What Slotbook does

Public booking page
A link for your customers to pick a service, date and free slot and book in under a minute, with a reference number.
No double bookings
Slots are worked out from your hours, service durations, closed days and existing appointments, so a taken time is never offered.
Day timeline
See each day laid out by the hour with a marker for the current time, and a week strip showing how full each day is.
Walk-ins and phone bookings
Add appointments yourself, reschedule them, and keep notes for each customer visit.
Status tracking
Mark appointments booked, confirmed, completed, cancelled or no-show and filter your list by any of them.
AI message drafts
Get a confirmation, reminder, reschedule or thank-you message drafted from the appointment details, then copy it or open it in a chat app.
Booking reports
Bookings per day, busiest weekdays and hours, top services, no-show rate and earnings from completed visits.
AI booking summary
AI reads your booking numbers for the chosen period and writes plain observations and suggestions.
Closed days and hours
Set working days, opening hours, slot length, booking notice and holidays your customers cannot book on.
CSV export
Download all appointments and services as CSV files whenever you need them.

How it helps

Slotbook is an appointment book for businesses that run on time slots: clinics, salons, tutors, consultants and repair desks. You list your services with their duration and price, set your working days and hours, and Slotbook works out which slots are free.

Every business gets its own booking page link. Share it on your profile, in messages or on a printed card. Customers choose a service, a date and an open slot, leave their name and phone number, and get a booking reference. Slots that are already taken, past, or on days you have marked closed are never offered, so the same time cannot be booked twice.

You work from a day view that shows the day as a timeline, with a week strip to jump between days. Add walk-ins and phone bookings yourself, move appointments, and mark each one confirmed, completed, cancelled or no-show. A reports screen shows bookings over time, busy weekdays, top services, no-show and cancellation rates, and earnings from completed visits.

AI helps with the writing: it drafts confirmation, reminder, reschedule and follow-up messages for a customer from the appointment details, ready to copy or open in a chat app. It also reads your booking numbers and writes a short summary of patterns with practical suggestions. Everything works without AI too, and you can export your appointments and services as CSV at any time.

Questions about Slotbook

How much does Slotbook cost?

There is a free plan. Starter is ₹299 a month and Pro is ₹799 a month. Paid plans raise the limits on services, bookings per month and AI requests.

What do I get on the free plan?

Up to 3 services, 40 bookings a month (from your booking page and ones you add yourself), the public booking page, reports, CSV export and 10 AI requests a month.

Can two customers book the same time?

No. Slotbook keeps one calendar per business and only offers slots that are free for the full length of the service. It suits businesses that serve one customer at a time per calendar.

Does Slotbook send messages to customers automatically?

No. AI drafts the message for you and you send it yourself by copying it or opening it in a chat app on your phone, so nothing goes out without you seeing it.

Can I export my data?

Yes. Appointments and services can be downloaded as CSV files from the settings screen on every plan.

Does it work on a phone?

Yes. Both your appointment book and the customer booking page work in a phone browser, so you can check the day and add walk-ins from the counter.

What happens when I reach my monthly booking limit?

New bookings are paused until the next month or until you upgrade. Your booking page tells customers to contact you directly, and your existing appointments stay as they are.
