Your Listings are the offers for your inventory on a sales channel. Listings are managed in the Listings tab.
Listings are not inventory
Unlike the products in your Sellbrite inventory, listings do not represent the items you sell. Listings are "offers" for the physical products you sell.
Thus, you can have many listings across all of your sales channels for one single product in your catalog.
