The invoice that writes itself

This one doesn’t use AI at all. It doesn’t need to.

I tag my calendar entries with client codes like @KK or @AA-consulting. At the end of the month, the tool reads my calendar, calculates the hours, generates a PDF invoice with the correct rates and exchange conversions, and files it. If a client pays in euros, it pulls the RBA exchange rate so the ATO gets what it needs when tax time comes.

The receipts can wait

Every quarter I used to lose an entire afternoon to the same ritual. Dig through emails, download PDFs, open bank statements, match invoices to transactions, sort business from personal, convert USD and EUR to AUD, file everything into folders my tax person understands. It’s the kind of work that makes you question your life choices.

I run a small operation. Invoices arrive by email in three currencies. Receipts come as PDFs, photos of paper, forwarded attachments. Some are from Anthropic in US dollars, some from German clients in euros, some from the local office supply shop in AUD. Each one needs to be read, categorised, and filed in a way that survives an ATO audit.
