EDI Transactions & EDI Integration: A Step-by-Step Manual for Seamless Operations

Electronic Data Interchange (EDI) is a structured method by which businesses can transmit data electronically from one business system to another, using standardized message formats. 

This process facilitates the computer-to-computer exchange of purchase orders, invoices, shipping notices, and many other types of business documents. 

In simpler words — think of EDI as a translator that allows different systems and applications across multiple platforms to communicate seamlessly. 

Key Components of an EDI System

• EDI Software. This is the application that translates data from a company’s internal system (like purchase orders and invoices) into the standardized EDI format and vice versa. It can either be hosted on-premises or accessed via cloud services.

• Translation Software. Works hand-in-hand with EDI software to convert business documents into EDI formats and interpret incoming EDI files into a readable format for the business system.

• Communication Network. This serves as the pathway for transmitting EDI data between trading partners. The most common include Value Added Networks (VANs), Direct EDI (also known as point-to-point), AS2, FTP/Secure FTP, and increasingly, APIs. 

• EDI Standards. These are the rules governing the structure and format of the EDI documents that ensure consistency across all exchanges. Common standards allow for interoperability between different systems and organizations. 

• Integration Layer. This component integrates the EDI system with the internal applications like Enterprise Resource Planning (ERP) systems, accounting software, and inventory management systems, allowing for automatic data input and retrieval.

• Data Mapping Tools. These tools help in mapping the data fields in the company’s internal format to the corresponding fields in the EDI standard format. 

Types of EDI Standards

• ANSI X12. Mostly used in North America, this standard is flexible and can handle data relating to various industries including finance, healthcare, transportation, and more.

• EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport). This is an international standard more prevalent outside of North America. It is used by organizations within the United Nations and covers a wide range of industries globally.

• TRADACOMS. Primarily used in the UK retail sector, it is an older standard and has been largely replaced by newer standards but is still in use for certain legacy systems.

• GS1 EDI. Developed by the global standards body GS1, this set of EDI standards is used in global supply chains, particularly in retail and healthcare, for transactional documents like orders, invoices, and logistics commands. 

EDI Workflow: How EDI Integration Works

• Document Preparation. The first step in an EDI workflow involves preparing the business documents that need to be sent. These could be purchase orders, invoices, shipping notices, or any other type of business communication. 

• Document Translation. Once the data is collected, it must be converted into an EDI format. Companies often use EDI translation software to convert their internal data format into an EDI standard format that can be understood by the receiving party. Common standards include EDIFACT, X12, and XML. 

• Transmission. The EDI documents are then transmitted to the partner. This transmission typically occurs through one of several methods such as Direct EDI (Point-to-Point), EDI via VAN, or EDI via AS2/FTP which are secure Internet protocols. 

• Receipt and Translation. The receiving party obtains the EDI document. Their EDI software translates the standard EDI format into a format that their internal systems can process.

• Acknowledgement. Often, the recipient sends back an acknowledgment document (like an EDI 997 functional acknowledgment in X12), confirming that they have received and successfully processed the EDI document. Both parties might use reports and dashboards to monitor EDI transactions and manage exceptions or errors in processing. 

• Processing. Finally, the document is processed accordingly, triggering business processes such as order fulfillment, invoice payment, or inventory updates.

Practical Example: A Retail Chain Ordering Stock from Suppliers

Let’s take a practical example of EDI in the retail industry to illustrate how businesses use it in their day-to-day activities:

Stage 1: Purchase Order Creation

• A retail store chain determines that its inventory of a particular product is low. The store’s inventory management system automatically generates a purchase order (PO) based on predefined stock levels. 

• The PO is then formatted into an EDI document, specifically an EDI 850 (Purchase Order), using the store’s EDI software. 

Stage 2: Sending the Purchase Order

• The EDI 850 document is transmitted to the supplier via a secure EDI network. The retail chain uses AS2, a common EDI protocol, to send this information securely over the internet. 

