The Challenge
Cummins Pacific manages complex industrial projects that require coordinating quotes, change orders, resource allocation, materials purchasing, and ongoing customer support. Their existing tools couldn't handle the interconnected nature of these workflows — quoting lived in one system, scheduling in another, and supply chain tracking was mostly manual. They needed a single platform that could manage projects from initial quote through completion and ongoing maintenance, with full visibility into resources, costs, and timelines.
Our Solution
We designed and built a custom Enterprise Resource Planning (ERP) system tailored to Cummins Pacific's specific workflows. Built on Oracle 11 and PHP 5.5, the web-based platform runs on Linux/Apache and is accessible from any device. The quoting module lets the team create, verify, and clone quotes efficiently — quotes can be sent to end-customers much faster than before. Change order management tracks granular changes to quotes with workflow approval, showing status and reasoning for each modification. The resource scheduling system shows allocations per worker, per task, and manages multi-project scheduling across a limited pool of workers on a single screen. Materials and supply chain tracking monitors purchasing and notifies admins when new materials need to be ordered. Sales synchronization tools measure ratios, forecast revenue, and help close deals. The entire system integrates with their legacy ERP for purchasing, scheduling, and maintenance continuity.

Frequently Asked Questions
Why build a custom ERP instead of using an off-the-shelf solution?
Off-the-shelf ERPs force you to adapt your workflows to the software. Cummins Pacific's operations — combining quoting, change orders, multi-project resource scheduling, and supply chain tracking — didn't fit neatly into any existing platform. A custom ERP was built around how they actually work, not the other way around.
How does resource scheduling work across multiple simultaneous projects?
The scheduling module shows a single-screen view of all worker allocations across all active projects. Managers can see who's assigned where, identify conflicts, and reallocate resources in real-time. This prevents double-booking and ensures the limited pool of workers is used efficiently.
Can a custom ERP integrate with existing legacy systems?
Yes — and it usually has to. We integrated the new ERP with Cummins Pacific's existing legacy system to maintain continuity for purchasing, appointment scheduling, and ongoing maintenance. Data flows between both systems so nothing falls through the cracks during transition.
