How to Choose a PEO: 10 Questions Every Business Owner Should Ask

Are you IRS-certified (CPEO) — and does that matter for my situation?

The IRS Certified PEO program launched in 2014. CPEOs post a bond, undergo annual IRS financial review, and assume sole federal employment tax liability for wages they pay. Non-certified PEOs do not.

The practical implication: if your PEO is a CPEO and fails to remit federal employment taxes, you cannot be held liable. If they are not a CPEO, you can be. CPEOs can also pass through tax credits like the Employee Retention Credit and Work Opportunity Tax Credit directly to you.

Of our six primary partners, all are CPEO-certified. Roughly 50+ PEOs are certified out of 500+ in the market. Lack of CPEO status is not a dealbreaker but it deserves a real explanation.

Who exactly will be handling my account day-to-day — and what is their caseload?

The single biggest predictor of PEO satisfaction is not the technology platform or the benefits package. It is service quality — specifically, whether there is a real person assigned to your account who knows your business and picks up the phone.

Large PEOs often present during the sales process with senior people who have excellent answers. After implementation, you may end up in a shared service queue with a different team entirely. Ask specifically: who will be your named account manager, what is their title and tenure, and how many clients do they manage?

The SHRM industry benchmark is one HR Business Partner per 30 to 50 client companies. Above 50, service quality usually degrades. If the answer is "100+ clients per advisor," expect service to reflect that math.

What health insurance carriers are in your network — and what are the actual plan options?

Benefits quality is one of the primary reasons businesses join a PEO. But "access to health insurance" means nothing without knowing which carriers, which networks, and which plan designs are actually available in your state.

Ask to see the actual plan options for your specific employee zip codes. Carrier networks vary dramatically by geography. A Blue Cross or Aetna plan with a strong network in Denver may have a thin network in a rural market. Request the provider directory for the plan options you are being shown.

Also ask how renewal pricing works. PEOs often quote attractive first-year rates. Find out whether year-two is market-rated or reflects your specific claims experience. Per the Kaiser Family Foundation Employer Health Benefits Survey, average employer premium increases have run 6 to 9 percent annually over the past five years. If a PEO is consistently below that, they are negotiating well.

How is workers comp handled — and what is my rate based on?

PEOs cover workers comp under their master policy, which is one of the most significant potential cost advantages of a PEO arrangement. But not all PEOs underwrite workers comp equally, and not all risk classes are welcome on all master policies.

Ask specifically: what carrier is the master policy with? What rate per $100 of payroll are you quoting for my NCCI class codes? Is that rate based on the PEO's aggregate claims experience or my specific claims history? And what happens to my rate if I have a claim?

Verify your NCCI class codes yourself — the NCCI code lookup is public. Wrong class code equals wrong premium, usually inflated. We have seen proposals with office workers coded as construction labor. The difference is thousands per month. Bureau of Labor Statistics injury and illness data can give you benchmark injury rates for your industry.

What does your all-in pricing include — and what are the add-ons?

PEO proposals frequently lead with an attractive headline rate and then add fees for onboarding, off-cycle payroll runs, benefits administration, compliance filings, or technology modules. By the time implementation is complete, the effective per-employee cost can be 20 to 40 percent higher than the quoted PEPM.

Ask for a complete fee schedule in writing — every charge you could incur in a normal operating year. Then ask: what is not included in this list that you have charged other clients for? A good PEO will answer that question directly.

What states do you have experience operating in — and do you have clients in my industry?

A PEO that runs payroll and HR for professional services firms in five states may not have deep expertise in construction compliance or healthcare staffing regulations. Industry-specific knowledge matters more than most prospects realize during the evaluation.

Ask for client references in your industry and in the states where you operate. Then call them. Specifically ask: what surprised you about working with this PEO, good or bad, that you wish you had known before you signed?

What does the exit process look like?

This is the question almost nobody asks — and the one that causes the most pain when the relationship does not work out.

When you leave a PEO, you need to move your employees to a new benefits carrier, establish new workers comp coverage, set up a new payroll system, and transfer employee data. How the PEO facilitates — or obstructs — that process determines how disruptive the transition is.

Ask specifically: what is the notice period required to terminate? What data do you provide upon exit and in what format? Do you assist with benefits continuity during transition? Are there exit fees?

See our How to Switch PEOs guide for the full exit playbook.

How do you handle employment practices issues — and what does your EPLI coverage actually protect?

Employment Practices Liability Insurance (EPLI) is one of the most valuable components of a PEO arrangement — and one of the least understood. It covers claims related to wrongful termination, discrimination, harassment, and wage and hour disputes.

Ask specifically: what is the coverage limit? What is excluded? Is the coverage a blanket policy or does it require separate underwriting for my risk profile? And critically: in the event of a claim, does the PEO's HR team support me through the process or does it go directly to insurance?

Also ask about the deductible. Some PEO EPLI policies have $25k to $100k deductibles that you pay. That matters. A well-structured PEO relationship means HR advisory involvement before a situation escalates to a claim, not just coverage after the fact.

What happens when something goes wrong?

Every PEO will handle errors eventually. How they handle them is the real test.

Ask for the service level agreement (SLA) document. Good PEOs commit to specific response times: payroll error corrections within one business day, benefits enrollment issues resolved in 48 hours, in-house employment counsel accessible for escalations. If they do not have an SLA document, they do not track service quality.

How do you handle benefits renewals each year?

Benefits premium increases are the single biggest driver of PEO cost escalation. How the PEO negotiates your renewal matters more than the first-year quote.

Ask: do you go to market annually across your carrier relationships? If my experience is favorable, do you negotiate for rate reductions or stability? If unfavorable, do you present alternative plan options so I can choose richness versus cost? Will I see the renewal 90 days before the effective date with a written explanation of changes?

A PEO that answers "rates are just whatever the carriers quote" is not advocating on your behalf. Look elsewhere.
