An invoice is generated, when a service or product is contracually agreed with a client. Both parties are bound to the mutually agreed duties. The prerequisite for the service or product is a purchase order. With the invoice the seller addresses his demand to his client. Another word that can be used for an invoice is a bill.

An invoice has several parts.

• Information about the seller (name, address, banque account, tax-number)
• Information about the transaction (description, date and content of delivery)
• Information about the bill (invoice number, date of the invoice, order number)
• Payment terms (amount, taxes, total amount of the invoice, when to pay, where to pay to)

Invoices can be paperbased or electronical. Especially in electronic commerce electronic invoices are transfered. EDI standards, as the UN-standard EDIFACT for administration, commerce and transport is to be used.
