What is SKU in Products? Key Tips for Optimizing Inventory

What is SKU in Products?

Definition of SKU

A Stock Keeping Unit (SKU) is a unique identifier assigned to each product or item in a company's inventory. This identifier is used to track products and manage inventory efficiently. SKUs are alphanumeric and can include letters, numbers, and even dashes to distinguish one product from another. They are vital for inventory management, enabling businesses to keep precise records of product details, quantities, and locations.

Differences between SKU and UPC

While both SKUs and Universal Product Codes (UPC) are used for product identification, they serve different purposes. SKUs are internal codes created by businesses to manage inventory, whereas UPCs are standardized barcodes used globally to identify products at the point of sale. UPCs are typically provided by manufacturers and remain constant across all retailers, while SKUs are unique to each business and can be customized to suit specific needs.

Importance of SKUs in Inventory Management

SKUs are crucial for effective inventory management. They allow businesses to:

• Track product movement accurately.
