A professional employer organization (PEO) provides comprehensive HR solutions for small and mid-size businesses. Payroll, benefits, HR, tax administration, and regulatory compliance assistance are some of the many services PEOs provide to growing businesses across the country. Small businesses that work with a PEO grow 7 to 9 percent faster, have employee turnover that is 10 to 14 percent lower, and are 50 percent less likely to go out of business. The return on investment of using a PEO, in costs savings alone, is 27.3 percent.
