PEO vs HRO: Which Option is Right for Your Company?


When it comes to managing human resources, businesses have many different options available to them. Two of the most common are Human Resources Outsourcing (HRO) and Professional Employer Organizations (PEOs). While both options offer valuable services to businesses, it’s important to understand the differences between the two and determine which one is the best fit for your organization.

What is a HRO?

A Human Resources Outsourcing provider is a third-party organization that provides a wide range of HR services to businesses. These services can include:

  • Payroll processing
  • Benefits administration
  • Compliance management
  • Recruiting and staffing support
  • Employee relations support

One of the biggest advantages of working with an HRO is that it allows businesses to focus on their core competencies while leaving the HR functions to experts. HROs can also be more cost-effective for smaller companies that might not have the resources to hire a full HR team in-house.

However, there are some potential disadvantages to consider as well. For example, some businesses might prefer to have HR functions handled in-house to maintain greater control over the process.

In terms of industries or business types that might benefit more from using an HRO, smaller businesses in particular can often benefit from this option. HROs can also be a good fit for companies that are looking to improve their HR processes or are experiencing rapid growth.

What is a PEO?

A Professional Employer Organization is also a third-party HR service provider, but it typically offers a more comprehensive range of services. In addition to the functions provided by an HRO, a PEO can also take on legal and financial responsibilities for a business, including:

  • Employment law compliance
  • Tax compliance
  • Workers’ compensation insurance
  • Unemployment insurance

One of the key benefits of using a PEO is that it can help businesses reduce their risk exposure. By taking on some of the legal and financial responsibilities, a PEO can help protect a business from costly compliance violations or lawsuits.

However, the additional services provided by a PEO can also come at a higher cost. Businesses need to carefully consider whether the added benefits are worth the extra expense.

PEOs can be a good option for businesses in a variety of industries, particularly those that need help managing legal and financial compliance. PEOs can also be a good fit for companies that are looking to expand into new markets or grow their existing operations.

Differences Between HRO and PEO

While there is some overlap between the services provided by an HRO and PEO, there are some key differences to be aware of when making a decision. These include:

Legal Responsibilities

As noted above, PEOs take on more legal responsibilities than HROs, which can be a major benefit for businesses looking to reduce their risk exposure.

Employee Benefits

PEOs also typically offer a wider range of employee benefits than HROs. This can include health insurance, retirement plans, and other perks that can help businesses attract and retain top talent.

Risk Management

HROs can offer risk management services, but PEOs typically provide more comprehensive support in this area. This can include help with workers’ compensation claims, unemployment insurance, and other legal or financial issues that can arise.

HR Functions

Both HROs and PEOs can handle a wide range of HR functions, but PEOs typically offer more comprehensive support. This can include help with recruiting, performance management, and other key areas of HR.

Which One is Right for Your Business?

Ultimately, the decision of whether to use an HRO or PEO will depend on several factors, including the size and type of your business, your HR needs, and your budget. Here are some key factors to consider when making your decision:

  • Size of your business: Smaller businesses may be better suited to using an HRO, while larger businesses may benefit more from the added services provided by a PEO.
  • HR needs: Consider which HR functions you need help with, and whether an HRO or PEO can provide the level of support you require.
  • Legal and financial considerations: If your business has complex legal or financial needs, a PEO may be the better option.
  • Budget: PEOs typically come with a higher price tag than HROs, so it’s important to consider whether the added benefits are worth the additional cost.

To help make your decision, it can be helpful to speak with other business owners who have used HROs or PEOs, and to get recommendations from industry groups or professional associations.


In summary, both HROs and PEOs can provide valuable HR services to businesses. However, there are some key differences to be aware of when making a decision. By considering your business’s unique needs and weighing the pros and cons of each option, you can make an informed decision about which option is right for your organization. Whether you choose an HRO or PEO, outsourcing your HR functions can help streamline your operations, reduce your risk exposure, and allow you to focus on your core competencies.
