  • Patent number: 7881987
    Abstract: A purchasing user interface system may include a user interface configured to display various types of inventory, order and purchasing information. The user interface may display item, inventory, order, sales and/or vendor information regarding particular items, or all items, in a current inventory. The user interface may allow user to customize the manner in which the information is displayed. The system may also aid the user in making purchase orders, such as by allowing the user to select items to order as well as the quantities to order and the vendors from which to order the selected items. The system may also allow the user to generate purchase order based on the selected items, amounts and vendors. The purchasing user interface system may allow a user to display, sort, filter, update and otherwise manipulate various inventory, sales, order and vendor information to aid in making meaningful inventory ordering decisions.
