Built by an accountant who got tired of scanning letters.

Every morning at the firm, the same routine. Open the post pile, read through each letter to work out which client it belongs to, walk to the scanner, scan them one at a time, save each PDF, write an email, attach the file, send it. For a North London practice managing over 200 registered office clients, this process consumed hours every single week.

The compliance risk was real too. Miss one HMRC penalty notice buried in a stack of 50 letters and a client gets a fine they shouldn't have. Scan a document to the wrong client and you've got a data breach. The manual process wasn't just slow — it was fragile.

I looked for a tool that solved this specific problem. Document management systems handle invoices and receipts, not statutory correspondence. Virtual mailroom services handle scanning but not classification. Nothing combined automatic document reading, intelligent sorting, and practice-level client management into a single workflow built specifically for firms processing registered office mail.

So I built one. ComplyPost is the software I wished existed when I started that morning mail routine. Every feature exists because it solves a problem I encountered personally — not because it looks good on a feature list. The mission is simple: save every accountancy and legal firm managing registered office clients hours of manual work every week.
