Employ
Recruit
A US ad agency needs three motion designers in Buenos Aires for a six-month brand launch. The CMO calls a global staffing firm. The CFO calls an Employer of Record. They both come back saying “we can do this.” Both quotes look reasonable. Both pitches sound similar.
They’re solving different problems.
A staffing agency finds the people. An Employer of Record employs the people. The first is a recruiting and placement service. The second is a compliance and payroll service. You can use them together — many companies do — but if you’re picking just one, picking the wrong one is the kind of mistake you only realize six months in, when the project ends and you discover you can’t actually convert a “staff agency contractor” into a long-term hire without restarting the engagement entirely.
This guide is the practical comparison. We’ll walk through who’s actually the legal employer in each model, the cost math, the speed-to-hire reality, the compliance picture, and a decision flow you can use before you commit. If you’re hiring in multiple countries, this comparison fits inside our broader global recruitment strategy playbook.
The 30-second Answer
- Staffing agency finds and supplies workers — usually for short-term projects, peak demand, or roles you don’t want to hire long-term. They handle recruiting and often the basic employment relationship for the duration of the placement. Best when you need bodies fast and don’t intend to keep them.
- Employer of Record (EOR) is the legal employer of your hire — usually long-term, in a country where you don’t have a legal entity. The EOR doesn’t recruit; you bring the candidate. Best when you want a permanent relationship with a specific person abroad without setting up a foreign subsidiary.
If you’re staffing a 3-month project with people you’ll never see again: staffing agency. If you’re hiring a senior engineer in Mexico City who you want on the team for 5 years: EOR.
What is a Staffing Agency, Exactly?
A staffing agency (also called a temp agency, recruitment agency, or workforce solutions firm) is a third party that supplies workers to client companies. The agency:
- Recruits and screens candidates against your role requirements
- Places workers into your business, usually for defined assignments
- Often acts as the legal employer for the worker (W-2 in the US, PAYE in the UK) — but not always
- Charges you a markup on the worker’s pay rate (typically 30-100%)

The legal employer varies. In W-2 staffing, the agency is the employer — they handle payroll, taxes, workers’ comp, benefits. In 1099 staffing, the agency is just a broker; the worker is technically self-employed (with all the misclassification risk that implies — see our EOR vs Independent Contractor guide).
What is an Employer of Record?
An Employer of Record is a third-party company that legally employs your worker on your behalf in countries where you don’t have a legal entity. The EOR:
- Has registered legal entities in dozens or hundreds of countries
- Signs the formal employment contract with your worker
- Runs payroll, withholds taxes, pays statutory benefits and severance
- Handles termination and labor-law compliance
- Charges you a flat monthly fee (typically $400-$700 per employee) plus the gross employment cost
The EOR is not a recruiter. You bring the candidate. You manage the work day-to-day. The EOR is the legal-and-paperwork backbone. If you want the broader EOR overview, our pros and cons of EOR and how to choose an EOR cover the territory.

