A modern POS (point-of-sale) system does much more than ring up sales. It tracks stock, shows your best-selling items, manages staff, prints proper receipts and connects to card payments. Choosing the right one saves hours every week. Choosing the wrong one is painful to undo.
What a POS system does
- Records every sale and takes payment (cash, card, phone wallets)
- Prints or emails receipts
- Tracks inventory and warns you when stock is low
- Shows sales reports by product, staff member, day and hour
- Manages staff logins and permissions
- Stores customer details and loyalty points (on some systems)
