Schedly + Google Calendar

Calendar synchronization sounds like a solved problem -- of course scheduling software should sync with your calendar. The critical distinction is between polling-based sync (which checks for updates every 15-30 minutes and creates a window of potential double-booking) and real-time sync (which reads your calendar in the moment a client is trying to book). Schedly's Google Calendar integration provides real-time bidirectional sync, meaning that a calendar event added to Google Calendar at 9:00am makes your 9:00am slot unavailable on Schedly at 9:00am -- not at 9:15 or 9:30 after the next polling cycle.

Multi-Calendar Conflict Checking

Real professionals maintain multiple calendars simultaneously -- a work Google Calendar, a personal Google Calendar, and sometimes a shared family or team calendar. Single-calendar sync misses conflicts from the other calendars entirely. Schedly connects to multiple Google Calendars simultaneously and checks all of them for conflicts when evaluating your availability. A dentist appointment on your personal calendar prevents a client booking in that slot, just as a work meeting would. This comprehensive conflict checking eliminates the double-booking scenarios that single-calendar tools inevitably create.

The Confirmation Email as a Calendar Invite

Every Schedly booking confirmation automatically adds the appointment to the client's calendar via a .ics calendar invite attached to the confirmation email. When the client accepts the calendar invite, the appointment appears in their Google Calendar with all booking details -- service description, meeting link if virtual, location if in-person, and host contact information. This creates a shared calendar entry that serves as the authoritative record of the appointment for both parties, reducing missed-appointment cancellations dramatically.
