Point of Sale opens either from the top ribbon or from the reservation form.

It gives you multiple options:

- sell item anonymously 

- Sell item to the particular guest. If we want to sell an item to someone who is our guest by searching his name in POS window, such sale can only be performed to a guest that has CHECKED IN.

- let the guest pay later

If the guest wants to pay with a higher nominal, the system can show you the change that has to be given. It can be done by putting the amount that the guests gives in Pay Now field:

In this case the transaction will be normally saved in Accounts & Transactions section. The change section it's only for the receptionist's information.
