BPO, Nearshoring, EOR, Microsourcing, and so on… There’s plenty of industry jargon used in outsourcing today. According to HG Insights, the global spending in the outsourcing industry is estimated at just over US$138 billion annually. When any industry gets that big, there’s a good reason for the jargon.
Each bit of jargon becomes a descriptor for a product class or a set of services, as an endless cornucopia of outsourcing firms try to distinguish themselves in this fiercely competitive market. The differences in the jargon we use are no longer a trivial eccentricity, but a meaningful differentiator that can cost or save you money.
It is essential to understand the meanings of, and the differences between, these terms. This helps you determine the best way to maximize the benefits of outsourcing.

For starters, let’s talk about the term outsourcing itself. While the term “outsourcing” is often used interchangeably with the acronym “BPO”, there is a distinction between the two.
What is outsourcing?
Outsourcing is an umbrella term that describes any time a business or company contracts or uses third parties to perform tasks, supply goods, or provide services that would otherwise be handled internally as part of business operations.
When most people say “outsourcing”, it is also inferred that the third party providing the service is offshore, in some faraway place. However, most of us outsource without realizing it. The definition applies whether the third party is local, regional, or foreign.
What that means is that the company collecting and disposing of your garbage every week is, technically, “outsourcing”. Another example: you could cut or style your hair at home, but most people tend to “outsource” this to a professional hairdresser or barber.
These examples emphasize that outsourcing is a common and natural practice for most people. The complexity, as always, comes in the world of business. Businesses have specific needs, and outsourcing firms have matched those needs with a variety of product categories. This is where almost all the jargon comes from.
The geography of outsourcing
Now that we’ve established what outsourcing means, let’s define the geographic labels that get attached to it. These three terms describe where the outsourced work is being performed, relative to your business.
What is offshoring?
Offshoring is what most people think of when they think of outsourcing. Offshoring refers to outsourcing work to a company or team located in a distant country, typically on a different continent or in a vastly different time zone.
The primary driver of offshoring is cost reduction. Countries like Zimbabwe, Zambia, Costa Rica, the Philippines, and India have highly educated, English-speaking workforces capable of delivering work at comparable quality to US-based workers, but at a fraction of the cost. According to Deloitte’s Global Outsourcing Survey, cost reduction remains the number one reason why businesses outsource, cited by 70% of respondents.
What is nearshoring?
Nearshoring is similar to offshoring, except the outsourcing partner is located in a much closer country, typically one that shares a similar time zone, cultural affinity, or regional trade relationship.
For US-based businesses, nearshoring often refers to partnerships with companies in Latin America or the Caribbean. The appeal of nearshoring lies in its middle-ground position between the cost savings of offshoring and the logistical convenience of closer time zone alignment.
Some workloads also require partners who share a similar culture or legal framework to your country.
What is onshoring?
Onshoring (sometimes called domestic outsourcing) is when you outsource work to a third party still within your own country. This offers maximum cultural and regulatory alignment, but typically at a higher price point. Think of a New York-based company outsourcing its IT helpdesk to a firm in Texas.
Staff augmentation
Staff augmentation, also called on-site outsourcing, is a sub-category of onshoring that embeds outsourced resources “on-site” at the company’s premises. This is usually reserved for situations where immediate problem-solving and direct communication are required. Think of your accounting partner sending a bookkeeper to spend a week at your office to do the accounts.
We now know what outsourcing is, and we also know the geographic separations that occur within outsourcing. We can now expand on the different types of outsourcing.
What does BPO mean?
BPO (business process outsourcing) is where a business contracts or uses third parties to handle a specific business process within its operations. A business process is defined as an activity, or a set of activities, that achieves a specific organizational goal.
This definition sounds similar to the one above for outsourcing, and that goes some way in explaining why the word “outsourcing” and the acronym “BPO” are synonymous. The difference is subtle: where outsourcing defines an overall business strategy, BPO defines a product category within the outsourcing industry. We can clear things up with an example.
BPO case study
Say we have a doctor opening a new practice. The doctor will naturally want to focus on treating patients, but it takes more than a steady hand with a scalpel to run a successful practice.
We need marketing to draw the public (marketing & communications). The premises must be well-manicured and spotless to build trust with visiting patients (cleaning & sanitation). We’ll need someone keeping an eye on the books (bookkeeping & accounting), and the patients need a front desk person/receptionist to receive them (admin/first impressions). Not to mention the need for a lawyer/paralegal to advise the practice on how to remain HIPAA compliant.
The solution seems simple enough: hire people to do the work. So, the doctor hires five people, a digital marketer, a janitor, a receptionist, an accountant, and a lawyer. In theory, this is what the business needs, but in practice, it’s not feasible.
