Prevent Overbooking with Real-Time Team Availability: Calendly + HeavySet Tech

By integrating Calendly with HeavySet Tech, your form can display real-time availability, allowing website visitors to quickly select and book open slots. This integration prevents overbooking, ensures appointments don’t exceed your team’s capacity, and simplifies the entire scheduling process for both you and your clients.

By using Calendly with HeavySet Tech, you can connect multiple calendars — such as Outlook or Microsoft 365 — to manage your availability all in one place. This integration automatically checks blocked time slots across all connected calendars to keep your schedule accurate. You can set up a single calendar per schedule or multiple calendars for the same schedule, providing the flexibility you need for your unique workflow.

Why Connect Calendars?

Every time a user interacts with your HeavySet Tech form, our platform checks your connected calendars for availability and displays open slots based on the defined recurring schedule. You can:

  • Block days on a specific schedule when needed.
  • Choose to automatically block major holidays.
  • Handle multiple availability blocks across different calendars.
  • Have appointments automatically added to your calendar once booked.

When an appointment is created through HeavySet Tech, an invite is sent to the calendar’s associated email. Most email clients let you whitelist our sending address ([email protected] ) so that appointments are automatically added to your calendar.

If you select the appointment and click No to decline, our platform is immediately notified and makes that slot available for another appointment. If you do not respond, our platform will hold your slot until 5:00 PM on Monday if the request is made on a Friday, Saturday, or Sunday. Otherwise, the slot will be released after 24 hours.

Final Tips

  • Whitelist [email protected]  in your email client to ensure invites are automatically added to your calendar.
  • Declining an invite in your email/calendar will free up that slot immediately for another appointment.
  • If you ignore an invite, our system will automatically release the slot at 5:00 PM on Monday if the request is made on a Friday, Saturday, or Sunday. Otherwise, the slot will be released after 24 hours.

By connecting Calendly with HeavySet Tech, you can display real-time availability directly in your HeavySet Tech form, allowing website visitors to select and book open slots without exceeding your team’s capacity. This integration automatically updates schedules across all connected calendars, preventing double bookings or overscheduling and making the appointment process easier for both you and your clients.
