Finance Business Partner - Commercial & Sales in Lewes

The Finance Business Partner is the primary financial voice to the Commercial and Sales teams, translating financial performance into commercial insight. This forward-looking, relationship-driven role involves challenging assumptions with evidence, building trust quickly with senior stakeholders, and driving the business to move faster and with greater confidence.

What You’ll Be Doing

• Provide proactive financial challenge and support to commercial decisions, including pricing, promotions, channel strategy and new product launches.
• Translate financial data into clear, actionable insight that drives action, not just reporting.
• Own the commercial performance narrative: revenue, gross margin, channel mix, CAC, ROAS and customer-level profitability.
• Produce weekly and monthly trading analysis, identifying key drivers, variances to plan, and emerging risks or opportunities.
• Support post-promotion and campaign evaluation, ensuring investment decisions are grounded in financial returns.
• Monitor SKU-level and channel-level performance, working with the FP&A Analyst to ensure granular accuracy.
• Lead the commercial input into the budget and reforecast cycles, working closely with Sales and Commercial teams to build credible, bottom-up plans.
• Own the commercial forecast within the rolling forecast process, ensuring assumptions are current, well-reasoned and clearly documented.
• Build and maintain financial models that support scenario planning and commercial sensitivity analysis.
• Contribute to the S&OP process with robust commercial and financial data.
• Prepare high-quality analysis packs and presentations for trading reviews, board updates and ad-hoc commercial decisions.
• Develop a deep understanding of the commercial model: channel economics, customer contribution, promotional ROI and category dynamics.
• Surface trends and issues proactively – don’t wait to be asked.
• Bring an outside-in perspective: benchmark performance, identify analogues and stress-test assumptions.
• Identify and drive improvements in how commercial performance is tracked, reported and understood across the business.
• Work closely with the FP&A team to ensure data integrity and consistency between commercial and central reporting.
• Support the development of scalable, repeatable commercial finance tools and templates.

Qualifications

• Qualified accountant (ACA, ACCA or CIMA).
• Demonstrable experience in a business partnering or commercial finance role, ideally within a consumer goods, FMCG, DTC or similar fast-paced environment.
• Comfortable working with commercial and sales teams – you understand their language, priorities, and pressures.
• Strong financial modelling and analytical skills, with the ability to structure complex problems and present findings clearly.
• Experience working within a budgeting and forecasting cycle, with ownership of commercial inputs.
• Clear communicator: able to distil complex financial information into concise, compelling narratives for non-finance audiences.
• Proactive and curious: you seek out insight rather than waiting for questions to be asked.
• Commercially minded: you think like a business owner as well as a finance professional.
• Collaborative by nature: you build relationships easily and are trusted by the teams you work with.
• Detail-oriented but not detail-bound: you know when to go deep and when to step back to see the bigger picture.
