RPO stands for Recruitment Process Outsourcing. It is where an organisation hands some or all of its recruitment over to an external provider, who then runs that hiring on the organisation’s behalf and usually behind its brand. RPO can cover the whole hiring lifecycle or one part of it, and can run permanently, for a fixed project or on demand.
RPO in recruitment means Recruitment Process Outsourcing. It’s where some, or all of a recruitment process is outsourced.
Recruitment Process Outsourcing (RPO) is a form of business process outsourcing where an employer transfers all or part of its recruitment processes to an external RPO service provider. An RPO provider acts as an extension of a company’s HR and Talent function to provide an efficient, effective, and scalable recruitment function.
Unlike traditional recruiting or staffing agencies that focus on filling individual positions and are more transactional, RPO companies offer a more strategic approach. They can manage the entire recruitment process, from job profiling and candidate sourcing to interviewing and onboarding, often using their own technology, multi-channel sourcing strategies, networks and expertise to optimise the hiring process. Most RPO providers will operate behind your brand to promote your Employer Value Proposition and ensure that they attract the right talent for your organisation at the right time – leaving you to focus efforts elsewhere in the business.
Put simply, an agency sells you candidates. An RPO provider like ourselves runs your talent function. That difference in scope is what changes the commercial model, the reporting and the level of control you keep.
Every RPO engagement is shaped around the client, but almost all of them move through the same five stages. What changes is the depth of each stage and who owns it. A high volume project spends most of its effort on attraction and selection, while a full end-to-end service puts far more weight on design and mobilisation at the start. The typical five stages we see are:
Most people searching for what RPO means are really trying to work out how it differs from the two models they already know. This is the fastest way to see it:
| RPO | Recruitment agency | In-house team | |
|---|---|---|---|
| What are you buying | A recruitment function | Individual capabilities | Permanent headcount |
| Scope | All or part of the hiring process, end to end | Sourcing and shortlisting for a specific vacancy | Whatever your team has capacity for |
| Commercial model | Management fee plus reduced placement fees or a fixed fee per recruiter | Percentage of first year salary per placement, typically 15% to 30% | Fixed salary cost regardless of hiring volume |
| Whose brand | Yours. The provider works behind your employer brand | Usually the agency's | Yours |
| Flexes with demand | Yes, up and down | Yes, but cost rises with every hire | Slowly, and usually at the wrong moment |
| Best suited to | Organisations with ongoing, variable or high volume hiring who want process, data and cost control | Occasional or one-off niche hires | Steady, predictable hiring volumes |
For a fuller comparison, read our guide to the difference between RPO and recruitment agencies.
Organisations consider RPO services for several compelling reasons:
RPO services can significantly reduce costs by streamlining processes and leveraging economies of scale. RPO companies already have the right tech, the engaged networks and the expertise to source the best talent in hard-to-reach places. Internal Talent Acquisition functions don’t always have the budget, time or know-how to source the right candidates in skills-short markets. Partnering with an RPO company can enhance your recruitment processes without you having to invest in expensive tech and networks.

RPO providers can quickly scale recruitment efforts up or down based on your hiring needs. When an organisation needs to ramp up hiring – for example during mergers, acquisitions, seasonal surges, or large-scale projects – RPO providers can quickly mobilise extra resources. They have access to established talent pools, robust recruitment technology, and expert teams to handle high volumes of candidates efficiently. This ability to scale eliminates the need for organisations to allocate internal resources to manage temporary hiring spikes.
Most RPO providers will operate behind your brand to promote your Employer Value Proposition and ensure that they attract the right talent for your organisation at the right time – leaving you to focus efforts elsewhere in the business.
RPO providers bring specialist recruitment knowledge and best practices to your organisation.
RPO providers are equipped with specialised expertise, technology and resources that in-house teams may lack. By combining data analytics with structured, human-led screening, they can more consistently identify high-quality candidates. Their ability to tap into broader talent pools – through passive candidate searches, social platforms, and wide-reaching recruitment networks – ensures a selection of qualified applicants. Furthermore, RPOs often implement structured assessment techniques, including behavioural interviews, psychometric testing, and skill evaluations, to ensure that candidates not only possess the required technical qualifications but also align culturally with the organisation. Omni’s Talent Strategy team are experts in assessment and training.
