Hello Subbash, I personally worked with the folks from simploud.com, I can just say they know their business, no experience with QMSWrapper or greenlight guru
There are many options out there other than the 2 you mentioned, a couple of things to check:
- Flexibility, how complicated is it to implement, and more importantly, manage change to the system as you scale and/or regulatory requirements evolve.
- Cloud vs. on-premise.
- The system you see in the demo vs. real life.
- Cost, here you really want to check how much it really cost you, including the big unknown of consultancy.
- Training, do you need to train internal resources on the system's administration, how long does it take, what is your contingency plan to when they move on, this is especially important to smaller companies.
Hope it helped,
Jake
