PrismHR provides technology to the HR outsourcing industry, serving Professional Employer Organizations (PEOs) and payroll bureaus. Its software platform is the backbone for firms that manage payroll, benefits, and HR administration on behalf of small and medium-sized businesses (SMBs). The company's core business is enabling these outsourcers, not selling directly to the end-client employers.
The PrismHR Platform is a comprehensive system that handles recruitment and onboarding automation, payroll processing, benefits administration, compliance management, and performance tracking. This unified approach allows HR outsourcers to offer a full suite of services to their SMB clients through a single technology stack.
The scale of PrismHR's infrastructure is significant. Its platform supports over 100,000 client businesses and approximately 2 million employees across the United States. The company processes more than $30 billion in annual payroll and claims to operate the largest network of HR outsourcers in the country. Founded in 1984, the company has been building and refining its systems for four decades.
