PEO vs EOR: What's the Difference and Which Do You Need?
PEO and EOR solve different problems. One is for domestic HR outsourcing, the other is for compliant international hiring.
Is it right for you?
- Are your employees based in a country where your company has a legal entity?
- Do you have at least 5-10 employees to meet typical PEO minimums?
- Are you trying to outsource HR admin domestically, or achieve compliance in a foreign country?
- Is your goal cost savings on benefits, or avoiding the expense and delay of setting up a foreign entity?
- Do you need co-employment (PEO) or do you want the vendor to be the legal employer entirely (EOR)?
- What is your budget per employee per month, PEOs typically run $79-$200+ PEPM, EORs run $500-$699+?
Quick verdict
If your team is entirely US-based and you want to offload HR admin and access better benefits, a PEO like Justworks or TriNet is the right tool. If you're hiring someone in a country where you don't have a legal entity, full stop, you need an EOR like Deel, Remote, or Oyster, not a PEO.
The short answer: two tools for two very different problems
PEO and EOR are frequently lumped together in conversations about HR outsourcing, but they address fundamentally different situations. A Professional Employer Organization (PEO) enters a co-employment relationship with you and your existing employees, both companies are technically employers. PEOs are almost exclusively used domestically (primarily in the US), helping small and mid-sized businesses access better benefits, streamline payroll, and offload compliance headaches without surrendering control over day-to-day management.
An Employer of Record (EOR) goes further: the EOR company becomes the sole legal employer of the worker in a foreign country, taking on full liability for payroll taxes, statutory benefits, labor law compliance, and termination procedures. This is the mechanism you need when you want to hire someone in Germany, Portugal, Brazil, or any country where you don't have a registered legal entity. As one commenter on r/Solopreneur put it: 'For overseas hires, an EOR assumes full legal employer responsibilities per country, appropriate when you want to shift headcount risk and provide full benefits and taxes. A PEO offers co-employment and gives payroll/benefits support while you retain some legal responsibility.'
The confusion is understandable because some vendors, notably Remote.com, now offer both products. But the underlying mechanism is different, and choosing the wrong one doesn't just waste money; it can leave you non-compliant in jurisdictions with strict misclassification rules.
Quick comparison: PEO vs EOR at a Glance
| Factor | PEO | EOR |
|---|---|---|
| Legal structure | Co-employment (both you and PEO are employers) | EOR is sole legal employer |
| Geography | Domestic (US-focused); requires you to have an entity | International; no entity required |
| Employee minimum | Typically 5–50+ employees | Usually no minimum (hire 1 person) |
| Typical cost | $79–$200+ per employee/month | $499–$699+ per employee/month |
| Benefits pooling | Yes, access large-group rates | Local statutory benefits only, or EOR-arranged |
| Best for | US SMBs wanting HR outsourcing | Companies hiring internationally without entities |
| Examples | Justworks, TriNet, Insperity | Deel, Remote, Oyster HR |
One important nuance: some PEOs have added EOR products. Justworks, for example, offers its own EOR product at $599/month per employee on top of its domestic PEO plans. Remote.com similarly has a US PEO starting at $99/month per employee and a global EOR at $599/month per employee. But these are genuinely separate products operating on different legal models, buying the PEO plan doesn't unlock international hiring compliance.
Pricing breakdown: what you'll actually pay
PEO pricing (US domestic): Justworks charges $79/month per employee for its Basic PEO plan (compliance, support, HR tools) and $124/month per employee for its Plus plan (full HR + benefits). TriNet does not publish fixed rates, pricing is custom based on company size, industry, and geography, typically quoted as a flat per-employee-per-month (PEPM) fee. Insperity also uses custom quote pricing. For international contractors specifically, Justworks charges an additional $599/month per employee through its EOR add-on.
EOR pricing runs significantly higher, which makes sense given the legal liability and in-country infrastructure involved. Remote.com's EOR is listed at $599/month per employee (discounted from $699). Oyster HR's EOR plan is $699/month per employee, with annual discounts available. Deel's EOR pricing is 'speak to sales' only, though market-rate estimates from user discussions on Reddit put typical EOR costs at $300–$600 per person per month for basic plans, with full-service packages higher. These figures are per employee on top of the employee's actual salary and local employer contributions (social security, etc.).
One frequently overlooked cost with EORs is employer social security and statutory contributions, which vary dramatically by country. As documented in detail in r/eorfortech, hiring in Portugal via an EOR means an additional ~23.75% employer social security contribution on the full annual salary, including the mandatory 13th and 14th month payments. A €60,000 annual package can cost employers nearly €74,250 all-in before the EOR fee. These structural cost surprises are something to discuss with any EOR before signing a contract.
When to use a PEO (and when It Won't Work)
Use a PEO if: your employees are all in a country where you already have a legal entity (almost always the US), you have at least 5–10 employees (most PEOs won't take smaller clients), and your primary goal is accessing better group health insurance rates, outsourcing payroll tax admin, and reducing HR compliance burden. PEOs are particularly effective for startups that want to offer Fortune 500-level benefits to attract talent without building out an internal HR team.
The benefits pooling aspect is the real value proposition of a PEO that EORs can't replicate domestically. By co-employing workers across thousands of small businesses, PEOs negotiate group health, dental, vision, 401(k), workers' comp, and other benefits at rates that a 15-person company could never achieve independently. This is why Justworks and TriNet emphasize benefits quality so heavily in their marketing.
