What is a Professional Employer Organization (PEO)? A Professional Employer Organization (PEO) handles employee administrative functions on an “outsourced” basis for your business. These functions include payroll, benefits administration, human resources, workers’ compensation and risk management. The “Concept” is simple. You enter into a “Co-Employer” relationship. You remain the “Business Employer.” You retain the right to hire, terminate, supervise, direct and set policies for your employees. You maintain care, custody and control of your workforce. OneSource as the PEO becomes the “Administrative Employer” or W-2 Statutory Employer of Record. The “Co-Employer” relationship enables you to focus on your core business and outsource the non-revenue employee administrative details to OneSource saving you both time and money! What is the ASO Concept? OneSource understands that the PEO option may not be the solution for every business. An alternative to the PEO model is the “Administrative Services Outsourcing” or ASO option. An ASO (also commonly referred to as “Business Process Outsourcing”) provides employee administration without the “Co-Employer” relationship. OneSource has several years of experience administering ASO accounts. The services available in the PEO model are also available in the ASO model.
