How to Fix Calendar Double Booking in GoHighLevel

If you use ClickUp to manage tasks and rely on GoHighLevel for appointment scheduling, double-booked calendar events can quickly create chaos. This step-by-step guide shows you how to troubleshoot and fix calendar double booking in GoHighLevel so appointments stay accurate and organized.

This article is based on the official documentation for calendar troubleshooting and focuses on diagnosing why double bookings happen and how to resolve each common cause.

Understand How GoHighLevel Calendar Booking Works

Before troubleshooting, it helps to understand how the booking logic in GoHighLevel works. When a contact books a time slot:

  • The system checks your calendar settings and availability windows.
  • It looks at your configured calendars and, if connected, your external calendars (such as Google).
  • It blocks out booked slots so new appointments should not overlap under normal conditions.

Double booking happens when one or more of these checks are misconfigured or bypassed. The following sections outline how to systematically locate and fix the root cause.

Step 1: Confirm Source and Recreate the Double Booking

Start by identifying exactly where the conflicting bookings came from in GoHighLevel.

  1. List the double-booked appointments.
    • Note the date, time, calendar name, and user assigned.
    • Check whether they were booked via a funnel, website, widget, link, or internal booking.
  2. Attempt to reproduce the conflict.
    • Use the same booking link or funnel step.
    • Use a different test contact email to avoid overwriting existing records.
  3. Record what you see.
    • Does the time slot appear as available even when it already has an appointment?
    • Do you see different behavior in different browsers or devices?

Reproducing the problem gives you reliable proof of the issue and makes further diagnosis in GoHighLevel much easier.

Step 2: Check GoHighLevel Calendar Configuration

Incorrect calendar settings are one of the most common reasons for double booking inside GoHighLevel.

Review Calendar Type and Team Setup in GoHighLevel

Each calendar type behaves differently, especially when teams or round-robin logic are involved.

  1. Open your calendar settings.
    • Navigate to the Calendars area inside your GoHighLevel account.
  2. Identify the calendar type.
    • Single user calendar
    • Round robin calendar
    • Collective or group calendar
  3. Verify user assignment.
    • Make sure that each user is correctly assigned and not unintentionally added to several overlapping calendars that use the same time slots.

In a round-robin or team setup, check that the same user is not being booked multiple times at the same date and time through different calendar configurations.

Validate Availability and Appointment Settings in GoHighLevel

Next, dig into the availability rules that the calendar uses to determine which time slots can be booked.

  1. Business and personal hours.
    • Confirm that working hours are set correctly for each day of the week.
    • Ensure you do not have overlapping availability windows that could allow multiple bookings.
  2. Appointment slot intervals and duration.
    • If your appointment length is 60 minutes, verify that your intervals and buffer times do not accidentally open the same time for multiple bookings.
  3. Buffer time and maximum bookings.
    • Configure buffer times before and after appointments if needed.
    • Check if there is a limit on the number of appointments per day or per time slot.

Any inconsistencies here can cause GoHighLevel to treat a conflicting slot as available when it should be blocked.

Step 3: Inspect Google or External Calendar Sync

Many double booking issues occur when external calendar sync is not configured as expected.

Check Calendar Sync Direction in GoHighLevel

GoHighLevel can both read from and write to external calendars such as Google Calendar. You must be sure this sync is correctly set.

  1. Open the user’s calendar integration settings.
    • Verify that the correct Google account is connected.
  2. Confirm sync direction.
    • Check whether the integration is set to two-way sync, or only push/pull.
    • If external events are not being pulled in, GoHighLevel may not see them as conflicts.
  3. Make sure the right calendars are selected.
    • If you use multiple Google Calendars, confirm that the calendar that actually contains the user’s busy events is included in the sync.

Verify Busy/Free Status in External Calendars

Even if sync is working, events might not be marked as busy.

  • Check that external events are set to “Busy” rather than “Free.”
  • Make sure all-day events that should block availability are configured to block time.
  • If external events are not busy, GoHighLevel may still allow bookings at that time.

If you need more detail on sync behavior, refer to the official help article at this GoHighLevel support resource.

Step 4: Review Funnel, Website, and Widget Settings

Calendars often appear inside funnels, websites, or widgets, and configuration in those locations can also contribute to double booking issues in GoHighLevel.

Confirm the Correct Calendar Is Embedded

  1. Edit the page or funnel step.
    • Open the funnel or website editor where the calendar is embedded.
  2. Check the calendar element.
    • Verify that the calendar selected in the element matches the calendar you are troubleshooting.
    • Make sure you do not have multiple calendar elements visible for the same user at the same time.
  3. Test the live page.
    • Use the live URL to confirm that only the expected calendar appears and that availability matches what you see in the calendar settings.

Inspect Booking Form and Custom Fields

Sometimes custom flows can inadvertently trigger more than one booking.

  • Review any automation or workflows triggered by form submission.
  • Confirm that a contact is not being added to multiple calendars at once.
  • Disable additional booking logic temporarily while testing.

This ensures the booking is created only once in GoHighLevel when a contact submits the form.

Step 5: Audit Workflows and Automation in GoHighLevel

Advanced automation is powerful but can cause duplicate or overlapping appointments if not correctly configured.

Look for Duplicate Triggers and Actions

  1. Open all workflows related to the calendar.
    • Search for workflows that fire on form submission, appointment status changes, or contact tags.
  2. Identify booking-related actions.
    • Look for actions that create or reschedule an appointment.
    • Make sure such actions are not duplicated by separate workflows running at the same time.
  3. Check conditions and filters.
    • Confirm that only the correct segment of contacts can trigger appointment-related actions.

If a workflow creates a new appointment when one already exists, you can end up with more than one booking at the same time slot.

Step 6: Test and Monitor After Adjustments

Once you have updated your configuration in GoHighLevel, it is essential to test and monitor for a period.

  1. Run structured test bookings.
    • Use several test contacts and booking links.
    • Test various time slots, including edge cases like the start and end of business hours.
  2. Check calendars after each test.
    • Confirm that each new appointment blocks the correct time.
    • Verify that external calendar sync reflects the new booking and does not allow overlapping slots.
  3. Monitor real bookings.
    • For the next several days, keep an eye on your appointment list.
    • Ask team members to report any strange overlaps immediately.

When to Contact GoHighLevel Support

If you have carefully followed all the steps above and can still reproduce double booking, you may be facing an edge case or a technical issue on the backend.

Before contacting support, gather:

  • Screenshot or video of the double booking behavior.
  • Calendar name and type, plus user details.
  • Exact steps you took to reproduce the issue.
  • Information on which browser and device you used for testing.

Providing this information allows the GoHighLevel support team to diagnose the problem more efficiently and confirm whether it is a configuration issue or something that requires engineering review.

Optimize Your Scheduling Workflow Beyond GoHighLevel

Once your double booking issues are resolved, consider optimizing your full workflow so appointment data, tasks, and follow-ups stay in sync across tools.

  • Standardize which calendars each team member uses for external events.
  • Document how funnels and websites should embed calendars.
  • Align automations so that no more than one workflow can create or modify an appointment at the same time.
  • Periodically review your settings, especially when you add new team members or calendars.
