The Challenge
Managing large-scale device procurement for corporate clients like AOK and ITSCare requires more than a simple online shop. The client needed a centralized B2B platform where thousands of users could browse, request, and approve purchases across multiple organizations — all while syncing automatically with T-Systems APIs and maintaining strict workflow and access control rules.
The challenge was to build a flexible, enterprise-grade e-commerce system capable of:
Handling complex organizational hierarchies
Integrating real-time product and pricing updates from an external system (TSI)
Supporting multi-shop environments under a unified platform
Enforcing multi-level approval processes based on budgets, cost centers, and user permissions
ZeroOneTech designed and implemented a custom B2B e-commerce platform built on Shopware 5.
The solution allows corporate customers to manage their full device lifecycle — from ordering and approval to asset tracking and disposal — all within one integrated system.
