HRMQ is open-source HR and payroll administration for Dutch and EU employers, built on the OpenRegister data layer. Timesheets, expense claims, leave and verzuim (Poortwachter), onboarding through offboarding, and the only open-source Dutch payroll calculation engine — all audited by a versioned, machine-checkable labour and wage-tax rule corpus.
Timesheets, expenses, leave & verzuim, onboarding through offboarding, recruiting, performance reviews, an org chart, an asset register, and the open-source Dutch payroll engine — all backed by a versioned labour and wage-tax rule corpus.
A pure, stateless PayrollCalculator computes the NL Rekenvoorschriften 2026 chain in integer cents over a versioned nl-2026.json tax-year parameter file. occ hrmq:payroll:run creates draft runs and payslips; occ hrmq:payroll:verify audits them against the same rule corpus that audits hand-entered data.
Timesheets, expenses, leave requests, sickness cases, loonaangifte filings, pension UPA filings — every workflow is a declarative x-openregister-lifecycle state machine on the OpenRegister register, not bespoke PHP transition code.
occ hrmq:rules:audit reports enforced ÷ machine-checkable coverage across payroll, labour and privacy rule domains — Dutch labour law, EU directives, GDPR for employee data — sourced and cited, never invented.
