Why SKUs Are Important In Your E-Commerce StoreAn SKU is an identification code that is utilized to track a product for inventory and sales purposes. It may also incorporate some details about the item, such as color, size, and other variations. Even if you sell the same product as another seller, SKUs are unique to each product. An SKU makes a difference in numerous ways, such as by effectively categorizing items, measuring inventory levels, purchasing accurate items, and helping make communication smooth and efficient between you, the vendors, and your customers.
