Welcome To ZeroOneTech
The Challenge
RatioData, a German IT services company, faced several key challenges in managing its B2B sales ecosystem:
Diverse B2B Customer Groups
Three distinct customer types, each requiring different authentication flows and pricing rules:
Insurance broker portal users (VB Ruvis)
General agencies (Generalagentur)
Commercial and wholesale customers (Handel / Großhandel)
Dynamic External Pricing
Real-time price retrieval from external suppliers (ITSCOPE) with RatioData’s profit margins applied dynamically.
Large-Scale Product Synchronization
Daily import of over 50,000 products (≈ 1 GB JSON file) without memory overload or timeout failures.
Enterprise System Integration
Automatic order export to RatioData’s ESB system, triggering ITSM tickets and internal workflows.
Credit Risk Management
Automated credit-rating verification for B2B customers before final order approval.
ZeroOneTech developed a custom Shopware 6.6.3.0 B2B platform, built around modular, high-performance plugins designed specifically for RatioData’s workflows.
