A PEO, or professional employer organization, helps businesses handle payroll, benefits, workers’ compensation, HR support, and other employment admin through a co-employment agreement.
You still run the business and manage your employees. The PEO takes on the responsibilities listed in your agreement, reducing the HR admin your team has to handle itself.
What does PEO mean?
PEO stands for professional employer organization. It is an outside HR partner that shares certain employer responsibilities with your business.
The arrangement is called co-employment. Your company and the PEO both have a role in the employment relationship, with the exact split set out in your PEO agreement.
According to NAPEO’s September 2026 industry data, more than 233,000 U.S. client businesses use PEOs, covering 5.4 million worksite employees.
How does a PEO work?
A PEO works by splitting specific employer responsibilities between your business and the PEO. The agreement sets that split, and each side keeps handling its part.
You enter a co-employment agreement
The agreement lists the services the PEO will handle and the responsibilities your company keeps. It also covers commercial terms such as pricing and how the relationship can end.
The PEO handles the agreed HR and employment admin
Depending on your package, that can include payroll, benefits administration, workers’ comp, HR support, and compliance-related tasks.
You keep running the business and managing employees
Your managers still supervise employees, assign work, set expectations, make staffing decisions, and run day-to-day operations.
The setup process involves moving employee, payroll, benefits, and other data into the PEO’s systems. Our PEO implementation guide covers that transition in detail.
What services do PEOs provide?
PEO packages differ, but most providers focus on a similar group of HR and employment tasks.
Payroll
A PEO can process payroll, calculate deductions, pay employees, and handle payroll tax filings and payments covered by the agreement. Our PEO payroll services guide explains the payroll workflow in detail.
Employee benefits
Many PEOs provide access to health insurance and other benefits, then handle enrollment, deductions, and employee changes. Available plans depend on the provider, location, and employer. For deeper coverage, see our PEO health insurance guide and PEO benefits administration guide.
Workers’ compensation
PEOs often provide or arrange workers’ comp coverage and help with claims and workplace risk programs. The details can vary by state and provider. Our PEO workers’ compensation guide explains the coverage structures and responsibility split.
HR support
Depending on the PEO, you may get help with employee handbooks, onboarding, employee relations, policies, training, and other HR questions.
Compliance support
A PEO can help with employment paperwork, payroll tax requirements, and other HR compliance tasks included in your service package. Using a PEO does not remove every legal responsibility from your business, so you still need to know what remains yours.
What does co-employment mean in plain English?
Co-employment means your business and the PEO divide certain employer responsibilities under a service agreement. Your PEO agreement spells out who handles what.
For example, the PEO may run payroll and administer benefits while your company continues to supervise employees, set pay, assign work, and make business decisions.
One important point: calling the relationship “co-employment” does not automatically make the PEO the legal employer for every purpose. Federal tax rules, state PEO laws, workers’ compensation rules, and the contract can treat particular responsibilities differently. For federal employment taxes, using a PEO doesn’t automatically remove your company’s obligations. Under a qualifying agreement with an IRS-certified PEO (CPEO), the CPEO generally takes responsibility for employment taxes on wages it pays to covered worksite employees.
What a PEO does not change
Using a PEO does not mean you hand over the business or your workforce. You still decide who to hire, what people are paid, how work is scheduled, how employees perform their jobs, and whether someone is promoted, disciplined, or terminated. The PEO may also have a role in hiring, discipline, or termination, depending on your agreement and state law.
What does your business still handle?
A PEO can take a large amount of HR admin off your team, but it usually does not run your workforce for you. Your business generally keeps control of:
- Day-to-day employee supervision
- Job duties and work assignments
- Hiring, promotion, discipline, and termination decisions
- Pay decisions and staffing levels
- Shift scheduling and workforce planning
- Performance expectations
- Business strategy, customers, products, and services
This matters especially for hourly and deskless teams. Even if a PEO runs payroll, your managers still need to schedule shifts, track working time, manage PTO, communicate with employees, and send accurate hours into payroll. Our PEO responsibilities guide explains the broader responsibility split.
For hourly and deskless teams, Connecteam can cover the day-to-day workforce management layer alongside a PEO. Connecteam is an all-in-one employee management app for scheduling, time tracking, PTO, communication, and payroll-ready timesheets. The PEO can continue handling the HR and employment services in your agreement.
