SKU

SKU(Stock Keeping Unit) a code number, typically used as a machine-readable bar code, assigned to a single item of inventory. As part of a system for inventory control, the SKU represents the smallest unit of a product that can be sold from inventory, purchased, or added to inventory.

Managing inventory

Inventory is the quantity of a particular product that is available for sale. Inventory tracking can help avoid selling products that have run out of stock. Mapping between product and sku will only occur if manage stock is enabled.
