If I make my own bills, what information do I need to have on them? Name, address, phone number.....What I am going to do it make a bill with categories that I'm just going to fill in at the job site. what categories do I need? (amount, date, etc.???) If you guys have any samples that you made I would be glad to look at them I remember some guy posted a bunch of them on here that were perfect for us to use but I can't find it anymore. Thanks alot guys.
