Humaans / Case study
US payroll integration
From evaluating providers to coordinating four engineers: leading a payroll integration that belonged in the HR platform, across profiles, compensation and documents.
OutcomeLaunched with Check, led through rollout and supported sales conversations with technical and payroll expertise.
The problem
Humaans wanted to expand into the US market, where customers expected payroll to be part of their HR platform. The CTO supplied a shortlist of potential providers; I owned the assessment and led the integration through rollout.
Choosing a provider that fit
I worked with sales to understand what prospective customers expected from payroll. I assessed the shortlisted providers against those needs and how their APIs mapped to the data in Humaans.
I selected Check because its API aligned well with our data model and it had strong webhook infrastructure. The alternatives had API surfaces that were harder to understand and explain in relation to their underlying data. Check gave us a clearer foundation for integrating payroll into the product.
Turning the integration into a team plan
I designed how payroll would connect with employee profiles, compensation and documents, aiming for a coherent product experience. We connected Check’s webhooks with our own infrastructure.
I broke the work into achievable milestones and distributed implementation across four engineers. Their involvement varied as the team balanced other priorities, so the work needed clear boundaries and a shared direction.
Through to rollout
The integration launched, and I led the project through rollout. I also joined sales calls to support the technical discussion and answer complex payroll questions, connecting implementation knowledge with the conversations customers were having.
