Create stores in application settings under the product sub-tab. Stores must have unique names containing alpha-numeric, underscore, or spaces only. Stores can be active or inactive, with inactive stores hidden in the user interface.
Most user interface elements within the application relating to stores do not appear unless there is at least one active store on the company account. Specifically, columns for importing store related information and fields on the product detail screen to edit per store configuration are hidden unless one active store exists.
