A lot of our users use a PMS to maintain a centralized calendar that syncs to all the different channels. Since we integrate into many of these PMSs, we update prices to the PMS calendar, which in turn updates them to all the different channels. You can even setup channel-specific commission rates on most PMSs.
If you connect certain channels through a PMS, but the others directly (or through another PMS/channel manager), we have the capability for you to ‘map’ the two listings of the same property together so that our price recommendations are always in sync. A lot more detail on that can be found here
