Client Background and Business Context
Wolseley Group is the UK’s largest specialist trade merchant for plumbing, heating, cooling, and utility products. Operating approximately 650 locations across the UK and Ireland and supported by extensive distribution and fulfilment capabilities, Wolseley serves a diverse customer base ranging from independent tradespeople to major construction organizations.
For many years, Wolseley’s operations relied on deeply embedded legacy green-screen technologies and fragmented business processes. While these systems had supported the organization for decades, they increasingly limited the company’s ability to scale, standardize operations, and gain real-time visibility across its network.
The order fulfilment lifecycle involved multiple systems and processes spanning order capture, inventory validation, procurement, planning, and delivery. Managing customer-specific pricing, credit validation, inventory availability, and multi-supplier sourcing added significant operational complexity. The organization seeks to eliminate disconnected legacy applications, reduce manual intervention, improve process consistency, and establish a modern digital foundation capable of supporting future growth and acquisitions. Additionally, Wolseley requires seamless integration with its existing Distribution Center (DC) ecosystem while minimizing disruption to ongoing branch operations.
Trinamix is delivering a comprehensive Oracle Fusion Cloud SCM transformation designed to modernize Wolseley’s end-to-end supply chain operations. The transformation is expected to unify critical business processes, improve integration across planning and execution functions, enable greater automation, and establish a flexible digital foundation to support business growth, operational efficiency, and evolving technology requirements.

LONG-TERM PARTNERSHIP
The partnership between Wolseley and Trinamix began with a focused engagement centred on demand planning optimization and planning enhancements. By delivering measurable value and demonstrating a deep understanding of Wolseley’s business requirements, Trinamix steadily expanded its role within the organization. What started as a targeted planning initiative evolved into a broader transformation journey built on trust, collaboration, and consistent delivery.
Â
Over approximately five years, Trinamix supported Wolseley through multiple stages of transformation, including planning optimization, proof-of-concept validation, architecture design, functional assessment, and Oracle Fusion capability evaluation. Through this phased and methodical approach, Trinamix became Wolseley’s strategic Oracle Fusion SCM implementation partner for one of the company’s most significant modernization programs. Rather than following a traditional client-vendor model, both organizations worked as a unified delivery team, combining Wolseley’s deep industry expertise with Trinamix’s Oracle Cloud engineering and supply chain transformation capabilities. Together, they established a scalable architecture capable of supporting complex operations, large transaction volumes, and uninterrupted branch activities throughout the transformation journey.
“Modernizing a supply chain environment of this scale required more than replacing legacy systems—it required creating a connected platform across planning, procurement, inventory, and fulfilment,” says Roger Connett, CTO & Managing Director, Specialist Business Division, Wolseley Group. “Working closely with Trinamix, we are establishing a unified Oracle Fusion Cloud SCM foundation that improves visibility, streamlines operations, and positions us to support future business growth.”
“Every successful transformation begins with understanding the customer’s business and building the right foundation for change,” says Bobby Shome, VP of Sales (Europe), Trinamix. “Our partnership with Wolseley reflects that approach, combining Oracle Fusion Cloud SCM with deep supply chain expertise to create an integrated platform that supports operational efficiency, scalability, and future innovation.”
Key Solution Highlights
 Unified Supply Chain Platform: Oracle Fusion SCM will replace fragmented legacy applications and establish a unified operating platform that supports end-to-end supply chain execution, planning, procurement, and fulfilment activities.
 Real-Time Order Orchestration: Oracle Fusion SCM will enable real-time order orchestration with embedded stock availability checks and credit validation directly within the order capture process, helping improve accuracy and reduce downstream fulfilment issues.
 End-to-End Process Integration: Integration across Order Management, Procurement, Planning, Inventory, and Fulfilment will create a seamless workflow that improves coordination, visibility, and operational efficiency across the enterprise.
 Modern User Experience: Trinamix will support the development of Oracle Cloud UI extensions and modern Redwood-based user experiences tailored to branch operations. These enhancements will address usability challenges, improve productivity, and accelerate user adoption.
 Enterprise Architecture and Functional Fitment: Trinamix will design and validate the end-to-end Oracle Fusion architecture across Planning and SCM functions while evaluating standard functionality, extension requirements, and process fitment across supply chain modules. This approach is helping ensure scalability while minimizing unnecessary customization.
 Distribution Centre Integration: Seamless integration with Wolseley’s existing Distribution Centre (DC) environment will support business continuity and enable a smooth transition from legacy technologies to cloud-based operations.
 Foundation for AI-Driven Innovation: A scalable data foundation will be established to support future AI-driven capabilities. Wolseley is also evaluating both Oracle AI Agents and custom AI agents to enable intelligent automation, predictive decision-making, and process orchestration, with a focus on addressing specific business challenges and delivering measurable value.
