Buy & Sell

Buy & Sell is the desktop app for the Buy & Sell point of sale. It opens your shop's POS in its own window and adds what a browser can't do on a till.

What it adds

• Receipt printing – a local print bridge sends receipts straight to ESC/POS printers on your network (port 9100) or over USB, without print dialogs.
• Cash drawer – opens the drawer connected to the receipt printer.
• No double receipts – repeated print requests for the same order are printed once.
• Customer display – shows the order on a second screen.
• Invoices – preview and print PDF invoices.
• Kiosk mode and start at login – the till opens straight into the POS.
• Admin PIN – settings are protected by a PIN.
• Connection badge – shows the response time of your POS server at a glance.

Requirements

A Buy & Sell account (https://buyandsell.bt). The app connects to your shop's address, for example https://yourshop.buyandsell.bt.

USB receipt printers

For printers connected by USB (usb:/dev/usb/lp0), allow access once:

 sudo snap connect buyandsell:raw-usb
