EXPERT SUPPORT

Service delivery tailored to your payroll and HR compliance needs

ADP built its business on technology-enabled services designed for people

We understand the importance of feeling confident in the team managing your compliance work and knowing that you can reach someone directly for any issues that arise. Our model is one of visibility, transparency and dedicated, accessible service.

  • Visibility – The purpose-built ADP SmartCompliance portal lets you clearly see the work being done on your behalf.
  • Configurable alerts – A simple dashboard experience alerts you to any urgent actions required and lets you know what can wait.
  • Knowledge – Regular legislative updates, training and one-on-one guidance help ensure that you know what changes are coming and how they may impact you.
  • Directly reachable service – You will have designated service reps that are experts in each area of compliance and available by phone, secure email, or, in many cases, online chat.
  • Managed service option – If you are currently using OSV to fully manage your entire payroll and post-payroll processes, ADP can provide end-to-end managed payroll services with representatives who hold Workday Payroll certifications.2

Why ADP is the leading choice over OSV

Directly Reachable Service

Tenured service representatives you can contact directly

Being able to directly reach an expert about a critical compliance matter provides confidence that the issue is in good hands. That’s why ADP provides designated service representatives who have expertise in each area of compliance and are directly accessible by phone, secure email or, in many cases, online chat.

OSV post payroll services can require additional agreements to include a dedicated service representative. OSV also drives service requests through their help desk ticketing system.

Visibility and Transparency

Peace of mind that compliance activities are in good hands

The purpose-built ADP SmartCompliance portal combines multiple compliance processes and the data behind them into one, easy-to-use solution. The status of work being done on your behalf is easily viewable and you can drill down into employee-level detail, if needed, to be confident that work is being done and exceptions are being addressed.

OSV provides limited data in file formats that require work on your behalf to review, research and resolve. Often, these reports must be requested via a support ticket and, thus, may not be available immediately.

Best-in-Class Workday Integrations

Data integration to a purpose-built compliance platform

ADP leverages REST APIs and other modern data integration methods to directly and securely transmit the data needed for each compliance process to ADP SmartCompliance and back to Workday. These integrations make it possible for us to be flexible and agile as requirements change without any burden on the Workday system. They also allow for near real-time availability of information and help avoid errors caused by the manual handling of data.

OSV manages your post payroll process by directly accessing your system to pull data to process your payroll taxes, for example, in their own proprietary tax engine. This requires their personnel to have direct login access to your live Workday production instance to move your data.

Compliance as a Strategy

ADP was founded on and continues to focus on compliance

ADP was founded on the principle of helping reduce the employer burdens associated with regulatory requirements. It remains our focus today. From strategic planning to the talent we hire, ADP is all about compliance and the innovations needed to stay ahead of ever-increasing employer burdens, as well as the changing needs of workers.

OSV originated as a software system integrator that has more recently also begun offering some compliance services.

Breadth of Compliance Expertise

Connect Workday to a wide range of compliance services

ADP offers a wide selection of compliance services with a broad range of features. This helps you reduce burden, improve accuracy and reduce risks associated with compliance processes, such as payroll tax filing and remittance for employees and independent contractors; end-to-end management of wage garnishments; a single-vendor solution for pay distribution by direct deposit, paycard or check; monthly comprehensive management of Affordable Care Act (ACA) eligibility, affordability and reporting; unemployment claims management; automated employment and income verification; Work Opportunity Tax Credit (WOTC) screening and management; and efficient management and payment of independent contractors.

While OSV offerings address multiple compliance processes, their listed services are not as comprehensive as those of ADP.
