When companies face growing pressure to scale teams quickly, two outsourcing models often come into play: Recruitment Process Outsourcing (RPO) and Managed Service Providers (MSP).
While both promise to streamline hiring, they serve fundamentally different purposes — and confusing one for the other can derail your entire workforce strategy.
According to Staffing Industry Analysts (SIA), the global RPO market grew by 18% in 2023, while MSP programs expanded 12%, highlighting the rising but distinct demand for each model.
Yet many organizations still treat them interchangeably — often leading to mismatched outcomes and missed growth opportunities. That is why understanding the difference between RPO and MSP is crucial to optimize your hiring process.
In this guide, we’ll break down exactly how RPO and MSP differ, when to use each model, and how to align the right solution with your company’s hiring goals.
Understanding RPO and MSP
Recruitment Process Outsourcing (RPO)
Recruitment Process Outsourcing (RPO) is when a company partners with an external provider to handle all or part of its permanent recruitment process. Instead of just helping with hiring here and there, RPO providers take real ownership—offering a strategic, end-to-end hiring solution that’s tailored to the business’s unique needs.
Managed Service Provider (MSP)
A Managed Service Provider (MSP) is a partner that oversees and optimizes an organization’s entire contingent workforce program. Rather than focusing on permanent hiring, MSPs manage temporary workers, independent contractors, freelancers, and consultants—helping companies stay agile while keeping operations compliant and cost-effective.
Key Differences Between RPO and MSP
Scope
RPO:
An RPO provider acts as a true extension of your internal HR or talent acquisition team. They manage everything from building talent pipelines, sourcing passive candidates, conducting initial screenings, to even supporting interview coordination and onboarding.
MSP:
An MSP coordinates with multiple staffing agencies (often called suppliers), negotiates contracts, ensures policy compliance, monitors performance metrics, and manages billing and invoicing.
Workforce Focus
RPO:
Recruitment Process Outsourcing (RPO) focuses on hiring permanent, full-time employees. RPO providers act as an extension of your internal HR team, ensuring candidates are sourced, screened, and onboarded to contribute to long-term organizational growth.
MSP:
Managed Service Providers (MSP) specialize in contingent workforce management, handling temporary, contract, freelance, or project-based talent. Their goal is to optimize the flexibility and compliance of your non-permanent staffing.
Sourcing Approach
RPO:
An RPO provider leverages direct sourcing methods such as headhunting, strategic advertising, talent mapping, and pipeline building. They maintain dedicated talent pools aligned with your brand’s values and hiring needs.
MSP:
MSPs rely on indirect sourcing by coordinating with multiple third-party staffing vendors. They act as an intermediary, streamlining vendor relationships and ensuring efficient delivery of contingent talent.
Technology Used
RPO:
RPO solutions typically integrate an Applicant Tracking System (ATS) into your hiring operations. This helps manage the full lifecycle of permanent candidates, from application to onboarding, with a focus on data-driven hiring decisions.
MSP:
MSPs operate through Vendor Management Systems (VMS), built to oversee multiple staffing suppliers, track contingent worker performance, and maintain compliance at every engagement point.
Integration Level
RPO:
An RPO provider becomes deeply embedded within your HR function, often sharing KPIs, employer branding initiatives, and workforce planning strategies. They act as an in-house partner rather than an external vendor.
MSP:
An MSP maintains a more external, governance-focused role. While highly collaborative, they usually operate independently from HR, focusing instead on vendor management, contract negotiations, and operational efficiency.
Primary Objective
RPO:
The core mission of RPO is to enhance the quality of permanent hires. They invest time in understanding your culture, forecasting hiring needs, and building sustainable talent pipelines that fuel business growth.
MSP:
An MSP’s primary goal is to optimize the management of contingent labor. They prioritize vendor performance, cost containment, compliance, and rapid scalability of non-permanent workforce solutions.

Choosing Between RPO and MSP
Hiring Needs:
- If your organization’s priority is scaling permanent, full-time hiring, an RPO is the better fit.
- If you need to manage a high volume of temporary, contract, or freelance workers, an MSP will provide better structure and efficiency.
Internal Resources:
- Companies with limited or overstretched internal recruitment teams can benefit from RPO providers acting as an embedded extension of HR.
- Organizations already dealing with multiple staffing vendors — but struggling to maintain efficiency — can leverage an MSP to centralize and optimize vendor relationships.
Compliance Requirements:
- If your workforce spans multiple states, regions, or countries, an MSP ensures better compliance with varying labor laws, tax regulations, and contractual standards.
- For organizations hiring primarily in one country with simpler compliance needs, RPO remains focused on hiring quality rather than broad legal oversight.
Budget Constraints:
- RPOs typically charge based on cost-per-hire or fixed fees, making them ideal if you plan to ramp up full-time hiring efficiently.
- MSPs help control the cost of contingent labor by negotiating vendor rates, reducing rogue spending, and consolidating invoicing across agencies.
Pro Tip:
Many growing companies don’t have to choose only one. It’s common for organizations to use RPO for permanent hiring while partnering with an MSP for contingent workforce management at the same time.
This hybrid approach gives businesses the best of both worlds: quality permanent hires to fuel long-term growth, and flexible contract talent to stay agile in shifting markets.
Conclusion
Choosing between RPO and MSP comes down to the type of workforce you need to build — and how you want to manage it.
If you’re aiming to strengthen your core team with high-quality, permanent employees, partnering with an RPO provider is the way to go. They’ll integrate into your talent acquisition strategy, focus on culture fit, and help drive long-term organizational growth.
On the other hand, if your business relies heavily on temporary talent, freelancers, or contractors across multiple projects or regions, an MSP will centralize that complexity. You’ll gain better vendor control, compliance assurance, and cost visibility — all essential when managing a flexible workforce at scale.
Both models offer huge advantages when aligned with the right business goals. The risk lies not in choosing either RPO or MSP, but in choosing the wrong one for the challenges you actually face.
FAQs
What is the main difference between RPO and MSP?
The key difference lies in the type of workforce they manage. RPO focuses on permanent, full-time hiring by acting as an extension of a company’s internal recruitment team. MSP, on the other hand, manages a company’s contingent workforce — including freelancers, contractors, and temporary staff — by coordinating multiple staffing vendors.
Can a company use both RPO and MSP at the same time?
Yes, absolutely. Many companies use RPO services for their permanent hiring needs while simultaneously working with an MSP to manage their contingent labor. This hybrid approach offers flexibility and helps optimize both full-time and project-based hiring strategies.
How do RPO providers typically charge for their services?
RPO providers usually charge based on a cost-per-hire model, monthly management fees, or a combination of both. Some also offer flexible pricing structures depending on hiring volumes, roles, and regions, making it easier for companies to scale recruitment efforts as needed.
When is it better to choose an MSP over an RPO?
If your organization heavily depends on temporary staff, contractors, or consultants — especially across multiple vendors or locations — an MSP is the better fit. MSPs specialize in optimizing vendor relationships, improving compliance, controlling costs, and providing visibility across your contingent workforce.
