I don't think they are going to charge unless you do the integrated clearinghouse they provide - I am not sure if that means that they will actually fully integrate OA - I think full integration would mean that all the features he talked about including eligibility checking, electronic remittance, etc. I suspect that if OA is integrated it would only be that the program makes an output file compatible with OA. That being said I am just an observer and do not presume to speak for AC....
