Theory:

We can not create or produce everything we want. In such cases, we go shopping for things. If we observe, once we make the payment at the cash counter, the shopkeeper hands out a piece of paper containing the list of items we have bought and a few numbers next to each of them. This piece of paper is called the bill.
A bill is a written document or a printed document. It acts as a proof of the payment made or received during a business transaction.
