What counts as an agent license in Zendesk?

Question

How can I determine who takes up an agent seat in my account?

Answer

Anyone who is an agent in any capacity takes up an agent seat, including administrators and the account owner. Even suspended agents take up a seat. To free up that license, downgrade agents to end users before suspending their accounts.

This excludes light agents and contributors, who don't take a seat. However, contributors, who are also Chat agents, Guide agents, Explore Admins or Explore Editors, take up an agent seat. While light agents can be a Guide Viewer and not consume a seat, they will consume a seat if they are Chat agents, Guide agents, Explore Admins or Explore Editors. For example, an account on Zendesk Suite has five agent seats. If the account has one admin, three agents, and ten light agents, we would think that they have one available agent seat. However, one of the ten light agents is also a Chat agent, who takes up the final agent seat, so the account cannot add additional agents.

There are roles that require a Support seat depending on the product. For a complete list, see this article: Managing agent seats for Support.

Note: Sell account owners occupy a seat both in Sell and Suite plans.
