POS & Sales

POS Checkout Screen Freezing

Problem: The checkout/billing screen stops responding while scanning items or applying a discount.

Possible Causes

  • Too many items held in an unfinished cart for too long.

  • Barcode scanner sending duplicate/garbled input.

  • Browser tab has been open for several hours without a refresh.

  • Slow internet connection during a price sync.

Solution

  1. Refresh the POS tab — held cart items are auto-saved as a draft.

  2. Rescan the last few items individually instead of using the scanner in rapid-fire mode.

  3. Close unused browser tabs to free up memory.

  4. Check Settings → System Requirements if this happens repeatedly on the same device.

Error Message

Resolution

Cart not responding to scans

Refresh the tab; the draft cart is restored automatically.

"Sync in progress" stuck

Wait 10 seconds — if it persists, check your internet connection.

Tip: Restart the POS terminal at the start of every shift rather than leaving the tab open for days.

Frequently Asked Questions

Will I lose the cart if I refresh?

No. ScomsERP Retail POS auto-saves an in-progress cart as a draft every few seconds, so refreshing restores it.
