The business process is the detailed description of the way trading partners intend to play their
respective roles, establish business relations and share responsibilities to interact efficiently with
the support of their respective information systems.
Each Business transaction is realized by an exchange of Business documents (also called
messages). The sequence in which these documents are used, composes a particular instance of
a scenario and are presented as use cases in the document.
The business documents are composed of Business Information Entities (BIE), which are
preferably taken from libraries of reusable business information entities. The contents of the
business documents and the Business Information Entities are presented using class diagrams
and/or requirement lists.

The invoicing process is used to exchange the invoice between the supplier and the customer for
the supply of goods or services ordered, delivered, received, consumed, etc.
This document describes the variants of invoicing in use in trade and industry. It considers the
legal statements and, to a certain extent, the corrections of a previously sent invoice, by using
credit notes or debit notes.
The following functions are part of the invoicing cycle, but so far the treatment of the „Traditional
Invoice‟ and the Self-billing Invoice, with its variants is dealt with at present:
 The treatment of the traditional or suppliers‟ initiated invoice
 The treatment of the self-billing invoice
The invoice described in this document can apart from supplier initiated invoice and the self-billing
invoice also serve as corrected invoice, consolidated invoice as well as credit note or debit note,

depending on the defined function within the business process and the message. Further invoice
related processes, e.g., Dispute note or List of open items, will be developed in the future
The payment and remittance processes are not part of the invoicing process, but are detailed in
the payment process.
To simplify understanding, the parties involved are limited to customer and supplier. In the total
trade business, each of the parties can have more than one role. For the invoicing process, the
customer can act as the customer, the buyer, the consignee, the ealize and the ordering
company. The supplier covers the roles of the seller, the sales agent or sales company, the
consignor, the invoice issuer and payee, if not another party is specified.
To ensure that the invoicing of the ordered, delivered, received or consumed goods or services are
in line with common practice used between trading partners, the following scenarios are used:
 The traditional invoicing, by the supplier to the customer (supplier is acting as the invoice
issuer)
 The self-billing invoicing, by the customer to the supplier (customer is acting as the invoice
issuer.
