Stock Keeping Units or SKUs are unique identifiers assigned to specific products. These SKUs are used for inventory tracking purposes. In order to manage your inventory successfully, make sure that your SKUs have meaningful naming patterns.

Maintaining consistent, meaningful SKUs will make managing your inventory a lot easier. This is especially true for retailers selling on multiple channels. If you sell on your own web store in addition to eBay or Amazon, you are very likely to have different product titles for the same product on each of these sales channels.
