Help CenterHelp Center / Point of sale · Concept
The till has no offline mode. A sale whose answer was lost is retried safely, and you can check whether it was saved before you sell again.
The till works only while it is connected. There is no offline mode: scanning, searching, pricing the cart and completing a sale all ask the server.
What the till does protect is the one risky moment: you select Complete sale and the answer never arrives.
Both are kept in this browser only.
The till shows "No connection. The sale was not lost: press Complete again to retry it."
Do not change the cart, the customer, the discounts or the payment fields.
The till sends the same sale with the same id.
Either way the Sale completed window opens with the receipt.
When you select Complete sale with a different cart or different payments, the till first asks the server whether the earlier sale was saved.
The till asks the same question when you reload the page or choose the register again.
A message that names what is wrong, for example "The payment is short by ….", means nothing was sold. So does "The till is busy. Try again in a moment." Fix it and complete the sale again.
Any other error answer, for example "Something went wrong. Please try again.", does not tell you whether the sale was saved.
"This sale is being completed. Wait a moment and try again." means an earlier attempt is still being saved. Wait, then check. If the sale is not there yet, check once more before you complete it again.
After every error answer the till forgets the unanswered sale, so the next Complete sale is sent as a new sale. Check first.
The till has no list of recent sales. Use one of these:
If the sale is there, select Clear the cart and start the next sale. If it is not, complete it again.
A return whose answer was lost is not refunded twice when you select Refund again on the same screen. Do not change the quantities, the reason or the card reference, select Find again or reload the page first.
If you did, select Find and read the Returnable column: items that were already refunded are no longer returnable.
