We have been working with our trusted partner Service Stack for a number of years and they have proved time and again that they are very capable of helping us develop and expand the use of our ServiceNow practice. Service Stack Technologies is handling our enhancements, projects (which includes Service Portal, Finance, Facility and Legal modules and a number of custom solutions) and recently did a Zero Defect version upgrade. On more than one occasion they have done more than expected.
