Job description

Location: Central London (Hybrid – 3 days in the office)

Contract: Permanent

The Opportunity

We’re working with a PE-backed B2B financial data and intelligence business that is going through an exciting period of growth and transformation.

This isn't a traditional invoice-processing role. The finance function is currently evolving, with new systems, automation and process improvements being introduced on an ongoing basis. You'll need to be comfortable working in a hands‑on environment where processes are still being developed, and be someone who enjoys finding better ways of doing things.

Reporting to the Financial Controller and working closely with the Head of Finance and CFO, you'll take ownership of accounts payable and receivable across two trading entities.

Your responsibilities will include:

• Managing AP and AR processes end-to-end, ensuring accuracy and timely completion.
• Overseeing approximately 100–150 AP invoices and up to 200 AR invoices per month.
• Reviewing, approving, matching and posting invoices into Sage Intacct.
• Raising and sending sales invoices to clients and managing adjustments and queries.
• Taking ownership of the finance mailbox, ensuring queries and responses are managed efficiently.
• Setting up and managing approval matrices and helping improve finance processes.
• Supporting the ongoing automation and improvement of AP and AR processes as the finance function evolves.
• Supporting bank reconciliations, balance sheet reconciliations and cash book entries as automation continues to develop.
• Assisting with revenue recognition across SaaS annual contracts and event-based cost bucketing.
• Supporting multinational tax checking and maintaining strong financial controls.
• Working across Sage Intacct and Salesforce as the wider technology stack continues to evolve.

As the finance function maturing, this role will expand beyond AP and AR, providing broader exposure to the Financial Controller and wider finance team.

About You

We're looking for someone with approximately 3-4 years of experience in a broad finance or accounts role.

You might be an Accounts Assistant, Assistant Accountant, Finance Assistant or similar, with experience across AP, AR or both.

You'll ideally have:

• Experience managing accounts payable and/or accounts receivable processes.
• Strong attention to detail and experience with reconciliations.
• Confidence working with finance systems and ERP platforms.
• A proactive, hands‑on approach and the ability to take ownership.
• An interest in automation, AI and improving the way finance processes work.
• The ability to work independently in a fast‑paced, evolving environment.
• Experience with Sage Intacct would be beneficial but is not essential.

This is a great opportunity to join a growing business at an early stage of its finance transformation. You'll have genuine visibility across the organisation, work closely with senior finance leadership and play an important role in shaping processes and systems rather than simply following established procedures.

If you're someone who enjoys taking ownership, solving problems and making things work better, we'd love to hear from you.
