I did this once with Denny's. Woke her up with breakfast I "just made".
Almost got away with it too until she found the receipt. Learned that day to never commit a major crime and then attempt to cover my tracks cause I'll definitely get caught.
Or don't create it. You don't need invoicing or books for an illegal business. Just have a rough idea of what your going to make and make sure you're close at the end of the month. Bookkeeping is just evidence for the prosecution. Its their job to figure out how long you've been in the game. The less they know the better your parole.
