I too have been trying to interface Medisoft/AC. I bought the $500 interface from AC, but have discovered (finally after much emailing and phone calling) that the interface won't work without additional expense. As Paul at AC tech support (the interface expert) wrote me: "The bottom line is you need either X-link [$2000], Communications Manager [$1395] from Medisoft, or some other product to make Medisoft and Amazing Charts communicate to each other. X-link will do it all after purchasing their product. Medisoft?s communications manager is probably the same price and I don?t know anyone who has been able to get an answer from them on how to make that work."
I have given up on the interface idea and hope AC's PM software comes out soon and works well.
