A product refers to the broadest classification of the goods that make up your inventory.
Example
If you sell clothing your products would consist of shirts, dresses, shorts, etc.
Products can then be further broken down into variants and in some cases bundles.
You can upload products both individually or in bulk via CSV.
After you import your products onto QuickBooks Commerce, you will be able to view and manage your products via the Inventory section.
