What is a SKU?
SKU (stock keeping unit) is a unique sequence of alphanumeric characters that identifies and tracks inventory units (products). The use of SKUs is necessary for effective inventory management. SKUs are also an important part of the order fulfilment process as they simplify the flow of products and communication between the warehouse and the POS. Typically, SKUs are based on the product characteristics or category. For example, the following characteristics can be used for individual product identification: Type> Model> Color> Size> Location.
Here are some tips that can help you create SKUs:
- The code should not be long as it will be difficult to read.
- The first element of the SKU should be top-level information that will allow you to pre-define the product.
- Using a hyphen (-) as a separator improves the readability of SKU codes.
- Avoid using punctuation marks, special or ambiguous characters as some IT programs that will catalog the SKUs may have difficulty reading them.
How SKUs work in Voucherify?
In Voucherify, you can define many SKUs for each product. Each SKU can carry its own metadata and attributes. During the validation process, SKUs are treated as products. It means that SKU inherits the metadata assigned to the product and combines product and SKU attributes.
