Finance Integrations Lead

The Finance Integrations Lead will take end‑to‑end ownership of finance integration activity across the Group, with a particular focus on integrating acquired businesses into a single back‑office finance system (Microsoft Dynamics 365 Business Central). This is a hands‑on role. The successful candidate will focus on fully understanding and mapping existing processes and controls and identifying the best future target operating model. They will not only coordinate activity across finance, operations, HR and integration leads, but will also personally deliver key integration tasks. The role requires someone with the credibility, technical expertise, and influence to drive decisions, remove blockers, and ensure integrations are executed at pace and to a high standard. The role will focus initially on coordinating and delivering the integration of 13 existing businesses at various stages of transition, while developing a repeatable integration blueprint to support future acquisitions.

What You’ll Do

• Lead the end‑to‑end migration of entities onto D365 Business Central, including COA mapping, data cleansing, and opening balance reconciliations.
• Act as the primary decision‑maker and escalation point between finance users, IT specialists, and external implementation partners.
• Manage the critical “cutover” period and provide post‑go‑live support to ensure system stability.
• Challenge legacy workflows to implement consistent Group processes for AP/AR, revenue recognition, and month‑end close.
• Design and enforce robust financial controls, audit trails, and appropriate segregation of duties across all integrated units.
• Personally guide entity finance teams through their first month‑end close cycle post‑integration.
• Manage the set‑up, closure, and mandate changes for bank accounts, ensuring full cash visibility across the Group.
• Lead finance workstreams for legal entity mergers, liquidations of dormant companies, and post‑acquisition restructuring.
• Own and evolve the “Finance Integration Blueprint,” capturing lessons learned to create a repeatable, scalable model for future M&A.
• Influence senior leadership to secure resources and provide solution‑oriented updates on integration milestones.
• Perform “Go/No‑Go” readiness assessments and intervene directly to unblock project dependencies.

What We’re Looking For

• ACA, ACCA, CIMA (or equivalent) with a strong foundation in technical accounting.
• Proven track record of delivering “hands‑on” finance integrations within multi‑entity or PE‑backed environments.
• Direct experience migrating entities onto ERP systems – Microsoft Dynamics 365 Business Central is highly advantageous.
• Advanced Excel skills and a natural aptitude for data analysis, mapping, and complex reconciliations.
• Experience redesigning finance operations, controls, and reporting frameworks during periods of transformation.
• You take ownership of outcomes rather than waiting for direction, remaining calm and pragmatic under the pressure of evolving priorities.
• Ability to manage sensitive relationships during change and translate complex financial requirements for non‑finance stakeholders.
• You can balance a meticulous eye for detail with a clear understanding of the “big picture” integration goals.
• Comfortable navigating ambiguity and supporting teams through the cultural and operational shifts of a merger.