PEOs will not solve your international hiring problem. Multiple Reddit users have discovered this the hard way. As one user on r/Solopreneur explained: 'PEOs usually require you to already have a legal entity in that country, so they mostly work for domestic or where you already operate. If you don't have an entity yet, an EOR is typically the safer route.' If you want to hire someone in Canada, the UK, Germany, or anywhere else without opening a subsidiary, a PEO relationship does not give you that.
When to use an EOR (and Its real Limitations)
An EOR is the right tool when you want to hire full-time employees in a country where you have no legal entity. The EOR company has existing entities in dozens or hundreds of countries, employs the worker legally on your behalf, handles local payroll, taxes, benefits enrollment, and termination compliance, and bills you a flat monthly fee per employee. This avoids the 6–18 month process and $20,000–$50,000+ cost of setting up a foreign subsidiary.
The main limitation of EORs is cost at scale. At $500–$700 per employee per month, running 10 employees through an EOR adds $60,000–$84,000 per year in fees alone, before salaries. At that point, the economics of opening a local entity often start to favor the entity route. Most practitioners recommend evaluating the entity setup when you have 10+ employees in a single country for the long term.
EOR services also vary significantly in quality. The compliance infrastructure, legal response times, and local knowledge differ considerably between providers. One user in r/eorfortech documented a specific failure mode with EOR salary structuring in Portugal: EOR providers who treat monthly gross salary as a 12-month base, then add the mandatory 13th and 14th month payments on top, can inadvertently inflate the total annual cost by ~€10,000 on a €60,000 package. Always ask your EOR to define salary on an annual basis inclusive of all statutory payments before signing.
PEO Providers: Justworks vs TriNet vs Insperity
Justworks is generally the most transparent on pricing and is well-regarded for its clean platform and strong customer support. Justworks Basic starts at $79/month per employee; the Plus plan at $124/month adds access to medical, dental, and vision benefits through United Healthcare and Aetna. Justworks works best for companies under 200 employees, particularly in professional services and tech. It is ESAC-accredited and IRS-certified as a PEO. Justworks also now offers a standalone international EOR product at $599/month per employee.
TriNet positions itself as a premium PEO with deep industry specialization, it has purpose-built configurations for tech, life sciences, financial services, and retail. Pricing is custom-quoted (PEPM-based) and not published publicly. TriNet is also ESAC-accredited and IRS-certified, and it provides access to benefits through large carriers. TriNet acquired Zenefits in 2022, which gives it HR platform capabilities, though some users note the integrated platform experience can feel uneven.
Insperity is one of the largest PEOs in the US by employee count (serving businesses with 5–5,000 employees) and is known for its HR consulting depth and risk management services. Insperity does not publish pricing publicly; quotes are custom. It now offers three tiers: HR 360 (full-service PEO), HR Core (streamlined platform), and HR Scale (Workday-powered for larger organizations). Insperity is better suited to mid-sized companies that want strategic HR advisory alongside administrative outsourcing.
EOR Providers: Deel vs Remote vs Oyster
Deel is the largest EOR provider by revenue and covers 100+ countries. It has expanded well beyond EOR into payroll, contractor management, immigration, and HR software. Deel pricing is quote-based for EOR; its G2 profile (4.8/5 based on 10,000+ reviews as of mid-2026) reflects strong user satisfaction, though some enterprise users flag that support quality can vary by region. Deel is particularly strong for tech companies managing a mix of contractors and full-time international employees.
Remote.com competes closely with Deel and differentiates on its 'owned-entity' model, meaning Remote claims to operate its own legal entities in the countries it covers, rather than using local third-party partners (a distinction that affects liability and compliance depth). Remote's EOR is priced at $599/month per employee (current promotional rate). Remote also offers a US PEO starting at $99/month per employee. Its Trustpilot presence is consistently strong, and the platform includes built-in equity and HRIS features.
Oyster HR targets globally distributed startups and mid-market companies, with EOR in 120+ countries at $699/month per employee (annual discounts available). Oyster distinguishes itself with its 'Employment Eligibility' tool that surfaces country-specific hiring risks before you commit, and it has a strong focus on benefits equity across geographies. For very early-stage teams hiring their first international employee, Oyster's guided onboarding experience is frequently cited as easier than Deel's more enterprise-oriented flow.
FAQ
Can a PEO hire employees in other countries? Generally no, unless the PEO also offers a separate EOR product. Traditional PEO arrangements require your company to already have a legal entity in the country where the employee works. Some PEO providers like Justworks and Remote have layered on EOR services, but these are separate offerings with different pricing and legal structures.
Do I need a minimum number of employees to use a PEO? Most PEOs require at least 5 employees, with some requiring 10–25. TriNet and Insperity are more flexible for smaller counts in some cases, but if you have fewer than 5 US employees, a standalone payroll solution (Gusto, Rippling, ADP) may be more practical than a PEO.
Is an EOR considered co-employment? No. In an EOR arrangement, the EOR is the sole legal employer, there is no co-employment. This is the key legal distinction from a PEO, where both your company and the PEO share employer status. With an EOR, the worker is employed by the EOR's local entity, not by your company, in that country.
When does it make sense to open a foreign entity instead of using an EOR? The general threshold is 8–12+ full-time employees in a single country over the long term. At that scale, EOR fees often exceed the annualized cost of entity setup and maintenance. Opening an entity also gives you greater control over benefits design, employment contracts, and intellectual property protection.
Can the same vendor provide both PEO and EOR? Yes, Remote.com, Justworks, and a few others offer both. But the products operate on different legal rails. Using a vendor's PEO for your US employees and that same vendor's EOR for your international hires is a common and sensible arrangement that consolidates HR data into one platform.
