Case Study: Department Store Retailer achieves mobile AS/400 connectivity with OpenLegacy

A leading department store buys into mobile AS/400 connectivity - without the hefty price tag

The Department Store Retailer, the largest department store chain in its country, relied on IBM AS/400 systems for store management, sales tracking, reporting, and finance, but struggled with outdated “green screen” interfaces, limited mobile access, and difficulty sharing data with other applications. An ERP migration was considered, but the cost and 3–5 year timeline made it impractical, so the retailer needed a faster, lower-cost way to unlock legacy data.

Using the OpenLegacy platform and its OpenMobile module, OpenLegacy helped the retailer build a mobile app on top of its AS/400 sales application in just 2.5 days. The solution delivered real-time sales visibility on smartphones and tablets, added easy-to-read charts and year-over-year comparisons, and improved manager productivity while avoiding changes to the legacy environment and preserving AS/400 reliability, security, and data accuracy.
