What Eggesiecker und Partner does

Eggesiecker und Partner is a Cologne-based German professional services partnership (Partnerschaftsgesellschaft) offering an integrated combination of tax advisory (Steuerberatung), statutory auditing (Wirtschaftsprüfung), and legal advisory (Rechtsberatung) under a single roof. Founded in 1973 by Prof. Dr. Fritz Eggesiecker, the firm is staffed by 7 partners and approximately 20 employees and serves mid-sized companies (mittelständische Unternehmen), high-net-worth individuals, sole proprietors and freelancers, and non-profit organizations across Germany. Core services include tax return preparation and strategy development, annual and consolidated financial statement audits, inheritance and gift tax planning, business succession and M&A transaction support, corporate restructuring, and legal representation before financial courts including the Bundesfinanzhof.

The firm operates on a fee-for-service professional services model with engagement-based and retainer billing consistent with German professional services standards, generating recurring revenue through ongoing advisory relationships. Go-to-market is exclusively direct: clients engage via the Cologne-Lindenthal office, phone, email, or a website contact form, with no resellers, marketplaces, or channel partners. The firm invests in employer branding through Facebook, Instagram, and XING and operates a streamlined 6-step online application process for recruitment. There is no proprietary technology platform; the firm uses standard professional services tooling (DATEV, SIMBA, Microsoft Office, ADVOWARE), and no AI/ML capability is disclosed. Recent activity has centered on generational succession, with multiple partner-to-employee transitions in 2022, 2025, and 2026 offset by the addition of new partner Lukas Bomke in 2024 and expansion of service lines including CFO as a Service and non-profit advisory.
