PayrollEx

What PayrollEx is

PayrollEx provides commercial payroll compliance infrastructure for organizations delivering payroll across multiple countries. It is aimed at EOR platforms, global payroll providers, payroll bureaus, and HCM platforms, and is built on the open-source Payroll Engine platform. The Payroll Engine calculation runtime, REST API, scripting engine, and toolchain are MIT-licensed and available to self-host and extend. Country regulation packages encode income tax, social security, local levies, employer costs, and statutory reporting, with annual updates. Full licenses support production payroll processing, statutory reporting, retro corrections, and legally binding results. Forecast licenses allow unlimited scenario-planning payruns at 30% of the Full license and transaction rate. Integration channels include pre-built adapters, an open REST API, and MCP-based access for AI agents. Adapters can import employee and contract data, while selected connectors export computed payroll results to ERP finance systems. Listed adapter systems include Dynamics 365, Sage, Odoo, AFAS, SAP SuccessFactors, Workday, Personio, PayFit, Silae, and CSV/JSON. Regulations include executable integration tests, statutory references, dated data, and a reproducible audit trail. Pricing is quoted by country and volume, per tenant; the products are described as being in beta, with partnerships invited for finalization.

Who it suits

PayrollEx is intended for EOR platforms, global payroll providers, payroll bureaus, and HCM platforms that need multi-country payroll compliance infrastructure. Its self-hostable open-source foundation may also suit teams that want to extend the underlying calculation runtime and toolchain.

Limits

Forecast licenses allow unlimited scenario-planning payruns at 30% of the Full license and transaction rate. Pricing is per tenant, and monthly transaction volume above 50,000 requires a custom agreement.

Getting started

1. Visit the PayrollEx website.
2. Contact the provider for pricing by country and volume.
3. Choose a license type, such as Full for production or Forecast for scenario planning.
4. Select integrations through adapters, the REST API, or MCP-based access.
5. Self-host or extend the MIT-licensed Payroll Engine components if needed.

Verdict

Consider PayrollEx if your organization provides payroll across countries and needs regulation packages, production processing, or forecast scenarios. Pricing requires a quote, and the product is in beta; teams seeking tax filing or multi-currency payments should note that these are not supported.
