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.
It tracks what’s been paid, what’s outstanding, what’s overdue. It generates quarterly tax summaries. It backs itself up to iCloud every time I close it.
No dashboard. No subscription. No login. Just a command line interface I run from Terminal when I need to send an invoice, which takes about thirty seconds.
I built it because every invoicing SaaS I tried did too much. They wanted to be my CRM, my project manager, my accountant. I just wanted to turn hours into a PDF and know when I’ve been paid. Das Wenige. The tool that does one thing and doesn’t ask for your credit card.
It pairs with the finance tool I built for incoming receipts. Between the two, the entire money side of running a small business runs itself.
