Groenendijk Onderwijs Administratie

What Groenendijk Onderwijs Administratie does

Groenendijk Onderwijs Administratie is a Dutch administration services provider specializing in payroll, finance, HR, and back-office administration for school boards (onderwijsbesturen) in the Netherlands. The company has operated for more than 60 years and serves 160+ school boards with a team of 140+ employees, offering core administration products that handle the regulatory and collective-labor-agreement (CAO) complexity specific to Dutch public-sector education.

Its product stack centers on administration modules — covering salary processing, personnel administration, financial administration, and the Onderwijsdashboard reporting/insight layer — and is built around deep compliance with ISAE assurance standards and Dutch education-funding flows. Technology and service partnerships with Visma and insurance partners extend the platform into adjacent back-office domains for schools.

The go-to-market is a long-cycle, relationship-driven model targeting Dutch school boards through recurring administration contracts and add-on services. Leadership includes Maikel Adriaansen, Stephan Breur, and Wouter Renden. The company does not appear to have raised external growth equity, indicating a self-funded, cash-generative services business rather than a venture-backed growth profile.

Broad incumbents

• ADP Nederland: Global payroll and HR outsourcing provider with Dutch presence serving multi-country employers. Comparable on payroll outsourcing but at much larger scale and across industries.
