What is HR outsourcing?

HR outsourcing is the practice of partnering with external HR experts to handle essential responsibilities — such as payroll, benefits administration, and compliance — so businesses can focus on core operations and growth.

What is a PEO (Professional Employer Organization)?

A Professional Employer Organization (PEO) is the most comprehensive form of HR outsourcing available. Rather than handling one or two tasks, a PEO provides end-to-end HR support including payroll, benefits, compliance, and risk management through a co-employment model.

How does HR outsourcing work with a PEO?

When you partner with a PEO, the PEO takes on administrative HR functions such as payroll processing, benefits management, and compliance oversight. Under a co-employment model, the PEO becomes the employer of record for tax and insurance purposes, while your business retains full control over day-to-day operations and workforce decisions.

What is the difference between a PEO and an ASO?

A PEO operates under a co-employment model, shares employer liability, and provides comprehensive HR compliance support with pooled benefits. An ASO acts as a third-party administrator, leaving all employer liability with the client and offering more limited compliance guidance without co-employment.

What HR services can be outsourced?

Businesses can outsource a wide range of HR functions including: payroll and tax processing, benefits enrollment and administration, compliance and regulatory management, HR administrative tasks, recruitment and talent acquisition, employee onboarding and offboarding, performance management, and training and leadership development.

What are the benefits of HR outsourcing for small businesses?

Key benefits include: cost savings (average 27% reduction in HR admin costs with a PEO), time efficiency, access to Fortune 500-level employee benefits, improved compliance with employment laws, reduced risk of payroll penalties, and the ability to focus leadership time on business growth rather than administrative tasks.

What does HR outsourcing not cover?

HR outsourcing does not replace your internal leadership's authority over final hiring, promotion, and termination decisions; your company's culture and employee relationships; face-to-face conflict resolution and coaching; or the actual performance review conversations conducted by your managers.

What is the difference between a PEO and a payroll provider?

A payroll provider focuses solely on processing paychecks, tax withholdings, and year-end filings. A PEO goes far beyond payroll to include benefits administration, HR compliance, risk management, workers' compensation, HR technology, and dedicated HR consulting.

What is the difference between a PEO and an HRO?

An HRO (Human Resources Outsourcer) handles specific HR functions like payroll or recruitment without a co-employment relationship, leaving all employer liability with the client. A PEO provides a single, integrated solution — combining co-employment, shared liability, pooled benefits, compliance management, and HR consulting — through one partner.

What is the difference between a PEO and an HR platform?

An HR platform is a self-service technology tool for managing HR tasks like payroll, onboarding, and benefits. A PEO combines that technology with actual HR experts who provide compliance guidance, risk management, and dedicated consulting — giving businesses both the tools and the team to manage HR effectively.

What is the difference between a PEO and in-house HR?

With in-house HR, your business handles all HR functions with your own staff, bearing all employer liability and fixed overhead. A PEO shares employer responsibilities under a co-employment model, provides access to large-group benefits, offers specialized compliance expertise, and typically costs less than building and maintaining an equivalent internal HR team.

What HR Outsourcing Looks Like with a PEO

Q: How much does HR outsourcing typically cost?

HR outsourcing costs vary based on the provider, services included, and size of your workforce. Some providers charge per employee, others use a flat monthly fee or a percentage of payroll. According to NAPEO research, businesses partnering with PEOs save an average of $1,775 per employee annually through reduced administrative overhead and access to cost-effective benefits programs.

Q: What is co-employment?

Co-employment is the model under which a PEO operates. The PEO becomes the employer of record for tax and insurance purposes and handles administrative HR responsibilities, while the client business retains full control over its employees, day-to-day operations, and all workforce management decisions.

Payroll, compliance, benefits administration—for most small businesses, these functions eat up an average of 54 hours a month, according to the Society for Human Resource Management (SHRM). That's nearly 650 hours a year not spent on customers or strategic initiatives.

That's where HR outsourcing comes in. By definition, HR outsourcing refers to the practice of partnering with external HR experts to handle essential responsibilities, so you can focus on what you do best—growing your business.

So how does HR outsourcing work? HR outsourcing means partnering with a dedicated provider to handle payroll, benefits, and compliance, so your team has the support and expertise to focus on what actually moves the business forward.

