ETL-Krieger & Kollegen GmbH Steuerberatungsgesellschaft

What ETL-Krieger & Kollegen GmbH Steuerberatungsgesellschaft does

ETL-Krieger & Kollegen GmbH Steuerberatungsgesellschaft is a tax advisory firm (Steuerberatungsgesellschaft) established in Mainz-Kastel, Germany, operating as a member practice of the ETL-Gruppe – Germany's leading tax advisory group and one of the country's Top 5 auditing and tax advisory firms. The firm serves SMEs, freelancers, and self-employed professionals across the full business lifecycle (founding, expansion, succession), with documented specialization in hospitality and gastronomy (ETL ADHOGA), healthcare professionals (ETL Heilberufler), franchise systems (ETL Franchise), gas stations, professional athletes, e-commerce, agriculture and forestry, and retirees. With 7 employees, the firm operates a single office at Kurt-Hebach-Straße 5 in Mainz-Kastel.

The firm delivers a standard professional services portfolio (tax advisory, financial accounting, payroll, annual financial statements, business consulting) supported by a proprietary digital ecosystem. This includes PISA (cloud-based electronic client file), edtime (mobile time tracking and workforce scheduling), eMitarbeiter (employee self-service portal), Capitain (client portal), and integrations with DATEV (Germany's dominant accounting software), Vimcar (digital vehicle logbook), and SPENDIT (employee benefits card). The infrastructure is hosted on eurodata AG's ISO 27001/9001-certified high-availability data center in Saarbrücken. The firm markets through the ETL-Gruppe brand, SEO-optimized vertical landing pages, trade press contributions, and ETL-hosted events.

The business model is purely professional services revenue: recurring monthly/annual retainers for bookkeeping and payroll, project-based fees for tax filings and advisory, with pricing not publicly disclosed and custom-quoted per engagement. A free initial business consultation serves as a client acquisition mechanism. The firm relies on the ETL-Gruppe for cross-referrals, ETL Akademie for staff training, and ETL-Rechtsanwälte for integrated legal advisory. The firm benefits from ETL's network scale (970+ German offices, 1,470+ worldwide, 300,000+ clients, 15,600+ employees, €1.5B+ domestic revenue) but does not itself disclose standalone revenue or headcount growth trends.
