Production-ready compliance infrastructure for multi-country payroll. Regulations, technology, and integrations — built on the open-source Payroll Engine platform.
From country-specific payroll regulations to consolidation reports, AI tooling, and system integrations — everything needed to embed payroll into your platform.
Each regulation covers the full statutory scope for one country — income tax, social security, local contributions, and employer costs. Regulations are updated annually and ship with integration tests that verify every calculation against real statutory logic.
Consolidation regulations aggregate payroll results across multiple countries into unified reports — employer cost summaries, statutory totals, and cross-entity comparisons. Each region runs as a separate tenant layer on top of the individual country regulations.
Commercial tooling that connects AI assistants directly to the Payroll Engine platform. MCP Server Pro extends the read-only OSS server with full write access — so AI can author regulations, run payruns, and execute consolidations. AI Context Pro provides structured LLM context for regulation development workflows.
Connectors that import employee master data from HR and ERP platforms into Payroll Engine and, for bidirectional connectors, export computed payroll results back as journal entries or result files. All adapters handle authentication, delta synchronization, and field mapping. Outbound result export is available for Odoo, Microsoft Dynamics 365, AFAS, Sage, CSV, and JSON.
Every PayrollEx product runs on the Payroll Engine open-source platform (MIT). The calculation engine, REST API, and toolchain are fully auditable — no black box.
PayrollEx serves everyone in the payroll value chain — from platform providers to payroll consultants to DevOps engineers.
