Electronic data interchange (EDI) is a system for exchanging business documents electronically between companies, using a standardized format. It replaces traditional paper-based methods, making transactions like purchase orders, invoices, and shipping notices faster and more efficient. By automating these processes, businesses cut down on manual work, reduce errors, and make things run more smoothly.

What is the difference between EDI and email?

EDI and email both enable communication, but they’re pretty different:

  • Automation vs. manual process: EDI automates data exchange, so there’s less need for human input. Email still requires people to manage and enter the data manually.
  • Standardization: EDI follows strict industry standards (like ANSI X12, EDIFACT), making communication seamless. With email, the format can vary depending on the sender.
  • Security & compliance: EDI transactions are encrypted and meet industry standards for security and compliance. Email, though, can be risky and doesn’t have those built-in protections for business use.
  • Speed & accuracy: EDI exchanges data quickly and accurately. Email often requires more steps—like interpreting and entering data—which can introduce errors.

What are the three types of electronic data interchange (EDI)?

EDI comes in three main types, each designed for different needs:

  • Direct EDI (point-to-point): A direct connection between two businesses, using secure communication protocols. This is common among large companies with established partnerships.
  • EDI via value-added network (VAN): A third-party provider handles the data exchange between businesses securely.
  • Web EDI: A web-based system where businesses can send and receive EDI documents through an online portal. It’s easy to use, with less complicated infrastructure.

What is EDI used for?

EDI is widely used across various industries to simplify business transactions. Some common uses include:

  • Retail & supply chain management: Retailers use EDI to handle purchase orders, invoices, and shipments, which helps keep inventory in check.
  • Healthcare: Hospitals and insurance companies exchange patient records, claims, and payment details securely.
  • Manufacturing: Suppliers and manufacturers use EDI to process orders, invoices, and shipments quickly and accurately.
  • Finance & banking: Banks use EDI to handle payments, transfer funds, and manage financial reports.
  • Transportation & logistics: Shipping companies rely on EDI for booking shipments, tracking deliveries, and processing payments.

What is an example of EDI in action?

Here’s how EDI works in retail:

  1. A retailer notices their stock is running low and automatically sends an EDI purchase order (PO) to a supplier.
  2. The supplier gets the PO and sends back an EDI order confirmation and invoice.
  3. When the order ships, the supplier sends an EDI advance shipping notice (ASN) with tracking details.
  4. The retailer receives the shipment and processes the payment using EDI.

Everything happens digitally—no paper, emails, or phone calls. EDI speeds things up, reduces errors, and makes everything more accurate. It’s an essential tool for any business that wants to stay efficient.
