I will build vapi or retell ai receptionist for appointment booking and calendar sync


About this gig
Need an AI receptionist that answers every call and books appointments while you sleep? This Vapi AI or Retell AI voice agent picks up, talks like a real person, and puts bookings straight into your calendar.
Missed calls mean lost customers. Staff can't answer 24/7, voicemail gets ignored, and every unbooked caller goes to a competitor.
The result: a phone line that never misses a call, a fuller calendar, and less time on admin.
MY SERVICE FEATURES:
- Custom AI voice agent on Vapi AI or Retell AI
- Live calendar booking with real-time availability checks
- Google Calendar, Cal.com, Calendly or GHL calendar integration
- Rescheduling and cancellation handling by phone
- Human-sounding voice with ElevenLabs
- Twilio phone number purchase and setup
- Inbound call answering, 24/7
- Outbound AI calling agent for reminders and follow-ups
WHY THIS GIG:
- Real production experience: built a live multi-tenant AI receptionist for hotels, including dashboard and PMS integration
- Built on your accounts: you own everything, no lock-in
- Tested before delivery: booking, rescheduling and edge cases checked on real calls
- Clear communication: plain updates, no technical confusion
