Always-On Bookkeeper for UK Sole Traders
A subscription service where an AI agent logs into your cloud accounting software daily, categorizes every bank transaction against the attached invoice, and files your quarterly VAT return to HMRC with a human accountant reviewing edge cases.
UK sole traders and micro-business owners currently paying an accountant £750-2,100 per quarter for routine VAT filing
- Direct read/write access to Xero, QuickBooks, and FreeAgent to categorize transactions using bank feed + PDF invoice context
- Quarterly VAT return auto-prepared and submitted to HMRC Making Tax Digital, with the one-off share-capital mistakes routed to a human reviewer
