This specification provides the definition of the Commercial account summary message (COACSU) to be used in Electronic Data Interchange (EDI) between trading partners involved in administration, commerce and transport.

A commercial account summary message enables the transmission of commercial data concerning payments made and outstanding items on an account over a period of time. The message may be sent at specific agreed fixed intervals or on demand, and may be sent to and, or, from trading parties and, or, their authorised agents.

The Commercial account summary message may be used for both national and international applications. It is based on universal practice related to administration, commerce and transport, and is not dependent on the type of business or industry.

A commercial account summary may:

• refer to invoices, credit notes, debit notes, or payments over a period of time.
• refer to only one account, in one currency.
• be initiated at any time by a party, depending upon agreement between the parties involved.
• provide information on an account over a period of time. When the message is used in this way both payments made and amounts outstanding may be detailed.
• may contain additional information for customs and/or statistical purposes/services.
• be used as a reminder of payment due for the current accounting period.
• be used as a request for payment of outstanding invoices and detail penalties for amounts outstanding from previous accounting periods.
• be used in the reconciliation of accounts when detailing payments made.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 1.

See UNTDID, Part 4, Chapter 2.3 UN/ECE UNSM - General Introduction, Section 2.

This section should be read in conjunction with the segment table which indicates mandatory, conditional and repeating requirements.

The following guidelines and principles apply to the whole message and are intended to facilitate the understanding an implementation of the message:

Where a choice of code or text is given only the code element should be used wherever possible.

Conditional data that is not required in the message should not be included.

Care must be taken that the segment qualifier in dependent segments do not conflict with the segment qualifier of the trigger segment of a group.

Free text information within the message should be avoided as this inhibits automatic processing. It is only used when additional information that cannot be accommodated within the other segments is required.
