If a sale won’t finalise, it’s usually the payment not covering the total, a closed shift/register, or (on the web POS) a connection issue. Your cart isn’t lost — work through these.
Step by step
- Check the payment covers the totalMake sure the tendered amount(s) equal the total, or that any unpaid balance is being recorded as a customer due with a customer attached.
- Check the shift/register is openA sale needs an open shift on that register. Open the shift — see shifts & cash drawer.
- Check the connection (web POS)The browser POS needs a connection; the dedicated app completes offline. If online is flaky, use the app.
- Retry or holdRetry the payment; if you need to serve the next customer, hold the sale and come back to it.
