Case Studies/ERP & Modernization

Accounts & Inventory
System Modernization

A mid-size trading company had outgrown its aging desktop accounting system. ABS performed a legacy assessment, extracted core business logic, and rebuilt the platform as a modern web-based ERP.

The Challenge

The trading company had been using a VB6-based desktop accounting system for over a decade. It was single-user, couldn't be accessed remotely, and required manual data exports for any kind of reporting.

  • Single-user desktop system — only one person could access accounts at a time
  • No multi-branch support — branch operations tracked in separate spreadsheets
  • No real-time inventory visibility — stock counts done manually and infrequently
  • Year-end financial reporting required days of manual data consolidation
  • System was no longer supported — risk of data loss and compliance exposure

The ABS Approach

ABS started with a legacy system audit — documenting all business processes, data structures, and critical logic embedded in the VB6 application. This included extracting and validating historical data from the legacy database.

The rebuild was designed as a phased delivery: core accounts first, then inventory, then reporting dashboards. This minimized disruption to operations while ensuring business continuity throughout the transition.
