Electronic invoicing

Electronic invoicing (also called e-invoicing or einvoicing) is a form of electronic billing. E-invoicing includes a number of different technologies and entry options and is usually used as an umbrella term to describe any method by which a document is electronically presented from one party to another, either for payment or to present and monitor transactional documents between trade partners to ensure the terms of their trading agreements are being met. These documents can include invoices, purchase orders, debit notes, credit notes, payment terms, payment instructions, and remittance slips.
