Schüllermann

What Schüllermann does

Schüllermann und Partner AG is a German professional services firm headquartered in Dreieich, operating as a multi-entity group under private ownership (AG legal form, not publicly listed) with four wholly-owned subsidiaries: SCS Schüllermann Consulting GmbH (management consulting), SRS Schüllermann und Partner mbB (legal, audit, tax), Schüllermann Wirtschafts- und Steuerberatung GmbH (tax), and Schüllermann Dataservice GmbH (IT/data services including whistleblower portal). Founded in 1969 with 51–100 employees, the firm operates across 12 German office locations (Berlin, Köln, München, Mannheim, Mainz, Würzburg, Leipzig, Kassel, Hannover, Erfurt, Sigmaringen, and Dreieich HQ).

The firm's revenue model is professional-services fee-for-engagement, with pricing delivered via custom quotes rather than public rate cards. Six primary service streams generate revenue: Wirtschaftsprüfung (auditing — annual and consolidated financial statements, due diligence, special audits); Steuerberatung (tax advisory — corporate, income, inheritance, international tax, restructuring, succession); Rechtsberatung (legal advisory — labor, data protection, commercial, public procurement, EU state aid, municipal, health, M&A, insolvency); Unternehmensberatung (management consulting — controlling, process/risk management, actuarial); Kommunalberatung (municipal advisory — Doppik accounting, budget protection, fee calculations, digital structures); and Digitalisierung (digital transformation for public administration, external data protection officers). Proprietary technology products include SWS.pro® (digital Tax Compliance Management System developed with CaseWare Germany, used by 240+ municipalities), Kasaia® (TVöD-VKA job evaluation database), and Cryptshare® (secure file transfer).

The go-to-market is sales-led, with direct consultant engagement supported by thought-leadership content marketing — regular newsletters (Mandanteninformationsbrief, Steuer Web-News, SRS-Updates), free info webinars on regulatory topics as lead generation, and corporate LinkedIn/Xing/Facebook presence. Customer segments are organized by vertical: Öffentlicher Bereich (public sector) and Gemeinnütziger Bereich (non-profits) as primary segments, with Gewerblicher Bereich (commercial), Privater Bereich (high-net-worth individuals), Kirchlicher Bereich (church sector), and Kunst und Kultur (arts/culture) as secondary verticals. The firm was recognized as one of the "Top Wirtschaftsprüfungskanzleien 2026" by Capital and Statista in the Jahresabschluss- und Konzernabschlussprüfung category.