The doctor would be on the hook for:
- A marketer (~$65k/year)
- A janitor (~$29k/year)
- A receptionist (~$33k/year)
- A paralegal (~$60k/year)
- An accountant (~$50k/year)
We’re staring down a hefty salary outlay before a single patient is treated. This is where outsourcing can help, and, more specifically, business process outsourcing.
For a young practice, the doctor doesn’t really need a full-time and in-house marketer, paralegal, or accountant. These business processes can be outsourced.
- A digital marketing agency can handle a schedule of four posts a week. ($11k/year)
- A legal consultant can be contracted for five hours a week to advise on HIPAA compliance. ($15k/year)
- An accounting firm can do the books once a month to ensure the practice is in the black. ($17k/year)
That’s $132k/year in savings, all while filling all the key roles for this new business.
That is what BPO means: specific business processes placed in the hands of external specialists. It is primarily done to reduce the salary outlay, but it also allows your in-house staff to focus on their core competencies.
What are the different types of BPO?
With BPO demystified, we can look at the different product categories that fall under it.
What is information technology outsourcing (ITO)?
Information technology outsourcing, or ITO, is the contracting of IT functions and services to an external provider. This is one of the most established and widely used forms of BPO. Common ITO functions include software development, IT infrastructure management, cybersecurity, helpdesk support, cloud services, and data management.
For businesses without the resources to build and maintain a full in-house IT department, ITO provides access to specialist technical expertise at a predictable, manageable cost. It is especially common in industries like finance, healthcare, and e-commerce, where technology is mission-critical but not the core business.
What is knowledge process outsourcing (KPO)?
Knowledge process outsourcing, or KPO, takes BPO a step further by outsourcing high-value, knowledge-intensive work that requires deep expertise, analytical ability, and informed judgment. Where BPO typically handles process-driven tasks, KPO handles tasks that require specialized knowledge and decision-making.
Examples of KPO include legal research, market research and analysis, financial analysis and investment research, pharmaceutical research, data analytics, and business intelligence. KPO providers are typically highly educated professionals, often with advanced degrees, and the work they produce directly informs strategic business decisions.
What is professional outsourcing?
Professional outsourcing refers to the contracting of licensed or credentialed professionals to perform specific functions for a business. This overlaps somewhat with KPO, but the defining characteristic of professional outsourcing is that the work requires a recognized professional qualification.
Common examples include outsourcing legal work to a law firm, accounting and tax preparation to a CPA firm, HR advisory services to a human resources consultancy, or medical billing and coding to a specialized provider. Professional outsourcing is particularly common among small to mid-size businesses that need professional-grade output but cannot justify the cost of a full-time hire.
What is process-specific outsourcing?
Process-specific outsourcing is exactly what it sounds like: the outsourcing of one very specific, well-defined business process to an external specialist. Rather than outsourcing an entire function (like IT or accounting), process-specific outsourcing targets a single, clearly scoped workflow.
Examples include outsourcing payroll processing, customer onboarding, invoice processing, order fulfilment, or quality assurance testing. The narrow scope of the engagement makes it easy to measure performance and maintain quality control, which is why process-specific outsourcing is a popular entry point for businesses that are new to outsourcing.
What is project outsourcing?
Project outsourcing involves contracting an external team or provider to deliver a specific, time-bound project with a defined scope, timeline, and set of deliverables. Unlike ongoing outsourcing arrangements, project outsourcing has a clear start and end date.
Common examples include outsourcing the development of a new software product, the design and build of a new website, a market entry research report, or a one-time data migration. Project outsourcing gives businesses access to specialized talent for the duration of a project, without the overhead of a permanent hire or long-term contract.
What is manufacturing outsourcing?
Manufacturing outsourcing is the contracting of production, assembly, or fabrication processes to an external manufacturer, typically in a lower-cost country. This is one of the oldest and most widespread forms of outsourcing, and underpins much of global trade.
Businesses outsource manufacturing to reduce production costs, access specialized production capabilities, increase production flexibility, and focus internal resources on design, marketing, and distribution. Well-known examples include consumer electronics brands manufacturing in Asia, or apparel brands using contract manufacturers in South and Southeast Asia.
What is multisource outsourcing?
Multisource outsourcing, sometimes called multi-vendor outsourcing, is the practice of distributing outsourced functions across multiple external providers rather than relying on a single outsourcing partner. This is a strategic approach most often used by larger organizations managing complex, enterprise-scale outsourcing arrangements.
The primary advantage of multisourcing is risk mitigation: if one vendor underperforms or exits the market, the business is not entirely dependent on them. It also allows businesses to select best-in-class providers for each specific function, rather than accepting a compromise from a single generalist provider. The trade-off is increased management complexity, as coordinating multiple vendor relationships requires dedicated oversight.
What is microsourcing?
