Electronic Data Interchange (EDI) is the electronic exchange of business documents such as purchase orders, invoices, shipping notices, and more with trading partners. These can be suppliers, customers, carriers, third-party logistics providers (3PLs), or other supply chain connections. EDI solutions allow data to be transferred securely across computer systems, removing the need for manual entry and paper-based processes. EDI solutions ensure data is accurately and consistently exchanged between business partners using defined formats and protocols such as AS2. This article will discuss how to choose the right AS2 solutions for your EDI needs.

What is AS2?

The AS2 protocol is largely used in business applications to securely exchange documents like Electronic Data Interchange (EDI) documents or other data, such as XML, CSV, or plain text documents between multiple trading partners.

Benefits of AS2

The AS2 protocol provides various advantages to enterprises that use electronic data interchange (EDI).

  • AS2 enables the secure and encrypted transmission of EDI data over the Internet. It uses industry-standard encryption methods such as SSL (Secure Sockets Layer) or its successor TLS (Transport Layer Security). This ensures significant organizational data is safe and secure from unauthorized access.
  • AS2 allows reliable and assured message delivery. It uses acknowledgment methods to confirm effective message delivery and receipt between trading partners. This prevents communications from being lost or corrupted during transmission.
  • AS2 allows trading partners to share data in real-time. It eliminates the need for manual data entry and paper-based operations, leading to enhanced efficiency and fewer errors.
  • AS2 significantly minimizes communication costs associated with standard EDI solutions by leveraging the Internet and eliminating the need for specialized networks or VANs (Value Added Networks). It eliminates the per-transaction fees that are frequently associated with VAN services, resulting in cost reductions for EDI enterprises.
  • AS2 is a scalable solution capable of handling high transaction volumes. It can support businesses’ growing requirements as they expand their trading partner network and transaction volumes. AS2 also allows for integrating many systems and formats, such as EDI, XML, and other data formats typically used in business transactions.

Choosing the right AS2 solution, depending on the industry in which your company operates and whether your operations can effectively support it. There are several factors to be considered, including:

  1. Business Requirements - Examine your organization’s specific business needs and EDI requirements. Consider the types of documents you exchange with trading partners, the volume of transactions, the complexity of your supply chain, and any industry-specific standards or requirements that must be met.
  2. Compatibility and Interoperability - Determine that the AS2 solution you select is compatible with the systems of your trading partners. Check to see if it supports the AS2 protocol, as well as any other protocols or standards required for your specific EDI transactions. Interoperability is essential for ensuring efficient communication and data exchange.
  3. Scalability and Performance - Consider the AS2 solution’s scalability to accommodate your present and future transaction volumes. In terms of processing speed and dependability, assess its performance characteristics. Determine whether the solution is capable of handling large loads and whether it offers asynchronous or synchronous communication based on your requirements.
  4. Security and Encryption - Evaluate the security aspects of the AS2 solution. To protect data during transmission, look for support for secure encryption algorithms at AS2 level and SSL/ TLS with industry-grade algorithms at transmission level. Consider digital signatures and message integrity verification to confirm the authenticity and integrity of documents exchanged.
  5. Ease of Use and Configuration - Assess the AS2 solution’s usability. Consider how simple it is to configure, manage and monitor AS2 connections. Look for features like simple user interfaces, extensive logging and reporting, and automatic handling of errors and notifications.
  6. Cost and ROI - Consider the cost of the AS2 system, including license, deployment, and ongoing maintenance and support costs. Compare the entire cost of ownership against the possible return on investment in terms of efficiency gains, decreased error rates, improved partner relationships, and cost savings via optimized EDI processes.

How to choose right AS2 Software

You can select an AS2 solution that satisfies your specific EDI needs, improves security and dependability, and connects effectively with your existing systems and trading partner chain by carefully evaluating these aspects.


The AS2 protocol provides a secure, dependable, and standardized method for EDI connections, with advantages such as improved security, data integrity, automation, scalability, and cost savings. AS2 is a popular choice for enterprises interested in electronic data interchange because of these benefits. In conclusion, by carefully assessing your organization’s specific requirements, and considering key factors such as scalability, security, ease of integration, capability, and cost, you can select the perfect AS2 solution to meet your EDI needs.
