What Is Outsourcing in Business? Types, Examples & Costs

Should you build it in-house or pay someone else to do it? Every growing company hits that question sooner or later, and outsourcing is one of the most common answers.

This guide explains what outsourcing actually means, the main types, real examples, what it costs, the models you can use, and how to decide what to hand off and what to keep close.

What is outsourcing in business?

Outsourcing is the business practice of contracting a third party provider to perform tasks or business functions that a company would otherwise handle with its own in-house team.

Outsourcing involves contracting an external service provider to take over specific business processes and business operations, from a one-off particular task to an ongoing function, handled by anyone from a solo freelancer to a large outsourcing company.

The word is a contraction of "outside resourcing" and moved into common business use in the early 1980s, as firms began buying capabilities they once built internally (see the origin of the term).

A company hires an outside company when it decides that buying a capability is faster, cheaper, or better than building it itself, which lets it stay focused on its core competencies rather than spreading internal resources thin.

Outsourcing can be domestic or international. Hiring a local accounting firm or law firm down the road is outsourcing. So is contracting a software development team in other countries. The defining feature is not distance; it is that the work sits with an outside party rather than on your payroll.

In plain terms: outsourcing is paying an outside expert to do something so your own team does not have to.

How does outsourcing work?

From our experience handling global onboarding for 300+ companies, we have learned how outsourcing really works once the contract is signed. At a basic level, a client company agrees on scope with a service provider, signs an outsourcing agreement, transitions the work, and then manages the relationship over time.

The provider brings its own people, tools, and processes, and the client pays for an output or an ongoing service instead of for headcount.

Most engagements follow four steps:

1. Scope. Define exactly what work is moving out: a task, a project, or a whole process, and what "done" looks like.
2. Contract and SLA. Sign a contractual agreement or a statement of work (SOW). A service level agreement (SLA) sets quality standards, turnaround times, reporting, and confidentiality.
3. Transition. Hand over knowledge, access, and any assets the provider needs to start delivering.
4. Manage. Track performance against the SLA, review regularly, and adjust as needs change.

The most useful distinction to hold onto is "buy a task" versus "hand over a process." Paying a freelancer to design a logo is buying a task. Handing your entire customer support operation to a provider that owns staffing, tooling, and quality is handing over a process. The second needs far more governance than the first.

What are the main types of outsourcing?

There are two ways to categorize outsourcing, and a few different types fall under each: by location (where the provider sits relative to you) and by function (what kind of work is being done). Most real arrangements combine one of each, for example an offshore BPO contract or a nearshore IT team.

How does outsourcing differ by location?

Location, whether the provider sits in your own market or in other countries, decides your cost, your time-zone overlap, and how much day-to-day control you keep.

Onshore outsourcing keeps the work in your own country, nearshore outsourcing uses providers in nearby countries within a few hours of your time zone, and offshore outsourcing moves it abroad to cut cost. A fourth variant, onsite outsourcing, has the provider's contractors working physically at your own location.

The four sit on a spectrum. Onshore versus offshore is the widest gap on both cost and overlap, while nearshoring splits the difference by hiring providers in a nearby country in a similar time zone, and onsite keeps contractors in your building. There is no single "best" option; the right one depends on how much overlap and oversight the work needs.

What are the types of outsourcing by function or model?

Function is the second lens, and it maps to the kind of work being handed over rather than where it sits. Five models cover most arrangements:

• Business process outsourcing (BPO): handing over an entire process such as customer support, payroll, claims handling, or data entry.
• IT outsourcing (ITO): also called information technology outsourcing, covering software development, infrastructure, helpdesk, and managed IT services.
• Knowledge process outsourcing (KPO): higher-skill, judgment-heavy work such as research, data analysis, and financial modeling.
• Professional outsourcing: specialized services like legal, accounting, or design.
• Manufacturing outsourcing: contracting production of physical goods to a third-party factory.

In practice these blur together. A single contract might pair an offshore location with a BPO function, or a nearshore team doing ITO, so most real deals are a location choice and a function choice stacked on top of each other.

What functions and tasks do companies commonly outsource?

The most commonly outsourced functions are information technology and software, customer support, finance and accounting, human resources and payroll, marketing and content, manufacturing, and logistics.

In practice, companies tend to outsource business processes that are specialized, repeatable, or outside their core product, and the outsourcing services on offer span both front-office and back office operations. Providers can provide services on a project basis or as an ongoing function.

