Due diligence checked November 4, 2026. We only list carriers and partners that a filing, the provider or a named review states. Many PEOs do not publish their carriers or recordkeepers, so "not publicly listed" means we could not find it, not that none exists. If something is missing, request a quote and we will get it from the PEO for you. Lineups vary by state and change at renewal.

- Who is the workers' comp carrier, how are rates set, and what happens to my experience rating if I leave?
