The PEO Evaluation Checklist: 25 Things to Review Before You Sign

Calculate the total monthly admin cost divided by headcount. Include all line-item fees, not just the headline rate. Some proposals lead with a low PEPM and add fees for payroll processing, off-cycle runs, or compliance services.

Ask for this in writing. Without a cap, your admin fee can increase significantly at each renewal. Three to five percent per year is reasonable. Uncapped increases are a yellow flag.

Some PEOs charge $500–$2,000 to set up your account. These are often waived entirely, particularly when working with an advisor. Always ask.

Bonus runs, final paychecks, corrections. Some PEOs charge $50–$200 per off-cycle payroll. For companies with frequent exceptions, this adds up.

Request the specific plan documents, not a summary sheet. For health, dental, and vision options available in your employees' locations. Carrier networks vary dramatically by geography. A PEO with excellent plans in one region may have limited options in another.

Ask specifically: is renewal pricing based on the PEO's aggregate claims pool, or is it experience-rated to your group's specific claims? If your group has a bad year, will your rates reflect it? The answer materially affects the long-term economics of the arrangement.

Employees need to know their FSA grace period and run-out window. Confirm the deadline for submitting claims after plan year end, typically 30-90 days. On exit, confirm the post-termination claims window.

Request the fund menu and expense ratios. Some PEO retirement plans have limited investment options or charge plan-level fees that are not immediately visible. Compare these against what your employees could access in a standalone plan.

Get the specific rate for your class codes before signing. For companies with physical risk exposure, this is often the most important financial variable in the entire evaluation.

Under the PEO's master policy, your claims may be pooled with other clients, or they may be experience-rated specifically to your account. Ask explicitly: if we have a significant claim this year, does that directly affect our renewal rate?

The PEO's claims administrator handles investigation, negotiation, and defense. A slow or careless process drives up your experience mod and future rates. Ask: what is the average claim closure time? Are contested claims defended by attorneys, or settled quickly to close the file? Get the name of the claims administrator and the escalation process for any claim you disagree with. Small differences in handling create large differences in your five-year workers comp cost.

CPEO status transfers federal employment tax liability from you to the PEO under the Small Business Efficiency Act. If a CPEO fails to remit payroll taxes to the IRS, you are not on the hook. Non-certified PEOs do not provide this protection, though many operate reputably. Roughly 50 of 500-plus PEOs in the market carry CPEO status. Verify current status directly on the IRS CPEO listing, not just the PEO's marketing.

ESAC (Employer Services Assurance Corporation) is a separate industry accreditation focused on financial stability, ethical business conduct, and regulatory compliance. It requires quarterly financial reviews. ESAC does not transfer tax liability the way CPEO does, but it provides independent confirmation of operational health. Roughly 30 to 40 PEOs currently hold ESAC accreditation. Check the ESAC public directory to confirm.

PEO licensing varies by state. Some states require a specific PEO license. Others require registration only. A few require the PEO to hold a bond amount inside the state. Ask for the PEO's state-by-state licensure summary. Multi-state employers with any distributed workforce need to confirm coverage in every state where they employ someone, including states with one remote employee, before the contract can execute cleanly.

Fidelity bonds protect employers if the PEO fails to remit payroll taxes, benefit premiums, or workers comp premiums. Bond size scales with PEO size. Smallest CPEOs hold $1M. Largest hold $50M or more. Ask specifically: is your business named as a beneficiary under the bond in the event of default? Some bond structures only cover federal tax liability, not benefit premium or workers comp premium liability.

The person presenting during sales is often not the person who will actually manage your account. Ask for the name and title of your dedicated HR Business Partner and ask how many clients they manage. Best practice is 30 to 50 clients. If the answer is significantly higher, service will reflect that.

Get this in writing as a service level commitment. For urgent employment matters, 24-hour response is the baseline. For routine questions, 48-72 hours. If the PEO is not willing to put response time commitments in the agreement, ask why.

Multi-state employment law compliance is not a side project. Ask specifically: how many attorneys and dedicated HR compliance advisors are on the PEO's team? Are they available for direct consultation, or gated through a portal ticket system? A PEO whose compliance team is the same people running payroll operations will not give you the depth you need when an EEO claim, ADA accommodation dispute, or wage and hour complaint lands on your desk. Ask for their credentials and average response time on compliance questions.

Most PEO contracts require 60 to 90 days written notice. Some require 90 to 120 days. Know this number before you sign. It determines your minimum planning window for any future exit.

You need employee records, payroll history, benefits enrollment history, and workers comp claims data when you leave. Ask specifically what format this data comes in and whether it is compatible with major payroll systems. Some PEOs deliver data in proprietary formats that require significant work to migrate.

Some PEOs charge $1,000 to $5,000 in deconversion fees. These are negotiable, both before signing and at exit. Get the exit fee structure in the contract before you sign. If there is no exit fee, get that confirmed in writing as well.

Most PEOs include Employment Practices Liability Insurance covering wrongful termination, discrimination, harassment, and retaliation claims. Ask specifically: what are the coverage limits per claim and aggregate? Is defense included, or is it in addition to indemnity limits? What is the retention (deductible) per claim? Are wage and hour class actions covered? Wage and hour is the largest single EPLI exposure for most SMBs and is often excluded or sub-limited. Confirm what happens to coverage on exit and whether tail coverage is available.

Standard PEO implementation is 4 to 8 weeks. Complex cases with multi-state exposure or 100-plus employees can run 8 to 12 weeks. Ask for the specific timeline for your headcount and complexity, the named implementation project manager, and the deliverables and dates in writing. Implementation dictates whether the first three months feel smooth or feel like you traded one HR problem for another.

The PEO administers benefits, meaning current carriers change on the effective date. Ask: does the effective date match your current plan year end, or does it create a mid-year transition? Mid-year benefit changes require careful employee communication and can create deductible reset issues. If 401(k) is affected, understand the plan termination or merger process. Get the transition plan in writing before signing. Employee-facing communication timing is worth a specific conversation.

Every PEO shows a polished demo. Ask instead to log into a sandbox environment with your headcount, state footprint, and payroll frequency loaded. Test running a payroll, adding a new hire, submitting a benefits change, generating a report. If the platform slows, freezes, or requires help from the sales rep to complete basic tasks, that is what your team will experience in month two. A live-data demo is the difference between what the platform promises and what it actually does.
