A cash register can do the most important till functions a retailer would need. It accepts cash, card and cheques payments, and if you get one with a barcode scanner, you can even scan the barcodes of products you have saved on the cash register. The popular Casio registers can have up to 2000 products saved, although the cheaper SE-G1 model only saves up to 999 products. These can be divided into product categories.
POS systems typically allow you to save unlimited products, categories, options (e.g. size, colour) and pictures to display on the POS screen. This is much more adaptable since it can be changed any time from the screen, as opposed to a cash register that requires you to save everything on an SD card.
Refunds, discounts and adding tax is possible on a cash register and POS system. You can use employee IDs on a cash register, but POS systems allow you to set individual permissions for each staff account and track shifts and sales by employee as well.
Cashing-up reports with sales totals by department and tender – called Z reports – can be printed on cash registers, as can anytime sales reports called X reports. Receipts can be customised on a cash register, but only parts of the text can be edited. You can usually add company logo on a POS system receipt, plus any text you want. Furthermore, POS systems allow you to view and print sales reports in various formats, focusing on the things you need for accounting.