Stage 3: Order Acknowledgment by Supplier

• Upon receiving the EDI 850, the supplier’s EDI system uses translation software to convert the EDI format into a format their order management system can process.

• The supplier’s system automatically checks product availability and generates an EDI 855 (Purchase Order Acknowledgment), which is sent back to the retailer, confirming receipt and acceptance of the order. 

Stage 4: Shipping the Goods

• The supplier prepares the ordered goods for shipment. Once the goods are shipped, the supplier sends an EDI 856 (Advance Shipment Notice) to the retailer. This document provides detailed information about the shipment contents and expected delivery timing. 

• The retailer’s system automatically updates the expected inventory levels and prepares for receiving the shipment. 

Stage 5: Invoicing and Payment

• Upon receiving the goods, the retailer’s EDI system matches the shipment against the original EDI 850 and EDI 856 to ensure that the shipment is correct and complete.

• The supplier sends an EDI 810 (Invoice) to the retailer for the goods shipped. The retailer’s financial system processes the invoice and, after confirmation, executes payment through an EDI 820 (Payment Order/Remittance Advice), completing the transaction cycle.

How to Set Up EDI Integration 

Step 1: Assess Your Requirements

• Determine what kind of data you will be exchanging (e.g., invoices, purchase orders, shipping statuses), with whom (e.g., suppliers, customers) and the frequency (daily, weekly, or monthly).
  • Some relationships might require real-time data exchanges, while others might be on a daily or weekly batch basis. 

• Look at your current transaction volumes by analyzing internal records or ERP data. Identify peak times and average data loads to understand what your EDI system will need to handle. 

💡 Pro Tip → Develop a comprehensive template that lists all potential EDI transactions and their attributes (e.g., mandatory, optional, conditional fields). This will help when configuring your EDI system to meet these specifications.

Step 2: Choose an EDI Format

• Select EDI standards that fit your trading partner needs — and most importantly, your industry and region.
  • For example, the healthcare sector in the US might use X12 because of specific requirements under HIPAA regulations, while international trade might lean towards EDIFACT. 

• List all the types of documents you currently exchange with partners and identify their EDI equivalents. Common EDI Shipping documents include invoices (EDI 810), purchase orders (EDI 850), and advance ship notices (EDI 856). 

💡 Pro Tip → If your partners use different EDI standards, consider implementing a flexible EDI software or service that can handle multiple formats easily. This flexibility can save time and reduce errors in the long run.

Step 3: Select an EDI Integration Method

• Direct EDI/Point-to-Point. This allows for faster data exchanges and more control over the communications process. This can be beneficial for handling sensitive or large-scale transactions where timing and data integrity are crucial. 

• EDI via VAN. VANs simplify the EDI process by managing the complexities of data exchange for you. This can be especially beneficial for businesses without the resources to manage their own EDI infrastructure. 

• EDI Integration Service Providers. Many service providers offer cloud-based EDI solutions, which can provide scalability and flexibility without the need for substantial initial hardware investment.
  • These providers typically offer integration capabilities with your existing ERP systems, automating data flow between systems and reducing manual data entry errors. 

💡 Pro Tip → Before fully committing to a particular integration method, conduct a pilot test with a few key partners. This allows you to assess the practical implications of the method, including setup complexity, reliability of data exchange, and overall impact on your business operations.

Step 4: Set Up EDI Infrastructure

• In-house vs. Outsourced. Decide if you want to manage your EDI in-house or outsource it to a service provider. In-house requires software installation and hardware setup, whereas outsourcing simplifies the technical complexity.
• Install the EDI software and configure it according to your chosen standards and formats. This includes setting up communication protocols and integrating with your internal systems (like ERP or accounting software). 

💡 Pro Tip → If integration between EDI software and your internal systems proves complex, consider using integration middleware. Middleware can act as an intermediary layer that helps translate and transfer data seamlessly between different formats and systems.

