What is a SKU?
SKU stands for Stock Keeping Unit. It is a unique alphanumeric code used to identify individual products and their variations (e.g., size, color) within inventory and fulfillment systems.

By organizing products using SKUs, retailers can automate fulfillment workflows, avoid overselling, and track inventory across multiple locations. everstox supports real-time SKU-level inventory tracking to streamline operations and reduce manual errors.
Example for a SKU
A white T-shirt in size M has the SKU “TSH-WHT-M”. The warehouse uses this code to locate the correct product and ensure that the right item is picked, packed, and shipped.
