Steffen & Partner Gruppe

What Steffen & Partner Gruppe does

Steffen & Partner Gruppe is a multi-disciplinary German professional services firm founded in 1978 in Bocholt, structured as a partnership (Steffen & Partner Steuerberatungsgesellschaft PartG mbB) operating alongside legally independent but unified group entities for audit (Steffen & Kollegen GmbH Wirtschaftsprüfungsgesellschaft, I-ADVISE AG Wirtschaftsprüfungsgesellschaft), legal (Steffen Rechtsanwaltsgesellschaft mbH), tax advisory (I-Advise Tax Steuerberatungsgesellschaft mbH), trust and advisory (SD Wirtschaft, Treuhand und Steuerberatungsgesellschaft mbH), and education/consulting (Steffen Akademie & Beratung GmbH). The firm employs 34 staff including 12 Berufsträger:innen and delivers tax advisory, audit, legal, and business consulting services from its Bocholt headquarters and two Düsseldorf offices, serving families and family-owned businesses, German subsidiaries of international corporations, industrial and construction companies, and private individuals nationwide.

The core offering is integrated, multi-disciplinary mandates coordinated by a single Ansprechpartner per client, covering tax compliance and declaration, annual financial statements under HGB/EStG, payroll including specialized construction wages (Baulohn), audit and due diligence, succession planning, M&A Tax advisory, international tax law (transfer pricing, holding structures, expatriate), employment and civil law, business mediation, and strategic consulting. Underlying technology is the standard DATEV ecosystem for tax and accounting, complemented by the proprietary SUP Connect client portal for secure document exchange and integrations with DATEV DUO (cloud accounting) and KanzleiDrive (document management). Distribution is via office consultation, on-site vor-Ort-Service, and the encrypted digital portal.

The revenue model is professional services fees: time-based billing for individual consultation, flat-fee (Pauschalpreis) pricing for payroll processing, and project/engagement fees for advisory mandates — quote-based and not publicly disclosed. The go-to-market is sales-led and reputation-driven, with no paid advertising channel visible; instead the firm relies on 17 consecutive Focus Money Top-Steuerberater awards (2009-2026), four Exzellenter Arbeitgeber recognitions (2022, 2024, 2025, 2026), professional association memberships (DStV, Steuerberaterkammer Westfalen-Lippe, DAV), a Wissens-Hub content channel, and a published Kanzleimagazin. Partnerships are concentrated inside the group network and with technology vendors (DATEV, Cloudflare, netcup, CleverElements).
