What is Electronic Data Interchange?

Electronic Data Interchange (EDI) is a digital exchange between business documents. Instead of mailing, emailing, or faxing paper documents like purchase orders, invoices, shipping notices, or receipts, businesses use EDI to send this information directly from one computer system to another. This process eliminates the need for manual data entry, reduces errors, speeds up transactions, and improves overall efficiency. For example, a retailer can automatically send a purchase order to a supplier, who then responds with an electronic invoice and shipping confirmation—all without printing or scanning anything.

EDI is commonly used in industries like retail, logistics, manufacturing, healthcare, and finance where companies regularly exchange large volumes of standardized documents. It helps businesses save time, cut costs, and ensure smoother communication with partners and suppliers.

EDI Implementation

Implementing Electronic Data Interchange (EDI) in your business involves a step-by-step process that ensures your systems can send and receive standardized digital documents securely and accurately. Here’s how you can implement it:

  1. Assess Your Needs
    Identify which business documents (e.g., purchase orders, invoices, shipping notices) you want to exchange electronically, and which trading partners (customers, suppliers, logistics companies) support or require EDI.
  2. Choose the Right EDI Solution
    You can either:
    • Use an in-house EDI system, where you manage and host everything.
    • Use a third-party EDI provider (like a cloud-based service or Value Added Network/VAN), which is easier for small to medium businesses.
  3. Select an EDI Standard and Format
    Decide which EDI standard (e.g., ANSI X12, EDIFACT) you and your partners will use. This ensures both systems understand the format of the documents.
  4. Integrate EDI with Your Business Systems
    Connect your EDI system to your internal software—like your ERP, accounting, or inventory systems—so the process is automated from input to delivery.
  5. Map Your Documents
    Document mapping translates your internal data format into the EDI standard format and vice versa. This step is crucial for accurate communication between systems.
  6. Test with Trading Partners
    Before going live, exchange test documents with each partner to make sure the system is working correctly, with no data mismatches or formatting issues.
  7. Go Live and Monitor
    Once testing is successful, start full production. Continuously monitor transactions, maintain logs, and address any errors or exceptions promptly.
  8. Maintain and Scale
    As your business grows, you can add more trading partners, automate more document types, or scale to more sophisticated integrations.
