What H/W/S does

HWS is an independent German professional services firm headquartered in Stuttgart that delivers an integrated portfolio of tax advisory, statutory and voluntary auditing, legal services, and adjacent consulting (M&A and due diligence, company valuation, transfer pricing, succession planning, crypto/blockchain advisory, start-up consulting, and international tax structuring) to medium-sized companies, high-net-worth individuals, liberal professionals, start-ups, and international clients, particularly Japanese subsidiaries in Germany. The firm operates as a partnership-led network of 38 wholly-owned group entities spanning 20+ physical offices across southern Germany — including Stuttgart, Reutlingen, Tübingen, Ulm, Sindelfingen, Karlsruhe, Heilbronn, Korb, Remshalden, Nürtingen, Heppenheim, Landau, and others — supplemented by international cooperation offices in Zurich (Wisler Legal partnership), Milan (HWS Italy), and Shanghai (Zhongxi CPAs). Founded in 1923 by Albert Haussmann, one of Germany's first auditors, the firm traces its heritage to a century of continuous operation in southwest Germany.

The technology backbone centers on the DATEV accounting software ecosystem, GoBD-compliant digital document management, XRechnung e-invoicing standard, and the proprietary divedo procedural documentation platform (delivered through divedo GmbH). Multiple HWS entities hold DATEV "Digitale Kanzlei" certifications for digitalization excellence; HWS Ulm holds DIN EN ISO 9001:2015 quality certification. The firm also operates specialized subsidiaries including SNIT GmbH & Co. KG for IT services and ERP integration, and HWS Crypto GmbH for blockchain and NFT tax advisory. Integration of new acquisitions follows a standardized quality and digitalization framework propagated across the group.

Commercially, HWS runs an enterprise field sales motion with partner-led relationships at each location, pricing structured around the statutory Steuerberatergebührenverordnung (StBVV) fee schedule for tax work and project-based or flat-rate fees for valuation and M&A engagements. Annual recurring engagements dominate tax compliance and audit revenue, while project work anchors M&A and valuation practices. Marketing combines a comprehensive bilingual website, the tax-i client newsletter, expert tax-online articles, video content, LinkedIn/XING/Instagram presence, ForumW event sponsorship, and published Fachartikel/Fachbücher. International work is delivered through the Praxity Global Alliance (access to 120+ countries) and direct partnerships with HLS Global Group (Japanese Desk) and country-specific cooperation partners.
