A Seller Stock Keeping Unit is an identifier assigned by a merchant to uniquely track their products within their own inventory management system and on the Amazon marketplace. It is a string of alphanumeric characters, typically chosen to reflect properties of the item such as size, color, condition, or supplier. For example, a seller might assign “TSHIRT-RED-L” to a red t-shirt, size large.
This identifier is crucial for internal organization and efficient order fulfillment. It enables merchants to quickly locate and manage inventory, reducing errors and improving accuracy in shipping. Using this system streamlines warehouse operations, particularly when dealing with a large number of diverse products. The concept of inventory tracking using unique identifiers has been employed in retail and warehousing for decades, with online marketplaces adapting this practice to the digital environment.
