POS terminal frozen or cannot process sales
First steps when a point-of-sale terminal stops responding or cannot complete sales.
Reviewed 06 Nov 2026
Try these steps
- 1 If a sale is in progress, note the amount and items before restarting anything.
- 2 Close the POS application properly if possible and open it again.
- 3 Restart the POS terminal using its normal shutdown, then switch it on again.
- 4 Check the network cable and that other terminals in the shop can process sales. If none can, the store network or the POS server may be down.
- 5 Check that the receipt printer, scanner and card terminal are powered on and connected.
- 6 Never share card details or PINs; do not process card payments manually.
Before you start
Work through the steps in order and stop as soon as the problem is fixed. Never share passwords or verification codes with anyone.
When to contact support
If no terminal can sell, call support immediately and open a Critical ticket with the store name.
