Master Vendor vs. Neutral Vendor: Workforce Management Models Explained
In today’s digital, globalised, and highly competitive economy, businesses must concentrate on their core activities. Consequently, many functions are increasingly being outsourced, including accounting, payroll, IT, and even recruitment and contingent workforce management. If terms like “Master Vendor,” “Neutral Vendor,” or “Business Process Outsourcing” seem confusing, don’t worry; we’ll clarify them for you!
The job market is rapidly evolving, presenting new avenues for companies to acquire talent. These methods, all involving a third-party service provider, may prove valuable for professions facing candidate shortages and for companies with frequent and regular temporary labour needs.

Some key definitions:
- Business Process Outsourcing (BPO): Outsourcing certain business processes, such as procurement, accounting, IT, or recruitment, to a third-party company. This allows businesses to concentrate more fully on their main operations.
- Recruitment Process Outsourcing (RPO): Partial or total outsourcing of recruitment activities. RPO is particularly beneficial when large recruitment volumes are involved. A dedicated team carries out recruitment activities directly on behalf of the client, often onsite.
- Managed Service Provider (MSP): An external organisation that assumes primary responsibility for managing an organisation’s contingent workforce, overseeing tasks such as supplier engagement, recruitment processes, and compliance monitoring. This approach suits companies regularly employing numerous short-term workers from multiple staffing agencies, transferring responsibility to a third-party recruitment specialist.
- Neutral Vendor: This involves utilising a managed service provider (MSP) who specialises in recruitment but remains independent of staffing agencies to manage temporary staff resources. The Neutral Vendor model is the most common MSP type, accounting for 55% of managed services globally (measured by total spend). This service is frequently delivered through subsidiaries of recruitment and temporary work solution providers, emphasising the importance of independence and neutrality in relation to suppliers. Consequently, there should be no conflict of interest between the neutral vendor and the client’s partner agencies. The neutral vendor centralises the client’s needs and manages suppliers to identify the most suitable candidates for assignments, under optimal financial conditions. Similar to the Master Vendor, the Neutral Vendor also monitors the service quality of each provider and ensures adherence to processes by all parties involved. Benefit: Ensures impartiality and access to a wider pool of candidates.
- Master Vendor Programme (MVP): A managed service model where one main supplier, the ‘Master Vendor’, coordinates contingent workforce supply through multiple staffing suppliers, including itself. This approach represents around 25% of managed service spend globally. A Master Vendor will manage the entire process of recruiting and integrating temporary workers, from selection to off-boarding, covering onboarding, training, and activity monitoring. They may also select suppliers, negotiate terms, and handle payments to sub-suppliers on the customer’s behalf, as well as monitor the service quality provided by each supplier. Its central position and process control enable the establishment of precise Key Performance Indicators (KPIs). Benefit: Single point of contact for streamlined management.
Regional Interpretations:
While organisations like Staffing Industry Analysts (SIA) classify both Master Vendor and Neutral Vendor as MSP models, regional interpretations may vary. For instance, in some European countries, the Master Vendor model might not be traditionally viewed as an MSP due to specific legal and operational frameworks.
Emphasising Flexibility in Terminology:
It’s important to recognise that the classification of these models can differ based on organisational practices and regional norms. Therefore, when discussing or implementing these models, it’s advisable to consider the specific context and definitions prevalent in your organisation’s operating regions.
The situation across Europe
Across Europe, Managed service solutions vary due to differing legal frameworks. For instance, arrangements where a Master Vendor supplies labour directly alongside secondary suppliers are prohibited in some countries, including France and Italy, due to legal restrictions against outsourcing personnel procurement. In contrast, Neutral Vendor models have become well-established in highly regulated markets with significant temporary workforce demands, such as automotive, pharmaceutical, and financial services sectors. Countries like Germany also enforce strict licensing regulations preventing staffing providers from operating in contractual chains, making the Neutral Vendor model preferable.
Some managed service providers deliver programs internationally, supporting organisations across their subsidiaries by adapting supplier strategies to local conditions and leveraging global partners. These providers ensure cost optimisation, process standardisation, and consolidated information at the head office level. In some instances, service providers may further integrate into the customer’s value chain by combining permanent staff recruitment (RPO) with flexible resource recruitment, temporary staff (MSP / Neutral Vendor), freelancers, consultants, and internal training programs, sometimes referred to as Total Talent Acquisition (TTA) or Total Talent Management (TTM).
