What RZ Computersysteme does

RZ Computersysteme GmbH is an owner-managed (inhabergeführtes) German IT-Systemhaus founded in 1985 and headquartered in Sonthofen, Bavaria, with a second office in Mindelheim. It serves small and medium businesses and professional services firms across the southern Oberallgäu region — primarily tax advisory, auditing, and law firms, plus medical practices, hotels, social institutions, craft businesses, and small-to-medium industrial enterprises — with a relationship-driven, on-site-plus-remote service model anchored in a dedicated Betreuer-Prinzip (advisor-technician pairing per customer).

The core product portfolio is built around a DATEV Solution Partner 'first-hour' affiliation and bundles hosted and managed IT: DATEV accounting/payroll software with Finmatics document automation; Hosted Exchange email; Acronis-powered Online-Backup with monthly restore tests; Mailstore-based Mailarchivierung integrated with Microsoft Outlook; a tiered Mandanten-/Kundenportal for secure client/mandate file exchange (Basis €15.90, Comfort €29.90, Premium €59.90 monthly); Nuance Dragon + dns.comfort speech recognition with medical vocabularies; and RZSAFE, a Sophos UTM-based bundled managed-security appliance. The operational layer runs on AnyDesk remote maintenance, with on-site IT services, managed-service contracts, vacation coverage, and external DPO (Datenschutzbeauftragter) services.

The business model is a hybrid of recurring managed-services and subscription SaaS revenue streams, plus project-based IT services and DATEV software resale. There are no e-commerce or self-serve channels; all acquisition is direct and consultative. RZ Computersysteme is also a member of the serviceconnect Gruppe — a knowledge community (not a purchasing consortium) of 16 independent German system houses with 350+ employees — which extends Bundesweit service reach for multi-location customers while preserving local primacy. Ownership is founder/management-controlled, private GmbH, with no disclosed venture capital, PE, or institutional investment.
