From the Dashboard go to Point Of Sale >> View Orders, Select the time frame (in this example it is year to date)
For quick reference on POS Items you can also see them on the 'Payment Screens'. The transaction ID will say "Point of Sale".
On the Transactions report Point of Sale items are shown, however they are displayed in the categories that you set up in the POS system. In this example "Food & Drink".
TIP: if you need quick access to Transaction Level POS information you may want to give your POS categories a name like 'POS - Food & Drink' or 'POS - Swim Class'. This way you can tell which ones come from your POS system rather than your products.
