## How to choose

- Preview before payroll approval: Check that a payroll can be previewed with its totals and tax lines before it is approved, since approving a run is the step that moves money.
- Human approval before payroll runs: Check which approvals a person must give before an agent can submit or approve a run, since the approval route decides who is accountable for pay.
- Steps before live payroll: Check what onboarding, partner agreement or consent sits between a sandbox and live payroll, since an integration cannot run for real employees until those steps are complete.
- Country and worker type coverage: Check which countries and worker types the API covers for onboarding and pay, since contractors and staff in an uncovered country cannot be paid through the same agent flow.

- How the benchmark tests this category: One test employer with three workers in each listing's sandbox. The same tasks run through its API (onboard a worker, enter hours, preview a payroll, approve it, read the pay statements). We check the calculation preview, approval steps and the onboarding needed for production. In this run listings are graded from public evidence against the published checklist.
