SKU (stock keeping unit)
A SKU is a code a store gives each product variant it stocks, so every item — down to its size and colour — can be counted, found and reordered.
A SKU is your own code, not a universal one: two stores can sell the same item under different SKUs. A good SKU is short, readable and follows a pattern, such as TSHIRT-BLK-M for a black T-shirt in medium.
Why it matters
- It tells you exactly which item to pick and pack, even when two variants look alike.
- It makes stock counts, reorders and spreadsheets reliable.
- It stays the same when you rename a product.
Example
A shirt sold in three colours and four sizes has twelve variants, so twelve SKUs.
In Soooks
Every variant has its own SKU field, next to its barcode, price and stock.

Product variant
A variant is one specific version of a product — a particular size, colour or material — with its own price, stock and often its own photo.

Inventory
Inventory is the stock a store has to sell: how many of each variant are on hand, where they are, and how that changes as orders and deliveries come in.

Barcode (GTIN, EAN, UPC)
A barcode is a scannable number on a product's packaging. Global ones (GTIN, EAN or UPC) identify the same product in every store that sells it.
