You own the page
Your domain, your HTML. Anyone can read how it works in View Source.
The money goes to you
Bitcoin goes to your own address. Card sales go to your own Stripe account. Qart takes no percentage of a sale.
The receipt is permanent
Every sale can have a receipt with its own address that anyone can check.
Start where you are
Each tool works by itself. Nobody has to use them all.
I have a website
A button, or a pay link
Add a buy button to any page, or share a link that is an invoice. It works on plain HTML, Jekyll, or anything that lets you paste markup.

A till, receipts and books
A menu, a cart and a QR code on a tablet or phone. Every sale lands in a journal your accountant can read.
