ADP TotalSource® features and benefits

Offer Fortune 500®-caliber benefits

You gain access to benefits usually available only to larger companies — including cost-effective insurance, commuter benefits, perks and discounts, and a competitive 401(k) retirement savings plan.

Expert guidance on what to offer

Each year, we’ll review your benefits plans and contribution amounts to help eliminate guesswork. We help you compare options and make an educated decision about which plans are best for you.

Employee access to answers

Employees can enroll in benefits online and have access to knowledgeable advisors to help answer benefits questions.

Accidents happen. 2.9 million non-fatal workplace injuries and illnesses were reported by private industry employees in 2015.

Protect from injuries and lawsuits

Workplace injuries. Employee issues. Regulation overload. We keep up with ongoing changes and help you plan ahead and comply.

Prevent and respond to workplace injuries

A risk and safety consultant will recommend ways to help keep employees safe and help limit your liabilities.

Protect from employee claims and lawsuits

Learn how to handle interviews, terminations, discipline and mandatory leave laws — such as those covered by the Family and Medical Leave Act (FMLA). And if a lawsuit comes your way, we'll help you through it.***

Identify and cover your compliance blind spots

Let us monitor regulatory changes so you don’t have to.

You don’t need to be the expert on everything

With a dedicated team of HR experts in your corner, we can guide you through whatever comes your way. We’ll use your data to identify trends, make recommendations and help you take action to keep your business on track.

You want to attract, retain and engage the best people, aligning their goals to your business goals. In other words, you want to go beyond managing human capital and start unleashing human potential.

We have a suite of proprietary products and services carefully curated to help enable meaningful experiences at work. Once you unlock each person’s full potential, imagine where your business could go.

Modern HR and PEO software

Your business's needs are unique and you need a solution that can adapt.

All in one — but never one size fits all

ADP TotalSource can help you cover every aspect of human capital — payroll and tax, benefits, performance, training, compensation, employee issues, compliance, time tracking and everything in between. Everything is integrated: your new-hire data flows from onboarding to everyday tasks through to retirement. You never have to enter data twice.

Top-rated app for your employees

A personalized app keeps employees’ information at their fingertips — from vacation hours to benefits plans.

ADP TotalSource is a certified professional employer organization (PEO)

PEOs (professional employer organizations) help you manage your human resources, employee benefits, regulatory compliance and payroll.

In fact, ADP TotalSource is an IRS-certified* PEO that meets the high standards set by the IRS. Your benefit? ADP TotalSource helps ensure your federal employment taxes are paid. And unlike what can happen when joining an uncertified PEO, you’ll never have to deal with double IRS taxation.

HR outsourcing for small and midsized businesses

Learn how you can avoid three common issues that bog down small and midsized businesses.

More advantages for your employees — and for you

ADP TotalSource works through a co-employment arrangement, which means we contractually share certain employer responsibilities with your company. That means you and your employees benefit from more advantages than you could ever get alone.

With ADP TotalSource, you can:

  • Provide employees access to high-quality, comprehensive benefits
  • Stay on top of employment regulations and compliance
  • Use data insights to help you manage key business implications, such as turnover
  • Provide career development and performance feedback
  • Minimize administrative HR tasks
  • Get HR support without increasing headcount