Why it matters |
|---|---|---|---|
|
Primary service |
Sourcing and placing workers |
Legally employing your hires |
Defines what you’re actually paying for — talent acquisition vs legal employment. |
|
Who finds the candidate? |
The agency |
You (the EOR doesn’t recruit) |
Sourcing markup vs you-bring-the-candidate is the biggest cost lever. |
|
Who’s the legal employer? |
Usually the agency (or worker if 1099) |
The EOR |
The legal employer carries payroll tax, workers’ comp, and termination liability. |
|
Engagement length |
Days to months (typical) |
Months to years (typical) |
Short-term placements suit agencies; long-term hires suit EOR. |
|
Geographic scope |
Usually one country, sometimes regional |
Global, usually 100+ countries |
Global teams need provider coverage in every hire country. |
|
Cost structure |
Markup on hourly rate (30–100%) |
Flat monthly fee + actual gross cost |
Markup compounds monthly; flat fees stabilise — math diverges fast at scale. |
|
Day-to-day control |
Shared — agency may co-manage |
You — full operational control |
Shared control creates joint-employer exposure under US NLRB and IRS rules. |
|
Conversion to direct hire |
Often pricey “buyout” fee |
Direct migration to your entity later, no fee |
Buyout fees on agency conversion often erase the rate savings. |
|
Compliance burden |
Agency carries it for placement period |
EOR carries it for full employment |
Determines whose problem the dismissal lawsuit becomes. |
Who's the Legal Employer? (And Why This Matters)
The “who’s the legal employer” question drives almost everything else.
When the staffing agency is the employer
You direct the work, the agency cuts the paycheck. The worker has a W-2 from the agency, gets benefits through the agency’s plan, and (in most states) workers’ comp coverage through the agency’s policy. If the worker is hurt, sues, or unionizes, it’s primarily the agency’s problem — though “joint employer” doctrine in the US can pull you in too.
This works well when the engagement is genuinely temporary, you don’t want long-term HR responsibility, and the agency has the candidate pool you need.
When you (the client) are the employer
In direct-hire / permanent placement, the agency hands the candidate to your payroll. From day one of employment, the worker is yours — agency takes a one-time fee (typically 15-25% of first-year salary) and exits the relationship. This is what most companies actually want from a staffing agency in a long-term hire scenario.
When the EOR is the employer
The EOR holds the local legal employment. The worker has an EOR-issued contract under their country’s labor law, with all the statutory benefits and protections. You direct the work and integrate them into your team. The EOR runs payroll, taxes, benefits, severance reserves, and termination compliance.
This works well when you want a long-term relationship with a specific person, the person lives in a country where you don’t have an entity, or you want to avoid setting up a foreign subsidiary.
Joint employer risk in all models
In the US, the National Labor Relations Board’s “joint employer” doctrine and the IRS’s economic-reality tests can find that both the staffing agency and the client are employers — exposing the client to wage-hour, unemployment insurance, and unionization risk it thought it had outsourced. EOR engagements abroad don’t usually trigger US joint-employer rules (different jurisdiction), but local labor authorities can still find joint-employer status. A reputable EOR navigates these rules; budget shops sometimes don’t.
True Cost Comparison
Cost depends heavily on the country, the duration, and the worker’s seniority. Some illustrative scenarios.
Scenario A: 6-month US contract software develope
Staffing Agency: Agency bills $150/hour, pays worker $90/hour. Markup = $60/hour ($96K over 6 months at full-time). All-in cost to client: ~$192K. Worker is W-2’d by agency.
EOR: N/A — EOR doesn’t make sense for short-term US-based engagements where the worker would just be a 1099 contractor or W-2 hire.
WINNER: Staffing agency. This is the staffing agency’s home turf.
Scenario B: 2-year senior engineer in Mexico City
Staffing Agency
STAFFING AGENCY: A LATAM-focused IT staffing firm bills $100/hour, pays worker $60/hour. Over 2 years: ~$420K to client, ~$250K to worker.
EOR: Worker’s gross salary equivalent: $90K/year. EOR fee ~$500/month = $6K/year. Mexican employer load (~20%) = $18K/year. Total client cost: ~$114K/year, $228K over 2 years. Worker is properly employed under Mexican labor law with statutory benefits and severance accrual.
WINNER: EOR.~$190K cheaper over 2 years, plus the worker has a real employment relationship that supports retention.
Scenario C: 3-month project requiring 5 designers in 5 countries
STAFFING AGENCY: A boutique global creative agency can do this. Premium markup (~80-100%). Project-shaped, no long-term obligations.
EOR: EORs can employ short-term, but the onboarding overhead is the same as a long-term hire. Diminishing returns under 6 months.
WINNER: Staffing agency. For short-term project work.
Scenario D: Long-term hire of someone you already found
STAFFING AGENCY: Agency-as-employer model is overkill — you don’t need their candidate pool, you’ve already got the candidate.
EOR: Tailor-made for this. You bring the person, EOR handles the legal employment.
WINNER: EOR. This is its core use case.

Speed to Hire
Staffing agencies usually win on raw speed for short engagements: existing pool of pre-screened candidates, standard contracts, no negotiation overhead, and quick onboarding (days, sometimes hours for temp/light-industrial work).
EORs win on speed for long engagements in countries where you’d otherwise need to set up an entity. Entity setup: 3-6 months (Germany), 6-12 months (Brazil), 6+ weeks even in fast jurisdictions. EOR onboarding: 5-15 business days typically. That’s a 4-month-to-2-week speed advantage for
Compliance and Risk
Staffing Agency
If the agency is the W-2 employer, they carry payroll tax remittance, workers’ comp, unemployment insurance, and basic compliance. You still own workplace safety while the worker is on your premises, anti-harassment / EEO compliance, joint-employer exposure (US), and misclassification exposure if the agency uses 1099s.
For 1099-style staffing arrangements in the US, almost all the misclassification risk passes through the agency to you. This has gotten worse since the 2024 DOL final rule. We cover misclassification in detail in our EOR vs Independent Contractor guide.
Employer of Record
The EOR carries the legal employer responsibilities — local labor law, severance, statutory benefits, termination compliance. You retain day-to-day work direction (which is normal for any employee), IP assignment (handled in the EOR’s standard contract), anti-harassment policies, and permanent establishment risk in some countries if the worker triggers local tax presence — manageable with proper structure, see our glossary entry on permanent establishment.
For most international hires, an EOR materially reduces compliance risk vs both the staffing agency model and the “just pay them as a contractor” temptation.
Decision Framework
- Are you hiring for less than 6 months? YES → Staffing agency (or contractor route). NO → Continue.
- Do you have a candidate already, or do you need someone found? Need someone found → Use a recruiter or staffing agency for sourcing. Already have someone → Skip to 3.
- Is the worker in a country where you have a legal entity? YES → Hire them directly onto your payroll (use a recruiter only if you need help finding them). NO → Use an EOR.
- Are you planning 10+ hires in this country in 24 months? YES → Consider setting up your own entity (long-term math). NO → Stay on EOR (short-term math wins).
When to Use Both
It’s not always one or the other. A common pattern is to use a staffing agency or recruiter to source the candidate, pay a one-time placement fee, then hire them via an EOR for long-term employment, statutory compliance, and team membership — and migrate to your own entity once you have 10+ heads in the country.
This is the “best of both worlds” model. The agency does what they’re good at (finding people), the EOR does what it’s good at (employing people in compliance with local law), and you don’t pay either one for the function the other handles better.
