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.