Additionally, their continuous engagement with talent markets allows them to stay updated on the latest hiring trends, emerging skill sets, and industry-specific needs.
RPO services can significantly decrease the time it takes to fill positions. Omni is an award-winning RPO provider with proven success in reducing time-to-hire. Our case studies speak for themselves.
We reduced time-to-hire by 68% for London Gatwick, one of the UK’s busiest transport hubs, across hard-to-fill Commercial, Planning and Design roles. Before the partnership, fewer than half of submitted CVs were reaching the interview stage. Afterwards, 88% did and 56% of interviewed candidates went on to receive an offer. Taking recruitment advertising in-house to Omni generated three times more applications, and up to seven times more for some roles.
“Through 2024 as a collaborative team, we made radical improvements to ways of working… which has resulted in a notable increase in the quality of candidates, significant reduction in the time-to-hire and achieving huge gains in hiring manager satisfaction.” Kelly Robinson, Talent Acquisition Manager, London Gatwick.

Outsourced recruitment providers ensure that recruitment processes comply with all legal and regulatory standards. These include local labour laws, data protection regulations, and equal opportunities legislation.
RPO service providers ensure adherence to industry-specific regulations including background checks in regulated environments, such as health and safety in construction . Their standardised processes help reduce the risks of non-compliance, penalties, or reputational damage.
Outsourcing recruitment to an RPO company allows internal HR teams to concentrate on high-value strategic initiatives that directly impact business growth. These initiatives include employee engagement, leadership development, organisational culture, and succession planning. Instead of dedicating time and resources to the tactical aspects of hiring – such as sourcing, screening, and interviewing – HR teams can focus on fostering employee satisfaction, improving retention, and developing training programmes that enhance workforce skills.

RPO services are not one-size-fits-all. There are several models to choose from:
End-to-End RPO involves outsourcing the full recruitment lifecycle, from sourcing and screening to interviewing and onboarding. It allows companies to streamline hiring by using the RPO provider’s expertise, technology, and data-driven insights. The main benefit is consistency and scalability, ensuring that hiring processes are standardised and can easily adjust to changing needs. By handling the entire recruitment function, companies save valuable time, reduce costs, and gain access to a broader talent pool, all while focusing on their core operations. This model is ideal for organisations seeking a comprehensive and ongoing talent acquisition strategy.
Project RPO is a short-term recruitment solution designed to manage hiring for a defined period or specific project. It’s ideal for businesses with seasonal peaks, new product launches, or expansion into new markets. One of the key benefits is its flexibility – employers can scale recruitment efforts up or down based on immediate needs without long-term commitments. The RPO provider quickly mobilises resources, helping to manage high-volume hiring efficiently. By outsourcing recruitment for time-sensitive projects, internal teams can focus on other priorities, ensuring business continuity. Project RPO also offers many benefits including cost savings, as companies only pay for services when needed, while accessing specialised recruitment expertise and broader candidate networks.
On-Demand RPO recruitment offers flexible recruitment support when businesses face fluctuating hiring demands or urgent vacancies. This model allows companies to engage RPO providers on an as-needed basis without long-term contracts, providing cost-efficiency and agility. Benefits include immediate access to the RPO provider’s recruitment technology, candidate networks, and experienced recruiters, speeding up the hiring process. On-Demand RPO is particularly useful during periods of rapid growth, business transitions, or short-term recruitment challenges. The flexibility of On-Demand RPO recruitment helps organisations stay agile, responding to changing workforce needs without disrupting ongoing operations.
Hybrid RPO, sometimes called selective RPO, is where a provider takes on specific parts of the recruitment process while your internal team keeps the rest. A common split is the provider handling attraction, sourcing and screening while hiring managers and internal TA retain interviewing and final selection. It suits organisations that have a capable internal team but a bottleneck is one part of the process, and it is often the sensible first step for an organisation that is not ready to outsource its whole function.
