What is EDI?

Electronic data interchange (EDI) is the automated, computer-to-computer exchange of business documents in a standardized electronic format. EDI replaces traditional communication methods—such as faxes, emails, and postal mail—allowing businesses to exchange critical data quickly, securely, and accurately.

EDI enables the automated exchange of documents between organizations, facilitating everything from purchase orders and invoices to shipping notices and payment documentation.

How does EDI work?

EDI enables direct system-to-system communication using structured data formats. This automation eliminates many time-consuming manual processes, resulting in significantly reduced costs, accelerated processing times, and minimized errors in document handling.

EDI works by translating business documents into a standardized electronic format that can be easily read and processed by computers. Here's how the process typically works:

• Document preparation: A business creates a document (e.g., a purchase order) using its internal system, such as an ERP or accounting platform.
• Data conversion: The document is converted into an EDI format (e.g., ANSI X12, EDIFACT) using EDI translation software.
• Transmission: The EDI document is securely transmitted to the recipient over a value-added network (VAN) using either a managed services provider, or via a direct connection.
• Processing and integration: The recipient's system receives the EDI document and translates it into a compatible format before automatically populating their internal system.

By automating these steps, EDI eliminates the need for manual data entry, reduces human error, and accelerates the exchange of information.
