experience provides the financial modelling and commercial analysis to support the transformation without adding permanent headcount. The assignment ends when the transformation is complete and the ongoing commercial finance requirement returns to a level the permanent team can handle.

Post-acquisition commercial integration

Following an acquisition, the acquired business’s commercial reporting needs to be integrated with the group’s commercial finance framework — revenue recognition alignment, commercial KPI harmonisation, and the build of a consolidated commercial view that the group CFO and board can use. An interim FBP with post-acquisition commercial integration experience leads this work, freeing the Group FBP team to maintain their existing partnerships during the integration period.

PE deal completion and first 100 days

In the period immediately following a private equity investment, the portfolio company typically needs to upgrade its commercial finance capability rapidly — building the revenue and commercial performance reporting infrastructure the sponsor expects, establishing the commercial KPI framework, and providing the investor pack’s commercial financial narrative. An interim FBP with PE portfolio company experience delivers this infrastructure quickly, providing the commercial finance support the sponsor requires while the business recruits a permanent FBP to own it ongoing. FD Capital’s broader private equity finance practice means our interim FBP candidates for PE-backed situations are specifically assessed for this context.

Interim FBP vs Running the Permanent Search in Parallel

The most effective response to a sudden FBP vacancy is to deploy an interim immediately and run the permanent search without time pressure. The interim maintains the commercial finance function at quality, demonstrates to the business what good FBP looks like in their specific context — which often improves the permanent hire specification — and provides a structured handover to the permanent hire when they arrive. The permanent search benefits from being run properly rather than rushed, and the commercial functions benefit from uninterrupted finance partnership throughout. FD Capital manages both the interim placement and the permanent search from the same brief, ensuring clean coordination between the two processes.
