Good to know
A void is all or nothing and can't be undone. To give back only some items, use Refund instead.
Void sale only works on a sale that hasn't been refunded at all, from the register session that's open now. After any refund, or once that drawer has been closed, use Refund instead.
Like a refund, a void needs an open register drawer and an internet connection, and your role must be allowed to issue refunds and voids.
1. Void the whole sale
Click Void sale on the receipt, choose a reason, and confirm. The card payment, if any, is reversed to the card shown.
