Why it works
Small businesses fall behind on books they cannot afford a full bookkeeper for, and categorisation is high-volume pattern work - but the liability for getting it wrong keeps a named human in the loop.
How it makes money
Monthly retainer
How to start
- Get comfortable in one ledger - QuickBooks Online covers most small-business work.
- Choose a trade with predictable transaction shapes: trades contractors, salons, single-site cafes.
- Write the chart of accounts and categorisation rules for that trade before touching AI.
- Use ChatGPT to categorise bank feed lines in bulk against those rules, not against its own judgement.
- Review every categorisation. An AI-miscoded expense is a filing error with your name on it.
- Build a month-end checklist: reconcile, chase missing receipts, flag anything unusual to the owner.
- Do one month free for a business with a messy ledger and show the before-and-after.
- Price monthly by transaction volume, not by hours, and cap the volume in the agreement.
- Be explicit in writing that you do not give tax advice unless you hold the qualification.
- Add quarter-end reporting once the monthly work is running smoothly.
- Carry professional indemnity cover before taking the second client.
