Customer portal and B2B catalog development
We build portals and catalogs that connect to your ERP and stay fast even with millions of items.
Where clients usually start
- Product data is maintained in three places and none of them is fully correct.
- Search only finds an item if you know the exact part number.
- The shop is a standard system that has had every special rule bolted on over the years. Every update is a risk.
What we do
Customer portals
Sign-in, orders, documents and order status in one place. The data comes from your ERP, so nobody maintains it twice.
B2B catalogs
Large assortments with customer-specific prices and contracts. Search finds items by name, manufacturer or part number.
Online stores
Shopware, Magento or a custom build. We choose based on how much custom logic your business needs.
ERP and PIM integration
Items, prices, inventory and orders flow through interfaces. If one fails, we get an alert before your customers notice.
Operations
After launch we keep running the platform: monitoring, updates and ongoing development by the same team that built it.

From a real project
LANXESS: a catalog with more than 5 million items
We built a procurement catalog system for LANXESS. Its search knows the company's SAP contracts and part numbers. It went live worldwide in 2015. After a switch to SAP Ariba, LANXESS came back in 2025, and since August 2026 the system has been running worldwide again.
