Buy & sell things with bitcoin
Sell from a page you own. The money goes straight to you. Every sale gets a receipt anyone can check.
What stays true
-
Your data assets
Keep one inventory of what you own, real and digital. Manage it privately, and show publicly only what you choose to share.
-
Peer to peer bitcoin
Sell anything in your inventory straight to the person who wants it. They pay your own bitcoin address, with no one holding the money in between.
-
The transaction is the receipt
A bitcoin sale is recorded on the chain the moment it is paid. That one record is the receipt for you and your customer, and anyone can check it.
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.

I have a counter
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.
