How ADP Comprehensive Services plugs into your business

ADP Comprehensive Services partners with your organization to support some or all areas of HR and payroll. The level of support is tailored to your needs, delivered through designated service teams working within ADP Workforce Now®, our trusted HCM platform. Depending on your organization’s requirements, support can span HR, payroll processing, benefits administration, talent management, compliance guidance and more.

Companies with an internal HR person or department

ADP Comprehensive Services is a partner rather than a replacement for your HR department. The service provides ongoing support and guidance to help you more effectively manage HR, talent management, payroll and benefits.

As such, your current HR and payroll staff can collaborate with their designated ADP service team to rethink certain critical processes. They can also outsource highly manual tasks to help support compliance and avoid the extra costs associated with increasing headcounts.

Companies without an internal HR person or department

If your organization is growing fast or has experienced significant turnover, ADP Comprehensive Services can quickly deliver expertise to help you tackle critical people processes. The solution serves as a comprehensive and scalable resource for all things related to HR, such as compliance, payroll administration, talent management, benefits administration and much more.

Where ADP Comprehensive Services fits among HR outsourcing models

Companies exploring HR outsourcing encounter a range of service models. Of these, ADP Comprehensive Services draws from the best elements of HRO, BPO and managed services to deliver a scalable, full-service partnership.

Here’s how the main models compare:

• Tech-only or software-as-a-service (SaaS): HR SaaS is cloud-based software that simplifies and automates HR tasks, such as payroll, onboarding and time tracking. It typically takes the form of an HCM system.
• Administrative services offering (ASO): This platform can vary greatly, from a technology solution with a help desk to a full or partial HR administrative service.
• HRO: A third-party manages HR and relevant administrative services on behalf of its clients. Options range from basic ASO to a partnership with a professional employer organization (PEO).
• BPO: A company hires an external provider to handle some or all of its HR functions, like payroll, recruitment, benefits and compliance. Delegating these tasks to an expert helps improve efficiency.
• Managed services: A vendor handles all or most HR duties on behalf of a business so it can focus on strategic growth. The organization maintains oversight and control of the outsourced functions, which can include payroll and taxes, talent, and benefits.
• PEO: This full-service solution helps manage HR, payroll, benefits and compliance for employers. It’s a co-employment relationship, which means that both parties share compliance responsibilities. PEOs also deliver economies of scale for employee benefits and workers’ compensation.

When is ADP Comprehensive Services the right fit?

ADP Comprehensive Services is particularly well-suited for businesses experiencing change. Here are common signs that your organization might be ready:

• Your company is growing rapidly: Companies that are expanding quickly need to maintain their momentum. They can’t afford to get sidetracked with day-to-day tasks. A managed HR and payroll services partner can provide the tools and insights they need to support a successful growth strategy.
• Your company is going through a merger and/or acquisition: It’s not uncommon for mergers and acquisitions to cause HR complexities that impact operations. Managed services providers can help reduce risk during these transactions by integrating and simplifying HR, payroll and benefits administration processes.
• Your HR or payroll department is understaffed or overstaffed: An understaffed HR team can lead to burnout and costly compliance errors, while an overstaffed team can drain resources and diminish efficiency. Both scenarios hinder a company’s ability to manage its workforce effectively. The solution is a managed services provider that takes on essential administrative tasks, thereby helping to alleviate pressure and increase productivity.
• Your internal HR or payroll processes need updating: As companies evolve, they sometimes outgrow their HR and payroll processes, which may increase compliance risk and employee dissatisfaction. Scalability can be achieved in such situations by partnering with a managed services provider for best practices and administrative support.
• Your company is going through a divestiture: Divestitures often occur when companies try to adapt to changing market conditions or enhance operational efficiency after slimming down. A managed services provider can provide strategic insights during these challenging transitions to help improve their likelihood of success.
• Your company is transitioning from a PEO: As companies expand from a small or medium-sized business to a large employer, they may decide they don’t need a full-service PEO. They can naturally transition to managed services for assistance with complex HR, payroll and benefits while they adjust their in-house HR staffing model or processes.
