Wyzwanie biznesowe
The client approached us with critical challenges that threatened their competitiveness in the rapidly evolving online fashion market:
Legacy Platform Limitations
The existing Shopware 5 infrastructure was reaching end-of-life, creating significant operational risks. The platform’s outdated architecture couldn’t handle the complex product variations typical in lighting industry – different sizes, colors, materials, and lengths. Managing over 5,000 SKUs with multiple variants became increasingly cumbersome and error-prone.
Performance and User Experience Issues
Mobile performance was particularly concerning, with page load times averaging 11 seconds on smartphones – critical in an industry where visual appeal and quick browsing are essential. Desktop performance wasn’t optimal either, with average load times of 6.2 seconds. These delays directly impacted the shopping experience, especially for fashion customers who typically browse multiple products before making decisions.
The conversion rate had stagnated at 1.3%, significantly below the industry average of 2.8%. Cart abandonment rates reached 73%, with mobile users particularly affected by the poor performance.
Inventory Management Complexity
The client’s warehouse operations relied on JTL-WMS (Warehouse Management System), but the integration with their existing Shopware 5 store was limited and often required manual intervention. This created synchronization issues between inventory levels, product information, and order processing, leading to overselling incidents and customer dissatisfaction.
SEO and Marketing Limitations
The legacy platform’s SEO capabilities were insufficient for competing in the highly competitive market. Core Web Vitals scores were poor, affecting Google rankings. The platform’s limited marketing automation features meant missed opportunities for personalized campaigns crucial in fashion retail.
Project Scope – Migration from Shopware 5 to Shopware 6 with JTL Integration
We were tasked with executing a comprehensive platform migration that would address all technical limitations while maintaining business continuity. The project’s complexity was heightened by the need to integrate JTL Connector for seamless warehouse management integration.
The scope included complete data migration, custom module development for lighting-specific requirements, JTL Connector implementation, and ensuring zero downtime during the transition period.

Advanced Caching Implementation

This reduced mobile page load times from 11 seconds to 4.2 seconds and desktop performance from 6.2 seconds to 2.8 seconds.

We developed custom modules to handle complex fashion product structures, including size matrices, color variations, lengths, and stock management across multiple warehouses.
