Donna,
The reason AC may have actually decided AGAINST teaming up with a PM is because most of them suck so much. They are also expensive. It would be difficult to maintain such a relationshiop long term. Here is a list of possible problems:
1. Clients want to know why the EMR is only $2k per provider but the PM is around $5k.
2. Coordination between the PM tech-support and AC tech-support.
3. The "blame game." Something goes wrong and the PM tech-support guy blames AC, but the AC tech-support guy blames the PM. Do not write this one off. I have seen partnerships between companies in different industries, and this problem is VERY real.
4. People who buy the PM because AC recommends it only to not like it so they blame AC.
5. The PM vendor being upset sometimes because people buy AC but not the PM.
This list could easily go on. Food for thought.
