This Role

We are looking for an experienced Management Accountant to join our finance team on a six-month fixed-term contract, starting as soon as possible, with the possibility of extension. Based in London with three days a week in the office, you will report to the Financial Controller.

You will lead a clean-up of expense management, putting accurate balances and robust controls in place, and document the finance function’s key processes so any team member can run them consistently. This is a hands-on role for someone who can get up to speed quickly, work independently and leave the function in better shape than they found it.

Key Responsibilities

• Lead the expense management clean-up, reconciling accruals, prepayments, employee expense control accounts and corporate credit card accounts.

• Investigate and clear aged, unreconciled and unallocated items, proposing write-offs or corrections with supporting evidence.

• Review historic expense claims and card transactions for coding, missing receipts, VAT treatment and policy compliance, and post journals to correct the ledgers.

• Review the expenses policy and expense system set-up (including Revolut workflows, access, card limits and ledger integration) and recommend improvements.

• Work with payroll to ensure taxable expenses and P11D items are captured correctly.

• Design and implement monthly controls, reconciliations and KPIs so the clean-up holds after your contract ends.

• Map and document finance processes, including month-end close, purchase-to-pay, expenses, VAT and management reporting, as clear step-by-step manuals and a month-end close checklist and timetable.

• Walk team members through the new documentation so it is adopted, and flag gaps, duplication and control weaknesses as you go.

• Support month-end close, management accounts, variance analysis, audit preparation and budgeting and forecasting as needed.

Experience

• Strong track record in balance sheet reconciliation, including clearing aged or complex items.

• Proven experience writing clear process documentation or procedure manuals.

• Working knowledge of UK VAT and HMRC rules on employee expenses and benefits in kind.

• Experience of Sage Intacct, with hands-on Revolut experience desirable.

• Previous interim, contract or project-based clean-up work, or process improvement, internal controls or audit experience, is desirable.

Skills

• Advanced Excel, including lookups, pivot tables and data cleansing.

• Able to work independently, prioritise and deliver to deadlines with limited supervision.

• Clear communicator who can work with non-finance colleagues and challenge constructively.

• Quick to get up to speed and available at short notice.

Qualifications

• CIMA, ACCA or ACA qualified, or qualified by experience.
