EDI Solution

I am looking for an EDI product which can integrate with our solutions for a) Port Operations, b) Courier Trackming service, c) Cargo Tracking System for Middle East Carriers, Logisitcs.

The product should have scalability features which I couldeuse for additional solutions that we may provide.

The more vendor list I get, the better, and if anyone has a personal experience he/should share it with me
