Summary: Cancel (void) an invoice from Invoice Management in Qashier POS. Any payment already taken for the invoice is voided with it.
Applies to: All markets · Qashier POS · Invoice Management add-on · staff who know the Terminal PIN.
Before you start
Invoice Management must be turned on for your store. If you don't see Invoice Management on the POS home screen, see How to Add Features and Manage Your Plan in Qashier Marketplace (QashierHQ).
You need the Terminal PIN to cancel an invoice. See How to View or Change Your Terminal PIN in QashierHQ.
Cancel an invoice
On the home screen, tap Invoice Management. You can also open it from the menu on the POS & Payment screen.
If asked, enter your staff PIN and tap Confirm.
The list shows today's invoices. To find an older invoice, tap the calendar icon at the top left and choose the date range it was created in (up to one year back). You can also tap Filter to show only Unpaid, Partially Paid, Fully Paid or Cancelled invoices.
Select the invoice you want to cancel from the list on the left. If the list is long, search by invoice number, the customer's name or phone number, or a product name.
Tap Cancel Invoice at the bottom right.
On Please Confirm Cancelling, tap Yes.
Enter the Terminal PIN and tap Confirm.
In Void Note, type the reason for cancelling. This field is required.
Tap OK to cancel the invoice.
What happens when you cancel
The invoice shows as Cancelled in the list, with your reason under Cancel Notes/Reason.
Any deposit or full payment already taken for the invoice is voided, including card payments. Cash paid is taken off the cash drawer record, and customer credit used is returned to the customer.
If you track inventory, the POS asks "Would you like to add back the inventory of the voided items?". Tap Yes to return the items to stock.
If you use Treats, the customer's points or credit from the invoice are reversed.
You can also start from the payment: if you void a payment linked to an invoice in Transaction Record, the POS asks whether you want to cancel the invoice as well. See How to Void or Refund a Transaction in Qashier POS.
If something goes wrong
What you see | Cause | What to do |
"Unable to cancel the invoice because one of the transactions cannot be voided." | A payment linked to the invoice can't be voided. | Check the payment in Transaction Record (see How to Void or Refund a Transaction in Qashier POS), then try again. If it still fails, contact Qashier support. |
Nothing happens after you tap Yes | No Terminal PIN is set on this terminal. | Set a Terminal PIN (see How to View or Change Your Terminal PIN in QashierHQ), then try again. |
The invoice is still not cancelled after you tap OK | The void reason was left empty. | Repeat the steps and type a reason in Void Note. |
"Invalid PIN." | The Terminal PIN was wrong. | Ask your manager for the Terminal PIN and try again. |
You can't find the invoice | It was created outside the selected date range, or a filter is on. | Change the date range and set Filter back to show all invoices. |
