# Easier Bookings and Cancellations with Calendar Sync ## Easier Bookings and Cancellations with Calendar Sync > We love the fact that once the integration was completed it will now be a simple process for our users to connect their accounts to Cronofy. Since we get users with varying IT skills it was important for us to keep the process quick and easy. Mission accomplished! — Tapan Karambelkar, Product Manager, ResBook ## Save time, book online Online booking can save both you and your client time, but connecting to the APIs of multiple calendar softwares is time-consuming and requires ongoing maintenance. Our [Availability API](https://www.cronofy.com/availability-api/) connects to all calendar services, allowing for a client’s availability to be synced to your booking system in real-time. As soon as a slot is taken up, it’s removed from the booking system’s calendar. ## Send booking details to a customer's calendar It can be easy for a customer to forget to add their booking to their calendar. Even more so if they have to juggle between personal and professional calendars. This can lead to double-bookings or missed appointments for them, and lost revenue for the business. With [Cronofy’s Calendar API](https://www.cronofy.com/features/), details of the booking can be sent straight to the customer’s calendar and synced to their other calendars. Should anyone need to make any changes, they can be done from the booking system or the calendars. The event will then be updated in real-time. ## Avoid missed appointments When a customer can no longer make an appointment, it can get expensive, especially if they don’t cancel and free up the slot for someone else. With Cronofy, customers can make changes straight from their chosen calendar service. Notification about the changes can be sent to other attendees and to the booking system, and, if necessary, automated messages can be created to get in touch with the customer for confirmation. ## Don't compromise on privacy While businesses need to know details of their customer’s bookings, they don’t need to access other personal details held into calendars. Our Calendar API ensures customer’s privacy throughout. You can choose to only see relevant calendar events details such as free/busy information. Customers, meanwhile, don’t need to share sensitive information about medical appointments or nights out which makes it a lot easier for them to agree to share their calendars with booking systems. ### How Wise cut interview scheduling from 6 days to 90 minutes Learn how Wise, a global technology company with a mission to move the world’s money, accelerated their time-to-schedule with Cronofy’s scheduling automation and transformed their candidate experience.
