Editor's Summary · PEO Software

No product in this PEO software category has user ratings on SpotSaaS yet — all are quotation-only with no verified review data. ADP TotalSource and ExtensisHR are widely recognized names in the professional employer organization space. The category spans a range of providers from regional specialists to global co-employment platforms.

PEO software enables small to mid-sized companies to co-employ their workforce through a professional employer organization, outsourcing payroll processing, benefits administration, workers' compensation, and HR compliance to a shared service provider. HR directors and COOs at companies with 10 to 500 employees that lack a dedicated HR department are the primary buyers.
