What We Offer

Complete compliance infrastructure

From country-specific payroll regulations to consolidation reports, AI tooling, and system integrations — everything needed to embed payroll into your platform.

Regional Consolidation

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.

Technology

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.

Payroll Adapters

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.

⇄ Bidirectional — import + export
→ Inbound — import only

Open Foundation

Commercial compliance.
Open-source core.

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.

🔍
Transparency
The payroll engine, calculation logic, and API are open source on GitHub. Every line is auditable.
🔓
No Runtime Lock-In
MIT license. The runtime is not proprietary. You can self-host, fork, or extend the platform independently — regulation maintenance is a separate, ongoing service.
Auditability
Tax and social security calculations are test-driven and verifiable. Every regulation ships with integration tests.
🌎
Community
Active OSS development, public issue tracker, and complete documentation at payrollengine.org.
