The Role

The FP&A Manager is the financial insight engine of the Finance function -- turning financial and operational data into clear, forward-looking insight that drives better decision-making across the business.

This is not a reporting-only role. You will interpret performance, challenge assumptions, and translate ARR, MRR, KPIs and forecasts into actionable insight that influences revenue growth, profitability and strategic direction.

You will take a hands-on approach to analysis and modelling, building and owning outputs end-to-end.

Working across Finance, RevOps and commercial teams, you will bring revenue, cost and cash together into a single, coherent and trusted view of business performance. You will work closely with business leaders, RevOps, the Management Accountant, Credit & Ops Manager and Head of Finance to identify risks early, unlock opportunities, and enable better, faster decisions.

Revenue & ARR / MRR Insight

• Own the integrity of ARR/MRR, ensuring accuracy and alignment across systems alongside RevOps.

• Deliver clear monthly reporting with actionable insight on movements, risks and opportunities.

• Carry out detailed analysis of revenue movements, drivers and variances to inform decisions.

• Partner with RevOps, Sales and CX to improve billing accuracy and revenue visibility.

• Track leading indicators (churn, expansion, pipeline trends) and proactively flag risks and opportunities.

• Ensure new business goes live and ramps as expected, removing blockers early.

• Prepare and present insight-led outputs for leadership discussions.

Performance & KPI Visibility

• Own and evolve business KPIs (NRR, LTV, CAC, ARPU, growth, gross profit), ensuring they are clearly defined, consistent and aligned across the business.

• Deliver weekly and monthly KPI reporting, with clear trend analysis and forward-looking commentary.

• Perform hands-on analysis of KPI performance and drivers, translating movements into clear actions.

• Ensure KPIs are visible, understood and actively used across the business.

• Provide insight to support commercial decisions and margin improvement.

Forecasting, Budgeting & Planning

• Own billing and revenue forecasts (monthly and rolling), integrating inputs from RevOps, Sales and CX.

• Analyse performance vs forecast and budget, driving actions with stakeholders to close gaps.

• Support delivery of the 3-year plan, annual budget and reforecasts with the Head of Finance.

• Build and own forecasting and scenario models, taking a hands-on role in model development.

• Deliver scenario and sensitivity analysis to support decision-making.

• Provide monthly run-rate and variance analysis alongside the Management Accountant.

Cash Flow & Treasury

• Own weekly and monthly cash flow reporting, ensuring accuracy and clear commentary on position and outlook.

• Prepare scenario-based cash flow forecasts incorporating historical trends, projected inflows/outflows and business initiatives.

• Optimise cash balances and short-term deposits, providing forward-looking recommendations on liquidity.

Process Improvement & Insight

• Continuously improve forecasting, reporting and planning processes.

• Enhance dashboards and data visibility across Finance

• Identify and implement automation opportunities to reduce manual processes and improve efficiency and scalability across reporting and forecasting.

• Champion insight-led finance -- ensuring outputs drive action, not just reporting.

Ad Hoc & Business Support

• Provide limited cover for key Finance and RevOps activities during periods of absence, ensuring continuity of reporting and forecasting.

• Support business cases, strategic initiatives and cross-functional projects.

• Contribute to a collaborative, high-performing finance function.
