Calendar Sync for Bookings keeps your booking calendar in step with the calendars you and your staff already use. When someone is busy in Google Calendar, Outlook, Microsoft 365 or iCloud, that time is blocked for online bookings, so clients cannot book a slot that is already taken.
Link each staff member's calendars with their private iCal address (a two-minute step, explained in the app). You can link several calendars per person, such as work, personal and family. Busy events become blocks named "Busy (Calendar Sync)". Event titles stay private and never appear on your site.
All-day events such as holidays and days off can block the whole day, even when the calendar marks them as free. On the paid plan you can add buffer time before and after events and ignore events by keyword. "Why is this time blocked?" shows which event caused a block.
Each staff member also gets a private booking feed: subscribe to it in Google, Apple or Outlook to see the bookings in a personal calendar.
Free plan: one staff member with one calendar, checked every hour, 30 days ahead. Pro: up to 10 staff members with 5 calendars each, checked every 10 minutes, 180 days ahead. 14-day free trial.
