SKU

Stock Keeping Unit — a unique identifier for each variant of each product in your catalog. A black small T-shirt and a black medium are two different SKUs.

A SKU (Stock Keeping Unit) is a unique identifier for each variant of each product in your catalog. A single "T-shirt" listing with 3 colors and 4 sizes is actually 12 SKUs — each a unique combination tracked separately for inventory, pricing, and reporting.

SKU count is a real operational lever. A store with 5 SKUs is fundamentally different to operate than one with 500: support complexity, creative complexity, and forecasting complexity scale non-linearly with SKU count. The operators who scale cleanest are usually the ones with ruthless SKU discipline — 20-50 active SKUs, with clear ABC inventory tiers, not 500 drop-shipped listings that never sell.
