Electronic Data Interchange (EDI) Standards refer to a set of standardized formats for exchanging business data electronically between different organizations. These standards define the structure, content, and format of electronic messages that are used to exchange information such as invoices, purchase orders, and shipping notifications. EDI standards help to ensure that different systems can exchange data effectively and accurately, and they provide a common language for data communication between trading partners.
