To have items in the system you will need to add them on the POS Items page under setup. You can enter an item in to tell by either scanning it with a barcode reader or searching it by name.
To search by name simply type in the name and results that include that name will appear below.
Once selected the screen will update with the item chosen. You will now be able to update the quantity of the item as well as add in any discount if you so desire.
After you have the items you need simply select method of payment and click Complete Sale.
You will then receive a message notifying you if the customer gets any change back from transaction. After that the receipt will load on a separate window allowing you to print it for the customer.
