How to choose

Match the payroll tasks

Check the comparison fields for access to payroll data, payroll processing, pay calculation, and worker onboarding. These capabilities address different parts of a payroll workflow, so review the fields that match your need.

Check how it connects

Connection methods vary across the board. Products are listed for browser use, mobile devices, API access, self-hosted setups, or Linux. Confirm that the method fits the apps and systems you already use.

Review plans and pricing

Look for the free-plan and free-trial marks before committing. Paid pricing can be listed as a starting amount, while providers such as Argyle, Atomic, Check, and Flux Payroll API show pricing on request.

Check API and code terms

The board marks public API and open-source availability. For direct software connections or code inspection and changes, review the applicable mark and the tool's licence terms.

Confirm where it runs

A web product may suit browser-based work, while an API connection is aimed at linking software. Mobile, self-hosted, and Linux labels indicate other ways a product can run, so compare them with your setup.
