When I buy a Zendesk app that has a price per agent/month, how many agents will I be charged for?
Some apps sold in the Marketplace are priced as per agent/month. These apps charge only for the agents that are enabled to use them. On the My Apps page, in an app settings menu, you can configure Group restrictions in order to allow agents in a certain group to use the app:
In the example above, you are charged only for the number of agents in the Tier 1 group. When agents are added to or removed from the enabled groups, the billing amount is automatically prorated for the remaining billing period (month).
