Drive employee engagement and satisfaction with ADP TotalSource®

Co-employment is the legal foundation of ADP TotalSource. ADP takes on certain employer responsibilities, such payroll administration, benefits administration and compliance, while you keep control over hiring, firing, pay decisions and day-to-day operations. ADP takes on your administrative HR work and offers guidance where needed, but company culture and decision-making remain firmly yours.

ADP TotalSource manages multi-state payroll, tax filings and state-specific compliance as part of its core platform, so you don't need separate systems or vendors for each state you operate in. As your business expands, ADP TotalSource scales with you, absorbing the added compliance and payroll complexity that comes with growth.

ADP TotalSource supports small and midsize businesses across a wide range of industries, including professional services, manufacturing and logistics, architecture and engineering, real estate, wholesale, nonprofits and many more. Whatever your industry, ADP TotalSource scales to fit your size, complexity and footprint. Discover how with client stories.

ADP makes it easy by working with you every step of the way. First, you'll assign a team member to partner directly with us. ADP will handle the heavy lifting, but you'll stay close throughout the process, overseeing setup and system tests. From there, you'll meet your dedicated HR business partner, who'll walk you through how we support your workforce across benefits, compliance, training, hiring and retention. Most businesses are up and fully running within a few weeks.