Common categories include:

• IT and software: development, QA, infrastructure, and helpdesk.
• Customer support: phone, chat, and email, often handled through a call-center or contact-center provider offering center support.
• Finance and accounting: bookkeeping, accounting, accounts payable, and tax prep.
• Human resources and payroll: HR outsourcing, recruiting, onboarding, and payroll processing.
• Marketing and content: marketing services, design, content production, and paid media.
• Manufacturing and logistics: production across the manufacturing industry and supply chain functions like warehousing and fulfillment.

A few concrete examples make it real. A seed-stage startup hands its bookkeeping to an accounting firm so the founders can stay on product. An ecommerce brand contracts a factory to manufacture its goods instead of building its own plant.

A growing SaaS company routes tier-one support tickets to a BPO provider so its in-house engineers keep shipping. In each case, the company keeps what defines it and buys the rest.

What are the advantages and disadvantages of outsourcing?

The benefits of outsourcing include cost savings on labor costs, access to specialized expertise, and the ability to let a team focus on its core product and build a competitive advantage.

Done well, it can improve efficiency and cost efficiency at once, and these potential benefits are why external vendors have become a standard part of modern business operations.

But it also means less direct control for the hiring company, communication difficulties made worse by cultural differences and distance, and exposure of sensitive data or intellectual property. Whether it pays off depends far more on what you outsource and how you manage the security risks than on outsourcing itself.

For context on scale: the global business process outsourcing industry was worth about $303 billion in 2024 and is projected to reach roughly $525 billion by 2030, according to Grand View Research. Appetite is strong at the small end too.

A Clutch survey of more than 500 US small business leaders found that 83% of small businesses planned to maintain or increase their spending on outsourced business services in 2023. Used well, outsourcing can lift productivity and lower operational costs at the same time, which is a large part of why it is now a mainstream way of working, not a fringe tactic.

One shift is worth calling out. Cost used to be the main reason companies outsourced; now it is one reason among several. In Deloitte's 2024 Global Outsourcing Survey, only 34% of executives named cost reduction as their primary driver, down from about 70% in 2020. Access to talent, speed, and specialized capability now carry as much weight as savings.

What are the criticisms and risks of outsourcing?

Outsourcing carries reputational and operational risks alongside its benefits. Internally, decisions to outsource can threaten the job security of existing staff and dent employee morale, especially when roles are moved abroad. Externally, public opinion often frames outsourcing as wage-cutting, and a poorly handled move can generate negative publicity.

Operationally, handing work to an outside party can mean a loss of control over quality and processes, and a weak provider can deliver lower-quality work than an in-house team would. None of these are reasons to avoid outsourcing outright, but they are reasons to communicate clearly with your team, vet providers carefully, and build quality controls into the contract from day one.

How is outsourcing different from offshoring and BPO?

Outsourcing, offshoring, and BPO are related but not the same. Outsourcing is about who does the work (an external party). Offshoring is about where the work happens (another country). BPO is about how the work is delivered (an entire process, run to agreed service levels).

A quick memory hook: outsourcing is who, offshoring is where, BPO is how. As the difference between offshoring and outsourcing shows, you can offshore without outsourcing (your own overseas team) and outsource without offshoring (a local agency).

The distinction that matters most in practice is managed versus unmanaged. In a managed model, the provider owns the outcome: staffing, tools, quality, and results. In an unmanaged model, you get people or capacity but still manage the work yourself, which is closer to staff augmentation than to outsourcing. Confusing the two is where a lot of outsourcing disappointment comes from.

How do you decide what to outsource and what to keep in-house?

Having onboarded more than 2,000 employees for global companies, we have learned where the line between outsource and keep in-house tends to fall. The simplest test in any outsourcing strategy is whether a function is a core differentiator.

Keep the work that defines your product, brand, and strategy with your in house team, and consider outsourcing work that is repeatable, specialized, or non-core. When you decide to outsource, a short checklist beats a gut call.

As management thinker Peter Drucker is widely credited with putting it, "Do what you do best and outsource the rest" (a line also attributed to Tom Peters).

The idea is simple: protect the front-of-house work that customers actually choose you for, and hand off the back-office work that someone else can run better or cheaper.

