Rainy,
What PM are you using for billing now? I'm not "feeling the love" for the new, upcoming, soon, (maybe) Office Ally Practice Mate. Do you really want all your office financials on a web server somewhere? What if they go broke, get sabotaged, suffer an EMP burst, whatever. Of all the things I want physical control of, the financials may be of more importance to me personally than the patient notes. Anyhow, AC needs to get it together on the PM side, or risk becoming obsolete.
