Problem
Businesses lose potential clients because manual scheduling takes too long, requires staff availability, and leads to double bookings or missed calls.
Solution
VoiceBooker AI connects your voice assistant directly to Google Calendar. It listens to customers, checks your schedule, and books appointments automatically — all via natural conversation. No manual input, no back-and-forth messages.
Result
Scheduling time reduced by 90%, missed bookings nearly eliminated, and customer satisfaction increased due to instant voice confirmations.
Use Cases
VoiceBooker AI automates the entire process of booking appointments through voice interaction. When a customer speaks to your AI assistant (powered by Vapi), the agent checks your real-time Google Calendar availability, proposes suitable time slots, and books the meeting instantly. Ideal for service businesses like clinics, repair companies, and agencies — it replaces manual scheduling with seamless AI-powered automation. The workflow intelligently handles both availability queries and confirmed bookings while ensuring accurate time zone management and buffer times between meetings.
