Most sellers use the name of their Amazon account, however, it does not have to be a registered business name. It will only be displayed on the FBA Shipping Label so it can be changed later if you wish to change it.
To change your business name in Stratify for the shipping label, click on your name in the upper right and corner of InventoryLab and select Settings from the dropdown menu, then List.
To expand or collapse the Ship From Address section, click the blue arrow in front of Ship From Address
Click the Pencil icon next to the address you need to update
Then, type in a new business name and click Save Address
