PEO services perform a wide range of human resource outsourcing tasks, including payroll. In addition to payroll, PEO providers can also handle employee onboarding, training, benefits administration, recruitment, regulatory compliance, and more. You won’t necessarily get these types of services if you’re working with a traditional payroll provider.  If you’re just looking for a payroll option and don’t think you need a full-service PEO provider, check out our reviews of the best payroll services.
