A PEO, or Professional Employer Organization, is a company that provides a range of HR and employment services to small and medium-sized businesses. PEOs offer a full range of HR services, including payroll, benefits, HR compliance, and risk management, as well as support and consulting services.

PEOs work with businesses to manage their HR functions and responsibilities, allowing the business to focus on its core operations. PEOs typically enter into a co-employment arrangement with their clients, meaning that they become the employer of record for tax and liability purposes while the client retains control over its day-to-day operations and employees.

PEOs can be a cost-effective solution for small and medium-sized businesses that do not have the resources or expertise to manage HR functions in-house. They can also provide access to a range of HR services and benefits that may not be available to smaller businesses on their own.

PEOs can be a good fit for businesses of all sizes, but they are particularly useful for small and medium-sized businesses that may not have the resources or expertise to manage HR functions in-house. They can also be a good option for businesses that are looking to reduce costs or improve efficiency in their HR operations.
