About Payroll Shack
Payroll Shack is building modern payroll infrastructure for software teams and accounting firms — REST APIs, MCP tools, white-label portals, and employee endpoints so you can ship payroll under your brand without rebuilding compliance from scratch.
Our mission
Payroll is complex, jurisdiction-specific, and constantly changing. We believe integrators, platforms, and firms deserve clear APIs, honest documentation, and white-label options they can provision in minutes — not months. The developer portal lets you create companies, issue keys, meter usage, brand the experience, and connect agents through MCP.
