We are a billing service and have providers using AC now where we enter their charges. We also offer an option to host AC and link with Medisoft so the provider can enter charges in AC, have them then appear in Medisoft and then send out (direct to some payers, to a clearinghouse for most)...And you can buy the cheapest version of Medisoft ($299.95) if use choose our Basic or BasicPlus Service. You then have full use of Medisoft, including all financials.
