What SellyPOS does

Printers, scanners and screens that work with your till

Your till needs a receipt printer and a barcode scanner, and many shops add a screen that faces the customer. SellyPOS finds your printer for you and tests it before you save it. It can also show the bill to your customer, and print labels with a promotion price or a clothes size.

Receipt printers and the other devices, set up once and ready for the counter.

Every shop meets the same hardware at the counter: a receipt printer, a scanner and a customer who wants to see the bill. This page shows how SellyPOS handles each one, from the first plug-in to the last sale of the day.

You can set up a printer yourself. Plug it in with a USB cable or pair it over Bluetooth, and SellyPOS lists it, so you do not need to type an address. Print a test page before you save, and you will know it works before the first customer arrives.

Read the sections in order when you set up a new till, or jump to the one you need. The printer steps and the customer screen settings are both on the Hardware page.

  3. Check your scanner and print barcode labels

    Test the scanner first, so you see what it sends before the first sale. Labels with the right barcode and price keep the shelf and the till in step.

  4. Print promotion prices, and full or main names on labels

    A shelf label can show the regular price crossed out, the promotion price, the percentage off and the last day. Each label design also chooses whether it prints the full product name or only the main name.

  5. Print only the size code on clothes labels

    A clothes label can print only its short size code, such as M or XL. Each size or colour has one short code of up to four characters, and the form fills it in for you.

  6. Show a phone's codes and warranty on receipts and invoices

    A phone's IMEI numbers, serial number and warranty end dates can print on the receipt and on the A4 invoice. You choose which phone details print, and only those will show.

Once the printer prints the right receipt and the scanner reads the right code, the counter can get on with the queue. Set up one printer, sell a few test items, and see how it feels before a busy morning.