Run each function through these five questions:

1. Is it a competitive differentiator? If it is part of why customers choose you, keep it in-house.
2. Is it repeatable and rules-based? Predictable, well-defined work is easier and safer to outsource.
3. How sensitive is the data or IP? The higher the risk, the more oversight or in-house handling it needs.
4. What does it cost to build versus buy? Compare the true cost of hiring, tooling, and managing internally against a provider's price, factoring in the business expenses and production costs each option carries. The goal is to reduce costs without losing quality.
5. Do you need control or just capacity? Control points to in-house or a dedicated team; pure capacity points to a provider.

As a rule of thumb, keep strategy, product direction, and brand voice in-house, and hand off execution-heavy or highly specialized work to reduce peripheral business expenses. Outsourcing your core is how companies lose their edge; outsourcing the right supporting work is how they move faster.

How much does outsourcing cost?

Outsourcing is priced in a few standard ways, and the total depends on location, skill level, seniority, and volume. Rates range widely, from a few dollars an hour for basic offshore support to premium rates for specialized onshore expertise, so the pricing model matters as much as the headline number.

The trap is treating the quoted rate as the full cost. Real spending also includes transition time, management overhead, and the cost of switching if it does not work out.

Deloitte found that 70% of organizations brought previously outsourced work back in-house over the past five years, often to regain control or avoid vendor mark-ups. That move, sometimes called insourcing, is expensive, which is why the cheapest bid rarely wins.

A slightly higher rate from a provider that delivers reliably usually costs less over a full year than a cheap one you have to replace.

How do you choose the right outsourcing provider?

After processing $20M+ in payroll for our clients, we have seen what separates a reliable provider from a costly one. Match the provider to the job, check their track record, and confirm they can protect your data before you sign.

Outsourcing providers vary widely, and the best external vendor for a one-off task is rarely the best one for a critical ongoing process, so start by being clear about which you are buying. Poor provider choice shows up fast in slipping deadlines and falling customer satisfaction.

Work through this vetting checklist:

• Fit for the work: Task providers and full-process providers are different animals. Match the model to what you actually need.
• Track record and references: Ask for clients in your industry and at your stage, then actually call them.
• Security and compliance: Look for SOC 2, ISO 27001, and clear data-handling and confidentiality terms.
• Communication cadence: Confirm reporting frequency, communication methods, named contacts, and enough time-zone overlap to work together. Agree the KPIs you will review.
• Contract and exit terms: A master services agreement (MSA) plus an SLA should define quality standards, penalties, and a clean way out before you are locked in.

Watch for red flags: opaque reporting, no named team you can talk to, reluctance to sign an SLA, and a pitch that competes only on being the cheapest option. Any of these usually costs more later than it saves upfront.

Signing the contract is the start, not the finish. Successful outsourcing relationships rely on ongoing relationship management and effective communication, not just the paperwork: regular check-ins, clear escalation paths, and shared metrics do more to protect quality than any single clause.

A typical outsourcing process runs from identifying the tasks to move out, to selecting a provider, to defining the contract and SLA, and finally to managing the relationship over its full life.

What are the models for accessing outsourced talent and services?

Once you know what you want to outsource, there are four practical outsourcing models to get it done, and they fall into two paths: building the capability as your own, or running the outsourcing process through an external organization.

The right model depends on how much control, permanence, and management you want, and on how much of the work you are comfortable handing to an outsourced provider.

Path A: build the capability in-house

Path A keeps the people as your own. You carry more of the setup and compliance load, but you keep full control of the work, the IP, and the culture, and the two options differ mainly in how much of that load you shoulder yourself.

1. Set up your own legal entity: You incorporate in the target market and employ people directly. This gives you full control over employment, IP, and culture, but it carries the heaviest compliance burden and the longest setup time. It fits companies with a long-term commitment and real headcount to justify the overhead. A build-operate-transfer (BOT) arrangement is a phased way into this.
2. Use an Employer of Record (EOR): An EOR legally employs people on your behalf while you direct their work and own the output. The EOR handles payroll, benefits, and compliance, so you can hire in days rather than the months an entity takes. It fits growth-stage companies that want in-house control without the infrastructure. If you go this route, our guide on how to choose an EOR and the comparison of PEO versus EOR are useful next reads.

Both routes give you your own team rather than a vendor's process; the entity trades speed for total ownership, while an EOR trades a little of that ownership for the ability to hire in days.

Path B: outsource to an external provider

Path B hands the work to someone else, with the two options sitting at different points on the control-versus-convenience scale: staff augmentation gives you people to direct, while managed services gives you an outcome to receive.

