About Us

What is ESAC?
The Employer Services Assurance Corporation (ESAC) is the accreditation and financial assurance organization for the Professional Employer Organization (PEO) industry. ESAC provides independent verification of a PEO’s reliability.

ESAC is an independent, nonprofit corporation managed by a board of directors comprised of independent directors (including former regulators of the PEO industry), advisory directors and industry executives.

Accreditation through ESAC demonstrates a PEO's financial stability, ethical business conduct and adherence to operational standards and regulatory requirements.

ESAC Purpose:

Build integrity and trust and provide assurance for the PEO industry.

ESAC establishes standards for ethical conduct, professional competency, and financial and operational reliability.

ESAC provides a credible program of accreditation based on independent verification of standards compliance.

ESAC provides financial assurance and notification programs to assure the clients, employees and insurers of accredited PEOs and government agencies that accredited PEOs are in compliance with ESAC’s standards.

ESAC provides services to make PEO compliance with state and federal laws and regulations more time and cost efficient and reliable.

PEO Accreditation

ESAC's accreditation program verifies a PEO's ongoing financial stability, ethical business conduct and compliance, and adherence to operational standards, government regulations and important industry standards.

Financial Assurance

Similar to the FDIC for the banking industry, SIPC for the securities industry, and state insurance guaranty associations for the insurance industry, an accredited PEOs' performance of key employer responsibilities to their clients, worksite employees, insurers and regulatory authorities is backed by over $15 million of surety bonds held in a trust at a national bank.

Regulatory Compliance

ESAC offers accredited PEOs and state regulatory agencies access to its online compliance services. PEOs can quickly comply with state licensing requirements using data already submitted through ESAC's secure systems. State agencies can access required information authorized by the PEO through a secure portal.
