Lumina has been using Agiloft (and its predecessor SupportWizard) for 7 years, for issue tracking, and customer support. We have found it outstanding in its flexibility, ease of use, and reliability.
Agiloft has always been quick to solve the few (if any) problems that have occurred, and they are happy to help customize the product to better align with my organization's needs.
The customer support team is very reliable and clearly interested in building long-term customer relationships.
Some of it can be very confusing to someone who doesn't understand business flow.
Some errors may occur when merging several operations together.
It is a little bulky and for old school sales, it tends to be a little difficult to maneuver from section to section.
