One thing about Medware/Sage/Vitera is there webmaster worked for the CIA/FBI/Homeland Security. To try to find the Medware site, takes a good deal of time and patience. I finally dialed the number above and after a good deal of waiting got a woman on the phone who actually asked me to spell Medware. This is akin to a Microsoft sales person asking me to spell Outlook.
But, once you do purchase, it is inexpensive and support is very good if you hit the right button.
