Cash Mail and Bank transfers such a good idea?

As a long term webmaster and as the CEO of Hostorea.com I have always thought that accepting cash and doing direct bank transfers was a good idea. However I am not so sure it will work like a charm or if there will be people trying to "take advantage" of our company. However we will stop accepting this sort of payment if things don't go as well as planned. However for now it will be accepted!
