I learned the hard way that the percentage charged is NOT the most important thing. The important thing is the bottom line, how much money comes in from your billing. I went with a LOUSY company that Amazing Charts worked with called SureData. I spent way too long with them and tolerated too much all just because of the nice export utility.

Now I work with a local billing company which handles about a dozen practices. I pay a whopping 8% but have a miniscule AR over 60 days. The end result is much better. In evaluating a company, ask to contact at least 8 clients and talk to the docs or the office manager.

Collecting a % on the copay seems reasonable, because they have to deal with that data. Never pay a % on cash paying patients, however.
