What Is Electronic Data Interchange?

Electronic Data Interchange (EDI) is the computer-to-computer exchange of business documents in a standardized electronic format. It replaces traditional paper-based methods of communication—such as mail, fax, or email—with a streamlined digital process.

EDI's roots go back to the 1960s, when Ed Guilbert developed an electronic communication system for U.S. Army supply chains. Since then, EDI has become an indispensable tool across various industries, from retail and manufacturing to healthcare and logistics.

EDI is a methodology that enables the seamless exchange of business documents between different computer systems without human intervention. It works by translating business documents into a standardized format that can be read and processed by any EDI-enabled system.

For instance, when a retailer sends a purchase order to a supplier, their EDI software converts the order into a standardized EDI format. This formatted document is then transmitted electronically to the supplier's system, where it's automatically received, interpreted, and processed.

This automation eliminates the need for manual data entry, significantly reducing processing time and the potential for errors.

The EDI System

A typical EDI system consists of several key components:

  1. EDI Software: This is the engine that translates, validates, and processes EDI documents.
  2. Communication Protocols: These are the rules and methods for transmitting EDI data.
  3. EDI Standards: These are the agreed-upon formats for organizing electronic documents, helping ensure that all parties can understand the information being exchanged.
  4. Trading Partners: These are the organizations exchanging EDI documents with each other.

EDI standards play a crucial role in maintaining compatibility between different systems. The most widely used standards include UN/EDIFACT (United Nations Electronic Data Interchange for Administration, Commerce, and Transport), popular internationally, and ANSI X12, predominantly used in North America.

The EDI Process

The EDI process involves several key components that drive an automated end-to-end workflow.

  1. Data Extraction: Information is pulled from your company's internal systems.
  2. Translation: The data is converted into a standardized EDI format.
  3. Transmission: The formatted data is sent to the recipient via secure channels.
  4. Receipt and Integration: The recipient's system receives, translates, and integrates the data.

Different Types of EDI

As EDI has evolved, several methods have emerged to suit various business needs and technological capabilities. The three main types of EDI are Direct EDI (Point-to-Point), EDI via Value-Added Networks (VANs), and Web EDI. Each has its benefits.

  1. Direct EDI (Point-to-Point): Direct EDI establishes a direct connection between trading partners' computer systems to exchange EDI documents. It offers fast, secure communication but can be complex and costly to set up and maintain, especially when dealing with multiple trading partners.
  2. EDI via Value-Added Networks (VANs): VANs act as intermediaries, providing a secure, hosted cloud environment for EDI document exchange. This model simplifies the process of connecting with new partners and often provides additional services such as data backup and transaction monitoring.
  3. Web EDI: Web EDI is a browser-based solution that makes EDI accessible to smaller businesses or those with lower transaction volumes. Users can create, send, and receive EDI documents through a web interface without specialized EDI software.

Common (and Uncommon) EDI Documents and Transaction Sets

EDI facilitates the exchange of a wide variety of business documents, each represented by a specific transaction set. Some of the most common include Purchase Order (EDI 850), Invoice (EDI 810), Advanced Shipping Notice (EDI 856), and Functional Acknowledgment (EDI 997), which confirms receipt of an EDI transmission.

EDI also handles less common transaction sets, including:

  • Request for Routing Instructions (EDI 753): This transaction set is used to request routing instructions for shipments. It helps optimize transportation planning and execution by providing general information about merchandise that's ready to ship.
  • Procurement Notices (EDI 836): These notices provide the format and data contents for notifying the award or pending award of a contract, including indefinite features like delivery schedule and quantities.
  • Order Status Report (EDI 870): This report provides detailed information about the status of purchase orders, including acknowledgments, changes, and cancellations.

In other words, whatever your company’s industry or niche, EDI is applicable and provides value, as we’ll see in the next section.

What Are the Benefits of EDI?

Companies worldwide face mounting paperwork, data entry errors, delayed shipments, inventory discrepancies, and strained partner relationships. EDI addresses these pain points head-on, offering a range of benefits that can transform how your business operates and interacts with its partners.

These transformative benefits have led the world's largest brands–from retail giants like Walmart and Amazon to automotive leaders like Toyota and Ford–to mandate EDI usage across their supply chains.

Let's delve into the key benefits that make EDI an indispensable tool in modern business:

Efficiency and Speed

With EDI, manual processes that once took days can be reduced to automated workflows that take seconds. Data entry, validation, approvals, printing, and mailing can be eliminated. This dramatic increase in speed lets your business operate 24/7 and take advantage of early payment discounts, which are offered by 65% of vendors (according to research from the Institute of Finance and Management).

Accuracy

Human error in manual data entry can be costly. A misplaced decimal point could result in an order for 10,000 items instead of 100, leading to overstocking, wasted resources, and potential conflicts with trading partners.

EDI eliminates these errors by removing manual data entry from the equation. Built-in validation checks helps ensure data is complete and in the correct format before transmission. This improved accuracy cascades through the entire supply chain, reducing disputes, returns, and canceled orders while preserving valuable business relationships.

Cost Savings

By eliminating paper-based processes, your business can save on printing, postage, and storage costs. The average cost of processing an invoice, for example, which is estimated to be somewhere between $15 and $40 per invoice, is lowered to mere pennies. Reducing manual labor allows staff to focus on higher-value tasks, improving overall productivity. Moreover, the increased accuracy leads to fewer chargebacks, returns, and resolution costs.

Data Security

EDI offers a level of security that far surpasses traditional document exchange methods. Transmissions are typically encrypted and require authentication, protecting sensitive information from unauthorized access. With EDI, you don’t have to worry about documents being lost or damaged––all of your electronic records are backed up automatically and accessible through a simple “Google-like” search box.

Decision-Making

EDI systems make storing, accessing, and analyzing transaction data easier, giving your business access to invaluable insights. You can track every step of your supply chain in real time, identify bottlenecks, and optimize inventory levels with precision.

Sustainability

EDI adoption allows companies to significantly reduce their carbon footprint by eliminating paper use. Enhancing sustainability can strengthen your brand and prepare you for future regulations in our increasingly eco-conscious world.

EDI Integration with ERP

To truly leverage the power of EDI, it must be integrated with your company's existing business systems. This integration allows for seamless data flow, further automation, and enhanced visibility across your entire organization.

ERP integration is crucial for most companies and seamless with advanced solutions like Epicor. It enables automatic record creation and updates from incoming EDI documents––and automatic generation of outgoing EDI documents from ERP data. Without integration, manual data transfer between systems negates the primary benefits of EDI.
