pays per control

A metric tracking the organic change in the number of employees paid by existing clients.

Pays per control (PPC) is a key operational metric used by payroll and human capital management (HCM) providers to measure organic employment growth within their existing client base. Unlike new client acquisitions, which represent new business bookings, PPC measures whether existing clients are hiring or laying off workers. For investors, PPC serves as a highly sensitive, real-time indicator of labor market health and economic expansion. When PPC is growing, it indicates that businesses are expanding their workforces, which naturally increases the payroll processor's transaction volumes and revenues without requiring additional sales acquisition costs. Conversely, flat or negative PPC growth signals a cooling labor market or corporate belt-tightening. It helps investors isolate the organic growth of the underlying economy from growth driven by new software sales, price increases, or acquisitions.

A payroll processor's existing clients collectively employed 1,000,000 workers last year and now employ 1,020,000 workers. The pays per control growth rate is calculated as: (1,020,000 - 1,000,000) / 1,000,000 = 0.02, or 2%.