One of the most effective ways to outsource HR is through a Professional Employer Organization (PEO). According to a recent study by the National Association of Professional Employer Organizations (NAPEO), businesses that work with PEOs experience:

An average savings of 27% on HR admin costs
10% - 14% lower employee turnover
7% - 9% faster growth
50% lower risk of going out of business

If you're looking to streamline operations, reduce costs, and improve employee satisfaction, HR outsourcing with a PEO might be the perfect solution.

What is a PEO?

A Professional Employer Organization (PEO) is like your business's HR best friend. But what is a PEO, exactly? It's a service that provides the most comprehensive form of HR outsourcing available to businesses today. Instead of just handling one or two tasks, a PEO provides end-to-end HR support, including payroll, benefits, compliance, and risk management. You receive the HR guidance you need from experts without the overhead costs.

How Do PEOs Work?

PEOs take on administrative HR functions, like payroll processing, benefits management, and compliance oversight.

Beyond handling HR tasks, PEOs provide access to comprehensive employee benefits, advanced technology, and cost-savings advantages that would typically be out of reach for smaller businesses. They manage everything from employee onboarding and handbook creation to workplace safety and risk management, helping businesses stay compliant with employment laws while promoting a strong company culture.

Why Businesses Love PEOs:

Access to big-business benefits (think Fortune 500-level perks)
Streamlined HR tasks with advanced technology
Compliance support to avoid legal headaches
Dedicated HR pros to guide you through tough situations

According to NAPEO research, businesses partnering with PEOs save an average of $1,775 per employee annually, primarily through reduced administrative overhead and access to cost-effective benefits programs. This cost advantage becomes particularly significant for businesses with 1-50 employees, where internal HR administration can consume up to 25% of senior management's time. 

The Role of Co-Employment

PEOs operate under a co-employment model, a model which often raises the question: What is co-employment? Simply put, it's a partnership in which the PEO handles the administrative side of HR while you stay in control of your employees and business decisions.

Under this arrangement, the PEO becomes the "employer of record" for tax and insurance purposes, while the company maintains full control over its day-to-day operations and workforce management decisions.

Cost Savings: Reduce expenses related to hiring, training, and maintaining an internal HR team by paying only for the services you need.
Time Efficiency: Free up internal staff from time-consuming administrative tasks like payroll processing and benefits management.
Access to Expertise: Gain specialized knowledge in areas such as compliance, talent acquisition, and risk mitigation from seasoned HR professionals.
Improved Compliance: Stay up to date with complex and evolving employment laws, minimizing legal risks and penalties.
Scalability: Easily adjust HR services to match business growth or downsizing without the hassle of recruiting or layoffs.
Enhanced Employee Experience: Streamline HR processes to provide employees with faster, more reliable support and competitive benefits.
Risk Mitigation: Leverage the provider's expertise to manage sensitive employee data securely and reduce exposure to workplace liabilities.
Focus on Strategic Priorities: Allow your core team and leaders to concentrate on high-impact initiatives like employee development and performance management.

Every HR provider wants to help make your life easier, but they don't all do it the same way. Some focus solely on payroll, while others offer full-service solutions that include benefits, compliance, and risk management. Understanding the differences can help you make the best choice for your business's future.

Modern HR challenges, like complying with labor laws, keeping employees engaged, managing risk, and staying efficient, require smart solutions. Businesses need to understand how different HR providers tackle these issues and what unique advantages they bring to the table. The right HR partner will not only take administrative tasks off your plate but also help you build a thriving, competitive business.

PEO vs. ASO (Administrative Services Organization)

Let's focus on ASOs. They're basically your HR admin helpers. An ASO is a service provider that offers support with administrative HR tasks, such as payroll processing, benefits administration, and HR administration. 

Unlike a PEO, an ASO does not operate under a co-employment model. Instead, ASOs are a practical option for companies seeking simple assistance with HR administrative tasks without outsourcing broader HR management functions. 

While PEOs and ASOs might look similar at first, they work quite differently, and this can really affect how your business runs, your risk exposure, and your costs.

