Zynbot
After being through many helpdesk systems, from Zendesk to manage attendant, this was the one that stood out from the crowd and not for just one reason. We wanted something with felxability and customizable features. Not only does this have all the features that other helpdesk systems shine on, but after working with the support team here, they were extremely helpdesk on creating new features that would help my company work more efficiently on this system.
