Interim Group FP&A Conusltant

Interim FP&A Consultant International Consumer Brand London

Harmonic are delighted to be partnering with a globally recognised, internationally expanding consumer brand on the search for an Interim FP&A Consultant to lead a full redesign of the group's financial reporting suite.

This is a genuinely hands-on modelling and reporting role at a business undergoing a significant finance transformation. The organisation has built an exceptional reputation within the consumer space and is now investing heavily in rebuilding its FP&A infrastructure to support continued global growth.

This role will suit a commercially minded finance professional with strong Excel modelling skills who can come in, take ownership of a reporting rebuild from scratch, and deliver a clean, practical and scalable suite of outputs that a senior finance team can work with confidently day to day.

The Role

Reporting into the Global FP&A Director, this role sits at the heart of the finance transformation programme and has a clear and defined remit: rebuild the group's entire management reporting suite. The current reporting environment is Excel-driven and in need of a complete overhaul. You will start with a blank canvas and design and deliver a full suite of reporting across actuals, forecasts, budgets, balance sheets, cash flows and variance analysis.

Critically, this is not a role for overcomplicated models or macro-heavy solutions. The business needs clean, intuitive, well-structured outputs that a proficient but non-technical finance team can maintain and use with confidence. The ability to translate complex financial data into clear, usable reporting is just as important as technical capability.

Key Responsibilities

• Lead the end-to-end redesign of the group's FP&A reporting suite, building from scratch across actuals, forecast, budget, balance sheet and cash flow reporting
• Partner with FP&A and Financial Control teams to define reporting requirements and ensure outputs support both regional and consolidated group reporting needs
• Design clear, well-structured Excel-based models and reporting templates that are intuitive for a senior finance audience without reliance on macros or complex formulas
• Support the migration of legacy consolidation and reporting models into the new ERP environment, ensuring alignment between system outputs and FP&A requirements
• Build out variance analysis capabilities and reporting packs to support executive decision-making and business performance management
• Lead data validation and reconciliation activity across old and new reporting environments, ensuring accuracy and integrity of all outputs
• Support UAT and post go-live optimisation across the reporting workstreams
• Document reporting processes, data definitions and governance to support long-term usability and knowledge transfer

What We Need to See (Essential)

• Qualified accountant (ACA, ACCA, CIMA or equivalent) or strong experience in lieu
• Exceptional Excel skills, with proven ability to build financial models and reporting suites from scratch
• Strong commercial finance background with a solid grasp of P&L, balance sheet, cash flow and variance analysis
• Experience redesigning or rebuilding management reporting in a multi-entity or international finance environment
• Strong stakeholder management skills with the ability to gather requirements and translate them into practical reporting solutions

What Would Be Advantageous

• Experience with Power BI or ERP-based reporting environments
• Background in a consumer, product-led or multi-channel retail business
• Exposure to finance transformation or ERP implementation programmes
