A PEO and HRO are commonly used together, but they are, in fact, completely different entities. Human Resource Outsources (HRO) are similar to PEOs, but they are limited to only HR services.  In contrast, a PEO handles that and far more, offering a comprehensive and flexible setup for your company that aims to resolve all of your administrative, regulatory, and HR needs. This also means that a PEO is given significantly more autonomy over the business, having the authority to handle payments, training, hiring, and benefits, while an HRO’s power extends only as far as the HR-related aspects of the job.
