We're looking for someone with proven experience in bookkeeping or finance administration, ideally within an SME or commercial service environment.

You'll be confident managing a range of finance processes and comfortable working independently while also supporting colleagues across the wider business.

You'll bring:

• Previous hands‑on experience across sales ledger, purchase ledger, invoicing and bank reconciliations.
• Experience with credit control and maintaining accurate financial records.
• A good understanding of bookkeeping principles, invoice controls and VAT.
• Strong attention to detail and a high level of accuracy.
• Excellent organisation skills and the ability to manage competing deadlines.
• Confidence using accounting software, Excel, Outlook and digital systems.
• Strong written and verbal communication skills, with a professional telephone manner.
• A discreet and trustworthy approach when handling financial, payroll and customer information.

Desirable: Experience within engineering, construction, facilities, trades or another job‑costed service business, along with knowledge of Sage, Xero, QuickBooks, WIP/job costing or payroll administration. AAT, IAB, ICB or equivalent qualifications would also be advantageous.

What You’ll Be Doing

This role sits at the heart of the company's finance and administration processes, helping to ensure that work is costed accurately, invoiced promptly and financial records remain complete and up to date.

You’ll work closely with the Managing Director and wider management team, as well as operational colleagues, customers, suppliers and the external accountant. You’ll also be responsible for ensuring key finance processes continue smoothly throughout the maternity‑cover period.
