If a saved product is sold, clicking on the product once will create a check (order slip) on the right side of the screen.

The payment of the sold product can be processed as a cash or credit card transaction by clicking the corresponding button, and it will be recorded as a direct sale to the cashier.\
If the sold product is to be posted to a room, click the “Room” button and select the guest. This way, the selected products will be posted to the folio.
