Client Context
The client is a German multi-channel retailer serving both B2B and B2C customers across multiple online platforms. Self-described as pragmatic, solution-oriented, and technology-driven, the company has built a strong position in German e-commerce through its focus on functional, performance-oriented product lines. By 2023, the business had grown to a balance sheet of €6 million, which was up 25.4% year-over-year, reflecting consistent commercial momentum. Operations span two sales channels with distinct requirements, underpinned by a single technology layer that had historically been pushed well beyond its original design.
The Challenge
The client’s existing platform was an OXID-based system that had served the business for years. But growth changed its character. As the product catalog expanded and traffic surged, what had been a stable foundation became a source of friction. The first problem was performance. With more SKUs and more concurrent users, even modest page-load delays began showing up as conversion loss. In e-commerce, a second of hesitation is often a permanent departure. The system wasn’t failing outright, but it was quietly losing customers at the edges. The second problem was architectural. Plugin development had been duplicated separately across platforms, meaning any new feature required building the same logic multiple times. This multiplied engineering overhead, slowed release cycles, and made the codebase progressively harder to maintain. Personalization was difficult to implement, and marketing integrations were limited. The storefront itself, once considered current, no longer reflected the experience the company wanted to offer. The third problem was strategic. With B2B and B2C operations running on the same aging infrastructure, the enterprise was constrained in its ability to optimize each channel independently or respond to evolving customer expectations at speed. The accumulated technical debt had made every change slower and riskier than it needed to be.
The Approach
Gradion engaged with a clear scope: migrate the client from OXID to Shopware 6, and use the migration as an opportunity to redesign the architecture, not just replicate what existed. The first decision was to introduce a unified plugin architecture, which was a single framework under which features could be built once and applied across all platforms. This directly addressed the duplication problem and shifted the development model from repeated parallel effort to reusable, maintained components. In parallel, the storefront was completely redesigned. The goal was a modern, intuitive interface that worked equally well for B2B procurement workflows and B2C consumer browsing, without compromising either. Visual consistency, navigation clarity, and mobile usability were treated as first-class requirements, not afterthoughts. Behind the interface, Gradion optimized the platform to handle large catalogs and high concurrent traffic without degradation. Shopware 6’s flexible architecture provided the foundation, but the tuning required for the company’s specific catalog depth and traffic patterns was custom work. The engagement was structured to minimize disruption to live operations throughout the transition. Communication between Gradion and the client's team remained direct and practical throughout, with shared goals driving decisions rather than process overhead.

reduction in redundant development work through the unified plugin architecture
The Results
The shift to Shopware delivered measurable improvement at every level: 70% reduction in redundant development work: Through the unified plugin architecture, engineering time was reallocated from maintenance to new capability. Full storefront redesign: Delivering a modern, conversion-oriented experience across both B2B and B2C touchpoints. Faster time-to-market: For new features and campaigns, with release cycles materially shortened. Advanced feature integration: Previously impossible on the OXID system, these are now achievable within standard sprint cadences. Stronger technical foundation: Prepared for continued catalog and traffic growth without further architectural constraint. The migration did not simply fix a slow system. It changed the client’s development economics, as less time spent maintaining legacy code means more time building capability. In a market where product discovery speed and storefront experience drive conversion, that shift is directly commercial.
