AS400 RPG Enhancement and Managed Services for a Leading Decorative Fabrics Distributor
Introduction
The client is one of the world’s largest distributors of decorative fabrics and furnishings, supplying both residential and commercial markets for more than half a century. Its custom‑built ERP, written in AS400 RPG, underpins order handling, inventory, memo‑order processing, and shipping. Rising customer expectations and a growing e‑commerce footprint made it clear the platform needed ongoing enhancements and a stronger support model to stay competitive.
The Challenge — Legacy Complexity Slowing Business Agility
Aging codebase
Tens of thousands of lines of RPG/CL with limited documentation hinder rapid change.
Escalating support tickets
Frequent break‑fix requests across critical workflows stretched the in‑house team.
Knowledge bottleneck
Core knowhow sat with a few senior employees, creating risk and limiting modernization bandwidth.
Visibility gaps
Workflow dependencies and performance bottlenecks were poorly mapped, making optimization difficult.
Need to refocus internal talent
Management wanted client engineers free to drive AS400 modernization while day‑to‑day care shifted to a partner.