1. Staff augmentation (the staffing model): A firm supplies people who work exclusively for you and integrate into your workflows, but remain employed by the staffing company. It gives you more control than a managed service and less commitment than a direct hire. See staff augmentation for how it compares.
2. Managed services or project outsourcing: The provider takes full delivery responsibility for the outsourced tasks. This includes agencies on retainer, white-label providers, BPO providers from the wider BPO industry, and project freelancers, and covers everything from back-office outsourcing to full recruitment process outsourcing (RPO). It fits when you want outcomes and reporting, not people to manage.

The choice comes down to whether you want to manage the people or just the results, so pick augmentation when you need hands in your workflow and managed services when you'd rather own the outcome than the day-to-day.

One useful frame from the research on modern sourcing is what the University of Tennessee team, led by Kate Vitasek, calls vested outsourcing: a shift away from adversarial, cost-cutting contracts toward outcome-based partnerships where both sides share in the results. It is the same move Deloitte's data shows, from cost as the only driver to value and capability.

How Wisemonk fits: one partner, every model

This is exactly what we do. Wisemonk delivers all four of these models under one roof, so you are not stitching together an entity provider, a staffing firm, and a managed vendor separately.

You can hire directly through our EOR, build a dedicated offshore team, augment your existing team, or run a fully managed function, with zero entity overhead, drawing on our experience managing 2,000+ employees for global companies.

What are the modern alternatives to traditional outsourcing?

Traditional hand-off outsourcing is no longer the only option. Companies that want more control now choose from a spectrum of models: freelancers, BPO, staff augmentation, dedicated offshore teams, Employer of Record, and fully owned offshore centers.

The trend is toward models that keep the work closer while still tapping global skilled labor and specialized skills through external providers, and it works as well for routine functions as it does for complex projects.

The spectrum runs roughly like this, from least to most control:

Freelancer > BPO > Staff augmentation / dedicated team > Employer of Record > Owned capability center

• Staff augmentation and dedicated teams give you people who work as an extension of your team, rather than a black-box process.
• Employer of Record lets you directly hire full-time employees in another country without setting up a local entity, so you keep control of the work while a partner handles compliance and payroll. When it does not fit, there are also EOR alternatives worth weighing.
• Global Capability Centers (GCCs) and offshore development centers are your own owned offshore teams, the far end of the control spectrum.
• Agentic AI is starting to reshape delivery across all of these, with 83% of executives in Deloitte's 2024 survey already using AI as part of their outsourced services.

The common thread is control and IP retention. When you want your own people and your own institutional knowledge, rather than renting a vendor's process, a dedicated team or direct-hire model tends to fit better than classic BPO, and it changes how you run the relationship, from vendor management to managing an offshore team as your own.

What do companies say about working with Wisemonk?

Frameworks are one thing; results are another. The real test of a dedicated-team model is whether it holds up for companies actually running it, and the pattern in Wisemonk's reviews is consistent.

Global teams point to the same three wins over and over: onboarding measured in days, full control of the work, and compliance they stopped losing sleep over. Wisemonk holds a 4.8 out of 5 rating on G2 across 240+ verified reviews, and the stories behind that number make the model concrete.

"Wisemonk played a key role in helping us hire for specialized B2B SaaS marketing skills. We built the team within four months and hired experienced professionals from Tier 1 B2B SaaS brands, across SEO, digital marketing, business development, and GTM roles. They're a great partner and I'd recommend them to any B2B SaaS vendor." — Saurabh Sharma, Co-founder & CEO, Onereach (USA)

"We've handled everything from payroll and statutory compliance to equipment procurement and benefits enrollment, all with a level of responsiveness and professionalism that makes managing a remote team from Canada feel seamless. We'd happily recommend Wisemonk to other companies looking to hire and manage talent." — Monika Russell, CFO, Minehub (Canada)

"Wisemonk onboarded all of my employees in one or two days and paid their salaries the day after my payment cleared. Over a year later, my employees and I remain very satisfied. I think of them as our HR department." — Frank Menes, Founder & CEO, Senem RFP (USA)

The through-line is control without the overhead: keeping full direction of the work while a single partner absorbs payroll, benefits, and compliance. That is why growth-stage companies increasingly reach for a dedicated team over a traditional black-box outsourcing contract, and it's the same shift Deloitte's data shows industry-wide, from cost as the only driver toward value, speed, and capability.
