Book against live availability without double-booking
As an AI receptionist Google Calendar integration, Heyfon reads your real availability during the call, offers slots that actually exist and writes the appointment straight in. No booking requests to action later.
How it works
Connect Google Calendar
Authorise the calendars Heyfon should read and write, per team member if needed.
Set your rules
Opening hours, appointment durations, notice periods and buffers between bookings.
Heyfon offers real slots
It reads live availability during the call rather than working from a fixed list.
Appointment written and confirmed
The event lands in the calendar and the caller gets a written confirmation.
The difference between booking and requesting
Most call handling produces a booking request that somebody has to action, by which point the slot may be gone and the customer may have booked elsewhere. AI appointment booking against Google Calendar means the transaction completes inside the conversation: real availability read, rules applied, event created, confirmation sent, all before the caller puts the phone down.
- Reads live availability rather than a static list of slots
- Books the correct duration for the service requested
- Respects opening hours, notice periods and buffers
- Prevents double-booking across people or resources
- Writes the event with the caller’s details attached
Rescheduling and cancellation, not just creation
Most systems handle the first appointment well and everything after it badly. A customer who needs to move Thursday can do it in conversation: Heyfon finds the next suitable slot, updates the calendar and releases the original slot so the next caller can have it. Nobody at your business touches the phone.
Multiple calendars and team members
Where your business books against individual people, Heyfon can read each of their calendars and book with the person the caller asks for. A salon client can request their usual stylist, a clinic can route to a specific practitioner, and the slot offered is one that person can actually work.
- Per-person calendars for teams
- Callers can request a specific team member
- Capacity rules for rooms, ramps or chairs
