That's a risk I'm willing to take. There is no non-compete clause in our agreement, and I am very open in my conversations with my billers about "going independent". In ten years of working with sub-contractors, I've never had anyone take me up on the offer of becoming their own billing service (they don't want to deal with the problems, they don't want the responsibility, etc., etc). There are plenty of providers to go around, so I concentrate on doing good work and taking very good care of my people.
