PREPARATION OF BILL-
In order to make up our daily needs, we purchase things from the market. When we buy
something from a shop ,the shopkeeper makes a record of the articles we buy, the rate
of each article, the cost of each article and the total price etc on a slip of paper that is
called as Bill or Cash Memo.
