What you'll have
Gmail filters that label invoices and receipts, a Zap that logs each one to a spreadsheet with an AI-suggested category, and a monthly review in your accounting software.
Who pays for it: You, first. Once it works, you can set it up for other freelancers as a small service.

Build a Zap from that label
Use a new labeled email as the trigger and add actions, mapping fields from the email so each run uses its own data.

Add an AI step to summarise and categorise
Have an AI step pull out vendor, amount, date and a suggested category. Treat it as a suggestion and check amounts against the attachment.
Our advice. No specific menus involved.
Reconcile monthly in your accounting software
Upload receipts and match transactions in QuickBooks, Xero or Wave.
Not verified in the docs. The QuickBooks receipt-upload article returned an error when we checked on 20 Oct 2026, so this step's menu names aren't verified. QuickBooks Online help
Common mistakes
- Trusting AI-extracted amounts without checking.
- Sending financial documents to tools a client hasn't approved.
- Treating AI categories as tax advice.
Rights and terms check
Nothing to sell here, but you're handling financial data. Check each tool's data terms and keep access minimal.