At Omni we don’t sell hybrid RPO as a separate product. We’ve built that flexibility into our End-to-End RPO and Project RPO services instead, so you can hand over as much or as little of the process as you need and change the split as your hiring does. You get the same selective approach without having to commit to a different model or renegotiate when your requirements shift.

Read Case StudyThe cost of RPO services varies and is dependent on several factors. There are also different pricing models that can be adjusted to an organisation’s specific requirements. Commonly, commercial models underpinning RPO recruitment include some combination of the following:
This is a one-off-charge and likely to be used when there is a significant amount of work to be undertaken to set-up the service e.g., Process mapping, introducing new technology (Including training end-users), transferring services from previous providers etc. If it is straightforward then it is unlikely to apply.
Often providers will set a small monthly management fee for the duration of the contract which will help off-set some direct delivery costs, particularly if recruitment volumes are uncertain and the provider may be left with costs that are difficult to recover through placement fees alone. Whilst any commercial risk remains weighted heavily towards the provider, this arrangement reflects a shared responsibility which is fundamental if RPO is to work for your business.
This is where most costs sit and only applies when people start in the role. Within an RPO service, where a management fee is in place, these placement fees are substantially reduced, with many offered as a fixed-fee or single figure percentage of the annual salary. Most cost coverage and any profit for the RPO company depends on making placements – so they must perform!
Subject to requirements, alternative commercial arrangements may include a fixed-fee per month/per recruiter which can lend itself to On-demand RPO where support scales up and down quickly.
When it comes to a ‘per-hire’ cost comparison, RPO invariably provides significantly greater value for money than more transactional recruitment agency services, whilst at the same time delivering process efficiencies and brand value. In many instances, RPO delivery is comparable to in-house recruitment models, but has the significant advantage of flexibility and scale which internal TA functions struggle to replicate at pace.
RPO is not the right answer for everyone, and any provider who tells you otherwise is selling rather than advising. What decides it is rarely the size of your organisation. It comes down to your hiring pattern, how much of your current process is already working and whether the problem you have is actually a recruitment problem in the first place.
RPO usually works well when:
RPO is usually the wrong answer when:
AI now sits inside most recruitment technology, which makes it a fair question to ask any RPO provider. Omni’s position is that AI supports our recruiters, it does not replace their judgement. We use technology to reduce administrative load, improve sourcing reach and surface better data. We do not use AI to screen, assess or select candidates. Those decisions are made by people, against a structured and consistent process, because that is what protects both hiring quality and candidates being treated fairly.
If you have read this far, you are probably weighing RPO against carrying on as you are. The useful next step is not a proposal, it is a number. Work out what your current recruitment actually costs using our recruitment cost calculator, then compare it against the model that fits your hiring pattern, whether that is end-to-end RPO, on-demand RPO or project RPO. If you would rather talk it through first we are happy to do that with no obligation.
RPO, or Recruitment Process Outsourcing, is a strategic approach to talent acquisition where organisations outsource some or all of their recruitment processes to an external provider.
In traditional hiring, organisations typically manage recruitment processes in-house, from sourcing candidates to onboarding. This often requires significant time, resources, and expertise from internal HR teams or hiring managers. However, traditional hiring methods can sometimes struggle to keep pace with changing talent demands, especially in industries facing skill shortages or rapid growth.
RPO offers a holistic and strategic approach to talent acquisition. RPO providers like Omni act as an extension of an organisations brand, assuming responsibility for recruitment activities such as candidate attraction, sourcing, screening, assessment, and even onboarding. By outsourcing these functions to specialised experts, organisations can benefit from industry knowledge, resources, and technology to give access to the best talent at pace.
