About the Role

We are looking for a proactive, detail-oriented Accounts Assistant to join our Finance team on a 12-month fixed-term contract.

This role is initially focused on reducing our Accounts Payable backlog, while helping improve efficiency in our finance processes. Once the backlog is cleared, you will continue to support the transactional finance function, including supporting the Accounts Receivable team, month-end activities, process mapping, data cleansing, and preparation for a new finance ledger system.

This is a fantastic opportunity for someone who enjoys working in a fast-paced environment, improving processes, and delivering accurate, high-quality financial work. You’ll gain hands-on experience across the full finance function and play a key role in shaping how we work.

What you’ll be doing.

• Process supplier and debtor invoices, verifying accuracy and resolving discrepancies.

• Record and allocate customer payments, investigating any unallocated transactions.

• Schedule and process supplier payments while maintaining accurate transaction records.

• Maintain purchase and sales ledgers, including postings, reconciliations, and period maintenance.

• Monitor aged payables and receivables, preparing balance and cash flow forecasts.

• Perform regular bank and balance sheet reconciliations with supporting schedules.

• Set up supplier accounts, validating VAT registration and key information.

• Process employee expenses and corporate credit card transactions in line with company policy.

• Support month-end activities, including prepayments, foreign exchange adjustments, and ledger maintenance.

• Ensure appropriate documentation, approvals, and audit trails in line with internal controls.

• Respond to supplier and customer queries professionally and collaborate internally to resolve issues.

• Identify and implement process improvements across Accounts Payable and Receivable.

• Support process mapping and data cleansing ahead of new ledger implementation.

• Provide support to the wider Financial Accounts team as required

What We’re Looking For

• Previous experience in an accounts payable, accounts receivable, finance assistant or similar roles.

• A finance-related qualification (e.g. AAT Level 2 or 3) is preferred but not essential.

• Experience working with high volumes of financial data

• Proficient in Microsoft Excel

• Familiarity with accounting software (e.g., Sage, NetSuite, or similar ERP systems) if preferred

• High level of numerical accuracy and strong attention to detail

• Ability to prioritise workload and meet deadlines

• Confident communicator, able to liaise effectively with stakeholders at all levels

• Proactive mindset with a focus on continuous improvement

What we offer in return:

• 28 days of annual leave days

• Pension Scheme

• Employee Assistance Program (EAP)

• Social events and much more
