Common questions about EDI standards

What is EDI standard?

B2B documents, such as purchase order, dispatch advice, or medical claim, must comply with predefined formats. When any two business partners exchange EDI documents, the stringent formats these EDI messages adhere to allow both ends of the B2B channel to understand and interpret the data automatically and accurately.

There are multiple EDI standards, the most prominent being X12 and EDIFACT, and the many sub-standards based on them, such as HIPAA X12 or EANCOM EDIFACT. All EDI standards have an official governing body, like ASC for X12 and UN for EDIFACT, which maintains the standard and defines the specification of each business document.

All EDI specifications are distributed as guidelines (or mappings) in various ways, open or per paid subscription, and in different media, such as text files, pdf files, html files, SEF files, etc.

Do the models match the EDI guidelines?

Yes, all models match the official EDI implementation guidelines to the letter. We've taken all existing guidelines in the multitude of file formats they are available and converted them to a unified set of specifications, regardless of their EDI standard, agency, origin or version.
