While often confused, a receipt and a ticket serve distinct roles in a transaction. A receipt is a legal document issued after a payment is completed, serving as permanent proof of purchase and a record of the financial exchange; it typically lists the items bought, the total cost including taxes, and the payment method used. In contrast, a ticket is a voucher or permit that grants the holder access to a specific service, event, or location, such as a concert, a movie, or a flight. While a receipt confirms that you paid, a ticket is what you actually present at the door or gate to be admitted. In modern digital systems, you may receive an "e-receipt" via email while your "e-ticket" is stored in a mobile wallet app. For tax and reimbursement purposes, the receipt is the necessary document, whereas for entry and logistics, the ticket is the only item that matters to the service provider.
