Cool Facts
Proof of purchase. A receipt is a document that shows you bought something and received it. It's like a promise that the transaction happened and you got what you paid for.
Always has a date. Every receipt must show the date you made the purchase. This helps you remember when you bought something and proves how recent or old the transaction was.
Shows the total cost. A receipt lists how much money you gave for your purchase. If there's a sales tax, it gets added to the price and shown on the receipt so you know the exact amount you paid.
Stores use them. When you buy something at a shop or restaurant, they give you a receipt. Stores keep track of their sales this way, and you get proof of what you bought in case you need to return it later.
