Adding additional Amazon seller accounts is just as simple as when you added the first one.
From any screen click your account name and the dropdown menu below will be shown:
Simply click Add new account then follow the same 5 steps to connect your additional seller accounts as you did when connecting the first account.
The only difference comes in step 5 when you are connecting to Xero.
As this is an additional account you will have the choice to share the Xero connection or add a new one.
You would want to share the Xero connection if you are adding an additional Amazon seller account that uses the same Xero organisation as your existing account.
In this case simply select the organisation from the list shown in step 5.
If your new account uses a different Xero organisation you'll need to Add new Xero connection.
Simply click the Add new Xero connection button at the end of the dropdown list and log in to the right Xero account to connect it.
