About ESAC

The Employer Services Assurance Corporation (ESAC) is an independent nonprofit corporation that is the official accreditation and financial assurance organization for the PEO industry. ESAC is managed by a board of directors that includes PEO industry attorneys, CPAs and independent directors representing more than 100 years of combined PEO industry regulatory experience. The independent directors make the final decisions regarding PEO accreditation. Earning accreditation demonstrates a PEO’s financial stability, ethical business conduct and adherence to operational standards and regulatory requirements.


ESAC’s mission is to build integrity and trust and provide assurance to the PEO industry, so the industry can reach its full potential in support of America’s small businesses. To accomplish this, ESAC will:

  • Establish standards for ethical conduct, professional competency, and financial and operational reliability
  • Provide a credible program of accreditation based on independent verification of standards compliance
  • Provide financial assurance and notification programs to assure clients, employees and insurers of accredited PEOs and government authorities that accredited PEOs are in compliance with ESAC standards
  • Provide services to make PEO compliance with state and federal laws and regulations more time and cost efficient and reliable
