ESAC Certified

Tandem HR is certified by Employer Services Assurance Corporation (or ESAC).  ESAC is to the PEO world what FDIC is to the banking industry.  ESAC administers an accreditation program for the PEO industry to verify compliance with government regulations and important industry standards. Accredited PEOs, like Tandem, are backed by bonds providing financial assurance for clients, worksite employees, insurers and regulatory authorities.

ESAC-accredited PEOs submit audited financial statements and quarterly independent CPA verification of tax payment, benefit contributions and insurance premiums. Business owners deserve the peace of mind delivered with this type of financial backing.

Financial assurance to clients, worksite employees, insurers and regulatory authorities is provided through $1 million individual surety bonds covering each accredited PEO plus a $10 million excess surety bond. 

Ensure your PEO is ESAC bonded.   

At PEOcompare.com we strive to streamline the PEO selection process so that you, the small business owner, can escape the bordom of HR as quickly and painlessly as possible.
