At least you got the interface to work. I paid $1000 to total MD and then $500 to AC and it has not worked. It has been 16 months and it doesn't work. It seems to us that the insurance and patient information has be double entered and so what good is the interface. I'm not throwing any more good money after bad. Serene...did you need to enter everything twice. That is what total MD told us. From their point of view there was and AC problem and from AC's point of view it was a total MD problem. I don't even have a contact person or means of communication from totalMD yet I get one way emails trying to sell something else quite frequently. It has been a major frustration. Not happy.
