What’s the difference between an MSP vs. EOR? Companies are increasingly turning to external partners to manage their contingent, remote and global talent. Two models often come into play in these scenarios: Managed Service Providers (MSPs) and Employers of Record (EORs). While both offer valuable workforce solutions, they serve very different purposes.
What Is an MSP (Managed Service Provider)?
An MSP is an outsourced partner that manages your contingent workforce program end-to-end. This includes temporary staffing, independent contractors and even statement of work (SOW) engagements. The MSP serves as a centralized hub to oversee all aspects of your non-employee labor program.
Key functions of an MSP include:
-
Vendor/supplier management
-
Compliance monitoring
-
Onboarding/offboarding
-
Timecard and invoicing processing
-
Performance metrics and reporting
-
Cost control through rate benchmarking and optimization
-
Integration with a Vendor Management System (VMS)
When to use an MSP:
An MSP is ideal when you’re managing a high volume of temporary or contract labor from multiple staffing vendors. It brings governance, cost savings and efficiency to what can otherwise be a chaotic environment.
What Is an EOR (Employer of Record)?
An EOR is a third-party organization that legally employs workers on your behalf. While the worker reports to you on a day-to-day basis, the EOR handles all employment-related responsibilities including payroll, taxes, benefits and compliance with labor laws.
Key functions of an EOR include:
-
Serving as the legal employer in a specific region or country
-
Managing payroll, tax withholding and benefits administration
-
Ensuring compliance with local labor laws and regulations
-
Handling employment contracts, terminations and risk mitigation
-
Providing work authorization and visa support (in international cases)
When to use an EOR:
An EOR is ideal when you want to hire workers in a location where you don’t have a legal entity, or when you want to reduce the administrative and compliance burden of directly employing workers.
Pros and Cons of Each Model
MSP Pros:
✅ Consolidated vendor management
✅ Cost control and rate optimization
✅ Standardized processes and compliance
✅ Strategic workforce visibility and analytics
MSP Cons:
❌ Doesn’t employ workers directly
❌ Implementation can be complex if no existing VMS
❌ Requires buy-in across multiple departments
EOR Pros:
✅ Hire anywhere without setting up a legal entity
✅ Avoid HR and payroll complexity in new markets
✅ Reduce legal risk and noncompliance exposure
✅ Fast and scalable international expansion
EOR Cons:
❌ Less control over employment details in some regions
❌ Not ideal for high-volume contingent labor
❌ Can be more expensive on a per-worker basis
MSP vs. EOR – Which Do You Need?
In some cases, companies may need both services, especially if they manage a large contingent workforce in multiple geographies. For example, your MSP may manage your entire vendor base and staffing program, while your EOR employs specific remote workers in countries where you don’t have a legal presence.
Ask yourself:
-
Are you managing hundreds of temps or contractors from multiple staffing firms? → MSP
-
Are you hiring a full-time remote worker in Germany, but have no entity there? → EOR
-
Do you need a streamlined, compliant program with centralized oversight? → MSP
-
Do you want to test a new international market without establishing a local branch? → EOR
-
Are you scaling fast and need both contingent labor and remote full-time hires? → Possibly both
How This Impacts Compliance
Misclassifying workers is a major legal and financial risk, especially with growing scrutiny from governments. Whether it’s the IRS in the U.S. or local labor authorities abroad, companies must be precise in how they engage workers.
A reputable MSP will help ensure that vendors are classifying workers correctly and complying with labor laws. An EOR acts as the employer of record, reducing misclassification risk entirely by legally hiring the worker and assuming employment responsibility.

Know Your Model Before You Scale
Understanding the differences between an MSP vs. EOR is vital for any business looking to grow its workforce across functions, geographies, or employment types. Whether you’re aiming for cost control, global reach, or compliance peace of mind, the right model (or combination of models) will ensure you scale responsibly and sustainably.
