AS400 ERP, belonging to IBM, is commonly referred to as a mid-range server. Originating in 1988, AS400 iSeries serves as foundational software that has gained popularity among businesses, being utilized by approximately one hundred thousand organizations across various industries.

Despite perceptions of its effectiveness, AS400 ERP remains a reliable solution, meeting the diverse requirements of businesses. Terms such as IBMi, iSeries, or System i are interchangeably used and are part of branding campaigns associated with IBM.

The IBMi system offers a broad range of functions, providing a combination of interactive AS400 database services and internet capabilities. Additionally, it encompasses storage management, security features, and networking capabilities. AS400 Accounting Software is renowned for its role in operating e-commerce hosting, web development, Java application development, and data warehousing.


Contrary to common misconceptions, IBM AS400 is not categorized as ERP, despite novice users occasionally referring to it as AS400 Enterprise Resource Planning Software. Instead, AS400 functions as an operating system, comparable to Microsoft Windows or Linux. The distinguishing factor lies in the object-oriented nature of AS400

where everything is defined as an object, unlike other operating systems that conceptualize hardware and software items as files. The IBM AS400 or IBM iSeries platform integrates IBM DB/400 databases, hardware, programming and software development environments, and the OS/400 operating system. Numerous mission-critical business applications, including ERP systems, run on this platform, offering stability, reliability, high performance, and security.

What are the Challenges of AS400 Accounting Software?

Despite its robust technology, the i5 system, which AS400 is part of, faces challenges. Some users mistakenly perceive AS400 Software as obsolete, not recognizing its compatibility excellence. This misconception can lead to missed opportunities for companies seeking a stable and reliable solution.

Another challenge is the aging workforce associated with AS400. As individuals with in-depth knowledge of IBMi retire, there's a risk of losing valuable expertise. Although the system may appear dated, it possesses a complex internal architecture, emphasizing the need for training and knowledge transfer to newer staff members.
