This particular insurance company "just married" with a Clearinghouse that is trying to push their own billing system and making the life of the vendors very difficult (they want to take us out of the market we been for more than 20 years) so its not going to be easy but I need to do it for my clients.

Then it's probably best to build a small .NET app to interact with the web service and to access that from VFP as a COM object.
