If you’re running a growing business, you’ve likely felt the HR squeeze. Payroll, benefits, compliance, onboarding, offboarding; it all adds up fast. And handling it in-house without a full HR department? That’s a recipe for burnout or costly mistakes.
It’s no surprise, then, that more business owners are looking to outside HR support, like Professional Employer Organizations (PEOs) and employee leasing companies. These third-party services promise to lighten the administrative load, but it can be hard to figure out how they work and if they would be a good fit for you.
This article walks through the key differences, benefits, and tradeoffs, so you can make an informed and confident choice for your business.
What’s so hard about Human Resources?
HR isn’t just paperwork. It’s legal, financial, and people-related all at once. And the stakes are high.
- A missed payroll tax deadline? That’s a fine.
- An unclear employee policy? That’s a lawsuit waiting to happen.
- No benefits? That’s a talent retention issue.
For many small businesses, DIY HR starts as a necessity. But as you grow, that patchwork system can get risky fast and keep you stuck in the weeds instead of focused on growth.
What is a PEO?
A Professional Employer Organization (PEO) enters into a co-employment relationship with your business. Here’s what that means:
- You still manage your employees’ day-to-day work and responsibilities
- The PEO becomes the “employer of record” for tax and benefits purposes
This setup allows your business to tap into the PEO’s larger employee pool to access:
- Better rates on health insurance and retirement plans
- Expertise in HR compliance, payroll taxes, and workplace safety
- Support for employee handbooks, onboarding, and performance policies
In short, a PEO helps you act like a bigger business, without needing an in-house HR team.
What is employee leasing?
Employee leasing is a different model altogether. Instead of co-employment, a leasing company hires the employees and “loans” them to your business.
Here’s what that looks like in practice:
- The leasing company is the legal employer
- You still oversee the employees’ daily work, but the leasing firm may have more say in employment terms or policies
- Leasing is typically short-term or project-based, not a long-term partnership
If you need quick staffing help or want to test a role before hiring, leasing might fit. But if you're looking for lasting HR infrastructure, a PEO likely makes more sense.

Why should I consider a third-party HR partner?
Outsourcing HR isn’t just about saving time. It’s about doing it right.
A good PEO or leasing company can help you:
- Save money on benefits through group buying power
- Access health, dental, vision, and retirement plans that attract top talent
- Avoid legal pitfalls by staying up to date on employment laws
- Reduce paperwork so your team can focus on operations
- Scale HR support as your business changes
It’s about moving from reactive to proactive HR.
What is typically included with a third-party HR partner?
Here’s what a strong third-party HR partner should bring to the table:
- Payroll Management: On-time, accurate paychecks and tax filings
- Benefits Administration: From health insurance to retirement plans
- Regulatory Compliance: Keeps you aligned with federal, state, and local laws
- Risk Management: Workers’ comp coverage and safety programs
- HR Policy Support: Employee handbooks, onboarding, offboarding, and more
The best partners act like an extension of your team; not just a software vendor.
How do I choose the right partner?
Before you sign a contract, step back and clarify a few things:
- What kind of help do you really need? Full HR overhaul or just help with payroll and compliance?
- How much control do you want to keep? Some business owners prefer to retain hands-on control over hiring policies and employee communication.
- What are your non-negotiables? Maybe it’s health insurance, maybe it’s workplace safety support. Prioritize what matters most.
Then, dig into the details:
- Ask about pricing: Is it a flat fee, per-employee cost, or percentage of payroll?
- Read the fine print on contracts: Watch for liability terms, cancellation clauses, and service level expectations
- Check references and reviews, especially from businesses like yours
The Bottom Line
Outsourcing HR doesn’t mean giving up control. It means choosing to focus your energy where it counts while letting experts handle the administrative and compliance burdens.
Whether you need a long-term partner like a PEO or short-term help from an employee leasing company, the first step is the same: get clear on what you need. From there, research your options, ask smart questions, and lean on trusted advisors if needed.
When your HR runs smoothly behind the scenes, your business can shine out front.