PEOs	ASOs
Establish co-employment relationships	Operate as third-party administrators
Share employer liability	Leave all employer liability with the client
Pool employees for better insurance and benefits rates	Cannot pool employees to leverage economies of scale
Provide comprehensive HR compliance support	Provide limited compliance guidance
Offer integrated payroll, benefits, and HR systems	May offer separate systems for different services

Now, you might be wondering whether to go with a PEO or an ASO. It really comes down to what you need. Think about how much help you want, whether you'd like someone to share the risks with you, and where your business is headed. Are you planning to grow quickly? Expand to new locations? These are the kinds of questions that'll help you pick the right fit.

PEO vs. HRO (Human Resources Outsourcer)

Now, let’s focus on HROs (Human Resources Outsourcers). These service providers help businesses manage specific HR functions by outsourcing them to external experts. Unlike PEOs, which offer comprehensive HR support under a co-employment model, an HRO focuses on individual HR tasks such as payroll processing, recruitment, or benefits administration. HROs are often used by companies that want support in particular areas of HR while maintaining direct control over others. 

HROs have been around for ages, helping businesses delegate their HR work. But here's the thing: as managing employees gets more complicated and there are more rules to follow, the differences between HROs and PEOs become more apparent.

The distinction between PEOs and HRO providers is especially clear when considering risk management. PEOs generally offer stronger, broader compliance programs due to the co-employment model. Conversely, HROs only advise on compliance issues related to their narrow function. When considering data from the Competitive Enterprise Institute that shows businesses face an average of $10,000 in compliance costs per employee annually, the PEO model is better equipped to help mitigate these costs than HROs. 

PEOs	HROs
Single vendor for all HR needs	Multiple vendors may be needed
Shared liability through co-employment	Client retains all employment liability
Access to enterprise-level benefits	Limited benefits options
Dedicated HR consulting team	Variable support levels
Integrated compliance management	Fragmented compliance approach

For businesses weighing these options, the choice often extends beyond simple cost comparisons. While HRO providers can effectively handle specific HR functions, PEOs offer a more integrated and comprehensive approach to workforce management. The co-employment model unique to PEOs provides additional layers of protection and support that become increasingly valuable as organizations grow and face more complex HR challenges.  

PEO vs. Payroll Providers

Payroll providers help make sure your team gets paid correctly and on time. They handle all the nitty-gritty, like figuring out everyone's wages, withholding taxes, handling benefit deductions, and sending out pay stubs. Plus, they keep up with all tax rules and take care of important paperwork like W-2s and 1099s at the end of the year.

Payroll providers and PEOs are very different ways to handle your HR needs. Sure, running payroll might seem straightforward, but it's connected to tons of other HR stuff, like making sure you're following tax laws and managing benefits. A lot of companies start out just using a payroll service, but as they grow, they realize they need way more help than that.

Here's a reality check: the IRS says 40% of small businesses end up paying penalties (about $845 per year on average!) for messing up their payroll taxes. This is where PEOs come in handy—they help you avoid these headaches with their comprehensive compliance guidance.

PEOs	Payroll Providers
Full payroll administration	Payroll processing
Tax management	Basic tax filing
HR compliance and risk management	Limited HR support
Benefits administration	No benefits administration
Highly scalable	Limited scalability
HR technology platform	Time and attendance tracking
Workers' compensation	Limited compliance guarantees

Think about where your company's headed and what kind of rules you need to follow when you're choosing between these options. Sure, payroll providers are great at getting those paychecks out, but there's a lot of other HR stuff they just don't handle.

As your company grows and things get more complicated, like managing your team, handling benefits, and following all those pesky regulations, having a PEO in your corner becomes super valuable. They don't just handle your payroll; they give you everything you need to grow your business without all the HR headaches, such as:

 Payroll processing and payroll tax administration

 Workers’ compensation and employment practices liability insurance

 Human resources support

 Employee health care, other benefits, and/or program administration (optional)

PEO vs. HR Platforms

So, what's an HR platform? It's basically a tech tool that makes all your company’s HR stuff easier to handle. HRIS platforms consolidate payroll, benefits, onboarding, and compliance tracking into a single system, reducing the manual handoffs and data errors that come with running separate tools.

