Computer invoicing: Procedures for testing EDI invoicing systems: Standard Procedures

Examine systems/EDI message documentation (and/or ask trader) to determine:

  • The extent of work that has already been undertaken - for example, the extent of trading, partners identified (who are they?), is the system at the trialling stage or still developing?
  • The EDI invoice message standard (TRADACOMS, SMMT/ODETTE, EDIFACT or other) and check that the version in use is in line with departmental requirements
  • EDI translation/deformatting, for example in-house standard to EDI standard and vice versa - what software is used, for example an EDI enabling package, Interbridge or in-house software?
  • Control procedures, especially in relation to departmental requirements.
