Stolwijk Kelderman

What Stolwijk Kelderman does

Stolwijk Kelderman is a Dutch accounting, tax advisory, and legal advisory firm headquartered in Doetinchem, operating five regional offices across the Gelderland province (Doetinchem, Nijmegen/Wijchen, Arnhem/Zevenaar, Deventer, Twello). The firm holds a WTA-vergunning, the Dutch statutory audit license, enabling it to perform legally mandated audits for companies, municipalities, healthcare institutions, and not-for-profit entities. Its service portfolio is organized around three pillars: Accountancy (statutory audit plus an SMB/MKB practice with annual accounts, online bookkeeping, real-time business information, and part-time controlling), Fiscaal/Tax Advisory (business transfers, wealth and pension planning including DGA advisory, personal and family law, real estate tax, international/DE-NL cross-border tax, VAT, corporate and payroll tax), and Juridisch advies (legal advisory for businesses and individuals, including inheritance and divorce-related matters). Customer segments are hybrid and span SMB businesses (primary), municipalities, healthcare organizations, not-for-profits, individual entrepreneurs/DGAs, and German-Dutch cross-border clients.

The firm operates within Stolwijk Kennisnetwerk, a multi-discipline Dutch knowledge organization that bundles accountancy, tax, and legal services with adjacent specialty practices in HRM, occupational health, payroll, M&A advisory, data and BI, restructuring, and public-sector advisory. Stolwijk Kelderman is also a member of MSI Global Alliance, an international network of independent law and accounting firms in 100+ countries, which it uses for cross-border client referrals. There is no proprietary technology platform, no API or SDK exposure, and no disclosed AI/ML capabilities; the firm operates as a traditional professional services practice with sales-led go-to-market, quote-based pricing, and direct client engagement through regional offices and digital channels (website, newsletter, SKN Academy events and webinars, blogs).
