Sellbrite supports creating listings on Amazon for any ASIN. An ASIN is the official product identifier for items in the Amazon catalog.

If your products don't have ASINs, or are not in the Amazon catalog, you must first add your products to the catalog.
To do this, go to your Seller Central dashboard and either create your products one at a time, or use the appropriate catalog template file to create them in bulk.
Once the product page and listing have been created, you can simply import your newly created Amazon listing back into Sellbrite for inventory management.
