A new inventory utility has been added to WinSale that can use the sales and purchase order history to remove dead inventory from your system. Dead Inventory is defined as having an item number with zero quantity on hand and no history of sales or reorders back to the ending date that you define. The default settings for the ending date are the first five years of your use of WinSale. This utility lets you create an Excel spreadsheet for the items it is deleting. Also, this utility can archive the inventory instead of deleting it totally. If you really want to clean the house there is even an option to delete the inventory from the archive file as well.
In the future look to this utility to control the winnowing out of the customers that have not patronized your stores for several years or even decades.
