The Challenge
Mattr (Shawflex), a leader in providing a wide range of specialized parts to its customers, relied on a legacy VBA-based configurator for generating quotes and calculating prices. This legacy system had become outdated, difficult to maintain, and limited in scalability.
The configurator was critical for both the engineering and sales teams to compute complex pricing logic and part-specific calculations. However, the old system lacked flexibility, modern UI capabilities, and integration potential with other tools. Additionally, Mattr required a reliable method to validate results between the old and new systems during the transition phase, ensuring calculation accuracy and maintaining operational confidence.
Our Approach
We replaced Mattr’s legacy VBA configurator with a modern, scalable React-based configurator designed for flexibility, maintainability, and improved user experience. Our process included extensive collaboration with both the engineering and sales teams to refine requirements and introduce new capabilities.
Modern Configurator Development
Migrated all legacy VBA logic into a modular React framework with a modern UI. Designed an extendable architecture with improved logic for quotes, pricing, and part-specific calculations.
Harness Module for Verification
Developed a harness verification tool to compare outputs from the legacy and new systems. Enabled automated checks for calculation discrepancies, ensuring a smooth rollout.
Collaborative Enhancement Sessions
Conducted multiple workshops with engineering and sales teams to gather feedback. Implemented requested optimizations to improve usability and accuracy.
Improved System Performance & Usability
Enhanced UI/UX for faster input and computation. Reduced manual work by streamlining complex calculation workflows.



The Outcome
The new configurator transformed Mattr’s quoting and pricing process into a faster, more accurate, and future-ready system. The improved platform not only increased efficiency but also boosted team confidence in results during and after migration.
100% Calculation Accuracy Validation
Harness module ensured perfect alignment with legacy system outputs before the full rollout.
Significantly Faster Quoting Process
Reduced time to prepare quotes and pricing, enabling quicker turnaround for customers.
Future-Proof Architecture
Modular React framework allows seamless scaling and integration of new features.
Reduced Maintenance Overhead
Eliminated the complexity of maintaining outdated VBA code.
