From what I could find on Google an international bill of exchange is: "a written order that one person gives to another person to pay a certain amount of money to a third person. It's like a check, but it can be used in different countries."
Why someone would want to use this to just pay their bills is beyond me, and I don't really care enough to investigate it further.
I assume it's some sort of imaginary SovCit sorcery to try and get away with cheating someone out of money somewhere along the way