Many of these platforms, like MyFrankCrum, have cool features such as self-service portals where your employees can log in to check their pay stubs, update their info, or look at their benefits without having to bug HR every time. Pretty handy, right?

These days, everyone's going digital with HR, and there are tons of these platforms out there promising to make managing your team a breeze. But here's the thing: while they've got nice features, HR platforms are totally different from what a PEO offers. PEOs typically combine a slick HR technology solution with actual human expertise backing everything up to provide HR consulting services.

This becomes important as your company grows. Sure, HR platforms are functional, but at the end of the day, you may need HR guidance that goes beyond what software can provide. Technology can't handle everything on its own.

PEOs	HR Platforms
HR support from real people	Self-service tools
Expert guidance and consulting	Digital document management
Proactive compliance management	Basic compliance templates
Dedicated service team	Limited customer support
Combined technology and human expertise	DIY approach to HR management
Significant cost savings through economies of scale	No economies of scale for benefits or insurance

The choice between an HR platform and a PEO ultimately comes down to your organization's need for human expertise and support versus a purely self-service, digital solution.

Think of PEOs as giving you the best of both worlds—they've got the tech you need, plus real people who know their stuff to help run your HR. It's like having a super-smart HR system AND a team of experts in your corner. This combo comes in handy when managing your team gets complicated, because sometimes you need both clever software AND actual humans to figure things out.

PEO vs. In-House HR

Should you keep HR in-house or team up with a PEO? Here's the deal: with traditional HR, you're handling everything yourself with your own employees. But with a PEO, you're basically getting a partner who shares both the responsibilities and risks of being an employer.

Working with a PEO comes with some serious advantages. Because they work with lots of companies, they can hook you up with benefits packages that would normally be too costly for smaller businesses to get on their own. Plus, they keep track of all those tricky federal and state rules, so you don't have to worry about messing something up. This is huge when you consider that fighting an employment lawsuit can cost a small business around $125,000!

Money-wise, it's a different ball game too. Running your own HR department means dealing with fixed costs and surprise expenses that can pop up out of nowhere. But PEOs usually charge by the employee or take a percentage of payroll, which makes it way easier to plan your budget and adjust as your company grows or shrinks.

Here's maybe the best part for small businesses: PEOs give you access to HR experts who know their stuff inside and out. Hiring all these specialists yourself would cost an arm and a leg. Instead of being limited by the knowledge of your in-house team, you get a whole crew of HR pros who are experts in everything from benefits to keeping your business legally protected.

1. Define your business needs and goals.
Before selecting an HR outsourcing partner, business owners should identify their primary HR challenges, such as payroll processing, compliance, risk management, or employee relations. It's also important to consider where the business is headed and what HR issues you may confront in the future.

2. Prioritize compliance and risk management.
Legal compliance is an ongoing concern for business owners. When selecting an HR outsourcing partner, consider those that will help you navigate complex labor laws and reduce risks associated with employment regulations, tax compliance, and workplace safety.

3. Leverage HR technology and data analytics.
A strong HR outsourcing partner will provide access to modern HR technology, allowing you to track workforce data, analyze trends, and make better-informed decisions. Plus, automating administrative tasks with an HRIS can make your business far more efficient.

4. Evaluate customer support.
A reliable partner offers responsive assistance, clear communication, and personalized solutions tailored to your business's unique needs. This aspect of a business partnership is often the one that makes or breaks the relationship.

5. Consider long-term scalability.
As businesses grow, their HR needs to evolve. Partnering with an HR provider that offers scalable solutions ensures that HR services remain effective, whether the company expands operations or hires additional employees.

Key Advantages of Partnering with a PEO

Save Time: One of the key PEO benefits is taking specialized, time-consuming administrative tasks off your hands. You'll be freed up to concentrate on more important things like business performance and growth.

Attract & Retain Talent: Offer a sense of security by providing an attractive benefits plan typically offered to Fortune 500s, retirement options, and a safe work environment to employees.

Support & Guidance: Your company will receive reliable assistance and guidance from trusted advisors on a variety of specialized topics.

Save Money: You'll reduce costs compared to doing things yourself and you'll gain purchasing power for benefits, insurance, and other products.

