When a payment has successfully been made, your cash register will show a small window with payment information such as receipt number, total amount paid, payment method (cash, card, giftcard, invoice, etc.), and email address for digital receipt.
You can hide this window and have only a small pop up at the bottom right every time you finish a transaction. Please follow these steps:
Open the left-side menu by clicking on the three stripe lines on the top left corner
Click on Settings and select "TRANSACTIONS" tab
Enable the "Do not show payment success info"
Now every time you complete a transaction, you'll get a small pop up window on the bottom right confirming that the transaction is completed.
