What is an e-commerce transaction broker?

This is where the salesperson doesn't represent either party, but handles the transaction only. This is where the transaction broker AsiaRooms.com's responsibilites lie...i.e. the middleman roles of facilitating search, contract, regulation and maintenance (stages of the transaction cost model). AsiaRooms secure all necessary documentary requirements from the hotel (i.e. the seller of the hotel rooms) for the buyer. AsiaRooms is not responsible to ensure that the hotel uphold its reputations and promised services and cannot be sued if the hotel fails to perform. This is the same with the other transaction brokers like Hotels.com, Accomline.com and Octopus.com".