Reduce Risk & Liability: Another PEO benefit is reducing workers' comp claims with an effective safety program. Minimize costly mistakes in payroll and related taxes, benefits, and HR that can put your business at risk.

Consistently Compliant: Using a PEO helps take the burden of the ever-changing state and federal regulations off your shoulders.

Partnering with a PEO isn't just about saving time—it's about scaling smarter.

SMB Success Stories

HR outsourcing through a PEO has proven to be a critical decision for many SMBs, helping them streamline HR functions and focus on core business growth. Here are a few examples of how PEOs positively impact small businesses: 

Jake

Jake owns a small construction company that was struggling to keep up with changing OSHA regulations and labor laws. With expert compliance guidance and training resources from a PEO partner, he was able to improve safety protocols and reduce violations.

Kendra

Kendra's fast-growing tech startup lacked the internal HR infrastructure to handle its expanding workforce. By outsourcing HR to a PEO, the company gained robust HR technology, a streamlined onboarding process, and comprehensive benefits, helping to attract and retain top talent. Plus, she didn't have to spend a penny on extra overhead.

Lee

Lee is the owner of a private medical practice. He wanted to provide competitive employee benefits without incurring excessive costs. With the help of a PEO, the business was able to access high-quality group benefits at reduced rates, improving employee satisfaction and retention.

Pari

Pari's regional retail business faced hiring surges during peak season. Her PEO partner facilitated seamless onboarding and payroll management for seasonal employees, ensuring smooth operations without extra administrative burdens.

Let's talk about HRIS. A Human Resource Information System (HRIS) is a technology-driven solution that helps businesses manage and track HR-related data. HRIS platforms form the backbone of effective HR management, providing sophisticated tools that were once available only to large enterprises.

What's cool about an HRIS is that it handles boring (but super important) stuff like payroll, benefits administration, employee records management, and compliance tracking. Gone are the days of drowning in paperwork or pulling your hair out over spreadsheets. This tech does the heavy lifting for you and helps avoid pesky human errors.

Here's where it gets even better: When you work with a PEO like FrankCrum, you get access to a top-notch HRIS system that integrates with your payroll and benefits. Plus, your employees will love being able to handle their own stuff through the self-service portal. They can check their pay stubs, manage their benefits, and request vacation time without having to bother HR about it.

Long story short: An HRIS makes life easier for everyone, helps your business run more smoothly, and lets your team focus on what they do best instead of getting bogged down by paperwork.

Is HR outsourcing the same as working with a PEO?

Not exactly. HR outsourcing is a broad term for partnering with an outside provider to help manage HR functions like payroll, benefits, compliance, and employee administration. Working with a PEO is one of the best ways to outsource HR because it provides a more comprehensive solution, combining HR expertise, technology, benefits, payroll, workers’ compensation, and compliance support through one partner.

How much does HR outsourcing typically cost?

HR outsourcing costs vary based on the provider, the services included, and the size of your workforce. Some providers charge per employee, while others may use a flat monthly fee or a percentage of payroll. The best way to understand your costs is to request a custom quote tailored to your business needs.

What are the potential risks of HR outsourcing?

The biggest risks usually come from choosing the wrong provider. Poor communication, limited support, unclear service expectations, or a lack of compliance expertise can create frustration instead of relief. That’s why it’s important to choose a partner with strong HR knowledge, responsive service, and solutions that fit your business.

Can a business outsource only certain HR functions rather than the entire HR department?

Yes. Businesses can outsource specific HR functions, such as payroll, benefits administration, compliance support, onboarding, or employee documentation. Others may choose a more comprehensive HR outsourcing solution, such as a PEO, when they need broader support across multiple HR areas.

Does HR outsourcing affect company culture?

HR outsourcing can support your company culture, but it does not replace your leadership team’s role in shaping it. Your business still guides the employee experience, workplace expectations, and day-to-day relationships. The right HR outsourcing partner can help strengthen your culture by improving processes and giving managers better tools and guidance.

How do you choose the right HR outsourcing provider?

Start by identifying the HR challenges you need help solving, such as payroll, compliance, benefits, risk management, or employee support. Then, look for a provider with the right mix of expertise, technology, service, and scalability. A strong HR outsourcing partner should make your business easier to manage, not more complicated.