One of the key differences between RPO and traditional hiring lies in the level of specialisation and scalability offered by recruitment RPO providers. RPO partners often have dedicated teams of recruiters who specialise in specific industries or skill sets, allowing them to access niche talent pools and identify high-quality candidates more efficiently. Additionally, RPO solutions are highly scalable, meaning they can quickly adapt to fluctuating hiring needs, whether it’s scaling up recruitment efforts during peak periods or adjusting to changing market conditions.
Recruitment Process Outsourcing (RPO) can significantly enhance your Talent Acquisition strategy by providing specialised expertise, scalability, and strategic partnership. Here’s how:
Specialised Expertise: RPO providers have dedicated teams of recruiters who specialise in various industries, roles, and skill sets. These experts possess in-depth knowledge of the labour market, industry trends, and sourcing techniques, allowing them to identify and attract high-quality candidates efficiently. By leveraging their specialised expertise, RPO partners, like Omni, can access niche talent pools and ensure high-quality people for your organisation.
Scalability: One of the key advantages of recruitment RPO is its scalability. RPO providers can quickly scale recruitment efforts up or down based on your organisation’s hiring needs. Whether you’re experiencing rapid growth, seasonal fluctuations, or project-based hiring spikes, RPO can adapt to accommodate your changing requirements. This flexibility ensures that you have the right resources in place to meet demand without overburdening your internal HR team or sacrificing recruitment quality.
Cost-Effectiveness: RPO recruitment can offer cost savings when compared to traditional hiring methods. While there may be an initial investment in outsourcing recruitment to an RPO partner, the long-term benefits often outweigh the costs. RPO can help reduce time-to-fill, cost-per-hire, and turnover rates, resulting in overall cost savings for your organisation.
Strategic Partnership: RPO goes beyond transactional recruiting by forging a strategic partnership between the RPO partner, like Omni, and your organisation. At Omni, we become an extension of your employer brand and we work closely to understand business objectives, culture, and talent requirements. This collaborative approach allows RPOs to tailor recruitment strategies that align with your organisation’s goals. By working as an extension of your HR team, RPO providers can provide valuable insights, leading practices, and innovative solutions to help achieve talent acquisition objectives.
There are several key advantages:
Access to Specialised Expertise: RPO providers have dedicated teams of recruiters who specialise in various industries, roles, and skill sets. This expertise allows them to identify and attract high-calibre talent more efficiently than internal HR teams or traditional recruitment agencies.
Scalability: RPO recruitment solutions are highly scalable, meaning they can quickly adapt to fluctuating hiring needs. Whether your organisation is experiencing rapid growth, seasonal fluctuations, or project-based hiring spikes, RPO can flexibly adjust to accommodate your changing requirements.
Cost Savings: RPO can offer cost savings compared to traditional hiring methods. By outsourcing recruitment processes to an external provider, organisations can reduce time-to-fill, cost-per-hire, and turnover rates, resulting in overall cost savings for the business.
Strategic Partnership: RPO recruitment goes beyond transactional recruiting by fostering a strategic partnership between the RPO provider and the organisation. At Omni, we work closely with our organisations to understand their organisation’s objectives, culture, and talent requirements, allowing us to tailor recruitment strategies that align with the organisation’s goals and values.

Recruitment Process Outsourcing (RPO) is a strategic approach to talent acquisition where organisations outsource some or all of their recruitment processes to an external provider, like Omni. The partner is known as the RPO provider and assumes responsibility for various aspects of the recruitment process, including candidate attraction, candidate sourcing, screening, assessments, interview coordination and onboarding.
Recruitment RPO is about leveraging specialised expertise, technology, and resources to streamline the recruitment process and improve hiring outcomes. Rather than relying solely on internal HR teams or traditional recruitment agencies, organisations partner with RPO providers to access a broader range of talent to enhance efficiency and drive better results.
The specific services offered by RPO providers can vary depending on the needs and preferences of the organisation. That’s the beauty of RPO. Some organisations may opt for end-to-end RPO, where the RPO provider manages the entire recruitment process from start to finish. Others may choose to outsource specific elements of the recruitment process, such as candidate sourcing or interview scheduling, while retaining other aspects.
