What is a PEO?

Running a business means balancing long-term vision with the daily realities of managing people, processes, and compliance. For many small and mid-sized businesses (SMBs), HR responsibilities can expand faster than internal resources can handle. That’s where a Professional Employer Organization (PEO) can make all the difference.

In this guide, we’ll break down:

• What a PEO actually does and how the co-employment model works
• The services PEOs provide across HR, payroll, benefits, and safety
• How PEOs reduce risk, streamline operations, and support growth
• Ways PEOs help strengthen employee relations
• Which industries commonly partner with PEOs
• How to choose the right PEO for your business

Let’s start by defining what a PEO does and how it supports business owners.

What Does a PEO Do for Small and Mid-Sized Businesses?

A Professional Employer Organization (PEO) supports small and mid-sized businesses by taking on many of the HR and administrative functions that can strain time, resources, and expertise. 

Under a structure known as co-employment, business owners maintain full authority over daily operations and workforce management, while the PEO shares certain employer-related administrative responsibilities such as payroll tax filings and benefits administration.

In practical terms, business owners continue to direct their teams, and the PEO provides support with HR functions that tend to slow growth or create risk when not properly guided.

What Services Does a PEO Provide?

A PEO supports small and mid-sized businesses by assisting with core HR, payroll, and administrative responsibilities that typically require significant time and expertise. These services help business owners reduce risk, streamline operations, and maintain focus on growth.

Common services a PEO offers include:

• Human Resources: Guidance on HR operations, documentation, and labor compliance requirements to help businesses manage workforce needs more effectively.
  
  
• Payroll Processing: Administration of payroll, wage calculations, and payroll-related tax filings to support accuracy and help reduce the risk of costly errors.
  
  
• Workers’ Compensation: Access to workers’ compensation coverage and support with claims management, safety practices, and injury-prevention strategies.
  
  
• Benefits Administration (including retirement options such as 401(k) plans): Management of employee benefits and support with enrollment, renewals, and employee questions.
  
  
• Risk Management: Assistance with safety programs, policies, and navigating regulatory requirements to help reduce exposure to fines or disputes.
  
  
• Staffing: Support with sourcing talent, implementing hiring processes, onboarding, and developing training programs that strengthen employee performance and retention.
  
  
• Technology Solutions: HRIS technology including an Applicant Tracking System (ATS), payroll platforms, learning management systems, and timekeeping solutions that streamline workforce management.

PEOs like BBSI also provide access to a dedicated service team. For BBSI, this includes a business strategist, HR consultant, safety and risk consultant, payroll specialist, benefits consultant, and staffing professional. Together, this team can support business owners across daily operations.

How Do PEOs Help Businesses Save Money? 

A PEO can reduce costs for small and mid-sized businesses by handling time-consuming administrative tasks and helping limit exposure to employment-related risks. By shifting these responsibilities to a specialized partner, business owners can redirect internal resources toward growth.

Key ways a PEO helps lower operating costs include:

Reduced HR Overhead

PEOs manage HR tasks such as onboarding, documentation, employee relations, and policy development. This can limit the need for additional HR staff and reduce expenses tied to hiring, training, and retaining internal HR personnel.

Support With Labor Compliance

With expertise in employment regulations, PEOs help businesses navigate complex HR requirements to reduce their risk of costly fines, disputes, or compliance-related errors.

More Efficient Payroll Management

A PEO administers payroll processing, wage calculations, and payroll tax filings. This support helps minimize payroll errors that could result in penalties or reprocessing costs.

Operational Efficiency Through Delegation

By removing repetitive administrative tasks from the workload, business owners and managers gain more capacity to focus on projects that directly impact revenue and growth.

Why Do SMBs Get More Out of Their Benefits Packages With a PEO?

Small and mid-sized businesses often struggle to administer and manage employee benefits on their own. A PEO supports these businesses by helping them navigate benefits selection, administration, and employee communication, making the overall benefits experience smoother and more competitive.

Here are a few ways a PEO strengthens an SMB’s benefits program:

Simplified Benefits Administration

A PEO manages key administrative tasks, including enrollment, renewals, required documentation, and routine employee inquiries. This support frees business owners from complex processes that typically demand significant time and HR expertise.

Access to a Broad Range of Benefit Options

PEOs can connect SMBs with established benefits offerings without requiring businesses to build these programs from scratch. Programs for health insurance, dental and vision plans, and retirement options like 401(k) plans are all available at competitive pricing through the PEO’s sponsored plans or programs selected by the employer.

Support for Long-Term Employee Financial Planning

Many PEOs assist with retirement plan administration, helping businesses offer employees access to savings tools and long-term financial planning resources that can strengthen retention and satisfaction.

User-Friendly Benefits Platforms

PEOs like BBSI offer technology solutions that streamline the benefits experience. Employees can review plan information, manage enrollments, and access documents through secure online portals available on desktop or mobile devices.

What Risk Management Challenges Can a PEO Help SMBs Navigate?

Small and mid-sized businesses face ongoing risk related to employment regulations, workplace disputes, and workforce management. A PEO supports business owners by offering guidance, resources, and administrative expertise that help reduce exposure to common HR-related risks.

Below are three challenges many SMBs encounter and how a PEO can assist.

Risk 1: Keeping Up with Regulatory Changes

Employment laws are in a constant state of flux. Keeping abreast of these changes can be a full-time job, and there isn’t any room for error. A misstep here can lead to penalties, fines, and even long-term reputational damage.

How a PEO Helps:  A PEO will specialize in adapting to regulatory shifts and keeping watch for changes so you are up-to-date with new laws. They’ll keep you out of the legal jungle by helping you keep your business compliant.

Risk 2: Employee Disputes and Potential Legal Exposure

Employee complaints or disputes, whether related to discipline, termination, or workplace policies, can drain resources and create operational and reputational challenges.

How a PEO Helps:  Many PEOs provide HR guidance on documentation, employee relations, and best practices. This support helps businesses respond to disputes more effectively and reduces the likelihood of costly escalation.

Risk 3: High Turnover and Hiring-Related Challenges

Turnover increases costs, disrupts productivity, and can heighten the risk of employment-related claims if processes are inconsistent or poorly documented.

How a PEO Helps: PEOs assist with hiring, onboarding, training, and HR documentation. By supporting consistent processes and offering best-practice guidance, they help businesses strengthen retention and reduce exposure to issues such as wrongful termination claims.

How Do PEOs Free Business Leaders to Focus on Higher-Value Work?

Business leaders often lose time to HR tasks, documentation requirements, and administrative responsibilities. A PEO helps business owners reduce that burden by supporting essential workforce functions, allowing leadership teams to concentrate on strategy, operations, and growth.

Here are key ways a PEO helps leaders reclaim their time:

Effortless HR Operations

HR paperwork and day-to-day administrative tasks can pull leaders away from critical decision-making.

How a PEO Helps: A PEO helps business owners manage routine HR processes such as onboarding, benefits administration, employee documentation, and policy updates. This support helps leaders stay focused on priorities that move the business forward.

Simplified Risk Management

Employment-related risks, from documentation issues to safety concerns, require ongoing attention and can consume leadership bandwidth.

How a PEO Helps: PEOs guide risk management practices, including the performance of onsite hazard analysis, employee safety education, and the creation of incident response plans. This assistance helps businesses navigate potential issues more effectively and reduces the amount of time leaders spend addressing risk.

Improved Efficiency and Productivity

Administrative responsibilities can slow down even experienced leaders, limiting their ability to plan, innovate, or manage teams effectively.

How a PEO Helps: By delegating time-consuming or repetitive tasks to a PEO, businesses free their leaders to use their skills where they deliver the greatest value: strengthening operations, improving processes, and driving long-term growth.

How Can a PEO Support Business Growth and Scalability?

As a business expands, HR processes, compliance responsibilities, and workforce management needs often grow more complex. A PEO helps business owners scale more efficiently by providing structure, resources, and administrative support that adapt to changing demands.

Here are several ways a PEO supports scalable growth:

1. Workforce Adjustments During Growth or Seasonal Shifts: PEOs assist with recruiting, onboarding, offboarding, documentation, and related HR tasks, helping businesses adjust workforce size as needs change.
   
   
2. Scalable HR Processes for Expansion: With experience supporting growing companies, PEOs help build HR processes that can support new locations, additional employees, or expanding teams while offering guidance on regulatory considerations in new markets.
   
   
3. Support Through Market Changes: When conditions shift unexpectedly, a PEO can help businesses adapt by offering HR guidance, workforce planning support, and administrative consistency during periods of uncertainty.
   
   
4. Assistance During Major Organizational Transitions: Events like mergers, acquisitions, or restructuring require careful alignment of HR practices. PEOs support these transitions by helping standardize policies, documentation, and onboarding approaches to maintain continuity.

How Can a PEO Support Better Employee Relations?

Employee relations can become challenging as a company grows, especially when business owners must balance communication, performance management, and workplace concerns. A PEO provides structured guidance and tools that help businesses foster stronger relationships with their employees.

Key areas where a PEO offers support include:

Conflict Resolution

Workplace conflict is inevitable, and responding effectively requires clear documentation and neutral guidance.

How a PEO Helps: A PEO can serve as an objective third party to help address disputes, provide HR best practices, and support fair, consistent processes that protect both the business and its employees.

Feedback and Coaching

Regular, constructive feedback is essential for employee development and performance.

How a PEO Helps: PEOs help create feedback systems, performance review structures, and coaching practices that encourage clarity, accountability, and long-term employee growth.

Employee Engagement

Understanding employee sentiment helps businesses build stronger cultures and retain talent.

How a PEO Helps: A PEO can facilitate employee surveys, help analyze results, and provide recommendations to address concerning trends. This support enables business owners to respond proactively and strengthen workplace engagement.
