About

We make simple, honest spreadsheet tools for small sellers and the self-employed.

Most small shops don't know their real profit. Platform fees, payment processing, ads, shipping and materials all chip away at every sale, and the numbers live in five different places. Our tools pull them into one place so you can see what's actually working.

How we build them

  • Pay once, keep it forever. No subscriptions, no logins, no apps to connect.
  • Works where you already work. Microsoft Excel, Google Sheets and Apple Numbers.
  • Checked, not guessed. Every formula is tested against a full year of sample data, and any rates we use are listed with their sources.
  • Plain English. Clear instructions, colour-coded cells, and a quick-start guide in every download.
