A PEO, or Professional Employer Organization, is a company that enters into a co-employment relationship with a business, taking on shared employer responsibilities for payroll, benefits, HR compliance, and risk management. This allows small and mid-size businesses to access enterprise-level HR infrastructure without building it internally.

Q: How does PEO payroll software work?

PEO payroll software processes payroll in real time, automatically calculates and files federal, state, and local payroll taxes, manages direct deposits, and generates W-2s and 1099s. Because it is integrated with benefits and compliance systems, it eliminates manual reconciliation across separate platforms.

Q: How much does a PEO cost?

PEO pricing is typically structured as either a per-employee-per-month (PEPM) fee or a percentage of total payroll wages. INFINITI HR offers flexible, client-centric pricing models tailored to company size and the specific services and benefits selected.

Q: What is the difference between a PEO and an ASO?

A PEO enters a co-employment relationship, sharing legal employer responsibilities and liability with the client business. An ASO (Administrative Services Organization) provides similar HR, payroll, and benefits administration services, but the client company remains the sole legal employer of record. PEOs typically offer access to master insurance policies and benefits plans that ASOs cannot provide.
