If you list your property on more than one site, you’ll quickly run into the question of how to keep calendars updated. Here’s a clear breakdown of the two main options.
iCal — The Elegant Free Solution
iCal is a sleek, universal calendar link (.ics) that most major platforms (Airbnb, VRBO, Booking.com, and others) offer at no cost.
- Simply copy a link from one platform and drop it into another.
- It intelligently syncs your availability, automatically blocking dates across sites the moment a booking comes in.
- Updates flow smoothly in the background, keeping your calendars aligned with minimal effort.
- It’s lightweight, widely compatible, and requires no monthly fees or complicated software.
- While it focuses mainly on availability (rather than prices or messages), it’s a surprisingly powerful and reliable tool for many hosts.
Channel Manager (the paid, professional tool)
A channel manager is software (examples: Guesty, Hostaway, Smoobu, Lodgify, Hostfully, etc.) that acts as a central hub for all your listings.
- You connect all your platforms once through the channel manager.
- It keeps calendars, rates, availability, and bookings in real-time, two-way sync.
- A booking on any site instantly updates everything else, including pricing and inventory.
- Many also handle messaging, automated messages, dynamic pricing, reports, and multi-property management.
- You manage everything from one dashboard instead of logging into each platform separately.
Best for: Owners with multiple properties, higher booking volume, or anyone who wants fewer headaches and better control.
