If you don’t have an HR department to manage your human resources processes, there’s a good chance you may need external support in the form of an HR outsourcing (HRO) service. An HRO can take on virtually any HR process to help your business stay compliant and boost efficiency

There are many HROs out there, but not all will have the features and flexibility your company needs. To help you identify the right HRO provider for your business, I’ve researched numerous options, spending hours evaluating their upsides, features and challenges. I’ve identified five HRO platforms that may be excellent outsourcing partner options for your business. 

What is an HR outsourcing (HRO) service?

An HR outsourcing service is a third-party organization that handles one or more HR functions for a business. HROs can accommodate the following tasks and more: 

  • Recruitment
  • Benefits administration
  • Payroll processing
  • Tax administration
  • HR policy creation
  • Employee training and development
  • Compliance assistance
  • Administrative HR functions
  • HR audits on organizations 
  • Ongoing HR support and guidance 

An HRO service is similar to a professional employer organization (PEO). However, PEOs use a co-employment model, while HRO services act as an outsourced HR department that provides specific HR functions without sharing legal responsibility for employees.

Our Review for ADP HRO

Chevron

ADP stands out as a top HR outsourcing solution, particularly in the area of benefits administration. Known for its ability to cater to businesses of all sizes, ADP provides a wide range of HR services. However, I found that its benefits administration capabilities truly shine.

The platform gives small- and mid-size businesses access to comprehensive, affordable benefits packages that rival those of much larger companies, helping them attract and retain top talent. Additionally, ADP’s user-friendly interface simplifies the benefits enrollment process, making it easy for employees to manage their benefits with minimal confusion.

HRO service costs

An HR outsourcing service costs between $50 and $1,500 per employee per month. While this may seem like a substantial range, monthly costs depend significantly on the features you need and how many employees you have. Some HROs charge a fixed per-employee-per-month rate, while others base monthly charges on a percentage of your employees’ salaries. 

Here are some HRO pricing factors to keep in mind: 

  • Minimum requirements: Many HROs require businesses to have five to 10 employees in order to provide eligible services. If you have a smaller team, checking a potential provider’s minimum requirements is crucial.  
  • Bundled vs. a la carte services: Some HROs require you to bundle specific HR features, while others allow for a la carte service customization.
  • Additional fees: Employee benefits are always an additional cost, whether you pay for bundled or a la carte services.
  • Billing: HR outsourcing providers typically offer monthly and annual billing, although annual billing is usually less expensive.

How to choose an HRO

An HR outsourcing company can significantly improve organizational efficiency. However, finding the right HRO for your unique business needs is critical. Take the following steps to ensure you partner with the best HRO for your organization. 

  • Determine what HR services must be outsourced. Take inventory of your current HR processes and identify any gaps or inefficiencies. This exercise will help you determine what HR processes are going well and what should be outsourced. If you plan to expand operations, you must also consider your future HR gaps and needs.
  • Establish your HR priorities. Which HR services and features are critical, and which would simply be nice to have? For example, are your employees tech-savvy, or will you need a basic, intuitive platform that’s easy to implement? Is a specific price point a dealbreaker, or do you have a flexible budget? Only you will know what’s most important to your business, but defining your priorities before beginning your search is crucial. 
  • Gather a list of potential HR vendors. Research potential HRO vendors, like the ones listed on this page, to get a feel for your options. Each vendor has unique strengths and weaknesses, so you should be able to quickly tell which ones are valid contenders and which ones aren’t a good fit.
    Conduct demos and intro calls. Once you’ve chosen a shortlist of top vendors, schedule demos and intro calls with them. During these calls, you should expect to get a firsthand look at the software and ask your questions. Inquire about pricing, contracts, service plans, add-on options, implementation, customer support and additional fees. 
  • Compare and choose an HRO. The last step in this process is to compare your top choices based on the information you gathered in your research and demo calls. Compare factors like available HR services, implementation, pricing and contracts, tech usability, scalability and ongoing support. A clear winner should emerge.

Whether you’re choosing an HRO for the first time or looking to upgrade your current service, it’s critical to consult with key stakeholders, such as your HR professionals, about your decision.

Methodology

To find the best human resources outsourcing services available, I started by researching and analyzing dozens of potential HRO solutions. I discovered the key players through industry experience and market research, and then I did a deep dive into each HRO provider. I looked at company websites, competitor comparison pages, the Better Business Bureau (BBB), accreditation sites and customer reviews. 

Through this research, I was able to examine and compare pricing, contract requirements, HR services and limitations, payroll processing capabilities, benefits administration, accreditations, compliance and customer support. I also participated in guided tours and product demos to gain firsthand experience with each platform’s functionality and ease of use.
