How is recruitment process outsourcing (RPO) different from body leasing?

Definitions of RPO and Body Leasing

Recruitment Process Outsourcing (RPO) and body leasing are two distinct models for supporting companies in the areas of human resources and IT. Both deal with talent acquisition, but they operate in fundamentally different ways.

RPO involves outsourcing all or part of a company’s recruitment processes to an external provider. The RPO provider acts as an extension of the client’s HR department, taking responsibility for managing the entire recruitment process — from candidate sourcing through selection to onboarding — with the goal of hiring employees for permanent positions with the client organization.

Body leasing is a model for temporarily engaging IT professionals for a specific period of time. These specialists work at and for the client but are not the client’s permanent employees. They remain contractually bound to the body leasing provider or operate on a B2B (freelance) basis.

Purpose and Object of the Service

RPO — Recruitment Optimization

The primary objective of RPO is to optimize and professionalize the process of hiring permanent employees for the client. The RPO provider focuses on:

• Improving the quality of hires through systematic assessment processes and data-driven candidate evaluation
• Reducing time-to-hire through more efficient sourcing strategies and process automation
• Lowering cost-per-hire through economies of scale and optimized workflows
• Building sustainable talent pipelines for recurring hiring needs
• Strengthening the employer brand on the talent market through consistent candidate experience

The object of the service is managing the recruitment process itself — not providing a workforce.

Body Leasing — Flexible Competency Provision

The purpose of body leasing is to quickly and flexibly provide the client with needed IT competencies for a specific period, without the requirement for permanent hiring. This enables:

• Immediate access to specialized skills not available internally
• Scaling team capacity according to project demand
• Bridging temporary gaps in ongoing projects
• Flexibility in adapting team composition to changing requirements

The object of the service is the temporary provision of specific specialists’ work.

Form of Employment of Acquired Individuals

This is the most fundamental difference between the two models and carries far-reaching legal and practical consequences:

In the RPO model, the result of the provider’s work is the candidate being hired on a permanent basis directly by the client company. The candidate receives an employment contract from the client and becomes their employee. The RPO provider does not employ these individuals — their service concludes with the successful filling of the position.

In the body leasing model, the specialists do not become employees of the client. They remain contractually bound to the body leasing provider (through an employment contract or B2B agreement) and are only temporarily assigned to work for the client. The client pays the provider, not the specialist directly.

Aspect	RPO	Body Leasing
Specialist’s contract	Directly with the client (permanent)	With the provider or B2B
Payroll	Client	Provider
Social security	Client	Provider or self-employed
Employment protection	Client’s labor law	Contract-dependent
Long-term binding	Permanently intended	Temporary

Accountability and Engagement Model

RPO providers take responsibility for the efficiency and results of the recruitment process according to established performance indicators. Typical KPIs include:

• Time-to-hire (duration from requisition opening to offer acceptance)
• Quality-of-hire (performance and retention of placed candidates)
• Candidate satisfaction score
• Offer acceptance rate
• Cost-per-hire
• Retention rate at 6 and 12 months

The RPO provider works in close cooperation with the client’s HR department and hiring managers. They integrate into internal processes, often use the client’s Applicant Tracking System (ATS), and represent the employer brand externally.

Body leasing providers are primarily responsible for supplying specialists with the agreed competencies and ensuring service continuity. The day-to-day management and direction of the specialist’s work lies with the client. The provider handles administrative aspects such as contract management, payroll processing, and compliance.

Time Perspective and Strategic Alignment

RPO is typically a long-term solution designed to strategically improve an organization’s recruitment function. RPO engagements commonly run for two to five years and aim to transform the client’s entire recruitment infrastructure. There is also project-based RPO for specific campaigns or phases with high hiring volumes, such as rapid scaling of a new development center.

Body leasing is often used as a more tactical solution, addressing current, frequently temporary project needs or competency gaps. Engagements can range from a few months to several years but are fundamentally designed as time-limited arrangements.

Cost Structure and Billing Model

The cost structures of both models differ considerably:

RPO cost models:

• Management fee: Monthly charge for process management and operations
• Cost-per-hire: Fee for each successful placement
• Hybrid model: Combination of management fee and success-based component
• Total costs typically decrease as hiring volume increases due to economies of scale

Body leasing cost models:

• Daily rate or hourly rate for the provided specialist
• Monthly flat fee based on agreed availability
• The rate encompasses the provider’s margin, salary costs, and administrative overhead
• Costs scale linearly with the number of specialists provided

When to Choose RPO and When to Choose Body Leasing

A company should consider RPO when:

• It wants to professionalize and scale its internal recruitment processes
• High hiring volumes need to be managed (more than 50 positions per year)
• The internal HR department needs to be freed up to focus on strategic tasks such as talent development and retention
• The quality of hires needs systematic improvement across the organization
• Employer branding and candidate experience need to be enhanced to compete for talent

A company should consider body leasing when:

• Quick access to IT professionals is needed for a limited time
• Specific technical competencies are required for particular projects
• Increasing permanent headcount should be avoided for budgetary or strategic reasons
• Flexibility in team composition is desired to respond to shifting project demands
• Competencies are needed that the organization does not plan to build internally on a permanent basis

Combining Both Models

In practice, many companies deploy both models in parallel. RPO is used to optimize long-term talent acquisition and build a sustainable hiring engine, while body leasing covers short-term peak demands and specialized project needs. This combination enables a holistic workforce strategy that addresses both strategic and tactical requirements, ensuring that permanent positions are filled efficiently while project-based needs are met with agility.

Regulatory Considerations

Both models carry distinct regulatory implications that organizations must understand:

• RPO is generally less regulated since the end result is a standard employment relationship between the client and the candidate. However, data privacy regulations (such as GDPR) apply to candidate data handling.
• Body leasing is subject to temporary employment regulations in many jurisdictions. In the European Union, the Temporary Agency Work Directive establishes equal treatment principles. In Poland, the Act on Employment of Temporary Workers defines maximum assignment durations and worker rights. Companies must ensure compliance to avoid reclassification risks.

Summary

RPO and body leasing are two fundamentally different solutions that address distinct talent acquisition needs. RPO focuses on optimizing the recruitment of permanent employees for the client, transforming the entire hiring function into a strategic asset. Body leasing provides flexible access to the competencies of IT professionals on a temporary basis, without long-term employment commitments. The most essential difference lies in the employment form: RPO leads to permanent hiring by the client, while body leasing involves the temporary provision of external specialists. The choice between the two depends on a company’s strategic goals, the nature of its staffing needs, and the desired level of flexibility. Many organizations benefit from deploying both approaches complementarily, building a comprehensive workforce strategy that combines permanent hiring excellence with on-demand access to specialized talent.
