The document sent by suppliers of goods to a prospective buyer, informing him of what to pay if he buys the goods is called an invoice. An invoice is a commercial document that itemizes all the products or services provided by the seller, as well as the prices. It typically includes important details such as the list of goods, quantities, agreed-upon prices, any discounts or taxes, and the total cost that the buyer needs to pay.

Invoices serve multiple purposes: they act as a request for payment, provide a clear record of a sale, and can be used for accounting and taxation purposes. By receiving an invoice, the prospective buyer is informed of the amount they need to pay if they decide to purchase the goods.
