TBG1 Supply Chain
This specification provides the definition of the Invoice message (INVOIC) to be used in Electronic Data Interchange (EDI) between trading partners involved in administration, commerce and transport.
1.1 Functional definition
A message claiming payment for goods or services supplied under conditions agreed between the seller and the buyer.
The United Nations Standard Invoice Message, with correct data qualification, serves also as the specification for Debit Note and Credit Note messages. Throughout this document, the reference to 'Invoice' may be interpreted as conveying the wider meaning of 'Invoice/Credit Note/Debit Note'.
1.2 Field of application
The Invoice 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 seller may invoice for one or more transactions
- An invoice may refer to goods, items or services related to one or more orders, delivery instructions, call-offs, etc.
- An invoice may contain references to payment terms
- An invoice for cross border transactions may contain additional information for customs and/or statistical purposes/services

4. MESSAGE DEFINITION
4.1 Data segment clarification
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 and implementation of the message:
All specified dates/times should be in the format 'ccyymmdd'/'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.
