With Hotel Sync Channel Manager you can forget about overbookings and simply synchronise your calendar with online travel agencies.
Reservations made through online travel agencies will automatically sync to Hotel Sync, and Hotel Sync will close booked periods on other channels. Also, you will manage all your rates through Hotel Sync.
By modifying rates, availability or minimum stay in Hotel Sync, we will sync these changes to all connected channels.
Entering private reservations to Hotel Sync also decreases availability on connected channels.
