A receipt is a document that proves a purchase has been made. It usually includes details like the date, items bought, prices, and the total amount spent. Receipts are important for keeping track of expenses and can be used for returns or exchanges. They often come from stores, restaurants, or online purchases. Many people keep receipts for budgeting purposes or to claim expenses for work. Some receipts are printed on paper, while others are sent electronically via email or apps. In some cases, receipts can also help with warranties for products, ensuring that you have proof of purchase if something goes wrong.
