Once again you are introducing confusion, in this case muddying the waters with unstated design questions, confusing a system that is designed to anticipate suppliers and bills with one that isn't. The fact that such misconnections is tolerated by so many is just a reflection of the rampant illiteracy in the western world today. Those people who can't position an English sentence relative to the task at hand are no different from the janitor I knew who wanted the computer to pick tommorow's track winners for him, they are basically incompetent for the task.
