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

A Statement of Account is a communication from a Seller or his agent to a Buyer or his agent, providing information about the status of an account at a specific point in time. It is used as an aid to reconciliation. At the same time it may be a reminder of payment due.

The UN Standard Statement of Account Message may be used for both national and international business. It is based on universal commercial practice and is not dependent on the type of business or industry.

• A Statement of Account may refer to only one account, in one currency.
• A statement of Account contains only outstanding debts and does not specify any debts which have been cleared since the previous Statement.
• A Statement of Account may be initiated at any time by the Seller, depending upon agreement between the Buyer and the Seller.

See UNTDID, Part 4, Chapter 2.6 UN/ECE UNSM - General Introduction, Section 1.

See UNTDID, Part 4, Chapter 2.6 UN/ECE UNSM - General Introduction, Section 2.

This section should be read in conjunction with the Branching Diagram and the Segment Table which indicate mandatory, conditional and repeating requirements.

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

All specified dates/times should be in the format 'yymmdd'/'hhmm' unless all parties involved in the transaction agree that there is a functional requirement for an alternative format. Periods should be specified as whole numbers representing the required period as indicated in the format qualifier (weeks, months, etc.)

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.
