Add a Secondary User
How to give other people access to your Amazon Seller Central account. This is in two parts - 1) inviting the user and 2) adding required permissions once they've accepted the invitation
Under Settings, click User Permissions.
Once they have accepted, you will need to add access permissions. Go back to the User Permissions page.
Click Manage Permissions next to the new account.
Click the checkbox under “View and Edit” to assign permissions. See below for usual access required.
Always Required: Manage Inventory/Add A Product, Manage Your Cases (under settings), Business Reports, Sales Summary (in the Reports section)
Inventory and FBA - Everything in the “Inventory” section
PPC campaigns - Everything in the “Advertising” section
Reporting & Audit - Everything in the “Reports” section
Amazon Stores - Everything in the “Store Design” section
You will need to do this separately for EU and USA Amazon accounts if access is required to both.
