Revenue model

1. Software Licensing & Subscriptions (KOSS Modules): KOSS offers its ERP platform and modules (KOSS.ERP, KOSS.FIBU, KOSS.PZE, KOSS.AKTEN, KOSS.B2B, KOSS.BI) as proprietary business software to small and mid-sized enterprises (KMU) in Germany. Modules can be purchased individually or as an integrated All-in-One solution. Revenue is generated through software licenses, likely with annual maintenance/support fees.
2. Individual Software Development & Customization: GCI/KOSS develops individualized business software tailored to specific customer requirements. The consulting and development process follows a structured three-step approach: needs analysis, concept development, and custom programming. This represents a professional services revenue stream.
3. IT Infrastructure & Hardware Sales: GCI provides comprehensive IT infrastructure services including server setup, antivirus software, and hardware procurement alongside their software. The company also resells Datafox time-tracking terminals bundled with KOSS.PZE. Hardware sales and IT administration services generate additional revenue.

Core offering

KOSS develops and sells a proprietary, modular All-in-One ERP software suite (KOSS.ERP) for small and medium-sized enterprises (KMU) in Germany. The suite covers sales, purchasing, warehousing, logistics, production planning, financial accounting, time tracking, document management, B2B e-commerce, and business intelligence through six integrated modules (KOSS.ERP, KOSS.FIBU, KOSS.PZE, KOSS.AKTEN, KOSS.B2B, KOSS.BI) plus the KOSS zAPP mobile companion app. Modules can be deployed individually or as an integrated solution, available on-premise or in the cloud, with customization, implementation consulting, and ongoing support delivered in-house from Dortmund.

Product overview

KOSS is a modular All-in-One business software suite built by GCI mbH (Dortmund, Germany) for small and medium-sized enterprises. The portfolio centers on KOSS.ERP as the core platform, supplemented by five integrated modules: KOSS.FIBU (financial accounting), KOSS.PZE (time and attendance), KOSS.AKTEN (document management, integrated with windream DMS), KOSS.B2B (B2B eCommerce and sales portal), and KOSS.BI (business intelligence with interactive dashboards). The modular architecture allows companies to deploy modules individually or as a fully integrated All-in-One solution. A mobile app (KOSS zAPP) extends time recording to smartphones. Individual customized platforms (e.g., KOSS.Cloer) are also built on the KOSS framework. The WebKOSS layer adds web-based access with SSO. GCI additionally provides comprehensive consulting, implementation, and ongoing support services under the KOSS.Service brand.
