What is a POS?
A POS, or point of sale, is what we used to call the cash register. Instead of that old lump of metal, shops now run a piece of software — and that’s the POS.
Careful, because the same three letters get used for the card terminal you take payments on. Here we use “POS” only for the software that runs a bricks-and-mortar shop.
In the broad sense, a POS also takes in the hardware: the computer, the barcode scanner, the receipt printer, the cash drawer and the card terminal.
What is a point of sale system?
A point of sale system is exactly the same thing as a POS — POS is simply the abbreviation. Some people say “till system” or “EPOS”. It all comes to the same.
What’s the difference between a POS and a cash register?
Modern POS software does everything a cash register did and a great deal more: it tracks stock, manages customers, produces sales reports, issues proper invoices and syncs with an online shop.
