# AI Appointment Booking on Phone Calls > How AI appointment booking works on a phone call: services with time and charge, seats, hours, only free slots offered, and WhatsApp confirmations. Source: https://business.mysmartassistant.ai/blog/ai-appointment-booking · Published 2026-10-23 · Language: English · Publisher: MySA Business (https://business.mysmartassistant.ai) AI appointment booking means a customer rings your business number, an AI voice assistant answers, checks which times are actually free, and books the slot before the call ends. The customer then gets a WhatsApp confirmation with the service, date, time and your address. In MySA Business this runs on **Appointments**, a calendar built for businesses that sell time on a seat: a salon chair, a clinic room, a service bay. ## What the calendar needs to know first The AI can only offer a time it knows is real, so the work starts with a short six-step setup: - **Services.** Pick your kind of business (salon, clinic, dental, spa, gym, car wash and more, or *Something else*) for a starter list. Each service gets a length, from 5 minutes to 4 hours, and your charge in rupees. - **Seats.** One seat is one customer at a time: a chair, a bed, a bay or a doctor, optionally named after the person who works it. Each seat is a column on the Day view. - **Days, hours and lunch break.** Nothing is ever offered during the break, on screen or by the AI. - **Booking rules.** The largest group one booking can take, the minimum notice, how many days ahead customers can book, and whether **AI books on calls**. - **Reminder rules.** How a confirmed booking is reminded. Start times are offered every *shortest service's* length: with a 15-minute service, customers can start at 10:00, 10:15, 10:30, and a 45-minute service takes three of those steps. ## How the AI books during the call With **AI books on calls** ticked, the assistant on your calls can do four things: | The customer says | What the AI does | |---|---| | "Kal shaam ko haircut ka time hai?" | Checks free times for that service, day and group size, and offers the nearest free times if the asked-for one is taken | | "Theek hai, 5:30 rakh do, naam Priya" | Books the slot. The phone number comes from the call, so it never asks for it | | "Mera Thursday wala appointment Saturday kar do" | Moves the caller's own upcoming booking, as the same booking rather than a cancel and rebook | | "Mujhe cancel karna hai" | Cancels the caller's own upcoming booking | Before moving or cancelling, the AI asks one short question about why, and saves the answer in the booking's notes. It only ever touches bookings made for the number the customer is calling from, follows your minimum notice, booking window and lunch break, and makes at most one booking per call. > **Example** > > **Caller:** Hello, Sunday ko facial ke liye slot milega? > > **AI:** Sunday ko 11 baje aur 2:30 baje slot khali hai. Aapke liye kaunsa theek rahega? > > **Caller:** 2:30. Naam Neha likh dijiye. > > **AI:** Ho gaya Neha ji, Sunday 2:30 baje facial book hai. Confirmation WhatsApp par aa jayega. The booking appears on the calendar straight away with a small robot icon. If a customer agreed a time on a call but it was not booked, it shows as **Not confirmed yet** with a note, so your team can confirm it. For the AI to book, you need your **Live** workspace (Test and Live have separate calendars), Appointments switched on for your business, at least one seat and one service, **AI books on calls** ticked under Settings → Hours & rules, and [inbound calls](/features/inbound-calls) switched on for the number customers ring. ## WhatsApp confirmation, change, reminder and cancellation For Live bookings, the customer gets a WhatsApp from MySA's WhatsApp number, to the mobile on the booking: - **Confirmed:** service, date, time, your address, your Google Maps location and your number. - **Time changed:** the new date and time, and your number. - **Reminder:** service, date and time, sent between 30 minutes and 1 day before, 3 hours by default. - **Cancelled:** which booking, and your number to book again. A booking marked *Not confirmed yet* gets nothing until you confirm it, a walk-in gets no messages, and a booking made inside the reminder window gets the confirmation only. Test bookings never send a WhatsApp. An optional **reminder call**, off by default, has the AI ring before the booking and ask whether the customer is coming; the answer is saved as a flag and never cancels anything by itself. The full comparison of WhatsApp reminders and reminder calls is in our guide to [automated appointment reminder calls](/blog/automated-appointment-reminder-calls). ## A copy of every booking in Google Sheets Click **Connect Google Sheet**, share your sheet as Editor with the address shown, and paste its link. A **Bookings** tab then holds every booking from the last 365 days plus everything coming up, with customer, phone, service, price, status and notes. It is rebuilt within a minute of any change, so keep your own notes in a separate tab. ## Which businesses it suits These are scenarios, not customer stories: - **Clinics and dental practices.** A seat per doctor, each service with its own length. See the [clinic AI receptionist](/industries/clinic-ai-receptionist) and [doctor appointment booking with AI](/blog/doctor-appointment-booking-ai). - **Salons and spas.** A seat per chair or bed, with group bookings up to your largest-group rule. See [salon appointment booking](/industries/salon-appointment-booking). - **Coaching demo classes.** Choose *Something else*, make "Demo class" a service and each counsellor a seat. - **Service bays and car washes.** A seat per bay, plus the reminder call for fewer no-shows. ## Getting started Sign up, verify your mobile number for ₹100 of Test credit, and build your calendar in the Test workspace to check services, hours and rules. When it looks right, set it up in Live and switch on inbound for your number. The step-by-step is in the [Appointments documentation](/docs/appointments), and the feature overview is on the [AI appointment booking page](/features/appointments). ## Frequently asked questions ### Can the AI book an appointment during a phone call? Yes. With AI books on calls switched on in your Live workspace, it checks free times for the service, day and group size, books once the customer picks a time and gives a name, and the customer gets a WhatsApp confirmation. ### Will the AI offer a time when we are closed or at lunch? No. It offers only times inside your open days and hours that a free seat can fit, never during the lunch break, and it follows your minimum notice and how-far-ahead rules. ### Does the AI ask the customer for their phone number? No. The number is taken from the call itself. The AI asks for a name, and it only moves or cancels bookings made for the number the customer is calling from. ### What WhatsApp messages does the customer receive? A confirmation, a message if the time changes, a reminder before the booking (3 hours by default), and a message if it is cancelled. They go only for Live bookings, and not for walk-ins or bookings not yet confirmed. ### Can my staff still book appointments by hand? Yes. Staff can click New booking or any free slot on the calendar. Two bookings can never hold the same seat at the same time, whether the staff or the AI made them. ### Can I see all bookings in a Google Sheet? Yes. Connect a Google Sheet you own and a Bookings tab is kept in step with the calendar, rebuilt within a minute of any change.
