What is a Stock Keeping Unit?

A stock keeping unit, or SKU, is a unique code that is assigned to each product in a shop. This code is used to track inventory and can be used to identify a product when ordering or reordering.

SKUs can be either numeric or alphanumeric, but they must be unique to each product. For example, if a shop sells t-shirts in multiple sizes and colors, each size and color combination would need its own SKU.

Numeric SKUs are typically shorter and easier to remember than alphanumeric SKUs, but they can be harder to manage if a shop sells a large number of products. Alphanumeric SKUs can be any length and can include letters, numbers, and special characters.

When creating SKUs for products, it is important to consider how the codes will be used. If a shop uses a POS system, the SKUs will need to be entered manually when adding products to the inventory. If the shop uses an ecommerce platform like Shopify, the SKUs can be automatically generated when the products are added to the site.

There are no hard and fast rules for creating SKUs, but it is important to make sure that the codes are unique and easy to remember or enter. A good system for creating SKUs will make it easy to keep track of inventory and make reordering simple.
