Spirit Cultural Exchange has been working with Engineered IT for over 10 years and has relied on them for all of our operational systems development including CRM, finance and systems integration with suppliers and governmental entities. EIT has worked seamlessly with our internal staff to develop requirements and implement every type of system improvement including minor fixes, major functional enhancements, and even a complete system migration to a web based cloud platform. EIT is particularly good at taking rough functional specifications and working with our users to design a system flow and user interface that best meets their needs. Their deliverables are accurate the first time and never need major testing or design rework. EIT is a true business partner.
