Sirvoy is available in two versions:
This version covers all the essential features, as long as you don’t need to connect to any booking channels. Sirvoy Starter is a powerful PMS and booking engine which keeps track of, and administrates all your hotel bookings, guests, cleaning, administration, online payments, automated text messages and emails etc.
If you want to connect with booking channels, this is the right choice. Sirvoy has direct connections with most of the major booking channels. The Pro version also supports the iCal format, which means you can connect with airbnb, FlipKey, etc. If you still want more channels, you can connect with third-party channel managers (myallocator and SiteMinder).
In addition to that, Sirvoy Pro also allows you to categorize your room types and to create multiple user accounts as well as multiple booking engines.
