Job description

Office based - Potters Bar (Hertsmere) | Monday-Friday, 08:00-17:00

We're looking for an Accounts Assistant to join the finance team at our Potters Bar head office. You'll work across the group's day-to-day finance - purchase ledger, reconciliations and weekly reporting - as part of a small, established team.

Our processes are well established, and full training is provided on our systems. You won't need experience of every area of the role - we're just as interested in someone with a grounding in purchase ledger or transactional finance who is ready to broaden their remit - as we are in an experienced Accounts Assistant looking for a varied, hands‑on position.

Key Responsibilities

Working alongside the finance team, you'll cover a broad mix of transactional finance across the group:

• Purchase ledger - setting up suppliers and subcontractors, processing and coding invoices, resolving queries, and preparing the weekly payment runs for review and authorisation.
• Weekly pay and bill - checking and reconciling the group's timesheet, invoice and payment data, and uploading invoices and self-bills into the finance system.
• Reconciliations - bank, company car, fuel and insurance reconciliations, together with staff expenses.
• Reporting - producing our regular weekly and monthly sales and finance reports, and providing information in response to ad‑hoc queries.
• Month-end support - checking ledgers, finalising reconciliations and escalating anything outstanding.
• Accuracy and control - keeping accurate accounting records, making sure transactions are correctly coded, and querying anything that doesn't look right.

About You

What we're looking for:

• Ideally at least 2 years' experience in a finance or accounts environment - for example as a purchase ledger clerk or accounts assistant.
• A methodical and organised approach, with good attention to detail and accuracy.
• Good working knowledge of Excel and Microsoft Office, and confidence handling large volumes of data.
• Clear communication skills and the ability to work to weekly and month‑end deadlines.
• A willingness to learn, take ownership of your work, and question anything that doesn't look right.

Also useful, but not essential

• Experience in construction, recruitment or another high-volume, multi-company business.
• Exposure to Dynamics 365 Business Central or Evolution M - training will be provided either way.
• Study towards, or completion of, an accounting qualification such as AAT.

Working Arrangements

Office based at our Potters Bar head office, Monday to Friday, 08:00-17:00. Annual leave: 24 days + 8 bank holidays + 3 days Christmas shutdown.

This is a great opportunity to join an established finance team where you'll have the chance to build on your existing experience and develop a broader understanding of finance across the group.

You'll be joining a supportive team with established processes, varied responsibilities and full training on our systems. If you're organised, accurate and looking for a role where you can take ownership and continue to develop, we'd love to hear from you.
