SKU (Stock Keeping Unit)
SKU (Stock Keeping Unit): A unique identifier for each distinct product and its variants.
What SKU means
SKU stands for stock keeping unit. It is created by the business, unlike a manufacturer barcode that may come from outside the business.
SKU vs barcode
A SKU is the internal identifier. A barcode is a machine-readable representation that can point to a SKU or another item code.
Good SKU habits
Keep SKUs unique, consistent, and stable. Avoid encoding too much information that may change, such as supplier or location.
