For small and mid-sized businesses (SMBs), growth often comes with growing pains: more compliance risk, complex HR tasks, and limited time for strategy. That’s where Professional Employer Organizations (PEOs) come in—and a new 2017 study from the National Association of Professional Employer Organizations (NAPEO) shows how much they help.
Based on surveys of over 1,500 employees and 100 businesses, the report compares companies that use PEOs with those that don’t—uncovering major differences in growth, profitability, employee satisfaction, and more.
Companies that work with a PEO report significantly better financial performance. The study found that PEO clients had twice the median revenue growth of comparable non-PEO firms. They also projected 40% greater expected revenue growth year over year and were 16% more likely to report increased profitability.
These gains are directly tied to what PEOs offer: outsourced support for HR, payroll, benefits administration, and compliance. By removing these time-consuming burdens, business leaders can focus on growth initiatives, customer service, and innovation.

These results suggest that PEOs streamline HR and help companies build more attractive, supportive workplaces, especially over time.
Business owners overwhelmingly recommend PEO partnerships.
In the survey, 98% of PEO clients said they would recommend a PEO to a fellow small business owner. Most also credited their PEO with helping them increase revenue and profitability—reinforcing the idea that PEOs are more than just a back-office service.
This report offers clear evidence that PEOs drive measurable impact in the areas SMBs care about most: growth, employee retention, HR efficiency, and peace of mind.
Here’s a quick summary of what stands out:
If you’re evaluating whether a PEO is worth the investment, this study offers a clear answer: it’s a proven path to better outcomes for many growing businesses.
