An invoice is a document that itemizes a transaction between a buyer/hiring business and a seller/employee.
An invoice will usually include the quantity of purchase, price of goods and/or services, date, parties involved, unique invoice number, and occasionally tax information. If goods or services were purchased on credit, the invoice will usually specify the terms of the deal, and provide information on the available methods of payment.
