===== HD Contracts =====

[[Contract]]s represent the actual support contracts binding [[CUSTOMER]]s and the helpdesk-providing entity, supposedly the site owner.

Contracts can be
  * limited by time spent 
  * limited by duration (yearly, for instance)
  * limited by number of tickets

[[TECH]]s can define whethere contracts can be suspended/reactivated by their owning [[CUSTOMER]].

All [[TICKET]]s and [[FOLLOWUP]]s can be charged to only one contract each. However, they can also not be charged, in which case they are subject to an [[ATTENDANT]] binding them to a contract prior to being considered active.
