Beyond the standard: Tailored B2B solutions for complex commerce

B2B e-commerce is rarely one-size-fits-all. That’s why we develop advanced, customized solutions that go far beyond standard functionalities – whether in Shopware, OXID eSales, mobile apps, or entirely bespoke platforms. From ERP-connected quick order tools to multi-buyer account systems, our extensions and applications are built to reflect the complexity of your business and the precision your customers expect. Explore how we turn B2B challenges into streamlined digital experiences.

#01

Shopware for B2B – Extensions that go further

As a certified Shopware agency, we develop functional enhancements specifically designed for B2B needs. One example: variant tables directly on product pages – perfect for quick ordering in wholesale. Other features, like customer-specific article numbers or custom delivery dates (taking company holidays into account), significantly improve usability for your B2B customers. We also develop smart ERP-linked order history views, CSV-based quick orders and representative logins with custom role management. These solutions streamline the buying process and build customer loyalty through transparency and ease of use.

OXID eSales – Modules for advanced business logic

In the OXID ecosystem, we create extensions that meet the demands of complex B2B structures. Whether it's multi-client setups for corporate groups, SAP® integration or self-managed customer accounts with multiple buyers – our modules are designed to reflect sophisticated distribution structures. We also develop custom features, such as order simulations that allow purchasing departments to calculate and coordinate internally before placing an order. Combined with powerful ERP and PIM interfaces, these tools enable scalable, flexible e-commerce platforms with seamless integration.

App development for B2B – Mobile and connected

B2B doesn’t stop at the browser. We build native and cross-platform apps that support sales teams, logistics, and trade partners in the field. Whether it’s internal ordering tools, trade show apps, or mobile order capture apps with ERP connectivity – we build solutions that are custom-fit to your business model and user needs. Through deep API integration, we enable real-time data exchange, wherever it’s needed.

Custom Software Development – When standard doesn’t cut It

When off-the-shelf tools fall short, we develop exactly what you need: custom business applications, middleware systems, data pipelines and interface solutions – all based on modern technology stacks. From requirements analysis to system architecture to agile delivery – we support your project end-to-end. Our expertise spans server-side API development, ERP-focused extensions and data-heavy applications for supply chains, portals and customer platforms.
