Reporting directly to our Financial Controller, you won't be assisting someone else's process. You'll own a domain outright, and your Controller will review your work rather than rebuild it.This is a deliberately designed 24-hour role. Not a full-time job squeezed into part-time pay, and not a stopgap—a permanent, well-organised position for someone who wants to do one thing properly rather than five things partially.What You'll DoOwn accounts receivable end-to-end—customer billing, contract invoicing, credit management, and the AR aging overview.Run collections independently, following up past-due balances with a friendly, professional approach and resolving billing queries yourself.Manage the accounts payable pipeline—intake, approval routing, and submission of vendor invoices to our external accountant.Prepare weekly payment batches for approval, maintaining continuous oversight of what's unpaid.Code invoices accurately to the correct general ledger accounts and cost centres.Prepare routine monthly journal entries (accruals and revenue allocations) and perform balance-sheet reconciliations.Review P&L cost and revenue lines to verify correct period allocation.Keep the administration audit-ready as a matter of course, and support the Financial Controller on ad-hoc projects and process improvements.Reports to: Financial ControllerTeam: Finance (working closely with our external accountant, Customer Success, and Sales)Hours: 24 per week—three full days, or spread across four or five.

We read the cover letter first, and we'd love for you to answer three quick questions directly:The full cycle you've owned: Walk us from a customer signing to the accountant filing. Be specific about where your responsibility started and stopped.A balance you recovered: Tell us about a past-due balance you recovered from an unhappy customer. What did you say, and what happened to the relationship afterwards?Managing a 24-hour week: How do you organize your work across 24 hours so that routine deadlines (like month-end or payment runs) are met smoothly without urgent tasks getting stuck on days you're off?Three short paragraphs are plenty. Specific beats polished—we'd rather read one real story than three pages of adjectives.Interview ProcessWe move quickly for the right candidate:Screening Interview – Financial Controller (30 min): Culture fit, ownership experience, motivation, and how a 24-hour week fits your life.Working Interview – Financial Controller (90 min): A live case using real, anonymised material from our own administration, plus a short take-home assignment (capped at 3 hours, and paid).Final Interview – CEO (30 min): Vision alignment, long-term commitment.
