How can I adjust the travel agent commission?

In general it is up to you to assign how many percent of the room rate shall be paid to the travel agents.

We recommend paying 10% travel agent commission as the major hotel chains are paying this amount. For many travel agents this commission is the only income when making a hotel reservation for a client and they certainly prefer to book hotels which give them the bigger share.

Changing the percentage
It is fairly easy to adjust the percentage in the extranet via gds.hoteliers.com:

Go to gds.hoteliers.com
Open Hotel > Addresses
At Marketing, set the percentage and click Save