Microsourcing is a more recent term in the outsourcing lexicon. It refers to outsourcing small, specific tasks or “micro” projects to individual freelancers or small teams. Typically, this is done on a short-term or one-off basis. Think platforms like Fiverr or Upwork: you post a task, someone completes it, and the relationship ends there.
Microsourcing is useful for one-time needs: a logo design, a single blog post, or a quick data-entry task. However, it is not a long-term business strategy. Because the relationship is transient, there is no continuity, no institutional knowledge-building, and no real integration into your team culture or processes. The person completing your task today has no investment in your business tomorrow.
For businesses looking to build operational capacity and a genuine competitive advantage, staff leasing offers far more value than microsourcing. The difference between a microsourced task and a leased team member is the difference between hiring a taxi and hiring a personal driver; one gets you where you’re going once, and the other becomes an invaluable part of how you operate every day.
What is staff/employee leasing?
Staff leasing is one of the most powerful and most misunderstood models within the outsourcing industry. It is arguably the most relevant model for growing businesses in North America.
Here’s how it works: instead of outsourcing a business process to a faceless team you never meet or manage, staff leasing assigns you a dedicated, named individual, a remote team member who works exclusively for your business, on your schedule, following your processes, and integrated directly into your team. You get all the benefits of a full-time employee, without the overhead costs that come with one.
Those overhead costs add up fast. When you hire a full-time employee in the USA, the true cost of that hire goes well beyond the salary you agree on. Payroll taxes, Medicare, Social Security contributions, workers’ compensation insurance, health benefits, office space, equipment, and recruitment fees can add anywhere from 25% to 40% on top of base salary, according to the U.S. Small Business Administration. For a $50,000-per-year employee, you could easily be spending $65,000–$70,000 in total.
With staff leasing through a reputable offshore BPO provider, businesses can reduce their staffing costs by up to 65%, without sacrificing the quality, dedication, or professionalism of the team member.
At ZimWorX, this is exactly the model we operate. Our staff leasing solution gives you a pre-vetted, university-educated, English-proficient remote team member who is exclusively dedicated to your business. No shared resources. No rotating agents. Just one committed professional, working as a true extension of your team, from our world-class campuses in Zimbabwe, Zambia, and Costa Rica.
What is EOR & how does it differ from staff leasing?
EOR stands for employer of record. It is a legal and HR arrangement where a third-party company formally employs a worker on behalf of the client business. In an EOR arrangement, the EOR provider becomes the legal employer, responsible for payroll, tax compliance, benefits administration, and local labour law adherence, while the client business retains full day-to-day control over the worker’s tasks and output.
EOR is particularly valuable for businesses that want to hire talent in a foreign country but do not have a legal entity established in that country. Rather than going through the time-consuming and costly process of incorporating a local subsidiary, the business can use an EOR to compliantly hire in-country talent from day one.
So how does EOR differ from staff leasing? The distinction lies in the legal and structural relationship with the worker.
In a staff leasing arrangement, the BPO provider employs the worker and leases their services to the client. The worker operates from the BPO provider’s facilities, using the provider’s infrastructure and HR systems. The client business directs the work but is not the employer of record.
In an EOR arrangement, the EOR company employs the worker locally in the worker’s home country, handling all legal and compliance obligations, while the client retains control of the work itself. The worker may work remotely from home or a co-working space rather than from a BPO campus.
The practical difference comes down to what you need. If you want a fully supported, managed remote team member with access to office infrastructure, IT support, and on-the-ground HR oversight, staff leasing through a BPO provider is the better fit. If you need to compliantly employ an individual in a specific country where you have no legal presence, and that individual will work independently rather than from a managed facility, EOR is the appropriate solution.
Many growing businesses use both models in parallel, depending on the role and the country involved.
Which model is right for your business?
| Term | What it means | Best for |
| Outsourcing | Using any third party for tasks or services | General business strategy |
| BPO | Outsourcing a specific business process | Defined, repeatable tasks |
| Offshoring | Using talent in a distant, lower-cost country | Maximum cost savings |
| Nearshoring | Using talent in a nearby country | Time zone alignment + cost savings |
| Onshoring | Using talent within your own country | Regulatory alignment, domestic compliance |
| Staff augmentation | Outsourced resources embedded on-site | Hands-on, immediate problem-solving |
| Staff leasing | A dedicated remote employee, exclusively yours | Building long-term team capacity |
| Microsourcing | One-off tasks via freelancers | Short-term, isolated projects |
| EOR | A third party legally employs your remote worker | Compliant hiring without a local entity |
The model that delivers the greatest long-term value for small to mid-size businesses in the USA and Canada, particularly those looking to scale without the burden of spiralling overhead costs, is staff leasing with a trusted offshore BPO partner.
