PF is free and also very good. Most people who use it like it, better than some paid EMR.
They have competition, office ally charges a very small fee for EMR, and free PM.
I see no reason why anyone should pay for EMR.
I don't think PF will be charging anyone. The major competition is from Kareo, Nuesoft, AdvancedMD, Carecloud, ECW and dozens of others who give out free EMR and PM for doing billing at 4% or less. Of course they send all the work offshore.
Try getting a new client these days, see who you are competing with.
