This may arise if The Software is set up as helpdesk software available to the customers as part of their service with The Licensees. This form of license ONLY applies if the users will be interacting with The Software directly (through email or through the web), not if the Active Users are using it for their own tracking only. Note that this license option may be in addition to an Internal Use license.

  Pricing for Pay for Service:

  100-500 external users: $750.00 / year
  500+ external users: Contact Author
