Shared Services vs BPO: Which One Should You Choose?

Choosing between shared services and BPO depends on how you want to manage your business processes. Shared services and BPO can both simplify that complexity, but the right choice depends on how much control, speed, and flexibility you need.

In this guide, we’ll look at the differences between BPO and shared services, where each one fits, and when using both can give you a stronger setup.

What Are Shared Services?

Shared services is an operating model in which a company brings common support functions, such as finance, human resources, IT, and procurement, into one central internal team. Instead of having each department manage the same tasks separately, this team delivers standardized services across the organization. This model helps reduce duplicated work, improve consistency, and maintain greater control over processes and business knowledge.

You'll usually see these functions consolidated first, since they involve high transaction volume and repeatable steps.

What Is Business Process Outsourcing (BPO)?

Business Process Outsourcing (BPO) is a business model where you hire an external service provider to handle specific business processes for you. Instead of building and managing an internal team for that work, you rely on a provider with the staff, skills, systems, and capacity to deliver the process under an agreed contract.

Shared Services vs BPO: What Are the Differences?

You already know that both models exist. The main differences come down to who owns the work, who pays for it, and how much control you keep once it is running. The table below explains the key differences between BPO and shared services side by side, so you can clearly see where each model has an advantage.

When Is a Shared Service the Better Choice?

Shared services can make more sense when you want to keep control of the work while gaining the efficiency of a centralized operation. The model works especially well when your processes have steady demand, require business context, or support capabilities you want to build for the long term.

Here are the situations where shared services can be the stronger fit.

When Is Business Process Outsourcing (BPO) the Better Choice?

BPO can be the stronger option when you need capacity or specialized skills without building an entire operation yourself. It works especially well when your workload changes often, your process follows clear rules, or you need to get the operation running faster.

Here are the situations where BPO can be a better fit.

What Are the Benefits and Challenges of Shared Services vs BPO?

Both Shared services and BPO models can improve how you deliver routine business processes, but they solve different problems. Shared services give you more control and help you build internal capabilities, while BPO gives you faster access to external capacity, skills, and established delivery resources.

The right choice depends on what you need most from the operation and which challenges you are prepared to manage. Here are the main benefits and challenges of each model.

The Hybrid Model: Using Shared Services and BPO Together

Most companies never pick one model and stick with it forever. A hybrid model lets you divide processes based on what needs internal control and what can be handled more efficiently through an external provider.

In a hybrid setup, sensitive, judgment-heavy, or highly regulated processes can stay within your shared services center. Repetitive, high-volume, and well-documented work can move to a BPO provider. This approach gives you greater control over critical processes while creating more flexibility and efficiency for routine work.

Here is how this approach can work in practice.

This split only works if you document and standardize a process first. Sending a messy or undefined process to a provider does not fix it. It only moves the problem outside your walls, where it can be harder to control.

Deloitte's Global Outsourcing Survey found that 78% of companies were already running global in-house centers, while 80% planned to keep or increase their outsourcing spend at the same time. These were not two separate groups competing over which model would win. They were mostly the same companies using both models at once.

Separately, Deloitte's Shared Services data shows that around 65% of companies that build a shared services or GBS setup include outsourcing as part of the same strategy from the start, rather than using it as a fallback plan.

Conclusion

The best delivery model is the one that fits the work you need to get done. Shared services can give you greater control and long-term capability, while BPO can give you speed, flexibility, and access to specialized skills. You can also combine both when different processes need different approaches.

Frequently Asked Questions

Quick answers to the questions people ask most

How do I compare the total cost of shared services and BPO?

Start with the full cost rather than comparing salaries or provider fees alone. Include hiring, technology, facilities, management, training, transition costs, vendor fees, governance, and expected productivity. You should also compare cost per transaction, service quality, capacity utilization, and the cost of scaling or reducing the operation.

What should I consider before outsourcing a shared services process?

You need to assess process maturity, data sensitivity, expected volume, service requirements, and the level of control you need to retain. A well-documented and standardized process is usually easier to transition than work that depends heavily on internal knowledge. You should also define governance, service levels, data controls, transition responsibilities, and the role of your retained team before moving the work.

What is a captive shared services center?

A captive shared services center is an internal delivery operation that you own and control rather than handing the work to an external provider. It can serve multiple business units from one location and centralize functions such as finance, HR, IT, or procurement. A global capability center can operate in a similar way while supporting processes and capabilities across multiple countries or regions.

What is Global Business Services and how does it relate to shared services and BPO?

Global Business Services, or GBS, brings multiple service delivery capabilities under a broader operating structure. It can include shared services, outsourcing, and centers of excellence serving different business units, functions, and regions. This model lets you manage internal and external delivery as part of one broader service network rather than treating shared services and BPO as completely separate choices.

How long does it take to transition a process from shared services to BPO?

The timeline depends on process complexity, documentation, technology, locations, data requirements, and the amount of knowledge transfer involved. A standardized process with clear documentation can usually move more easily than work that depends on specialized internal knowledge. You should also allow time for testing, parallel operations, training, issue resolution, and stabilization before treating the transition as complete.
