Easy Appointment Booking directly integrates with Google Calendar. Once you connect your Google account with Easy Appointment Booking, all Shopify bookings that are created will automatically be synced to your calendar. Cancellations and reschedules will automatically sync as well.
Easy Appointment Booking will also look at your Google Calendar to see when you are unavailable. Any time blocked off on your Google Calendar will automatically be removed from your availability to make sure you aren't double booked. You can learn more about our Google Calendar integration
