Stock Keeping Unit (SKU)

Also known as: SKU

A stock keeping unit (SKU) is a unique identifier for a distinct product or item, used to track inventory and sales precisely.

Each SKU represents a specific variant of a product — a particular size, colour, pack or specification — so it can be counted, ordered and priced individually. SKUs are the granular building blocks of catalogues and inventory systems, distinct from broader product groupings.

The breadth of a catalogue is often measured in SKUs. A large marketplace carries an enormous range — Lapasar's platform lists more than 2 million SKUs across categories — so buyers can find precise items rather than approximate substitutes.
