If you're exploring PEO companies, you're likely feeling the weight of HR responsibilities, rising benefit costs and compliance challenges. Choosing the right PEO partner can lighten that load—boosting efficiency, reducing overhead and helping your business scale with confidence.
In this guide, we’ll walk through how to choose the best PEO companies for your business—from red flags to watch for to the key characteristics that separate top-tier providers from the rest in 2025.
PEO companies—short for professional employer organizations—are partners that help small businesses manage HR, payroll, benefits and compliance. With over 900 PEO companies operating in the U.S., choosing the right one is key to improving efficiency and reducing risk.
This guide will walk you through everything you need to evaluate and compare PEO companies with confidence.
When evaluating PEO companies, look for these key characteristics:
Choosing the right PEO for your business can have a high return on investment, especially for small and mid-sized businesses. Follow these steps to make sure you partner with a trustworthy PEO that aligns with your business needs.
Search for PEO companies by evaluating their online presence. Look for reviews, social media activity and feedback from current clients to gauge a PEO’s reputation.
A reputable PEO will have a consistent online presence, a thorough website and a clear HR leadership voice. Try to narrow your search down to your top three preferred PEO providers.
The more information you have on your top three choices, the better, including their business history, certifications, client base and financial soundness.
In addition to online research, check out news stories and review any available court records on the professional employer organization.
In doing your due diligence, focus on the basics that signal a reputable PEO company:
How long has the PEO been in business? Has it handled businesses similar to yours in size and industry?
Are certified HR professionals available locally or regionally to provide hands-on support?
Look at the types of clients the PEO serves. A diverse and stable client base is a good sign.
Work with certified PEO companies that undergo rigorous IRS assessment, ensuring financial stability and compliance with federal employment taxes. Check that the PEO’s staff have professional HR certifications such as SPHR, SHRM-SCP or CPP.
Not all PEO companies are created equal. If you're comparing providers, look for the IRS-certified PEO (CPEO) designation—fewer than 10% of PEOs in the U.S. have earned it.
Why does that matter to you? Certification means the PEO has passed a comprehensive IRS vetting process for financial stability and tax compliance. It also gives you greater peace of mind: If the PEO handles your payroll taxes, you're protected from liability if they fail to remit them properly.
In short, working with a certified PEO protects your business, your employees, and your bottom line.
The IRS does not endorse any particular certified professional employer organization. For more information on certified PEOs, visit the IRS website.
Another gauge for finding the top PEO companies is having highly qualified staff. Professional human resources certifications indicate that the PEO providers you’re considering are staffed with experienced HR experts.
Look for PEO team members with designations such as:
For added value, ask if each PEO you’re considering offers training opportunities, such as workshops on popular topics like safety, diversity, conflict resolution and curbing harassment.
Request references from the PEO’s current clients who have worked with the PEO for at least a year. This step will help you confirm whether their services match their claims.
One way to start the conversation is to request that the reference rate the PEO on a scale of 1-10 (with 1 meaning they are going to cancel the agreement and 10 meaning they would never leave the relationship).

Because PEO companies manage some employment-related financial responsibilities, such as filing federal employment taxes, it’s important to ensure the PEO has adequate working capital, as well as money in reserve.
PEOs often – and should – have financial audits performed by an independent party. You can request a copy of this audit. It will provide insight into where the company stands financially and show whether the PEO maintains up-to-date and accurate financial records – essential for any reliable PEO.
PEO companies often charge either a percentage of payroll, a flat per-employee-per-month (PEPM) fee or an all-inclusive, flat-rate administrative fee.
Check that the PEO offers comprehensive benefits like PEO health insurance, 401(k) plans, life insurance and disability coverage, making your business more competitive in attracting top talent.

The best PEO companies assign dedicated team members to their clients with clear, direct communication channels. Having a specific point of contact—such as an HR consultant or payroll expert—ensures that you can quickly reach someone familiar with your business whenever questions or issues arise.
This setup not only helps avoid delays but also ensures more personalized, effective support, making the partnership smoother and more responsive to your needs.
Clear communication is key to maximizing the benefits of working with a PEO.
When evaluating PEO companies, one important factor to consider is whether you want to work with a local PEO or a national provider. Both options have distinct advantages, but the best choice depends on your business's specific needs.
Local PEO companies often provide more personalized service, have a deeper understanding of regional employment laws, and are readily available for in-person support.
On the other hand, national PEO companies may offer broader services and larger networks. However, they may not always provide the same level of local expertise or hands-on assistance that small to mid-sized businesses often require.
Choosing between local and national PEO companies is a critical decision.

In today’s hybrid and remote work environment, it’s more important than ever to partner with a PEO that understands the complexities of multi-state compliance.
The best PEO companies offer proactive guidance on employment law changes across states, wage and hour rules, and remote onboarding practices—so you stay compliant no matter where your team works.
Not every PEO offers the same level of service or reliability. Therefore, the choice you make can significantly influence your business' operational effectiveness and financial health.
Here are five red flags to be aware of:
A trustworthy PEO should be able to quickly and comfortably hand over names and contact information for several current clients.
Most PEOs are private companies and, unlike public companies, aren’t required to share financial information. However, you should still be able to receive audited financial statements, which will provide you with a fair assessment of the organization’s financial health.
Audited financials also may reveal vulnerabilities, such as weak internal controls and insufficient cash reserves.
Newer PEO companies may not have the experience or stability of more established providers.
Make sure you know the tenure of the PEO providers you’re considering. Ask the following:
Cybersecurity is a top priority when entrusting a PEO with sensitive employee and company data. The PEO you choose should implement robust security protocols, including encryption, firewall protection, password management and identity validation.
Additionally, they should have a secure cloud infrastructure with multi-layered protection and conduct regular employee training to ensure data is always safeguarded. If the PEO companies you're considering lack these critical security measures, your business could be vulnerable to data breaches.

Of the 900+ PEOs in the United States, fewer than 10% have earned IRS certification (CPEO), which includes rigorous assessments of tax compliance and financial responsibility. PEO providers that aren’t IRS-certified may lack the financial stability and reliability needed to handle your payroll, benefits and workers’ compensation.
Partnering with a certified PEO ensures you’re working with a provider that has been thoroughly vetted by the IRS, reducing the risk of compliance or financial issues.
By recognizing these red flags, you can confidently choose a PEO company that aligns with your business needs and supports your long-term growth.