Step 5: Conduct Partner Onboarding

• Develop comprehensive documentation that includes all your EDI requirements, specifications, and standards.
  • This should cover data formats, communication protocols, and any other technical specifications that your partners will need to know. 

• Establish dedicated communication channels for EDI queries. This could be through a designated support email, a hotline, or a web portal where partners can get assistance and updates on the EDI process. 

💡 Pro Tip → Organize workshops or training sessions for your partners, especially if they are less familiar with EDI. These sessions can help clarify the technical requirements and processes, ensuring that everyone is on the same page and reducing the likelihood of errors during the initial exchanges.

Step 6: Test and Validate EDI Transactions

• Exchange test documents with trading partners to ensure compatibility and accuracy. 

• Conduct end-to-end testing with your partners to ensure that the entire EDI process, from data entry through to final processing in your internal systems, works as expected.  

• Verify that data is correctly translated and processed by both your systems and your partners’ systems. 

• After each testing phase, gather feedback from your partners on any issues they encountered and any difficulties with the process. 

Step 7: Transition to Live Environment

• Consider implementing a phased rollout where you begin by sending only a subset of your EDI transactions or start with less critical partners. 

• Set up real-time monitoring tools that can alert you to transaction errors or delays as they occur. This allows for immediate intervention to resolve issues before they impact business operations. 

💡 Pro Tip → Utilize EDI transaction management tools that provide dashboards and analytics to monitor the health and performance of your EDI exchanges. These tools can help identify patterns in errors and guide optimization efforts.

Step 8: Maintain and Optimize

• Establish a regular schedule for conducting comprehensive audits of your EDI system’s performance. These audits should examine all aspects of the system, including data accuracy, transaction speed, and compliance with both internal standards and external regulations. 

• Compare your system’s performance against industry standards or benchmarks to evaluate its efficiency. This could involve metrics like the error rate in transactions, the time taken for transaction completions, or the percentage of transactions processed without manual intervention. 

💡 Pro Tip → Utilize advanced data analytics to mine EDI transaction data for insights that can drive optimization efforts. Analytics can reveal patterns in data usage and transaction flows that are not evident through casual observation. For example, data mining can identify recurring bottlenecks in data processing or typical errors that occur with certain types of transactions.

Types of EDI Integration

Direct EDI (Point-to-Point)

Direct EDI (Point-to-Point) involves businesses transmitting documents directly to each other without intermediaries. 

This type of EDI typically uses secure Internet protocols, such as FTP (File Transfer Protocol), SFTP (Secure File Transfer Protocol), or AS2 (Applicability Statement 2), to establish a direct connection between the trading partners’ systems. 

How it works:

Both trading partners establish and configure their EDI systems to communicate directly with each other. This involves setting up the necessary software, choosing a communication protocol, and agreeing on the EDI standards and formats to be used (e.g., EDIFACT, X12). 

• Pros. Direct EDI allows businesses complete control over their EDI processes and data, with increased security since data is transmitted directly between the parties without passing through third-party networks. 

• Cons. As the number of trading partners increases, managing individual connections can become increasingly complex and inefficient. Each new partner potentially requires a separate setup and maintenance process.

Recommendation: Direct EDI is often best suited for businesses with a stable set of trading partners where large volumes of data are exchanged regularly, and both partners have the capability to support the technical requirements. 

EDI via VAN (Value-Added Network):

This method uses a third-party network (VAN) that acts as an intermediary to facilitate the exchange of EDI messages between trading partners. VANs handle the complexities of data transmission, including security, compliance, and message tracking. 

How it works:

Both trading partners subscribe to a VAN service and set up their connection to the VAN, which involves configuring their EDI systems to send and receive documents through the VAN.

• Pros. in terms of scalability, VANs can easily handle increases in EDI volume or changes in requirements without significant changes to the user’s existing systems.

• Cons. Using a VAN can be more expensive than direct EDI, as it typically involves subscription fees and transaction costs.
