# Quick Posting
To use the Quick Posting screen, you must first define a product or service.\
You can create a product definition by clicking the pencil icon on the screen.
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.
