Generally speaking, an invoice is a commercial instrument issued by a seller to a buyer. It identifies both the trading parties and lists, describes, and quantifies the items sold, shows the date of shipment and mode of transport, prices and discounts, if any, and delivery and payment terms. In certain cases, an invoice serves as a demand for payment and becomes a document of title when paid in full.
