Overview

Payroll Processing & Compliance runs the calculation, disbursement, and tax compliance of employee pay — withholding, multi-jurisdiction payroll tax filing, year-end reporting, and the software and service that surround it. Providers range from national service bureaus to modern payroll software and PEO-style bundles.

Unlike the rest of accounting, this is a concentrated, scale business: a small number of establishments employ a large workforce and process pay for a huge share of U.S. employees. Economics are software-like — per-employee-per-month pricing, very high recurring revenue, and float income earned on client tax funds held before remittance.

  • Float (interest on client tax deposits) is a meaningful, rate-sensitive profit lever.
  • Switching is painful — payroll is mission-critical and deeply integrated.
  • Software entrants (Gusto, Rippling, Justworks) are reshaping the low and mid market.

Geographic concentration
