Resolve time slot availability issues
1. Purpose of this guide
This guide explains why certain expected time slots might be missing from your booking page and how to identify and resolve such issues. This can happen due to several configurations at the business, user, or event type level.
2. Possible causes and solutions
2.1 Block time (Unavailability)
Any unavailability configured for the business, user, or event type working hours makes the corresponding time slots unavailable.
To resolve this:
- Business Hours: Admin Center
> Business Hours > Unavailability
- Users: Users > Select a user > Availability > unavailability
- Event Type: Event types > Select Event Type > Availability > Unavailability
Solution:
Review and update any unavailability settings to restore hidden time slots. For example, if unavailability is set from Jan 1 to Jan 5, no time slots will appear during that period. Removing or adjusting these settings will make the slots visible again.
2.2 Scheduling window configuration
The scheduling interval controls when appointments can begin. Slots are only shown at those specific intervals.
To resolve this:
Event Type > Scheduling Rules > Scheduling Interval
Solution:
Modify the interval if you want to offer more frequent appointment options. For example, if a 30-minute fixed interval is set, slots will only appear at 9:00 AM, 9:30 AM, 10:00 AM, etc. Intermediate times like 10:15 AM or 11:15 AM won't be available. Reducing the interval to 15 minutes will allow additional options such as 9:15 AM, 9:45 AM, and so on.
2.3 Buffer time
Pre-buffer and post-buffer settings reduce the total available time slots within the working hours.
To resolve this:
Event Type > Scheduling Rules > Buffer Time
Solution:
Adjust the buffer times to maximize slot availability within your working hours. For example, if your working hours are from 9:00 AM to 6:00 PM and you’ve set a 1-hour pre-buffer and post-buffer, appointments can only be booked between 10:00 AM and 5:00 PM. Reducing the buffer time will open more slots within the available hours.
2.4 External calendar sync
Events from synced external calendars (like Google Calendar) block those time slots in Zoho Bookings.
To resolve this:
Click the calendar icon 
at the top-right corner > Choose the user > View the events of the day.
Solution:
Remove or reschedule the conflicting event in the external calendar to free up the time slot in Bookings. For example, if a synced Google Calendar event is scheduled at 4:00 PM and your business hours are from 9:00 AM to 5:00 PM, the 4:00 PM slot will be blocked in Bookings.

2.5 Event type availability
Time slots outside of the defined working hours for the event type won’t be shown on the booking page.
To resolve this:
Event Type > Availability > Working Hours
Solution:
Update the working hours or days to ensure slots appear as expected. For example, if the available dates are set from Jan 1 to Jan 15 and working hours are 5:00 PM to 9:00 PM on Mondays and Wednesdays, slots will only be shown during that specific window.
