What DORNBACH does

DORNBACH is a privately held, owner-managed German professional services group headquartered in Koblenz and founded in 1954. The firm delivers integrated Wirtschaftsprüfung (auditing), Steuerberatung (tax advisory), Rechtsberatung (legal advisory), and Unternehmensberatung (management consulting) through approximately 25+ managing partners and 800-850+ employees across 20+ German office locations. Core products include statutory and consolidated audits per IDW S1, corporate and personal tax advisory, transfer pricing and international tax services including Pillar Two compliance, M&A advisory and purchase price allocation, ESG/CSRD sustainability reporting, and specialized sub-brands such as DORNBACH-Med (healthcare), DORNBACH Transfer Pricing, DORNBACH Consulting, and Dornbach Valuation. The firm markets itself as one of Germany's Top 10 owner-managed professional services firms and combines audit, tax, legal, and consulting under a single brand to serve family-owned Mittelstand companies, regulated enterprises, public-sector entities, and international firms with cross-border exposure.

Underlying technical infrastructure is modest and typical of professional services rather than a technology platform. DORNBACH uses Python and VBA for quantitative-stochastic valuation modeling (including embedded derivatives, convertible bonds, earn-outs, and ESOP/VSOP scenarios), runs AI Systems Auditing engagements under the IDW PS 861 framework, and operates IT-audit and IT-assurance through DORNBACH IT Systems AG. Customer-facing technology is delivered via its main website (dornbach.de), multilingual DE/EN/CN, with a separate career portal (karriere.dornbach.de) and an events/online-seminar function used as lead-generation channels.

The business model is classic professional services: time-and-engagement-based fees across the four practice lines, partner-led client coverage through the field office network, and recurring annual mandates driven by statutory audit and tax filing cycles. DORNBACH monetizes revenue through its wholly-owned operating subsidiaries (DORNBACH GmbH WPG, RAG, Treuhand KG, Consulting GmbH, Transfer Pricing GmbH, Health Care GmbH, IT Systems AG, Valuation GmbH, Tax & Legal Solutions) and through a holding intermediate, SW Germany GmbH, which serves as the European gateway for the ShineWing International network. International reach is provided via the SW International partnership (joined 2018/2019, first European member) covering 22 member firms across 13 countries, with dedicated China Desk and French Desk services at the Frankfurt regional headquarters.
