John,
First, welcome to the board.
Folks using AC tend to fall into 4 groups when it comes to PM, and much of that depends on how you are currently/plan-to handle billing.
In-house biller - they use an in-house system, which may or may not have an interface with AC. Lots of choices here, and I'm sure happy/unhappy users will chime in.
Out-house biller - they take paper superbills and do billing on their system. In my experience this may show as the numerically smallest cost, but also generates the most headaches, frustration, no usable PM, and IMHO the lowest gross billing amount of the choices.
Out-sourced billing - the good ones have some level of integration with AC, and provide the practice with 24 hr access to claims scrubbing, electronic submission, reports, billing information, re-submission, and business data visibility.
The fourth group you ask? They have a biller/PM they aren't happy with and are looking for a new one.
