Paying people in other countries sounds straightforward until you discover that each nation runs on its own tax rules, social contribution schedules, currency requirements, and employment laws. The wrong setup doesn’t just cause administrative headaches; it creates real legal liability. US companies expanding internationally often find this out the hard way, and by then it’s already expensive.
Understanding what the most popular global payroll models are before you hire abroad saves real time and money. Here are four structures companies use most often, along with what each one actually involves.
Employer of Record (EOR)
An Employer of Record – commonly called an EOR – is a third-party organization that becomes the legal employer of your international staff on paper, while your company keeps day-to-day management control. When you work with global payroll experts through an EOR arrangement, payroll taxes, statutory benefits, local employment contracts, and in-country compliance filings all sit with the EOR rather than your own business. That structure means you don’t need to establish a foreign legal entity – a process that typically takes three to six months and costs tens of thousands of dollars in legal and registration fees alone – before you can legally pay a single employee abroad.
EORs work particularly well for US companies looking to test a new market, bring on a small number of international employees, or move fast without waiting on entity registration. The model has grown sharply: according to a 2025 report by Globalization Partners, the employer-of-record market exceeded $6 billion globally and keeps expanding as remote work normalizes cross-border hiring. Cost is the tradeoff. EOR fees typically run between $400 and $800 per employee per month, depending on the country and service scope. For companies with a small headcount in a new market, that fee usually comes in well below what entity setup and local HR would cost. For companies with fifty or more employees in a single country, the math shifts, and other models may start looking more attractive.
Professional Employer Organization (PEO)
A Professional Employer Organization, or PEO, operates through a co-employment arrangement rather than a full legal employer transfer. Both your company and the PEO share employer responsibilities in that setup. Your business retains strong legal standing as the employer – including liability for local employment law compliance – while the PEO handles payroll administration, benefits pooling, and HR support. The key practical difference from an EOR is that a PEO generally requires your company to already have a registered legal entity in the country where the employees work; without that local entity, a standard PEO arrangement simply doesn’t apply.
PEOs appeal to mid-size companies that have already planted a flag in a market and want to cut administrative burden without fully handing off employer responsibility. They’re common in countries like Canada, the United Kingdom, and Germany, where US companies have set up subsidiaries but don’t have the local HR infrastructure to run payroll on their own. Pricing tends to be a percentage of total payroll – often between 2% and 8% – rather than a flat per-employee fee, which can make PEOs cost-effective at higher headcounts. But co-employment carries nuance. Each country treats the employer-of-record split differently, and in some jurisdictions the co-employment model creates ambiguity around termination liability, benefit obligations, and tax classification that your legal team needs to review before you sign anything.
In-House Global Payroll
In-house global payroll means your company directly processes payroll for international employees through your own internal team and systems, typically supported by country-specific payroll software or local payroll processors in each market. This model gives you the most control. Your finance and HR teams own the process end-to-end, from tax filing to benefits administration to off-cycle payments. Large multinationals with thousands of employees across multiple countries often prefer this model because the cost per employee drops significantly at scale, and internal ownership reduces dependency on third-party vendors for time-sensitive payroll runs.
The operational requirements are demanding. Running payroll in-house across even three or four countries requires knowledge of employment law and tax codes in each location, local bank accounts or payment infrastructure in each market, and a team or set of vendors who can manage statutory filing deadlines that differ by jurisdiction. Germany, Japan, and Brazil each have payroll rules detailed enough to require dedicated local specialists. A missed social contribution deadline in France carries automatic penalties from URSSAF that compound quickly. US companies that choose in-house global payroll typically already operate at a scale where those compliance investments pay off, or they serve industries like financial services where data sovereignty requirements make third-party processing impractical.
Managed Global Payroll (Aggregator Model)
The managed global payroll model – sometimes called the aggregator model – sits between full in-house ownership and a single-vendor EOR. A central provider coordinates payroll across multiple countries by managing a network of in-country payroll providers on your behalf. Your company gets a single point of contact and often a single dashboard, while the aggregator routes payroll data to local partners who handle country-specific processing and compliance. It’s a practical middle ground for companies operating in many countries that don’t want to build internal teams in each one or depend on a single EOR for everything.
The aggregator model works best for companies with an existing legal entity structure across multiple markets, usually those past the growth stage and operating in ten or more countries at once. The central provider standardizes data formats, reporting, and vendor management, which cuts the administrative burden of juggling twenty different payroll vendors independently. The catch? Oversight sits primarily with the aggregator’s network, not your team. If a local in-country partner misses a filing or processes a tax code change incorrectly, the error still lands on your books. That’s why vetting the aggregator’s local-partner network, their error resolution process, and their response-time commitments matters just as much as evaluating the platform itself.
Conclusion
Each global payroll structure reflects a different trade-off between cost, control, speed, and legal risk. EORs prioritize speed and reduce entity requirements. PEOs share employer responsibility but need a local entity in place. In-house models offer maximum control at scale. Aggregators simplify multi-country coordination without requiring full internal infrastructure. The right answer for your company depends on how many countries you operate in, how quickly you need to move, and how much compliance ownership your team can realistically carry. Knowing what the most popular global payroll models are gives you a real starting point for that decision.
