What is public

The billing basis only: practices pay only when Zo successfully manages an appointment, with no time based charges, license fees, upfront fees, implementation costs or long term commitments. No rate is published, and a demo is the route in.

Variable cost rationale

Outcome based billing per managed appointment means cost scales with appointments Zo handles rather than call minutes; the rate is not published, so exposure cannot be sized.
