Before you create your stock items, it is a good idea to decide on a naming/numbering scheme that will work best for you and your business. Stock numbers can be any combination of numbers and/or letters.

In many cases, the manufacturer will provide a UPC for stock items. This is an easy and efficient way to track inventory stock items. Because different vendors of the same item might use different UPCs, you can use stock item aliases to reflect that items with multiple UPCs are the same item (see Setting Up Additional Stock Item Identifiers).