What can a PEO relationship look like in practice?
Imagine a 40-person field service company that has outgrown the owner’s spreadsheet-based HR process. The company chooses a PEO to run payroll, administer benefits, support workers’ comp, and give the manager access to HR help.
The company’s managers still build the weekly schedule, approve time off, track hours, manage jobs, and deal with employee performance. At the end of the pay period, approved time data is sent into the payroll process the PEO manages.
The PEO can take over a large part of employment administration, while the business still needs tools and processes for the work employees do every day.
What changes for employees when you join a PEO?
Employees normally keep doing the same jobs for the same business and managers. The biggest changes are usually administrative.
- Pay stubs or tax documents may come through the PEO.
- Benefits enrollment may move to the PEO’s system.
- Employees may contact the PEO for some HR or benefits questions.
- Workers’ comp, leave, or other HR processes may change.
Clear communication during onboarding helps employees understand which company or system to use for each type of question.
How is a PEO different from similar services?
Several services handle parts of HR or employment, so the names can get confusing. The main differences are:
PEO vs payroll provider
A payroll provider mainly processes payroll and payroll taxes. A PEO usually offers payroll plus broader HR services, benefits, workers’ comp, and a co-employment relationship.
PEO vs EOR
An employer of record (EOR) employs workers on a company’s behalf, often when the company does not have its own local employing entity. A PEO works with a business that already employs its workforce and uses co-employment to share certain responsibilities.
PEO vs ASO
An administrative services organization (ASO) can handle outsourced HR tasks without the co-employment model used by PEOs.
PEO vs staffing agency
A staffing agency supplies workers to a client. A PEO generally works with the employees the client business already has.
Who is a PEO a good fit for?
PEOs commonly work with small and midsize businesses that want more HR support without building a large internal HR operation.
A PEO may be worth considering if payroll and benefits are becoming difficult to manage, your business is expanding into more states, you want access to broader employee benefits, or your team needs more HR support than you can provide in-house.
A PEO may be more service than you need if you only want basic payroll processing or prefer to keep all HR functions inside your company. Our guide to deciding whether a PEO is right for your business goes deeper into those trade-offs.
What should you check before choosing a PEO?
At this stage, focus on three basics: whether the PEO covers the services you need, what your business will still own, and whether its technology and support fit the way your team works. When you are ready to compare providers in detail, use our guide to choosing a PEO, which covers evaluation criteria, questions, technology, support, and due diligence. For example, ask who handles payroll errors, how approved employee hours move into payroll, and who is responsible if something goes wrong.
Does a PEO replace your HR team?
Not always. A small business with no HR department may rely heavily on the PEO. A company with an internal HR team can use a PEO for selected areas such as payroll, benefits, workers’ comp, or HR support.
Someone inside your business still needs to manage employees, make decisions, keep information accurate, and manage the relationship with the PEO.
How much does a PEO cost?
PEO pricing usually depends on your employee count, payroll, benefits, workers’ comp, and the services you choose. Providers may charge a per-employee fee, a percentage of payroll, or a combination of service and insurance-related costs.
Quotes can be difficult to compare because providers package services differently. Our PEO cost and pricing guide explains the common pricing models and the fees to look for.
Frequently asked questions about PEOs
There is not one universal answer for every legal purpose. In a typical PEO relationship, your company continues to employ and manage its workforce while the PEO takes on specified employer responsibilities under the service agreement. The label “co-employer” does not by itself determine employer status under every federal or state law. For example, IRS rules distinguish ordinary third-party payroll arrangements from certified PEO arrangements.
Usually, no. A PEO normally works with the employees your business already has. It does not supply workers the way a staffing agency does.
Some PEOs offer these tools or integrations, but daily scheduling and timekeeping often stay with the client business. Check what your provider includes and how employee hours move into payroll.
A certified professional employer organization (CPEO) is a PEO that has completed the IRS certification program and meets its ongoing requirements. Certification is voluntary. Our CPEO guide explains when that status matters and how to verify it.
The bottom line on PEOs
A PEO can take payroll, benefits, workers’ comp, HR support, and other employment admin off your plate while you keep running your business and managing your people.
Before choosing one, focus on the responsibility split. Make sure you understand exactly what the PEO will handle, what remains with your company, what the service will cost, and how the PEO fits with the systems you already use.
