2. On the left side, under Seller Account Information, go to the Your Services section and click Manage.
3. In the Sell on Amazon row, under the You are signed up for section, click Upgrade.
4. Review the terms on the next page, and then click Proceed to Upgrade. You will be returned to Your Services. A message will appear indicating that the upgrade process has started.
