Free Invoice Generator

An invoice is a document sent by a seller to a buyer requesting payment for goods or services delivered. It lists the items, quantities, prices, payment terms, and due date. Invoices serve as a formal record of a transaction and are essential for accounting and tax purposes.

A purchase order (PO) is created by the buyer before goods are delivered. It authorizes a purchase. An invoice is created by the seller after goods or services are delivered. It requests payment. The PO number is often referenced on the invoice to link the two documents together.
