Payroll, benefits and HR software for PEOs and HR outsourcers
PrismHR builds the back-office platform PEOs and HR outsourcers use to run payroll, benefits and HR for small-business clients. Its stack is Microsoft-centric (.NET, C#, SQL Server, a deep Azure footprint) alongside PostgreSQL, Kubernetes and React/Angular front ends. Hiring tilts toward HR-domain specialists and support over engineering, and pain points cluster on payroll accuracy, tax compliance and open enrollment, pointing to an implementation- and service-heavy operating model.
