The standard commission rates for booking.com are 15% in fact. There are ways to push that up due additional marketing (preferred status takes it to to 18% and had requirements on average review scores last I checked). So I don't know where you're getting your impression from that booking charges more than those 15 percent, but you may wish to recheck your numbers. Can't comment on ease of use on the supplier side. Source: I know that because I used to work there, ran the infrastructure eng and prod teams.
