An invoice, bill or tab is a commercial document issued by a seller to a buyer, relating to a sale transaction and indicating the products, quantities, and agreed prices for products or services the seller had provided the buyer. If goods or services were purchased on credit, the invoice usually specifies the terms of the deal and provides information on the available methods of payment. To avoid confusion, and consequent unnecessary communications from buyer to seller, some sellers clearly state in large and/or capital letters on an invoice whether it has already been paid.
