Job description

We are looking for aproactive and detail-oriented Assistant Accountant to join a busy, high-performing finance team in London on a fixed-term (maternity cover) basis. You will manage key transactional processes across accounts payable and receivable, support reconciliations, month-end and year-end activities, and ensure accuracy while meeting tight deadlines.

What you’ll do

Administer the accounting system, maintaining user hierarchies, setting up new users, and assigning processing, reporting, and workflow rights.

Attend promptly to general finance queries and provide support across the team.

Reconcile fortnightly travel invoices and monthly credit card statements, obtaining approvals and uploading transactions to the accounts system.

Raise sales invoices across all group companies and support credit control activities, keeping detailed records of all debtor communications.

Provide cover for the other assistant accountant, including purchase ledger processing, payment runs, and bank transaction postings.

Perform ad hoc analysis and support month-end and year-end activities.

What you’ll need

Proven experience in accounts payable and accounts receivable within a structured, high-volume finance environment.

Experience using a finance system, preferably Sage 200, and familiarity with payment systems and Microsoft applications.

Hands‑on experience working in nominal, sales and purchase ledgers, and cashbook.

Ability to multi‑task, work under pressure, and meet tight deadlines.

High level of accuracy, attention to detail, and strong organisational skills.

Effective communication skills and a collaborative, team-oriented approach.

Qualifications such as AAT are an advantage but not essential – personality, motivation, and a strong work ethic are highly valued.

Fixed‑term role with career progression opportunities.

Exposure to multiple areas of finance in a professional, collaborative environment.

Opportunity to develop skills in AP, AR, reconciliations, and reporting using modern finance systems.

Supportive team with hybrid working options and flexible arrangements.

Don’t miss out – apply early to be considered for this exciting opportunity.
