ABG Partner

What ABG Partner does

ABG Partner is a German integrated professional services firm operating under the umbrella of the ABG Verbund, delivering tax advisory (Steuerberatung), statutory audit (Wirtschaftsprüfung), management consulting, legal advisory (via the Cramer Bender Rechtsanwälte partnership), and business services (marketing, real estate management, and in-house data center operations). The legal anchor entity is ABG Steuerberatungsgesellschaft mbH, headquartered in Munich, with branch offices in Dresden, Bayreuth, Berlin, and Böblingen. Specialized wholly-owned subsidiaries handle auditing (ABG Revisions- und Treuhandgesellschaft mbH), consulting (ABG Consulting-Partner GmbH & Co. KG), marketing (ABG Marketing GmbH), real estate management (ABG Immobilienmanagement GmbH), and IT/data center services (ABG Software Solutions).

The firm targets the German Mittelstand as its primary client base, alongside corporations, foundations, freelancers, and high-net-worth individuals. Its service portfolio covers full-scope tax advisory including financial accounting, payroll, annual financial statements, and wealth planning; statutory audits under HGB and IFRS; and management consulting spanning business valuation, restructuring, insolvency advisory, interim management, M&A, succession planning, financing, and bank rating optimization. The firm operates its own data center facilities in Munich, Dresden, and Bayreuth for audit-compliant data storage, and holds DATEV 'Digitale Kanzlei' certification — a credential held by only ~1,500 of ~50,000 German tax practices. It has been recognized in the Handelsblatt / S.W.I. Finance 'Beste Steuerberater' ranking in both 2023 and 2025.

Revenue is generated exclusively through professional services fees, with standard tax advisory fees regulated under the Steuerberatervergütungsverordnung (StBVV) and non-regulated services priced by agreement. Distribution is entirely direct, served by qualified Steuerberater, Wirtschaftsprüfer, and consulting specialists across the five offices. Go-to-market relies on reputation, referrals within the German business community, content marketing through the Akzento Mittelstandsmagazin and Restart Magazin publications, website/blog articles, LinkedIn, and client newsletters (Mandantenrundschreiben). The firm is privately held under a partnership structure with no external private equity or venture capital backing indicated.
