NAPEO (National Association of Professional Employer Organizations)
The U.S. trade association for the PEO industry, publishing research, advocacy, and standards used by buyers and brokers to evaluate PEOs.
NAPEO is the industry trade association representing Professional Employer Organizations in the United States. It publishes economic research on the PEO industry, lobbies on federal and state regulation, and maintains educational programs for member firms.
NAPEO membership is one signal — though not a guarantee of quality — that buyers and brokers use during PEO evaluation. NAPEO research is widely cited in PEO comparison content and procurement decks.
