With our Mantis support portal you can create, monitor and check upon service tickets regarding software problems. Link to the support portal.
 

Every service ticket is integrated in a work flow status (e.g. new, assigned, fixed, closed). Special access authorization is required to change the service ticket status. Remarks and commentary can be entered by any project team member throughout the service ticket life cycle. An option to leave a comment in between a status change is offered, to be able to fully understand all of the changes and adjustments.
