Jay,
I see you are from my old stomping grounds downstate. Where are you exactly. My wife and I grew up in the northwest Bronx, and we both spent our summers in Putnam and I fished the Res's up there with my dad a whole heck of a lot too. West Branch, Croton, the Muscoot.
Anyway, OfficeAlly seems to be more of a west coast thing than an east coast thing so check carefully if they have agreements with your carriers down there. For example our largest and most painful carrier, our local BC/BS Excellus (really a pawn for Wellpoint) was not with them and so over 50% of our claims would have had to drop to paper if we went with them. Look before you leap. Anyway, I keep thinking about dropping our present billing company and trying Altapoint at some point. They changed their website for the worse so there is a whole lot less info there then there used to be. Good luck.
Paul
