Can the agent offer times that are already taken?

No. It checks availability at that moment, cross-checking your configured hours, already booked appointments and the connected Google Calendar. If a slot is taken, it doesn't offer it.

Where do I set my business hours?

In your business and staff hours (Business / Team, the Hours and Scheduling tabs). If you put them in the prompt they go stale and the agent offers fake times.

Does it connect to Google Calendar?

Yes, from Integrations. When it's connected, the agent respects whatever is already busy on the calendar and doesn't offer it.

How AI appointment scheduling works on WhatsApp

TBit's agent schedules, reschedules and cancels appointments on WhatsApp with real availability, cross-checking hours, appointments and Google Calendar. Where to set it all up.

What it does

The agent schedules, reschedules and cancels appointments by chatting on WhatsApp. It only offers times that are truly available and records the appointment in your business calendar.

How it works

Availability comes from three sources: your configured business and staff hours, already booked appointments, and the connected Google Calendar (if a slot is busy on the calendar, the agent doesn't offer it). The agent checks that availability at that moment, suggests options and confirms the appointment with the customer's details.

Where to set it up

Bookable services and their duration: the Scheduling menu.
Business and staff hours: Business / Team, the Hours and Scheduling tabs.
Google Calendar connection: Integrations.
The calendar with booked appointments is in the Scheduling menu.

What NOT to put in the prompt

Business hours ("we're open 9 to 6"): set them in your business hours. If they go in the prompt, they go stale and the agent offers fake times.
Lists of services with duration and price: they go in your bookable services.
Availability rules ("don't schedule on Sundays"): your configured hours rule.

The prompt can define the tone when scheduling and your own policies, for example asking for a deposit or confirming in advance.
