Accounts Payable Assistant

What is the job?

Behind every growing business is a Finance team making sure everything runs like clockwork.

We are looking for an Accounts Payable Assistant to join our growing Finance team and become the go-to person for keeping our supplier payments, invoices, and financial processes running smoothly.

This is much more than a data-entry role. You will be at the heart of the Finance function, working closely with colleagues across the UK and South Africa to ensure our suppliers are paid on time, our records are accurate, and our business has the foundations it needs to continue scaling.

You will join a collaborative, supportive team that values curiosity, ownership, and continuous improvement. Whether you're chasing down a tricky invoice discrepancy, improving a process, or helping the team hit month-end deadlines, you'll play an important role in the success of the business.

This role is employed through our South African partner, Mindpearl, and works closely with our UK-based teams and stakeholders, aligned to UK working hours.

What will you be doing?

• Taking ownership of the accounts payable process from invoice receipt through to payment

• Processing supplier invoices accurately and efficiently while ensuring appropriate approvals are in place

• Managing supplier relationships and responding to queries professionally and promptly

• Reconciling supplier statements and resolving discrepancies before they become problems

• Supporting weekly and monthly payment runs to ensure suppliers are paid accurately and on time

• Processing employee expenses and helping maintain robust financial controls

• Assisting with bank, credit card, and supplier reconciliations

• Supporting month-end activities and helping the team deliver accurate financial reporting

• Working with colleagues across the business to improve processes and find smarter ways of working

• Helping create a finance function that is efficient, scalable, and ready for continued growth

What do you need?

• Previous experience in Accounts Payable, Finance Administration, Bookkeeping, or a similar finance role

• Excellent attention to detail and a genuine passion for accuracy

• Strong organisational skills and the ability to manage multiple priorities

• Confidence working with numbers, spreadsheets, and finance systems

• Great communication skills and a customer-service mindset when working with suppliers and internal stakeholders

• A proactive approach and willingness to roll up your sleeves when needed

• The ability to thrive in a fast-paced environment where no two days are quite the same

Nice to have

• Experience using ADP or similar accounting software

• Experience supporting UK-based businesses

• Exposure to month-end processes and reconciliations

• Previous experience in a scale-up or rapidly growing organisation
