One of the most compelling reasons businesses turn to a Professional Employer Organization (PEO) is the significant cost savings outsourcing can provide. Direct savings can result from reducing Human Resources headcount, systems and software expenditures. Those are savings business owners expect and understand, but there are other savings opportunities that may not be as apparent. Because PEOs pool their clients’ employees to procure health and workers’ compensation insurance, as well as other benefits such as vision, dental, and savings plans, PEOs can often receive highly discounted rates. Those economies of scale enable PEOs to pass significant savings onto their clients.
