PEO vs. Managed Payroll: What's the Difference and Which Do You Actually Need?

"PEO" and "managed payroll" get lumped together constantly in HR vendor conversations. They're not the same thing -- and choosing the wrong one has consequences that go well beyond cost.

Here's the clearest way to explain the difference: with a PEO, your employees are technically employed by the PEO and leased back to you. With managed payroll, your employees are entirely yours -- a service provider just handles the payroll processing. That legal distinction has enormous practical implications for control, cost, flexibility, and what happens if you ever want to change providers.

PEO vs. Managed Payroll: Head-to-Head

When a PEO Actually Makes Sense

PEOs built their business model on one core value proposition: group buying power for benefits. A company with 15 employees cannot negotiate competitive health insurance rates on its own. Through a PEO, those 15 employees join a pool of tens of thousands -- and the rates improve dramatically.

If that's the problem you're solving -- access to competitive group benefits that you couldn't otherwise afford -- a PEO may be the right answer, despite the higher cost and complexity. Justworks, TriNet, and Insperity all serve this market well.

PEOs make sense when:

• You have fewer than 30 employees and cannot access competitive group health insurance rates independently
• You want HR compliance infrastructure -- employee handbook, HR policy framework, workplace training -- included as part of the service
• You're willing to accept shared employment and PEO policy frameworks in exchange for the benefits access and compliance support
• You're in an industry with high workers' compensation risk where pooling through a PEO meaningfully reduces your rates

Where PEOs Create Problems

Co-employment introduces complications that become more significant as your company grows:

• Complex exits. When you leave a PEO, the transition is significantly more involved than leaving a payroll provider. Employees technically change employer relationships, benefits must be re-issued or transferred, open workers' comp claims require resolution, and state unemployment tax accounts must be re-established under your EIN. A well-managed PEO exit takes 60 to 90 days of careful planning.
• Less control over HR decisions. PEOs have standard policies that all co-employed workers fall under. Customizing benefits packages, leave policies, or compensation structures outside PEO standards can be difficult or impossible without negotiating specific carve-outs.
• Cost at scale. PEO pricing is typically 8 to 12 percent of gross payroll. For a 50-person company with $3.5M in annual payroll, that's $280,000 to $420,000 per year. The cost-benefit calculation shifts dramatically as headcount grows -- what made economic sense at 10 employees is prohibitively expensive at 75.
• Not solving the core problem for many companies. Companies that are primarily frustrated by the operational burden of running payroll -- not by benefits access -- often find that a PEO adds cost and complexity without addressing what's actually painful.
• The co-employment label can complicate financing. Some investors and lenders ask questions when employees are technically employed by a third party. While this is rarely a blocking issue, it is something to be aware of during due diligence processes.

The Cost Gap at Scale

The cost difference between a PEO and managed payroll becomes significant quickly. The PEO's percentage-of-payroll pricing model means your cost grows automatically as you give raises and hire more expensive employees -- you're essentially paying the PEO a portion of every salary increase forever.

PEO cost at 10% of gross payroll. BEG at $25–$45 PEPM. Note: PEO cost may be partially offset by benefits savings if your current benefits are significantly more expensive than PEO group rates.

The Co-Employment Risk Most Companies Miss

The most significant risk of a PEO arrangement is not operational -- it's what happens if you ever need to change. Companies that sign a PEO agreement at 15 employees often feel trapped at 60 employees when the cost has ballooned but the exit feels too complicated to manage.

Here's what a PEO exit actually involves:

• Benefits transition. Your employees' health insurance is through the PEO's group plan. Leaving the PEO means their current coverage ends, and you need a new plan in place before it lapses. Benefits brokers typically need 30 to 60 days to set up a new plan.
• Workers' compensation. Claims open at the time of exit need to be resolved or transferred. Depending on your industry and claims history, obtaining independent coverage may cost more than your PEO rate.
• State unemployment tax re-registration. The PEO has been filing unemployment taxes under its EIN. You need to re-establish accounts under your EIN in every state where you have employees, which can take 4 to 8 weeks per state.
• Employee notification and documentation. Employees must be formally notified of the employment change. New I-9 documentation may be required in some cases.

None of this is impossible, but it's a meaningful project -- one that managers typically underestimate when they sign the original PEO agreement. With managed payroll, there is no co-employment to unwind. If you cancel, it's a straightforward provider transition.

The 3 Questions to Ask Before Choosing

Before deciding between a PEO and managed payroll, answer these three questions honestly:

1. Is benefits access your primary problem? If you are currently offering poor health insurance or no benefits -- and losing candidates or employees because of it -- a PEO's group purchasing power may be worth the premium. If you already have a solid benefits package through a broker, the PEO's core value proposition doesn't apply to you.

2. How much operational control do you want? PEOs require you to operate within their HR policy framework. If you have strong company culture, unique compensation structures, or specific leave policies that don't conform to standard PEO offerings, you will hit friction. Managed payroll leaves your HR policies entirely in your hands.

3. What is your likely headcount in 3 years? If you plan to grow from 20 to 75 employees over the next 3 years, model both the PEO cost at 75 employees and the exit cost you will incur when you eventually decide the PEO is too expensive. At $3 to $5M in payroll, the annual PEO premium often exceeds $300,000 -- and the exit work adds another 2 to 3 months of internal effort.

How BEG Managed Payroll Compares to the PEO Model

BEG managed payroll handles what most companies are actually trying to solve when they evaluate PEOs: the operational burden of running payroll each cycle, managing tax compliance across states, and keeping up with regulatory changes.

What BEG does that a PEO also does:

• Full payroll processing each pay cycle -- we run it, you approve it
• Federal, state, and local tax filings and remittances
• Multi-state payroll compliance and registration
• Year-end W-2 and 1099 preparation
• Employee payroll question handling

What BEG does NOT do -- and what only a PEO provides:

• Group benefits plan access and administration through co-employment
• Shared workers' compensation coverage through PEO pooling
• Shared legal liability for HR compliance decisions
• Employee handbook and HR policy templates provided under PEO framework

For companies whose problem is operational payroll burden -- not benefits access -- BEG managed payroll delivers more value at a fraction of the cost, with none of the co-employment complexity.
