IntarS

What IntarS does

IntarS Unternehmenssoftware GmbH is a privately held German software company headquartered in Coburg that has operated continuously since 1999 (incorporated in 2000 as seat-1 Software GmbH, renamed in 2015). The company develops and distributes IntarS ERP, a web-based, open-source (GPL) enterprise resource planning, production planning, and inventory management system aimed at small to medium-sized trading, manufacturing, and service firms in the German Mittelstand. The technology stack runs on Linux (Debian) with a MariaDB database, is accessed via browser (Firefox/Chrome) without client installation, and is cloud-capable with deployment on Amazon Web Services. The product is modular — covering Faktura, Buchhaltung, Lagerverwaltung, Fertigung, Einkauf, CRM, DMS, Projektmanagement, Personalzeiterfassung, Bruttolohnabrechnung, Mobile Datenerfassung (MDE), and a B2B Shop — and supports industry-specific configurations for sectors such as furniture, bicycles, metal, publishing, automotive suppliers, and electronics.

The company's revenue model is mixed: a free IntarS Lite tier (Freemium) for very small businesses, a one-time/perpetual IntarS PRO license for SMEs without industry-specific functionality, and IntarS ERP sold as an annual subscription with bundled SaaS hosting options. Layered on top are paid professional services (implementation, migration, training) and recurring support contracts. Distribution combines a self-serve download (Virtual Appliance and AWS marketplace), direct enterprise implementation by IntarS, and a certified partner channel (Application Design & Development in Vienna and Lignos Project in Dresden) that provides regional implementation coverage.

Approximately 100 companies use the product across diverse industries, with recent customer wins in electrical, sensor technology, plant engineering, bicycles (GHOST, Benno Bikes), furniture (Finori, Pemora, objekt-m), textiles (FEILER), and a nonprofit (Bremer Tafel). Recent strategic activity centers on a product-modernization push in 2024–2026: AI-powered document recognition and translations (both built on third-party LLMs), Polish e-invoice (KSeF) compliance, REST API modules, a supplier portal, a calendar module, integrated chat, and direct in-browser document editing. The company remains founder-controlled — Ralf Engelhardt is sole managing director since co-founder Pirmin Braun's departure in mid-2018 — with no disclosed external funding.
