ADP Payroll is a set of payroll products and services under ADP (Automatic Data Processing) designed to calculate pay, withhold and remit taxes, generate pay stubs and year-end forms (W-2/1099), support direct deposit and other pay methods, and integrate payroll with broader HR functions (time tracking, benefits, reporting, compliance workflows). ADP’s payroll offerings span small business through enterprise, with notable products including:
- **RUN Powered by ADP®** (typically SMB payroll + basic HR)
- **ADP Workforce Now® Payroll** (mid-market payroll within a broader HCM suite)
ADP describes these offerings as covering payroll, tax filing, and HR integrations, and provides an ecosystem (ADP Marketplace) of add-ons and integrations.
