I am part of University of Chicago Medical Center, and we have worked with EC Sourcing Group for about three years.
I run a team of folks that does all of the sourcing for clinical equipment, supplies, etc. Their software really met our needs and lets us run our own events effectively.
EC Sourcing Group has a competitive price point, are very flexible to work with, and provide regular updates and improvements. Their tools hit all the marks.
It is pretty easy to train new employees on the software. We also have a number of licenses with them to get training from them directly. Their lead trainer is extremely helpful. I would recommend their services.
