Interim Financial Controller

Our client, a large and well-established not-for-profit organisation based in Winchester, is looking for an experienced Interim Financial Controller to join on a six-month contract.

The finance function is going through a period of change, with a finance system replacement planned for next year. This role will take ownership of financial control and keep day-to-day operations running while that happens, reporting to the Finance Director and working closely with the Head of Financial Operations.

Supporting the Head of Financial Operations to rebalance workload across the team

Contributing to the design of the future finance team structure

Strengthening processes and controls ahead of the finance system replacement

Keeping month-end and day-to-day finance operations running smoothly through a period of change

Suitable Candidate for the Interim Financial Controller vacancy:
