FAQ: HR outsourcing companies

Here are answers to common questions about HR outsourcing companies.

What are HR outsourcing companies?

HR outsourcing companies are third party vendors who handle human resource responsibilities for outside organizations. These servicers often handle jobs like recruiting and onboarding, payroll, benefits administration, and performance management. Contracting with an HR outsourcing company is often more cost-effective than staffing a full HR department, especially for smaller and midsize businesses. These providers can also help companies keep organized and compliant with numerous HR regulations, and offer expertise in specialized areas such as health insurance, labor rights, or international regulations.

How do HR outsourcing services work?

HR outsourcing companies serve as third party vendors that manage agreed-upon HR functions. The employer and the HRO enter into a deal determining a monthly fee for certain services. Then, the company sends employee information or employees self-report through an online portal, and the HRO coordinates human resources for the company. Many of these tasks are facilitated through the use of HR software, however outsourcing companies also tend to employ HR professionals on-staff to answer questions and help guide clients.

How much does HR outsourcing cost?

The cost of HR outsourcing companies varies based on the services provided and the number of employees involved. Services can range from a couple hundred to a few thousand dollars a month, depending on the scope of the tasks. For smaller businesses, these fees are often less expensive than the costs of hiring, training, and retaining an HR director or department.

Another budget alternative to hiring in-house HR professionals is using HR software to automate basic human resources functions. In fact, many HR outsourcing companies use human resource technology to automate tasks and provide more cost-effective services to clients.

What should you consider when deciding whether to outsource HR?

When deciding whether to outsource HR, first compare the costs of traditional HR employees vs a third party vendor. Think about the amount of team members that will be involved with the system, and also consider plans to scale or grow the company. An in-house HR provider may not be able to keep pace with rapid growth. The fit of HR outsourcing also depends on how much control employers want to have over administrative functions and company culture. Leaders should factor in the long term goals of the company, decide which HR functions are most important, and find a servicer that is willing to work to build a package that caters to company needs.

What is the difference between PEO and HRO?

PEO, or professional employer organizations and HRO, or human resources outsourcing companies, tend to facilitate similar tasks. The main difference between the two types of servicers is the level of employer involvement. HROs tend to be more hands-on and tailored to organizations, and leaders have more control over the administration of services. Meanwhile, PEO’s tend to take over HR functions and handle the tasks without much employer input.
