Types of EDI


There are many types of EDI methods organizations will use to enable EDI across their trading community.

Electronic data interchange (EDI) is one of the most common forms of structured electronic exchange of business documents between organizations. 

More than 85% of all electronic business transactions take place using EDI. EDI is used in industries including retail, banking, high-tech, manufacturing, and services. 

8 Types of EDI Solutions
  • Direct EDI/Point-to-Point
  • EDI via AS2 
  • EDI via SFTP
  • EDI via FTPS
  • EDI via Value Added Network or EDI Service Provider
  • Cloud EDI
  • EDI Outsourcing 
  • Integrated EDI
1. Direct EDI/Point-to-Point


Direct EDI, sometimes referred to as point-to-point EDI, establishes a single connection between two business partners. In this approach, a business would connect with each of its business partners individually. Typically large corporations that have business partners with whom they exchange a high volume of EDI documents will choose this method.

While Direct EDI provides more control for each business, it can become very complex quickly. Different EDI trading partners often use separate EDI communication protocols which means you need to support each available option.

With the direct connection model, you will need to purchase a software package that enables you to use all the agreed-upon protocols, such as

2. EDI via AS2 (Applicability Statement 2)


AS2 stands for Applicability Statement 2. Easily described as a business-to-business connection in a point-to-point manner via the web. AS2 is one of the most popular methods for transporting EDI data securely and reliably used by millions of businesses, including most major retailers, such as Amazon and Walmart.

3. EDI via SFTP (Secure File Transfer Protocol)

SFTP stands for Secure File Transfer Protocol, also called SSH File Transfer Protocol, and is a network protocol for accessing, transferring, and managing files on remote systems. SFTP provides organizations with a higher level of file transfer protection which allows businesses to securely transfer billing data, funds, and data recovery files.

4. EDI via FTPS (File Transfer Protocol)

FTPS stands for File Transfer Protocol Secure which is an extension to the commonly used File Transfer Protocol. In FTPS, FTP data travels through the network using either Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols.

5. EDI via Value Added Network or EDI Services Provider

EDI VAN (Value Added Network) - Commport Communications

The majority of EDI exchanged today occurs through EDI Value-Added Network (VAN). As long as two organizations are using the same VAN, communication is possible regardless of which EDI protocol is used to transfer information. Unlike Direct EDI this means organizations can manage one connection with the EDI VAN instead of separate lines of communication with each potential partner. Many businesses prefer this model to save them from the ongoing complexities of supporting the varying communication protocols required by different business partners.

How it Works

An organization will be provided with a virtual mailbox by the EDI VAN provider. From there documents are sent and received. A trading partner retrieves messages by connecting to the VAN, which validates the message and verifies the recipient’s identity. It then provides a full audit trail, and all messages are tracked and accurately recorded.

Benefits of Value Added Network (VAN)
  • 1. Error correction
  • 2. Improved exchange
  • 3. Secure
  • 4. Standardized
6. Cloud EDI
