Hope this helps you:  In English speaking countries, the term most frequently applies to the printed record given to a consumer at the point of sale which lists the purchases made and the prices including tax, discounts and other adjustments, the amount paid, and the method of payment. The receipt may also include messages from the retailer, warranty or return details, special offers, advertisements or coupons. Receipts may also be provided for non-retail operations such as banking transactions. A receipt is a legal document.[1] In many countries, notably the United States of America, it is mandatory by law for retailers, and individuals, have to show receipts and store information about every receipt, so that the tax authority, or IRS can check that sales are not hidden.[2]
