When setting up your Sellbrite account, the 2nd step in the setup process is to build products from your listings Sellbrite imported during step 1.
However, some channels are not able to build your inventory due to certain limitations.
Here is a list of all channels not available for building inventory:
Rakuten, Sears and NewEgg simply do not provide all of the relevant product information to build inventory, like product names and descriptions.
We recommend building your inventory from another sales channel if possible, or using the CSV upload option during this step.
