Retail Items can be sold once the Inventory ability has been set up. If the office has a barcode scanner, simply open the New Charge window and scan the item. If you do not have a scanner, you can click the search button to manually select the Inventory code from your fee schedule.
Items can be marked as Consumed through the New Charge window as well. Simply click on the Items tab and search for the item that was consumed. If an item is always consumed with a specific procedure, you can watch Inventory 4 from the Inventory Video Series to see how to tie Consumed Items to fees.
