Pricing. Both quote. RUN lists extra fees, such as W-2 and 1099 forms and higher fees for off-cycle payrolls; ADP TotalSource publishes no fee list on the pages we reviewed.
Capabilities. RUN covers payroll, tax filing, contractor payments, recruiting through ZipRecruiter, onboarding and HR HelpDesk support. ADP TotalSource adds what a PEO carries: benefits administration, workers' compensation and HR compliance.
Integrations. RUN exports to QuickBooks, Xero, Wave and Creative Solutions and connects to Clover. ADP TotalSource documents fewer connections on the pages we reviewed.
Fit and support. ADP TotalSource assigns a dedicated HR business partner and serves small and midsize businesses. RUN offers 24/7 payroll support by phone or chat, and HR HelpDesk on its Complete and HR Pro packages.
Security. Neither names a security certification on the pages we reviewed.
