You know, I like grep and sed and all that too, but what the hell are you talking about here? The bill command just takes an email on stdin? How's it know which account that email belongs to? From a database? With what credentials? Does it bill to paypal or visa? To which merchant account number? The thing with "unix style programming" fetishism is that, yeah, pipes are great, but now you're writing incredibly complicated options parsers to configure all your little standalone programs. Isn't there a point at which a simple method call is easier? We've had method calls for a long time. The reason you were downvoted (not by me) is probably that people thought this was obvious and you were being obtuse and ideological.
