Stolp+KAB

What Stolp+KAB does

Stolp+KAB adviseurs en accountants B.V. is a privately held Dutch accounting and advisory firm headquartered in Roelofarendsveen with a second office in Voorburg. The firm delivers four core service lines — accountancy, administration, advice, and audit — to small and medium-sized enterprises, entrepreneurs, startups, and retirees across the Netherlands, with international reach enabled through its Russell Bedford International membership (290+ members, ~100 countries). It holds an AFM license authorizing statutory audit engagements, is a member of SRA, and markets an integrated offering spanning financial administration, payroll, fiscal, legal, HR, financial planning, and business transfer advisory. The 2016 merger of KAB West with Stolp consolidated the two regional brands under unified ownership, combining over 150 years of cumulative heritage (Stolp founded 1938, KAB roots to 1946).

The business model is professional services, billed on a quote-based, scope-driven engagement model with monthly cadence for recurring work. Go-to-market is direct, relationship-led sales targeting the Dutch MKB through two physical offices, complemented by LinkedIn, Instagram, an SRA newsletter, a recruitment site, and RBI network referrals. Revenue is diversified across accounting, tax advisory, audit assurance, financial advisory, payroll administration, and legal/HR advisory, with named clients spanning automotive, healthcare, ICT, food logistics, bakery, real estate, software, and transport. Technology stack centers on digital administration systems and a proprietary management tool for startup clients, with no disclosed AI/ML capabilities, proprietary software products, or platform architecture. The firm operates with 101–250 employees, is owned by its directielid partners (Roy ter Heijden, Kevin Kuiper, Michiel Polman, Edwin Kleefstra), and has experienced a leadership disruption with the May 2024 passing of long-tenured directielid Marco van der Zwet.
