ADIUVIS

What ADIUVIS does

ADIUVIS is a private German professional services firm operating as a multi-partner consulting alliance headquartered in Marktredwitz, Bavaria. The firm delivers 360-degree business advisory to German Mittelstand companies and family-owned businesses, bundling five service disciplines under one umbrella: tax advisory (Steuerberatung), statutory and voluntary auditing (Wirtschaftsprüfung), legal advisory (Rechtsberatung) covering corporate, contract, M&A, and labor law, consulting and transformation (strategy, organizational design, succession planning, performance management), and digital services (digital document management, payroll digitization, ERP interface automation, and reporting dashboards). The alliance is structured as a network of ADIUVIS-owned entities and partner firms (Jäckel, Bauer, activa, Schedl, and Gerhard Schurig und Partner) operating from seven office locations across the Oberpfalz and Fichtelgebirge regions, serving more than 5,000 clients.

The business model is a relationship-driven professional services practice with no public pricing, no standardized engagement tiers, and revenue generated entirely through fee-based advisory mandates. Distribution is exclusively direct: partners and senior advisors engage clients through personal, on-site consultation, supplemented by content marketing (corporate website, SEO-optimized service pages, blog) and word-of-mouth referrals within the regional Mittelstand business community. The technology backbone relies on DATEV (Germany's leading professional accounting and tax platform) and Simba accounting software for client deliverable production and tax authority data exchange, with digital document management and cloud-based workflow tools supporting internal operations. There is no proprietary software product, no public-facing API, and no consumer-facing application.

ADIUVIS is founder-managed by Gerhard Schurig (Geschäftsführer) alongside a partner group of nine named individuals and is independently held with no disclosed private equity, venture capital, or institutional investor participation. The alliance model was formalized in 2025/2026 as a deliberate shift from single-firm operations to an integrated multi-partner structure, positioning the firm against national competitors by combining regional proximity with the multidisciplinary capability set typically associated with larger advisory networks.

Core offering

ADIUVIS Consulting Alliance provides integrated 360-degree business advisory to the German Mittelstand and family businesses across five disciplines: tax advisory (compliance, planning, succession structuring), auditing (statutory and voluntary audits), legal advisory (corporate, contract, M&A, labor law), consulting and transformation (strategy, organization, performance management), and digital services (document management, accounting, payroll automation, reporting). Services are delivered directly through seven partner offices in Bavaria, supported by DATEV and cloud-based digital workflows.

Product overview

ADIUVIS Consulting Alliance is a unified consulting alliance offering five integrated service modules under one umbrella brand: Steuerberatung (tax advisory), Wirtschaftsprüfung (auditing), Rechtsberatung (legal advice), Consulting & Transformation (strategy and organizational consulting), and Digitale Services (digital finance and HR solutions). The Alliance positions itself as a 360-degree business consulting provider for the Mittelstand, where these disciplines are designed to interconnect — for example, tax planning is coordinated with legal structuring, and digitalization is aligned with strategic growth objectives. The core offering is advisory services rather than standalone software products, with the Alliance brand serving as the overarching product wrapper.
