FrontDesk Master has integrated Channel Manager and the core concept behind it is that whenever you do something to the bookings in the system the updates are immediately and instantly sent to all enabled channels.
First, when you enable the channel, the system will upload your one-year availability and all the restrictions according to what can be seen in Availability & Rate Calendar.
Next, whenever there is a new booking a modification in the booking or when you change the price in the system, block the bed or close the room, FrontDesk Master instantly updates availability and prices to the channels.
