Finance Accountant (SaaS) in London

£50k – £60k + equity UK | Full-time | Remote-first

We’re hiring a Finance Accountant to join our small finance team. You’ll report to the Associate Finance Director and take real ownership of the day-to-day accounting work that keeps zeroheight running accurately – from month‑end close and SaaS billing to global tax compliance. This role is ideal for someone who is detail‑oriented, proactive in improving processes, and keen to build their experience in a fast‑paced SaaS environment.

Your impact:

• You’ll be responsible for running the core accounting operations day to day: delivering a reliable monthly close, ensuring billing runs smoothly, meeting tax obligations, and managing the finance inbox.
• There is scope to improve existing processes, particularly as we explore automation and AI tools within finance.

Why should you join us in particular:

• You’ll have real ownership of day‑to‑day accounting – working closely with the Associate Finance Director, but with the trust and autonomy to run your areas independently.
• Real scope to improve how things work – we’re actively investing in automation and AI tools in finance.
• A SaaS company that’s growing, profitable, and genuinely trusted by some of the world’s best product teams.
• Fully remote, flexible, and set up to let you do your best work.

Your day‑to‑day:

• Own month‑end close: bank reconciliations, journal postings, prepayments and accruals, fixed assets, balance sheet reconciliations, and variance analysis.
• Maintain cost reporting and financial controls, overseeing accounts payable to ensure invoices are coded correctly, approvals are followed, and suppliers are paid on time.
• Oversee accounts receivable, ensuring invoicing, collections, and cash allocation are accurate and on track.
• Assisting with Annual audit for the UK entity.
• Own the accounting inbox and act as a key point of contact for internal and external queries.
• Own global sales tax compliance and handle international tax issues (withholding, compliance filings, customer tax queries).
• Manage UK VAT returns and support UK PSA and P11D reporting.
• Own Stripe configuration – product catalogue, subscription management, enterprise invoicing workflows, and discrepancy resolution.
• Support group reporting to our US parent, including intercompany accounting and transfer pricing.

Essential Skills:

• 4+ years of experience in a finance or accounting role, ideally within a SaaS or technology business.
• Strong understanding of accounting principles and financial reporting, with hands‑on Xero experience.
• Strong Excel skills, including the ability to manipulate data and build clear, reliable reports.
• Fully qualified accountant (e.g. ACCA, CIMA, ACA).
• Working knowledge of UK VAT, global sales tax, and international tax concepts (SaaS context preferred).
• Comfortable with ambiguity – proactive in finding answers and solving problems.
• Able to travel to our London hub at least once per quarter.

Bonus Skills:

• Experience with Stripe and HubSpot, including billing, invoicing, and reconciliation.
• Exposure to group structures and intercompany accounting.
• Demonstrated interest in automation or AI tools to improve finance processes.
