What ROTOR Software does

ROTOR Software GmbH, headquartered in Sankt Ingbert, Germany with a second office in Oyten, is a vertical dealer management and ERP software provider serving machinery dealers across the DACH market. The company was formed in 2021 through the merger of SEWIGA Software-Team GmbH and Orbis Software GmbH, consolidating 30+ years of combined experience and over 1,200 customers in the Motoristen (power equipment), Landtechnik (agricultural machinery), and Baumaschinen (construction machinery) segments. Its portfolio comprises two core Windows-based dealer management platforms — ORSwin and WinMLB — delivering modular functionality for machine sales, spare parts, workshop/service management, rental operations, POS, financial accounting, and warehouse management. A mobile companion app, ROTOR connect, extends these systems to iOS and Android for location-independent access.

The business model combines recurring software subscription and maintenance fees for ORSwin and WinMLB with professional IT services (infrastructure, server, data security) and a self-service e-commerce storefront selling barcode scanners, mobile data capture devices, label printers, and consumables. Go-to-market is direct and sales-led, with named account managers organized by product line, supported by live product demonstrations, an interactive product quiz for lead qualification, and a multi-channel content and event marketing program. The customer base is predominantly mid-market and SMB machinery dealers across seven vertical segments including agricultural, construction, commercial vehicle, municipal, cleaning equipment/Kärcher centers, and forklift dealers. As of June 16, 2026, ROTOR operates as a wholly-owned subsidiary of Aptean Inc., a US-based global vertical ERP provider, following an acquisition that expanded Aptean's equipment dealer footprint and DACH regional presence.
