SERgroup Holding International GmbH, doing business as SER Group and rebranded to Doxis in January 2026, is a German enterprise content management (ECM) software vendor headquartered in Bonn. Founded in 1984, the company began as a pioneer in electronic archiving and now sells the Doxis Intelligent Content Automation platform, which combines revision-secure archiving with machine learning, AI, and process automation. As an SAP Registered Partner in the ISV category, SER offers SAP-integrated solutions including Doxis P2P for SAP for purchase-to-pay automation and Doxis O2C for SAP for order-to-cash automation, both running directly inside SAP user interfaces. The Doxis platform also extends to document management, knowledge management, contract lifecycle management, and intelligent invoice processing. The company employs more than 600 people across approximately 20 offices in 11 countries. Ownership has changed in recent years: The Carlyle Group acquired a majority stake in January 2019, and in March 2024 TA Associates became the new lead investor with Carlyle remaining as a significant minority investor. The January 2026 rebrand to Doxis aligns the company name with its core product platform under an AI-first positioning.
