What is

Invoice

An invoice is a commercial document issued by a seller to a buyer, indicating the products, quantities, and agreed prices for products or services the seller has provided the buyer. It is a formal request for payment from the buyer according to the agreed terms of the sale. In e-commerce or marketing, invoices are typically generated electronically and are used for record-keeping and financial transactions. They serve as a legal document that outlines the details of the transaction and ensures that both the seller and buyer are in agreement on what was purchased and the cost of the purchase.
