WIRTSCHAFTSPRÜFER

What WIRTSCHAFTSPRÜFER does

Wirtschaftsprüfung Stein GmbH Wirtschaftsprüfungsgesellschaft is a privately held German audit firm (GmbH) headquartered at Friedrichstrasse 95, Berlin. The firm is structured as a Wirtschaftsprüfungsgesellschaft with a headcount of seven employees and operates from a single domestic office. It is licensed to conduct professional auditing and attestation engagements under the German Institute of Public Auditors (IdW) framework, specifically Standards PS 480 and PS 490 governing special-purpose audits.

The firm's core offering centers on Sonderprüfungen (special audits) and Sonderbilanzen (special balance sheets), which are event-driven, typically non-recurring engagements triggered by corporate lifecycle events such as capital increases through contributions in kind, mergers, spin-offs, business formations, continuation forecasts, capital market orientation, insolvency assessments, and asset disposals. Adjacent services include valuation and due diligence (Bewertung und Due Diligence), restructuring and capital measures (Umwandlungsfälle und Kapitalmaßnahmen), non-financial and ESG reporting (Nichtfinanzielle Berichterstattung), and limited-assurance reviews of financial statements (Prüferische Durchsicht von Abschlüssen). Service delivery follows IdW Standards rather than a proprietary technology platform; no software products, AI tooling, APIs, or integration ecosystem are disclosed.

The business model is classic professional services: fees are determined per engagement based on scope and complexity, with no publicly disclosed pricing. Go-to-market is direct, targeted at German enterprises of all legal forms that require occasion-specific audit or attest work. The firm is privately held with no disclosed parent entity, investors, or funding history, and maintains no public subsidiaries, partnerships, or alliances in the available data.
