Interim Controller – Accounting Transformation

A PE-backed services business with revenues exceeding $100M is seeking an Interim Controller to cover a temporary leadership gap. The engagement is project-based and short in duration, with a preference for a candidate who can start immediately. The current accounting environment is highly manual, with a month-end close cycle running at approximately 20 days. The incoming Controller will work directly alongside the CFO to stabilise reporting, provide structure to an existing lean team, and assess where process discipline and automation can reduce that timeline materially.

The role combines hands-on operational delivery with a clear diagnostic mandate. Beyond keeping the close on track, the successful candidate will develop a prioritised roadmap of practical improvements the business can implement during and after the engagement. Sage Intacct experience is strongly preferred. Prior exposure to Private Equity-backed environments is required.

• Oversee and stabilise the month-end close process, ensuring reporting deadlines are consistently met.
• Lead day-to-day direction of a lean accounting team covering FP&A, accounts receivable, accounts payable, and payroll.
• Partner with the CFO to surface issues, prioritise needs, and maintain continuity across the engagement.
• Review existing workflows and close procedures to identify inefficiencies, redundancies, and automation opportunities.
• Introduce greater process discipline, accountability, and structure to the accounting function.
• Deliver a clear, prioritised improvement roadmap with actionable recommendations for reducing the close timeline.

• Proven background as a Controller, Assistant Controller, or senior accounting leader with strong month-end close experience.
• Previous experience in a Private Equity-backed business environment (required).
• Demonstrated ability to assess accounting processes quickly and identify inefficiencies.
• Solid understanding of accounting controls, reconciliations, and financial reporting standards.
• Experience shortening close timelines and implementing process improvements within lean teams.
• Sage Intacct experience highly preferred; comfort working directly with CFO-level stakeholders essential.
