The difference between BPO and call center models comes down to scope.
A call center handles inbound and outbound calls and other customer communication. Business Process Outsourcing Services (BPO) hand a wider mix of front-office and back-office work, from support to payroll, to a third-party provider.
For a scaling business, picking the wrong model means paying for services it doesn’t need or managing more vendors than necessary.
What Is BPO vs. What Is a Call Center?
So, what is BPO and call center work in practice?
What BPO means
As for What Is Business Process Outsourcing, BPO means contracting an external provider to run business processes such as accounting, HR, IT, billing and Outsourced Customer Service.
It’s a large industry, worth about $415.73 billion according to Statista figures cited by Giva.
What a call center means
A call center manages customer conversations, traditionally by phone. Many now also handle email, chat, SMS and social media, which is why the term “contact center” has become common.
A call center can be in-house or outsourced, but BPO always involves an outside partner.
Key Differences Between BPO and Call Centers
The main BPO and call center difference is the scope of services, but scope isn’t the only difference. The two models also differ in ownership, flexibility and scalability, specialization, and cost structure.
A simple way to separate them is that BPO is defined by who does the work, a third-party partner. A call center is defined by what the work is, which is customer conversations.
The two blur when a provider runs a BPO call center that handles phone support alongside back-office tasks. The five areas below work like a side-by-side comparison table.
Business Goals
BPO goals
BPO goals cover the whole business. They include focusing on core competencies, gaining expertise, improving efficiency and growing over time.
Deloitte’s 2024 Global Outsourcing Survey, cited by Unity Communications, found that access to talent is now the top reason companies outsource, at 42%. Cost reduction came second at 34%.
Call center goals
Call center goals are narrower and tied to one function, such as raising customer satisfaction (CSAT), boosting sales conversions or collecting overdue payments.
A quick test
A quick test helps here. If a goal names a single metric, it belongs to a call center. If it describes how the company runs, it belongs to BPO.
Level of Involvement
How BPO works with you
BPO always works as a partnership. The provider runs processes under a contract and a service-level agreement (SLA) and handles hiring and training.
It often adopts your tools, workflows and metrics, so it acts as an extension of your team. These are usually long-term relationships, and BPO managers often take part in planning.
How a call center works with you
A call center gives you a choice. You can run it in-house with full control, or outsource it to a vendor that specializes in high call volumes.
A call center connected to CRM tools and centralized reporting can offer more than basic phone support.
Nature of Services
This is where the two models differ most.
BPO services
BPO covers front-office work such as customer support, sales and live chat. It also covers back-office work such as accounting, payroll, HR, data entry and inventory management.
Deloitte’s survey found that 56% of organizations now outsource front-office functions.
Call center services
A call center sticks to customer conversations:
- Inbound calls cover support, troubleshooting and order questions.
- Outbound calls cover telemarketing, follow-ups, upselling and collections.
Contact centers that add email and chat still only handle customer-facing work, so they rarely run payroll or enter data.
Service Delivery Models
BPO delivery
A BPO provider bundles several services under one contract. Customer experience, finance and logistics can sit under one roof with one set of reports.
That makes BPO multi-channel and easy to expand as new needs come up.
Call center delivery
A call center delivers one service, mostly through a single channel: voice. A call center vendor might handle customer service, sales and technical support, but all of it stays phone-based.
If you later need payroll or data entry, you’ll have to add a separate vendor or move to a BPO.
Cost Considerations
Call center costs
Call centers usually track cost per call alongside CSAT. Running one in-house brings upfront costs for infrastructure, telecom systems, recruitment and training.
Outsourcing shifts most of that to the provider and gives you predictable monthly costs.
BPO costs
BPO tracks spending across every outsourced function, so you can compare the total cost of a function with what it would cost to run yourself.
BPO may cost more at the start, but the savings grow over time, especially with nearshore or offshore teams.
Compare fairly
Make sure you compare like with like: an outsourced call center against a BPO, not against an in-house setup.
Which Should Your Business Choose: BPO or Call Center?
Choosing between a BPO or call center depends on how much of your business you want to hand off.
Pick a call center if:
- You only need phone support and one metric, such as CSAT, defines success.
- You face seasonal fluctuations, when you need extra agents without adding headcount.
- You want the smaller commitment.
Choose BPO if:
- Several functions need an owner, such as support, data entry and payroll.
- You’d rather manage one partner than several vendors.
If you’re unsure, start with a small pilot team and expand once it delivers results.
Are Call Center and BPO the Same?
No, but they overlap. An outsourced call center is one type of BPO, a subset of the broader outsourcing category.
Giva describes a call center as a specialized type of BPO, so BPO is the wider category that contains it. Many providers offer BPO contact center services alongside back-office work, and that causes most of the confusion.
However, many BPO tasks, such as payroll, accounting and inventory management, never involve a phone call. An in-house call center isn’t BPO at all, because no third party is involved.
Final Takeaway
The BPO and call center difference comes down to scope. Call centers handle voice-based communication and customer conversations. BPO covers both voice and non-voice processes across departments.
Neither model is better by default. The right choice depends on your business goals, budget and customer needs.
Many companies end up with a hybrid model, using BPO for back-office operations and a call center for customer-facing support. Choose the model that fills the gap you have today, and leave room to expand as you grow.
FAQs
Is a call center the same thing as BPO?
No. A call center handles customer conversations and can be in-house or outsourced. BPO always uses a third-party provider and covers a much wider range of front-office and back-office functions.
How do BPO and call centers track success differently?
Call centers track metrics such as CSAT, average handle time (AHT), first call resolution and sales per day. BPO measures how the whole business runs: whether processes are faster, costs are lower and revenue is higher.
How do I know which one my business needs: a call center or BPO?
Start with your biggest gaps. If phone support is the main need, a call center fits. If several functions such as support, data entry and payroll need help, BPO is the better choice.
Does BPO cost more than a call center?
Usually at the start, yes. BPO needs more setup and integration, but it can lower costs across the business over time. Call centers tend to have more predictable monthly costs.
Can a call center turn into a BPO?
Yes. Many call centers grow by adding services such as order processing, data entry and technical support, and gradually become full BPO providers.
Which gives better customer service?
Both can deliver excellent service. Call centers improve it directly through trained agents who talk to customers. BPO improves it indirectly by making the operations behind those conversations run better.
Can I use both BPO and call center services?
Yes. A common setup is BPO for accounting, HR and data processing, plus a call center for customer support, upselling and retention.
