An insulating and architectural glass manufacturer needed one system for thousands of valid product combinations. Over a fourteen-year relationship, Costel took the platform from a single-computer desktop tool to a factory-wide web application, dealer self-service and a modern rebuild that connects quotation directly to ERP and machinery.
Architectural glass pricing depends on far more than width and height: glass types, treatments, grinding, drilling, cut-outs, structural parts, accessories, dimensional limits and customer-specific prices all interact.
Some choices make later options mandatory; others make them impossible. Before those rules lived in software, every quote depended on specialist knowledge and every manual selection created another chance for error.
The first Visual Basic application centralized insulating-glass orders on one computer. Three years later, a PHP and MySQL web platform made the same information available across production, administration, sales and management.
When the company expanded into architectural glass, Costel added a rule-driven configurator. A user enters dimensions, and the platform filters compatible materials, operations and accessories while applying processing costs, discounts and negotiated prices.
Product rules, quotation management and production restrictions live in the same platform.
The configured product is the source of truth. If quotation, ERP and CNC each rebuild the same rules independently, they eventually disagree. Keeping one validated configuration through every step ensures that what is priced is exactly what reaches production.
Roughly twenty internal users and more than thirty dealers now work from the same validated product rules.
A calculation that once took tens of minutes or hours is generated in minutes or seconds. Dealers can quote independently, produce branded PDFs and turn accepted offers into orders without the factory re-entering the product.
After eleven years in production, the original web application was rebuilt in 2026 with Laravel and Vue.js. The continuity is the result: each generation stayed useful because it evolved with the products, machinery and teams around it.
A keyboard-first platform replaced paper and made 500 to 1,000 custom orders a day workable.
A product-specific checklist made vehicle loading verifiable and stayed useful for seven years.
