SKUGen - SKU Generator for Shopify

SKU is short for Stock Keeping Unit, is made up of alphanumeric characters and is designed to be unique to a single product. It’s important to note that the SKU is not the same as a product’s UPC (barcode).

If you are selling products it is important to set up your inventory correctly and one of the most important parts of this process is setting up the product SKU.
