SGP Schneider Geiwitz Neckaralb GmbH

What SGP Schneider Geiwitz Neckaralb GmbH does

SGP Schneider Geiwitz Neckaralb GmbH is a regional German tax advisory and accounting firm headquartered in Reutlingen, Baden-Württemberg, operating three offices across the Neckar-Alb region (Reutlingen HQ, Neuffen, Gammertingen) with approximately 50+ staff sourced from local disclosures. The firm was originally founded as NAT AG in 2009, expanded into Gammertingen in 2010 and Neuffen in 2020 via the acquisition of Dr. Prinz + Partner, then merged into the SGP Schneider Geiwitz network effective 1 January 2025, at which point it was formally recognized by the Steuerberaterkammer Stuttgart as a Steuerberatungsgesellschaft and rebranded to its current name.

The core service catalog spans Steuerberatung (tax advisory including Gestaltungsberatung), Finanzbuchhaltung, Lohnbuchhaltung, Jahresabschluss, and tax return preparation for both private individuals and businesses, augmented by specialized practices in Existenzgründung (business start-up consulting), Umstrukturierungsberatung (restructuring), Nachfolgeberatung (succession planning), Internationales Steuerrecht (with a niche in Swiss Grenzgänger cross-border commuters), Steuerstrafrecht, and Finanzgerichtliche Verfahren. The 2025 SGP partnership added Wirtschaftsprüfung (auditing) and Rechtsberatung (legal advisory) to the offering. The underlying technology stack is DATEV-centric: DATEV Unternehmen online for client-firm digital document exchange, digital personnel files, and remote IT support resolving approximately 90% of cases via Fernwartung, with custom Schnittstellen programming to integrate heterogeneous client ERP systems.

The commercial model is professional-services hourly/engagement fees governed by the Steuerberatervergütungsverordnung (StBVV), sold through a sales-led, relationship-driven motion anchored on local presence, fixed personal advisors per client, and referral-based acquisition. Pricing is not publicly disclosed; multi-year client relationships and recurring compliance work underpin revenue. The firm serves primarily SMBs, self-employed professionals, private individuals, and a specialist Swiss cross-border commuter segment, all within a tightly defined regional geography of Neckar-Alb.
