Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.
Professional employer organization
A professional employer organization (PEO) is an outsourcing firm which provides services to small and medium sized businesses (SMBs). Typically, the PEO offering may include human resource consulting, safety and risk mitigation services, payroll processing, employer payroll tax filing, workers' compensation insurance, health benefits, employers' practice and liability insurance (EPLI), retirement vehicles (401(k)), regulatory compliance assistance, workforce management technology, and training and development. The PEO enters into a contractual co-employment agreement with its clientele. Through co-employment, the PEO becomes the employer of record for tax purposes through filing payroll taxes under its own tax identification numbers.
