A PEO’s economy of scale enables each client company to lower employment costs and increase the business’s bottom line. The client can maintain a simple in-house HR infrastructure or none at all by relying on the PEO. The client also can reduce hiring overhead. The professionals at the PEO can provide critical assistance with employer compliance, which helps protect the client against liability. In many cases, the client can pay a small up-front cost for a significant technology and service infrastructure or platform provided by the PEO. In addition, the PEO provides time savings by handling routine and redundant tasks for its clients. This enables the business owner to focus on the company’s core competency and grow its bottom line.
