Stop fumbling with invoice templates every time a client needs to pay you.
Feed in your project details, rates, and client info — in any format — and get a professional, print-ready HTML invoice, a CSV line item log for your books, and pre-written payment reminder emails for when they're late. Handles all the math automatically.
With the Invoice Generator skill.
Your input. Your output.

The difference is night and day.
- Every invoice starts with a blank template — you re-enter client info, calculate totals with a calculator, and pray you don't forget the tax
- FreshBooks is $15/month for something you use twice a month, and Excel invoice templates look like they were made in 1995
- You spend more time formatting invoices than you did on some of the actual work you're billing for
- Professional HTML invoice with all math calculated automatically — looks like enterprise billing software, costs $30 one-time
- Drop in project notes and client details in any format, get back a formatted invoice ready to print or email
- Payment reminder templates included so you never have to write awkward 'hey, you owe me money' emails again
