A sales receipt is a document provided by a seller to a buyer after a purchase is made. It serves as proof of the transaction and typically includes details such as the date of purchase, items bought, prices, and the total amount paid. Sales receipts can be printed or sent electronically. Sales receipts are important for both customers and businesses. For customers, they help keep track of expenses and can be used for returns or exchanges. For businesses, sales receipts are essential for accounting and inventory management, ensuring accurate financial records.
