I don't want my Support seat/license taken up by a Sell user. How do I create a Sell-only agent when I have a Zendesk Support subscription as well?
Create your Sell-only users from your Zendesk Sell Settings > Users instead of creating the profile in Zendesk Support. For more information on how to create a user for Sell, see the article: Adding a user in Sell.
Sell users will then be added to your Support account as contributors that don't take a Support license. For more information about the contributor role for Zendesk Support, see the article: Creating custom roles and assigning agents (Enterprise).
