Accounts Assistant
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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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.

Your very own career expert that helps elevate your application to the next level.
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.
Why join us?
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.
