Business agent license is a specialized pricing license available as an add-on in Freshservice that can be leveraged by business teams. A business agent belongs to business teams like HR, Finance, Facilities, Legal, Admin, Sales, Marketing, etc., and is available for purchase on Pro and Enterprise plans.
You can purchase this add-on from Admin > Plans and Billing.
Note: Once you add business agent licenses to your account, you can use them in business workspaces (any workspace created for a business team). Pro/Enterprise agents converted to business agents will lead to Incidents/Service Requests assigned to them getting unassigned as business agents can only be assigned tickets in business workspaces.
