What you’ll need:
Available on the Pro and Enterprise plans, and 14-day trial.
Admin access in Kommo.
Keep in mind:
Bookings are available only if at least one booking type and time slot are configured.
Available time slots depend on configured working hours and specialist availability.
The booking page becomes unavailable if no booking types are configured.
Disabled booking links can still be opened, but new bookings cannot be created.
Changes made to booking settings during the booking process may affect booking confirmation.
Clients do not receive automatic notifications after booking unless they are configured in the booking settings.
What are booking page errors?
If clients can’t create bookings or encounter errors during the booking process, the issue may be related to booking availability, scheduling settings, or changes made during the booking process.
Below are the most common booking page errors, what they mean, and how to fix them:
Booking page unavailable
If the booking page displays the following message: “Booking is unavailable. Please try again later”, it means that the booking page cannot be accessed.

This may happen if:
The booking link is invalid or no longer exists
The booking link is disabled
No booking types are configured
To fix this issue:
Go to Calendar → Booking links.
Make sure the Enable booking toggle is activated.
Verify that at least one booking type is configured.
No available time slots for the selected date
If clients can’t select a time slot, it means that no available booking slots exist for the selected date.
This may happen if:
Working hours are not configured
Booking settings restrict availability
All available slots are already booked
The selected specialist is unavailable
If no time slots are available for the selected date, the booking page displays a message indicating that there are no free time slots and suggests the next available date.

To fix this issue:
Check your booking availability settings.
Verify configured working hours.
Confirm that the selected specialist is available.
Review existing bookings and unavailable dates.
Selected time slot unavailable
If the booking page displays the following message: “This time slot is no longer available”, it means that the selected slot became unavailable before the booking was confirmed.
This may happen if:
Another booking was created for the same slot
Booking availability changed during the booking process
In this case, clients should click Select another time and choose a different available time slot to continue booking.

Selected specialist unavailable
If the booking page displays the following message: “This specialist is no longer available”, it means that the selected specialist became unavailable during the booking process.

To continue booking, clients should click Select another specialist and choose a different available specialist.
Selected service unavailable
If the booking page displays the following message: “This service is no longer available”, it means that the selected service became unavailable during the booking process.
To continue booking, clients should click Select another service. They’ll be redirected to the service list, where they can choose a different available service.
Booking confirmation failed
If the booking cannot be completed during confirmation, it means that booking availability changed while the client was completing the booking form.
This may happen if:
Booking settings were updated
The selected service or specialist became unavailable
The selected time slot was booked by another client
To fix this issue, clients should return to the booking page, choose another available service, specialist, or time slot, and complete the booking again.
Booking notifications not sent
By default, booking confirmations and reminders are not sent automatically after a booking is created.
To send notifications:
In the Calendar section, go to Booking settings → Notifications.
Configure a notification bot in the Bots section.
