Access this menu option from the main Menu-->Order Processing-->Maintain Cart.
The Maintain Cart feature allows you to quickly make certain changes to or delete Products/Services that are in a cart but have not been checked out.
Maintain cart is a great way to clean up items in the cart. For example, if the application preference is set to Automatically Add a Boarding Cancellation fee, and you do not want to charge those fees, you can delete those fees from the cart here. If you are efficiently signing pets in and out each day, maintain cart should reflect those pets that are currently in your facility, signed in and on your dashboard.
