What is SKU in e-commerce logistics?

In e-commerce logistics, a SKU (Stock Keeping Unit) is a unique identifier assigned to a specific product or variation of a product. The SKU is used to track and manage inventory in a warehouse or fulfillment center.

A SKU number typically consists of a combination of letters and numbers that are assigned by the seller or the manufacturer. It is used to identify a specific product, such as a specific color or size of a product, and is used in inventory management systems to track the quantity of a product in stock, its location within a warehouse, and its sales history.

SKUs are also used to track products as they move through the supply chain, from the manufacturer to the warehouse and finally to the customer. By using unique SKUs, businesses can quickly and easily identify products, track their movements and manage inventory levels more effectively.

SKU numbers are used in e-commerce logistics to track the inventory of a specific product, check the stock level, and know when to reorder, this is especially important for businesses that sell a large number of products or have many variations of a single product.

SKU numbers are also useful for businesses that sell products through multiple channels, such as a website and physical stores, as it allows them to track inventory levels across all channels and ensure that they have the products in stock to fulfill orders.
