From Legacy ERP to Modern eCommerce: A Glass Supplier’s Journey

By Glazix | May 30, 2025

Transitioning from an on-premise ERP built for back-office accounting to a cloud-native eCommerce ecosystem unlocks agility, scalability, and superior customer experiences for glass distributors.

Many established glass suppliers began with legacy ERPs focused on financials and inventory at a high level. These systems excelled at ledger management and aggregate stock counts but lacked the flexibility needed for real-time order processing, digital storefronts, or integrated CRM workflows. As customer demands evolved—seeking online product configurators for tempered glass or instant quotes for insulated glazing units—legacy ERPs struggled to adapt without costly customizations.

The first step in the journey is conducting a holistic technology audit. Stakeholders from sales, operations, IT, and finance map current processes and pain points. For a mid-sized glass supplier, this revealed several issues: delayed order confirmations, manual quotation spreadsheets, and fractured customer data across siloed systems. Rather than ripping and replacing overnight, the company adopted a phased approach: introducing an eCommerce platform that integrates via APIs with the ERP, while gradually migrating critical modules to the cloud.

Phase one involved implementing a headless commerce solution tailored to B2B glass customers. The new storefront supports custom product configurations—allowing architects and contractors to specify dimensions, edge finishes, and safety features. API calls to the legacy ERP fetch real-time pricing tiers and tiered volume discounts. Orders placed online generate sales orders directly in the ERP, eliminating manual entry and reducing errors.

Simultaneously, the team rolled out a modern CRM to replace fragmented spreadsheets. Customer profiles, project histories, and communication logs are centralized. Integration with the commerce platform surfaces upsell opportunities—such as related hardware or installation services—directly in the CRM, empowering sales reps with context at every touchpoint.

Phase two focuses on migrating core ERP modules to a cloud ERP designed for distribution. The benefits include automatic software updates, elastic computing resources to handle seasonal peak traffic, and embedded analytics. Real-time dashboards provide executives with insights into order backlogs, inventory turnover by SKU, and customer lifetime value. The cloud ERP’s open architecture simplifies future integrations—such as connecting to freight marketplaces or IoT-enabled warehouse sensors.

Throughout the transformation, change management is critical. The supplier established a cross-functional steering committee to oversee training, data migration, and cut-over plans. Superusers from each department received hands-on workshops, and a parallel run period ensured the new systems processed live orders alongside the legacy ERP until confidence grew. Communication channels—weekly town halls and a dedicated intranet portal—kept the broader workforce engaged and informed.

Customer feedback guided iterative improvements. Early adopters praised the new online configurator but requested enhanced visual previews. The eCommerce team integrated a 3D rendering engine, enabling buyers to rotate and zoom glass panels in virtual mock-ups. This reduced quote-to-order cycle times by 30% and led to a 15% increase in average order value.

By year three, the supplier fully sunset its on-premise ERP, operating entirely on cloud platforms. Total cost of ownership declined by 20% due to reduced infrastructure and maintenance fees. Order processing times dropped from 48 hours to under two hours on average. Net promoter scores rose as customers enjoyed seamless self-service and faster delivery estimates.

The journey from legacy ERP to modern eCommerce is neither trivial nor risk-free, but for glass suppliers, it delivers clear competitive advantages. A phased integration strategy, stakeholder alignment, robust change management, and customer-centric enhancements pave the way. Modern platforms unlock real-time data, configurability, and scalability—transforming how glass distributors engage buyers, manage operations, and grow revenue in a digital-first market.
