What is an SKU (Stock Keeping Unit)?

An SKU (Stock Keeping Unit) is a unique identifier assigned to a product for inventory tracking purposes. It typically corresponds to a distinct item reference, including specific product characteristics when relevant (such as size, color, or model).

SKUs enable precise inventory management: each SKU represents a separately managed stock unit, making it easier to track stock levels, sales, and replenishment for every product variant.
