Dear Phil,
​
For getting started, the simple answer is that any CRM will do. A CRM system is like a young child. At first, the focus is just getting the child to talk and walk.  Long term, however, you want them to mature, learning and do more. As your client moves to do more, mature with their CRM system, that is where a basic tool and more advance tool quickly separate. 

Dear Bob,
 
We are an IT Services company. I have a client who uses Dynamics 365 CRM - but they're really frustrated with the tool. I would like to help them but the whole CRM business model is not a good fit for us. I also don’t want to lose my relationship with the client by just passing them off to anyone. However, I know that if I don’t take action soon the client will go out on their own looking for help, which might cut me out altogether.
 
What options do I have?
