BSS GmbH Steuerberatungsgesellschaft

What BSS GmbH Steuerberatungsgesellschaft does

BSS GmbH Steuerberatungsgesellschaft is a privately held German tax advisory firm (Steuerberatungsgesellschaft) founded in 1989 and headquartered in Cologne, with a secondary office in Euskirchen. The firm serves companies across North Rhine-Westphalia, with a primary focus on German Mittelstand enterprises and secondary specializations in the hospitality/gastronomy and real estate investor segments. It operates with 16 employees under three managing directors (Norbert Schaab, Julian Tönnesmann, and Kristin Tesch), all credentialed Steuerberaters.

The firm delivers five integrated service pillars — Steuerberatung (tax advisory), Jahresabschlüsse (annual financial statements), Finanzbuchhaltung (financial accounting), Lohnbuchhaltung (payroll accounting), and Betriebswirtschaftliche Beratung (business advisory) — accessible through a Digitale Steuerberatung platform powered by DATEV Unternehmen Online for cloud-based document exchange, digital receipts, and remote collaboration via BlueJeans video conferencing. Differentiated offerings include a structured 360-degree client care cycle and specialized expertise in complex payroll scenarios for seasonal workers (mini-jobs, tip documentation) and real estate tax structuring.

BSS generates revenue through professional service fees determined under the German Steuerberatervergütungsverordnung (StBVV) and individual fee agreements per §4 DL-InfoV, billed on a per-engagement or multi-year retainer basis. The go-to-market is sales-led and relationship-driven via direct office-based consulting in Cologne and Euskirchen, supported by content marketing through the Steuer-Blog and organic search. The company is founder/management-owned with no venture capital, private equity, or parent company involvement.

Broad incumbents

• ETL AG: ETL AG is Germany's largest tax advisory franchise network, with hundreds of partner offices across Germany. Comparable to BSS as a Steuerberatungsgesellschaft serving Mittelstand clients with full tax, payroll, and bookkeeping services, but at far greater scale and geographic reach.
• BDO AG Wirtschaftsprüfungsgesellschaft: BDO Germany is a top-tier accounting and tax advisory network with deep Mittelstand coverage. Overlaps with BSS across tax advisory, payroll, annual accounts, and business consulting, though at a much larger scale with audit capabilities BSS does not offer.

Emerging players

• Taxfix GmbH: Taxfix is a Berlin-based digital tax filing app targeting consumers and freelancers. Adjacent competitor pressure on the lower end of the market; illustrates the digital-first disruption BSS must respond to with its own DATEV-enabled digital tax advisory offering.

Others
