What ACCONSIS does

ACCONSIS is a Munich-based, privately held integrated professional services firm operating across five interlinked disciplines: tax consultancy, legal advice, auditing, financing advice, and management consultancy. Founded over 60 years ago and rebranded under the ACCONSIS name several years ago, the firm serves more than 3,000 clients with a team of over 130 credentialed experts, delivered through a group structure of specialized GmbH entities covering tax (ACCONSIS GmbH Steuerberatungsgesellschaft), two audit entities (ACCONSIS GmbH Wirtschaftsprüfungsgesellschaft and ACCONSIS Audit GmbH Wirtschaftsprüfungsgesellschaft), legal (ACCONSIS GmbH Rechtsanwaltsgesellschaft), and financing (ACCONSIS GmbH Finanzierungsberatung). The customer base spans owner-managed Mittelstand SMEs, internationally operating companies, foundations and non-profits, startups, real estate owners, wealthy private individuals, and the hospitality sector.

The firm has no proprietary technology platform; its operating infrastructure consists of standard SaaS tooling including Microsoft Bookings for appointment scheduling, IONOS hosting, and common analytics stacks (Google Analytics, Meta Pixel, Google Tag Manager, Matomo). Specialized service lines extend the core practice into digital tax processes and procedural documentation (DATEV Label Digitale Kanzlei 2025), ESG and sustainability reporting, crypto/NFT blockchain tax advice, hospitality cash management, HR and accounting outsourcing, and company/asset succession. Thought leadership is distributed through a blog, newsletter, webinars, and active profiles on LinkedIn, Facebook, Instagram, YouTube, and XING.

ACCONSIS makes money entirely through professional services fees. Tax and legal mandates are billed under the regulated German fee schedules StBVV (Steuerberatervergütungsverordnung) and RVG (Rechtsanwaltsvergütungsgesetz); initial client engagement is low-friction via a free 15-minute introductory call or a paid first consultation at 249.90 EUR gross (one hour, online or in-person at the Munich office). The GTM is sales-led and relationship-driven, with a single dedicated contact person coordinating interdisciplinary teams across the five practice areas, supported by partnerships with DATEV, Allinial Global, Personio, Prohyp, DEHOGA, and IHK Munich. The firm is management-owned with no external investors, no disclosed funding rounds, and no public listing.
