Solution
What Is Appointment Agent?
A voice AI agent that completes booking work over the phone—new appointments, confirmations, rescheduling, and cancellations—using your real availability and business rules.
What it handles
- Answer new booking calls and offer open slots that match the service the caller wants
- Write the appointment into the real calendar during the call, preventing double bookings and overlaps
- Confirm appointments and send reminders on the schedule you set
- Handle rescheduling and cancellations, returning the freed slot to availability
- Organize slots by staff member, branch, service duration, and buffer between appointments
- Transfer to a person for exceptions or whenever the caller asks to speak with someone
When it hands off
- Does not answer in-depth product, pricing, or policy questions from company documents
- Does not act as the organization-wide receptionist and call-routing layer
- Does not run high-volume outbound campaigns such as promotions or surveys
- Does not diagnose symptoms, give medical advice, or decide on a clinician’s behalf

No-Show Reduction
Reduce No-Shows from Booking to Appointment Day
A booking is not finished when the call ends. Confirmation, reminders, and effortless rescheduling protect calendar utilization.
Book
Complete the booking and confirm a real time slot.
Confirm
Send appointment details immediately.
Remind
Trigger reminders on your chosen schedule.
Reschedule
Let callers change appointments at any time.
Refill
Return cancelled slots to live availability.
Why effortless rescheduling matters
Many customers miss appointments because plans change, not because they forget. Always-available rescheduling returns capacity early while preserving the customer relationship.

FAQ
Frequently Asked Questions
How is the service priced?+−
Pricing is per AI concurrent line at THB 1,000 per line per month, including 400 conversation minutes per line per month. Additional usage is THB 3 per minute. The minimum is 2 lines (THB 2,000 per month with 800 minutes) on a 3-month minimum term.
Which calendar do we need if we still write bookings in a notebook?+−
The service works with Google Calendar or Microsoft 365, both of which you can start using at no extra cost from the provider side. Our team helps structure the calendar by staff member, room, or branch, and migrates your existing appointments during onboarding.
Can it really prevent double bookings and overlapping slots?+−
The agent reads live availability and writes the appointment into the real calendar during the call — not on paper for entry later — so it always sees the latest schedule, even a walk-in booked moments earlier. You can also set buffers between slots so services do not run into each other.
What if a caller wants to speak with a person?+−
Callers can ask at any point and the agent transfers immediately with a summary of the conversation so far. Your organization can also set automatic transfer rules — emergencies, damage claims, or VIP customers.
Where are appointment and patient data stored?+−
On AWS Bangkok (ap-southeast-7); data never leaves Thailand and the workflow aligns with PDPA. For clinics and healthcare providers, storage is limited to what an appointment requires, and your data is never used to train models or shared across customers.
How long until we can go live?+−
Typically about seven business days, covering calendar integration, queue and service-duration rules, phone-system connection, and live test calls with our team before the real number goes live.
How is this different from AI Receptionist?+−
AI Receptionist focuses on answering, welcoming, routing to the right department, and taking messages. Appointment Agent focuses on finishing the booking on the call — writing to the real calendar, confirming, reminding, and rescheduling. Many service businesses use both together.
How does it reduce no-shows?+−
The system sends a confirmation with the appointment details as soon as the booking is made, then reminds the customer again before the appointment on the schedule you set — three days and one day ahead, for example. Customers can call at any time to reschedule, and any slot that is moved or cancelled returns to availability for someone else to book right away.
