Companies expanding into a new country usually land on one of two paths: hire through an International PEO, or send an existing employee on a formal global assignment. These solve different problems, and choosing the wrong one tends to show up later as either unnecessary cost or unnecessary risk. Here’s how the two actually compare.
Two Different Ways to Put Talent in a New Country
An International PEO is built for hiring new, local talent in a country where your company doesn’t yet have a legal entity. A traditional global assignment is built for relocating an existing employee, someone already on your payroll, into a new country to fill a specific role, often for a defined period of time. The starting point for each is different: PEO answers “how do we legally hire someone here,” while a global assignment answers “how do we move someone we already employ, there.”
That distinction drives almost every other difference between the two approaches.
What International PEO Actually Does
An International PEO acts as the legal employer of record in the target country, handling payroll, tax withholding, benefits administration, and compliance with local labor law, while your company retains control over the employee’s day-to-day work and responsibilities. This bypasses the need to establish a legal entity before you can legally employ someone in that market.
The PEO also absorbs classification risk. If a worker who should legally be classified as a full-time employee is instead treated as a contractor, many countries impose significant fines and penalties on the hiring company. An International PEO manages this classification correctly from the start, which matters most in countries with aggressive labor enforcement.
What a Traditional Global Assignment Actually Does
A traditional global assignment keeps the employee on your existing payroll and legal structure, typically because your company already has an entity in the destination country or is willing to navigate the tax and legal complexity of employing someone across borders directly. Each assignee gets a dedicated Global Assignment Manager who handles a comprehensive needs assessment, coordinates visa and immigration paperwork, and acts as the single point of accountability for every service involved in the move, from pre-assignment planning through the employee’s eventual repatriation.
This path is built around continuity. The employee doesn’t change employers, their tenure and benefits carry over, and the assignment is typically structured with a defined start and end date tied to a specific business objective, like opening a new office or transferring specialized expertise to a growing market.
Cost Comparison: Entity Setup vs. Service Fees
Cost is often the first thing that pushes companies toward one option or the other, and the numbers aren’t close. Establishing a foreign legal entity typically costs around $20,000 upfront, with annual maintenance running several times that once you factor in local accounting, legal compliance, and administrative overhead. An International PEO replaces that with a service fee plus the cost of the employee’s payroll, which more than halves the total cost of operating in a new market, especially for a company testing whether a market is worth a long-term investment.
A traditional global assignment carries different cost drivers. Because the employee remains on your existing payroll and often relocates with family, the costs show up in relocation services, housing, schooling, and the assignment premium many companies pay to make an international move worthwhile for the employee. These costs tend to be justified by what the assignment accomplishes, transferring institutional knowledge or leadership capability into a new market, rather than compared directly against entity setup costs, since the two solve different problems.
Speed to Market
International PEO is built for speed. Because there’s no entity to establish, companies can typically begin operating and legally employing workers within days rather than months. This matters most when a company needs to test a market opportunity quickly or respond to a time-sensitive business need without committing to the months-long process of entity formation.
A global assignment moves on a different timeline entirely. Visa and immigration processing alone can take weeks or months depending on the destination country, and that’s before accounting for the relocation logistics of moving an employee and potentially their family. Companies that need talent in a new market within days should generally look toward PEO; companies planning an assignment with a longer lead time have more flexibility here.
Compliance and Misclassification Risk
Both approaches carry compliance obligations, but they sit in different places. With International PEO, the compliance burden largely transfers to the PEO itself, since they’re the legal employer responsible for correct classification, tax withholding, and adherence to local labor law. This is particularly valuable in markets where labor law enforcement is aggressive and misclassification penalties are steep.
With a traditional global assignment, compliance responsibility stays with your company, particularly around visa and immigration requirements, which have grown more complex as more countries tighten enforcement and introduce new visa categories for different types of international workers. A Global Assignment Manager helps navigate this, but the underlying legal responsibility doesn’t shift the way it does with a PEO arrangement.
Employee Experience: PEO vs. Assignment
For the employee, these two paths feel meaningfully different. A worker hired through an International PEO is typically a new local hire, not someone being uprooted from an existing role, so there’s no relocation stress, no family disruption, and no adjustment to living in an unfamiliar country. The PEO arrangement is largely invisible to them; they experience it as a normal job with a local employer.
An employee on a traditional global assignment experiences something much bigger: uprooting a household, often relocating a spouse and children, adjusting to a new culture and sometimes a new language, all while taking on new job responsibilities in an unfamiliar market. This is exactly why assignment support tends to be so comprehensive, covering everything from cultural training to school searches to home finding, since the personal disruption is real and directly affects whether the assignment succeeds.
When International PEO Is the Better Fit
International PEO tends to make the most sense when a company is testing a new market without committing to a long-term presence, hiring local talent rather than relocating existing employees, or needing to move quickly without the lead time entity formation requires. It’s also a strong fit for companies uncertain whether a market will pan out, since exiting a PEO arrangement is far simpler and less expensive than unwinding a legal entity.
When a Traditional Global Assignment Is the Better Fit
A traditional assignment fits better when the goal is transferring specific institutional knowledge, leadership capability, or specialized expertise that can’t easily be hired locally. It also makes sense when a company already has an established entity in the destination country, or when the assignment is tied to a strategic initiative, like launching a new office or leading a market entry, that benefits from having a trusted internal employee physically present rather than a newly hired local team.
Can You Use Both?
These aren’t mutually exclusive. Many companies use International PEO to establish an initial local presence and test a market, then transition to direct hiring or send an assignee once the business case for a long-term presence is clear. Others run both simultaneously, using PEO for local hires while sending a small number of assignees to lead the operation during its early stages. The right combination depends on how quickly the company needs to move and how much long-term commitment the market justifies.
Getting Started
If you’re weighing whether International PEO or a traditional global assignment fits your company’s expansion plans, the answer usually comes down to whether you’re hiring new local talent or relocating someone you already employ, and how much certainty you have about committing to that market long-term.
