Welcome to Symmetrical Rails

Symmetrical Rails is a powerful REST API that gives any developer access to world-class, international payroll infrastructure that can be embedded directly into any software. We enable you to run payroll for your clients, read payroll data, access payroll cashflows but also to programatically hire people, all in a few lines of code. Single integration covers multiple geographies.
