RingOperator is a 24/7 AI voice agent for small businesses that book appointments over the phone - salons, clinics, auto shops, home services and solo law or accounting practices. It answers calls, syncs bookings to Google Calendar and handles routine questions, with no POS or order-taking features to pay for. The Starter plan is $25 a month, aimed squarely at solo operators who have never been able to afford a receptionist service.
