A PEO (Professional Employer Organization) is a company that offers co-employment with your company. They handle the administrative aspects of the employee and you handle the management and day-to-day of the workers. The PEO specializes in payroll, workers compensation, health benefits and human resources. Some PEOs have over 500,000 worksite employees. They have substantial purchasing power due to these numbers and they put those numbers to work for you. For more details, please visit our ‘What is a PEO?’ page.
