A receipt is a document that serves as proof of a transaction between a buyer and a seller. It typically includes details such as the date of purchase, items bought, prices, and the total amount paid. Receipts can be printed or digital and are often provided after a purchase in stores, restaurants, or online. Receipts are important for various reasons, including tracking expenses, returning items, and filing taxes. They can also help consumers keep records of their spending habits. Many businesses use receipts to manage inventory and sales records, making them essential for both customers and retailers.
