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 purchases for warranty claims or budgeting purposes. Many businesses use receipts as part of their accounting processes to manage sales and inventory effectively.
