Ringing a Cash Transaction
As you add items to a receipt, the total for the sale will tally at the bottom. When you're finished adding items tap the button.
If the customer gives you more cash than the total, use a pre-set button showing common tender denominations or type the cash amount into the Cash field and tap Tender. The change due is shown on this screen and the receipt screen.
Press tender to complete the transaction and go to the receipt screen.
