A SKU (Stock Keeping Unit) is a unique alphanumeric code assigned to a product to help businesses identify, track, and manage inventory efficiently. SKUs are essential in retail, e-commerce, and warehousing, enabling companies to monitor stock levels, sales trends, and product variations such as size, color, or model.

Each SKU is custom-designed by the business and typically includes a combination of letters and numbers that describe key attributes of the item. For example, a black men’s t-shirt, size large, might have an SKU like TSH-BLK-M-L.

SKUs are used internally by businesses and are different from barcodes or UPCs (Universal Product Codes), which are standardized and used across retailers. With a well-structured SKU system, companies can:

• Quickly locate and restock products

• Analyze sales performance per item

• Improve inventory accuracy

• Reduce errors in order fulfillment

In addition, SKUs help streamline operations such as reordering, pricing, and reporting, especially when integrated into point-of-sale (POS) or inventory management systems.

In summary, SKUs play a vital role in inventory control and operational efficiency, allowing businesses to manage products with precision, enhance customer service, and make data-driven inventory decisions.
