Channel Management (also Multi-Channel-Management) refers to the techniques and systems used by hotels in line with their distribution policy. This management method includes content management as well as data reconciliation in various distribution channels. It means the updating of the hotel information, of room rates and availabilities across all distribution channels, such as hotels website, third parties (OTAs, IDS, ADS) and the CRS/GDS.
Effective channel management solutions should improve efficiency by providing a centralise way to control multiple channels.
In other words: Using a Channel Manager is a smart way to save time and avoid errors. There is no need to update dozens of extranets manually, as nowadays you can do that just from one system: Your Channel Manager.
