With each system having its own list of inventory we need to make sure the SKU’s in the eCommerce site are the same as the SKU’s in Retail Express. The Supplier SKU is the most important one, but the Manufacturer SKU or "Grouping SKU" has a critical role too and is used alongside the Supplier SKU. 


This step is important not only in the setup but also to keep your products in sync with each system. The Supplier SKU is unique and is like the Barcode, the Manufacturer SKU is the grouping SKU.

It is certainly cleaner if there are no product in your eCommerce site while you setup REX.
