Unified HR Marketplace Platform for Payroll Providers
An API-driven marketplace connecting payroll providers to the HR tools their customers operate every day, with a partner integration system that scales.
Payroll providers, PEOs, and ASOs often face fragmented HR technology stacks and limited internal infrastructure, making it difficult to offer a broad integrated service suite. In this engagement, we engineered a unified, API-driven HR marketplace that consolidated pre-verified applications into a configurable platform.
The system centralized payroll-adjacent services, automated data exchange across tools, and removed redundant workflows, enabling providers to scale offerings without compounding operational complexity.
The decision
The decision was to create one configurable marketplace layer rather than expand through a larger collection of disconnected point solutions. Pre-verified applications, service configuration, and automated data exchange would share an API-driven foundation so providers could broaden their offerings without multiplying manual workflows.

Insights Earned Across Industries
Every industry has its own language. But many of the hardest software problems repeat: messy workflows, disconnected systems, complex permissions, reporting gaps, and users who need better tools to do their jobs. Stratos works across healthcare, financial services, benefits, logistics, real estate, education, music technology, and other operationally complex sectors. That breadth gives us more than category familiarity. It gives us a working library of proven patterns. Clients benefit not only from what we understand about their industry, but from what we have already solved in others.
Reusable lessons. Faster decisions. Stronger software.
