adfontis Steuerberatungsgesellschaft mbH

What adfontis Steuerberatungsgesellschaft mbH does

adfontis Steuerberatungsgesellschaft mbH is a German tax advisory firm (Steuerberatungsgesellschaft) headquartered in Bad Vilbel, Hesse, serving clients in the Rhein-Main region and across Germany. Founded in 2009 by Managing Director Anette Benzing and built on a predecessor practice dating to the 1960s, the firm is owner-managed and operates without external capital. Its core offering covers tax returns, financial accounting, payroll, annual financial statements, and succession/estate planning, with a documented specialization in Heilberufe — physicians, dentists, pharmacists, and other healthcare professionals — alongside services for small and medium-sized enterprises and private individuals.

The firm's technology stack is anchored in the DATEV software suite, formalized through DATEV Digitale Kanzlei 2024 certification. This supports digital document management, electronic invoicing, an online client portal, and digital personnel files, alongside conventional advisory workflows. Distribution relies on the firm website, content marketing (a YouTube series "Steuercockpit," newsletter, Facebook), and SEO, supplemented by referral through the affiliated Ärztliche Unternehmensgruppe Büdingen network. The firm is currently pursuing recognition as "Digitaler Arbeitgeber 2026" and has launched a Trainee-Programm and Duales Studium pathway (with accadis Hochschule Bad Homburg) to secure a long-term talent pipeline.

The business model is a fee-for-service professional services structure typical of mid-market German tax advisory: revenue is generated from recurring annual mandates for compliance (tax returns, payroll, financial accounting), supplemented by project-based fees for advisory engagements such as Unternehmensnachfolge. The firm employs approximately 17 staff, including two qualified Steuerberater (Anette Benzing and Marcel Arnold, who qualified in 2025 after joining in 2018) and dedicated payroll and accounting specialists. Growth is funded organically, with active hiring across bookkeeping, payroll, and trainee roles indicating capacity-led scaling rather than rapid expansion.
