HR Outsourcing

HR outsourcing (HRO) is when a business hires an external provider to handle one or more human resources tasks instead of performing them itself. These services may include payroll administration, benefits administration, recruiting support, HR policies and compliance support. Companies use HR outsourcing to get specialized expertise, to make HR more cost-effective and to scale HR operations as they grow. HR outsourcing can be project-based (like updating compensation programs) or ongoing (like payroll processing), depending on business needs. 

As organizations grow, HR operations require greater coordination and effort. HR outsourcing allows leaders to delegate specific administrative duties while focusing on business goals. 

What Is HR Outsourcing (HRO)?

HR outsourcing, also called human resources outsourcing (HRO) or outsourced HR, involves working with an external provider for selected HR responsibilities. Companies may outsource a single HR function, such as benefits administration, or several functions depending on their operational needs, internal resources and business goals. 

Outsourcing HR is not an all-or-nothing approach. Many organizations continue managing employee relations, hiring decisions and company culture internally while receiving outside assistance for administrative or specialized HR work. 

What HR Functions Can You Outsource?

Businesses can outsource a variety of HR responsibilities based on the level of support they need, including core administrative functions, people programs, benefits administration and specialized support. 

Core administrative functions

These routine administrative tasks are among the most commonly outsourced because they involve ongoing documentation and repetitive processes. 

  • Payroll processing support
  • Payroll tax administration support
  • HR recordkeeping
  • Employee onboarding administration

People programs

Businesses can outsource selected talent-management activities while continuing to supervise employees internally. 

  • Recruiting coordination
  • Learning and development support
  • Performance cycle support

Benefits administration

Businesses often outsource benefits administration to reduce administrative workloads and give employees better resources for navigating enrollment and leave-related processes. 

  • Benefits enrollment
  • Leave management
  • Employee communications
  • Eligibility tracking
  • Coverage recordkeeping

Specialized support

Organizations frequently outsource complex HR initiatives when they need knowledge or experience that isn't available internally. This includes areas like: 

  • Compensation benchmarking and program design
  • Performance management design
  • Leadership coaching
  • Pay transparency preparation
  • HR consulting

How Does HR Outsourcing Work in Practice?

The working relationship between a business and its HR outsourcing provider will depend on the services, the provider and many other factors. However, there are common, basic arrangements. 

  • Project-based support. Businesses may hire an HR provider for a specific initiative, such as updating an employee handbook, revising workplace policies, or preparing pay transparency job-posting processes.
  • Ongoing support. Some organizations receive recurring assistance with administrative workflows, reporting, payroll administration, benefits administration, or other routine HR functions.
  • Business responsibilities. Even when HR functions are outsourced, employers typically retain responsibility for hiring decisions, employee performance management, workplace culture, policy approvals and other key employment decisions.

Types of HR outsourcing

Business that turn to outsourcing have a wide range of HR models to consider, including: 

  • Professional employer organization (PEO). A PEO provides a comprehensive range of HR services through a co-employment arrangement, meaning certain employer responsibilities are shared between the business and the PEO. 
  • Administrative employer organization (AEO). An AEO provides administrative HR services, such as payroll and/or benefits support, while the business remains the sole employer and retains full responsibility for its employees.
  • Human resources outsourcing (HRO). HRO typically involves outsourcing specific HR functions such as payroll processing, benefits administration, recruitment and training tools. Companies may choose to outsource one or more HR functions based on their needs.
  • Business process outsourcing (BPO). Business process outsourcing is the practice of contracting specific business operations and responsibilities to external service providers. BPO involves engaging with specialized third-party companies that can perform certain tasks more efficiently or cost-effectively. These business functions might include: customer service, accounting, data entry and technical support.
  • HRMS support. Some businesses outsource their HR software needs to a human resources management system (HRMS). The provider supplies and supports a central system for documentation, employee data management, reporting, system administration, employee self-service (ESS) portal and other needs. An HRMS might also come as part of a package with a PEO, ASO or other outsourcing solution.

Why Do Small and Medium-Size Businesses Outsource HR?

Businesses outsource HR for different reasons depending on their size and available resources. Many small and medium-sized businesses turn to HR outsourcing to: 

  • Reduce administrative work. Routine HR support gives owners and managers more time to focus on running the business, supporting growth and serving employees.
  • Access specialized expertise. Businesses gain access to experienced HR professionals when specialized knowledge or guidance is needed.
  • Add support during busy periods. Additional HR resources help businesses manage periods of increased activity, such as rapid hiring, benefits enrollment, or year-end performance reviews.
  • Improve consistency. Working with an external provider can help standardize HR processes and documentation across the organization.
  • Support a positive employee environment. Well-managed HR processes can improve the employee experience through timely communication, organized onboarding and consistent HR support. Outsourcing with a PEO also can give small and medium-sized businesses access to big-company benefits that they could not attain otherwise. And the employee self-service (ESS) portals associated with human resources information systems (HRIS) make it easier for employees to access HR functions and information.

How Much Does HR Outsourcing Cost?

HR outsourcing costs vary because every business has different staffing needs and service requirements. Comparing pricing structures, contract terms and services can help businesses determine which arrangement best fits their needs. Here are some key factors to consider: 

  • Number of employees. Larger workforces typically require more administrative support, which may increase overall service costs.
  • Business locations or operating states. Businesses operating in multiple states or locations may need additional HR resources to manage different employment requirements and administrative processes.
  • Services included. The total cost often depends on the scope of HR services a business outsources, whether that's a few administrative functions or more comprehensive ongoing support. 
  • Implementation complexity. Transitioning employee records, payroll information, or existing HR processes may require additional setup time and resources.
  • Contract length. Pricing may vary depending on whether services are provided through a short-term agreement or a longer-term contract.
  • Optional consulting or add-on services. Specialized support, such as leadership coaching, compensation planning, or workplace investigations, may increase the overall cost beyond standard HR services.

HR outsourcing companies offer different pricing models, including per employee per month, a percentage of employees’ pre-tax monthly earnings, per-service pricing and per-product pricing. 

How Do You Choose an HR Outsourcing Provider?

When comparing providers, consider the following questions: 

  • Which HR responsibilities consume the most time?
  • Which services are required versus optional?
  • Can the provider support multi-state operations, if needed?
  • How is employee information protected?
  • What response times or service expectations are provided?
  • Can the provider demonstrate relevant experience, client references, appropriate insurance coverage and a communication style that fits your organization?

Reviewing these factors helps businesses compare providers based on their operational needs rather than price alone. 

FAQ

Is HR outsourcing the same as hiring an HR consultant?

No. HR consultants are generally hired to provide strategic guidance or complete specific projects, whereas HR outsourcing involves delegating HR functions to an external provider. Depending on the business's needs, those services may be project-based, ongoing, or a combination of both. 

Can you outsource only payroll or benefits administration?

Yes. Many businesses outsource only payroll administration, benefits administration, or another specific HR function while continuing to manage the rest of their HR responsibilities internally. However, businesses often turn to a PEO for comprehensive HR outsourcing service. 

Does outsourcing HR mean the employer is no longer responsible for compliance?

No. Although an HR outsourcing provider may offer guidance and administrative assistance, employers generally remain responsible for meeting applicable employment laws and workplace obligations. 

What are common risks of HR outsourcing, and how do you reduce them?

Common challenges include communication gaps, unclear service expectations and data security concerns. Clearly defining responsibilities, reviewing contracts carefully and choosing an experienced provider can help reduce these risks.
