Unified Commerce: Transforming the Integration of E-commerce Platforms and SAP Systems

February 2024

S5 Consulting has engineered a pioneering integration solution, seamlessly merging Webshop front-end, Order Management System with SAP back-end systems.

For ARK, this transformation equates to a significant boost in profitability and online sales.

We've observed a substantial reduction in system errors, resulting in a more reliable and easily monitored environment, resilient against server downtimes.

The need

The previous Webshop solution was based on outdated technology, making it complex to monitor and develop new features. Moreover, if the SAP backend was down, the entire Webshop would become non-functional.

Our solution

The S5 Consulting team has innovated a cloud-based, event-driven, API-first middleware solution, integrating on-premise SAP systems (CRM and ECC) with cutting-edge third-party platforms (Bluestone PIM, CommerceTools, Omnium). Utilizing the SAP BTP Integration Suite, the solution comprises key components such as Cloud Integration, API Management, and EventMesh. The event-driven architecture, implemented in EventMesh, ensures continuous operation, independent of server downtime.



  • Increased online sales through the new Webshop
  • Enhanced user experience for both external customers ordering books and internal employees interacting with the systems
  • A robust system architecture ensuring continuous operation regardless of server status
