Product/Topic: EDIFACT - INVOIC (D.964)
The EDIFACT INVOIC (D.96A) is a United Nations (UN) standard Electronic Data Interchange (EDI) message used to transmit invoice information from a supplier to a buyer. It communicates details for goods or services supplied, including party information, payment terms, tax details, line item information, monetary totals, and settlement information.
