How much does ADP TotalSource cost?

Contact ADP TotalSource to get a custom quote for your business.

Here's how current users are saying TotalSource has impacted their bottom line.

“With ADP TotalSource our top line and bottom line have been enhanced. The time savings we get are repurposed to drive sales. The cost of retaining TotalSource is less than sourcing all the solutions individually and then hiring a manager to oversee it.”         –CEO, Professional Services

“Our ADP representatives are full of knowledge and will get us answers to questions quickly. And ADP TotalSource is saving us a lot of money.”        –VP of HR and Administration, Manufacturer

Is ADP TotalSource a certified PEO?

Yes, ADP TotalSource has met all the rigorous background, financial and reporting requirements set by the IRS. This certification ensures financial protections and tax benefits to TotalSource clients that users of non-certified PEOs do not necessarily receive. ADP TotalSource helps ensure your federal employment taxes are paid.

Which platforms does ADP TotalSource integrate with?

TotalSource has pre-built, secure integrations and data connectors with over 300 business software applications and leading payroll, HR and financial systems. ADP can also create a custom API (or integration) if you need data integration with a system we don’t already integrate with.

How easy is it to implement ADP TotalSource?

We make it easy by working with you every step of the way. First, you’ll assign a team member from your end to partner directly with us. We’ll take care of all the heavy lifting, but we want to make sure you’re staying close throughout the process, overseeing setup and system tests. On average, this amounts to a time commitment of about one hour per day for the first few weeks.

From there, you’ll meet your dedicated ADP Human Resources Business Partner, who will take you through the different ways we can help you manage your workforce across benefits, compliance, training, hiring, retention, and more. You'll also learn about the experts and specialists across many disciplines working behind the scenes for you. You can expect to be up and running with TotalSource in a few weeks.

  • Expert guidance for HR situations
