SKU

Stock Keeping Unit

Definition

A unique code assigned to each individual product or product variant in your inventory for tracking and management purposes.

Why it matters

SKUs keep your inventory organised. Without them, managing multiple products, sizes, and colours becomes chaotic, especially as you scale.

Example

You sell a silk dress in sizes 8, 10, 12, and in black, white, and red. Each size/colour combination is a separate SKU, 12 SKUs total for one product.
