Fractional Finance Business Partner Recruitment

Fractional Finance Business Partner

FD Capital places fractional Finance Business Partners for UK businesses — experienced commercial finance professionals who work across multiple businesses simultaneously on a day-rate basis, typically one to two days per week per client. A fractional FBP gives growing businesses access to senior commercial finance capability — the analytical insight, stakeholder engagement and commercial challenge that a Finance Business Partner provides — at a cost proportionate to the business’s current scale and stage. Adrian Lawrence FCA, founder of FD Capital and a Fellow of the ICAEW, leads our senior finance recruitment practice.

What a Fractional Finance Business Partner Does

Commercial finance support to operational functions

The fractional FBP’s primary work is partnering with the business’s operational and commercial functions — attending the relevant leadership meetings on their allocated days, providing financial analysis that supports the decisions those functions need to make, and challenging assumptions in plans and forecasts with the rigour that finance brings but that purely commercial teams often lack. In practice this means working alongside the sales leadership to understand pipeline conversion and revenue forecasting, partnering with operations on cost drivers and efficiency initiatives, supporting the marketing function with spend attribution and return on investment analysis, and providing the CFO or Finance Director with a more granular view of commercial performance than the monthly management accounts alone provide.

Business performance analysis and KPI development

A fractional FBP with commercial finance experience brings a structured approach to performance measurement — helping the business identify the right KPIs for its commercial functions, building the dashboards and reporting frameworks that track those KPIs consistently, and providing the analytical context that turns raw performance data into actionable insight. Many growing businesses track activity metrics — calls made, proposals sent, pipeline value — without the financial overlay that shows whether that activity is generating sustainable returns. The fractional FBP builds that overlay and presents it in a format that commercial leaders can use.

Budget challenge and commercial planning support

The fractional FBP plays a significant role in the annual budget process — not by building the budget model (that is typically the FP&A function’s responsibility) but by challenging the commercial assumptions that go into it. Revenue forecasts built by sales teams are routinely optimistic; cost plans built by operations are routinely incomplete. A commercially experienced FBP who knows the business’s historical conversion rates, average deal sizes, customer churn patterns and cost drivers provides the CFO with an independent check on the commercial inputs to the financial plan. This is a specific and valuable contribution that justifies the fractional engagement even for businesses that have a capable internal FP&A function.

Investment and commercial decision support

When the business is evaluating a significant commercial decision — entering a new market, launching a new product, acquiring a customer, renegotiating a major supplier contract — the fractional FBP builds the financial analysis that quantifies the decision. This includes scenario modelling of the financial outcomes, sensitivity analysis of the key assumptions, and the financial narrative that supports the management team’s decision-making process. These project-based analytical pieces are particularly suited to the fractional model because they have a defined scope and output rather than requiring ongoing presence.

Fractional FBP vs Part-Time FBP — The Key Distinction

A fractional Finance Business Partner works across multiple businesses simultaneously on a day-rate basis — typically self-employed or operating through a limited company, outside IR35 in most cases, and dividing their time between clients. They are not exclusively available to any single business on their allocated days and work to the output-focused brief rather than as an embedded team member.

A part-time Finance Business Partner is employed by a single business on a reduced-hours contract — two to three days per week — with full employment rights and exclusive availability on their contracted days. For businesses where the FBP role requires attendance at recurring management meetings, deep knowledge of the business’s specific commercial context, and the trust that comes from being a known member of the team, the employment model is usually the better fit. For businesses that need commercial finance expertise deployed against specific outputs without the overhead of an employment relationship, fractional works well. See HMRC’s IR35 guidance for the tax implications of the different structures.

When Fractional FBP Works Best

Scale-ups building commercial finance capability for the first time

Businesses at Series A or Series B stage often have strong commercial teams — sales, marketing, product, operations — that have grown quickly but have never been supported by a dedicated commercial finance partner. The CFO or Finance Director is typically focused on the management accounts and investor reporting rather than the deep commercial partnering work. A fractional FBP brings that commercial finance capability at the right cost for the stage of the business, partnering with the commercial functions one to two days per week while the business builds toward a scale that justifies a permanent hire.

Businesses with a specific commercial finance project

A business launching into a new market, implementing a new pricing model, preparing for a significant commercial negotiation or building a new product’s financial model has a defined commercial finance need with a clear end point. A fractional FBP engaged on a project basis delivers the analytical output without the business needing to hire a permanent employee for a finite piece of work. FD Capital regularly places fractional FBPs for project assignments of eight to sixteen weeks alongside longer-term recurring day-rate engagements.

PE-backed businesses between permanent FBP hires

When a Finance Business Partner leaves a PE-backed business, the ongoing commercial partnering requirement does not pause while the permanent search runs. A fractional FBP maintains the commercial finance support to the business’s functions throughout the search period, ensuring the next board pack has the same quality of commercial analysis as its predecessors and providing continuity for the commercial teams that depend on financial partnership. FD Capital handles both the fractional placement and the permanent search from the same brief where required. Our broader private equity finance practice means fractional FBP candidates for PE-backed engagements are specifically assessed for investor reporting and value creation plan context.
