The 7 Largest Outsourcing Companies in the World, and What They Do

It wasn’t until the late ’80s that outsourcing was recognized as a legitimate method for increasing productivity in the workplace. But, by the ’90s, it became an integral part of doing business.

So, what’s outsourcing anyway? It’s the contracting out of corporate processes to third-party service providers, typically to save money on labor and tax expenses. By outsourcing business activities, businesses can increase efficiency and optimize their business processes, reducing operating costs and driving the company’s growth.

Many businesses also explore outsourcing to meet their back-office needs due to advantages such as better productivity and workload control — and the trend continues to strengthen since COVID.

Despite the fact that COVID-19 had a significant negative influence on the traditional outsourcing industry, the pandemic produced unexpectedly favorable outcomes as well. The outsourcing industry became busier during the pandemic.

Despite lockdowns occurring in cities throughout the world, business had to continue, and demand for outsourced specialists was higher than ever. For instance, when the Philippines entered a very long and rigorous lockdown in mid-March, BPO personnel were allowed to keep their employment and continue to work remotely.

Big names in the business process outsourcing (BPO) industry fill niches in sectors as varied as telecommunications, retail and e-commerce, utilities, financial services, business services, healthcare and pharmaceuticals, energy, and asset management.

What’s more, IT-enabled services, professional or legal outsourcing, research process, knowledge process outsourcing, and travel are some examples of subspecialties that have emerged as a result of outsourcing’s rapid expansion. In fact, from the years 2019 to 2024, the IT outsourcing industry is expected to grow from its current 44.6% market share at a CAGR of 9.4%.

For an industry growing exponentially, it’s only natural to see the largest players making billions in revenue.

In that spirit, we’ve put together a list of the top seven of them! Let’s dive in.

NTT Data

With $15 billion USD in revenue and more than 123,884 employees, Tokyo-based NTT Data has to be on any list covering the largest outsourcing companies in the world.

Nippon Telegraph and Telephone (NTT) is Japan’s dominant telecom provider and one of the world’s largest by revenue. When it comes to domestic fixed line, internet, and mobile phone connections, it formerly held a near monopoly but has since lost ground.

Nonetheless, it’s still by far Japan’s most important operator. Its mobile subsidiary NTT DoCoMo is its most innovative and lucrative business unit; its i-mode wireless internet service was a global first, even before the advent of 3G.

Quite like many Japanese firms, NTT is highly dependent on the home market. In order to maintain its position as the go-to provider of telecommunications services in the Far East, it has undertaken a number of small investments in other countries. But, still, corporate data and IT services constitute the bulk of its foreign business.

It spent $3 billion in 2016 to acquire Dell’s IT services business in the United States, which it folded into its NTT Data unit. In 2019, NTT replaced Verizon as the title sponsor of the IndyCar Series in the United States. NTT also has a partnership with Major League Baseball.

NTT Data is geared towards customer service management and business process outsourcing. It provides world-class support to customers at every stage of their journey and provides them with products and services that give them an edge in the market.

Based on extensive experience in the industry and strong partnerships, the company’s front-office BPO services offer an all-inclusive suite of CRM services options. By serving clients around the world, it managed to earn revenue equivalent to $109.2 billion USD, with a profit of around $7.8 billion USD in 2020.

Today, NTT DATA focuses on helping businesses in the areas of advice, planning, and execution. System integration, consulting, and IT outsourcing are just some of the many IT services and solutions offered by NTT DATA to the government, business, and finance sectors.

Its major services include:

  • Cloud services
  • Cybersecurity
  • Data and Intelligence
  • Application development management
  • Large-scale project delivery and process design

Headquartered in New York City, IBM is a multinational information technology corporation serving more than 170 countries. It provides information technology outsourcing and a variety of sophisticated business process outsourcing (BPO) services to businesses in a wide range of sectors.

In the 1980s, IBM lost its market supremacy in computer hardware when it permitted other businesses to clone its PCs. However, the company effectively rebranded itself as the world’s leading technology consulting and services firm, yet continuing to be a dominant force in the corporate server and storage device markets. Therefore, it was one of the few IT organizations to weather the dot-com downturn relatively undamaged. In fact, it emerged through the turn of the millennium in a better form than at any time in the previous two decades.

Later, IBM had to deal with fierce competition from other tech giants. The company responded by expanding into unrelated fields such as artificial intelligence, data security, blockchain, cloud computing, and digital marketing. IBM iX, one of the world’s largest digital development and marketing services companies, is part of the company’s broad worldwide services division.

In 2020, Ad Age predicted a worldwide marketing industry of $5.5 billion USD. The company widened its focus by acquiring several large-scale businesses. Some prominent names include weather forecaster, the Weather Company, and open-source software maker, Red Hat. When the latter deal closed in the summer of 2019, it represented IBM’s largest acquisition to date and had a price tag of $34 billion.

Today, IBM is a giant, leading outsourcing company. Some of its major clients include Datameer, Tech Mahindra, and Intel. Quite recently, the company has started focusing more on fields like IoT, big data analytics, and machine learning. Other outsourcing services include:

  • Financial and consulting services
  • Talent acquisition
  • Staff augmentation
  • Procurement strategy
  • Financial planning and analysis

Frequently Asked Questions

Which country leads in terms of outsourcing?

The outsourcing industry worldwide was worth $92.5 billion in 2019 and is expected to grow to $405.6 billion by 2027.

According to A. T. Kearney’s Global Services Location Index, India has been the top country for outsourcing, thanks to its large pool of highly skilled IT and software development professionals.

However, because of the proliferation of new information technology and telecommunications firms in the United States, North America took the lead worldwide in the outsourcing business.

Right now, the U.S. has the highest rate of outsourcing in the world, with about 68% of businesses using this strategy. It’s also growing in the UK. The lack of available talent is the primary reason so many companies in the United Kingdom (48%) are considering moving their operations elsewhere.

What makes outsourcing so popular?

A 2019 poll of U.S. small businesses revealed that nearly 40% were already outsourcing tasks, including IT services, accounting, and digital marketing to improve productivity, gain access to specialized expertise, and free up in-house resources.

In another survey conducted in 2020 by a B2B research firm, it was found that 80% of American SMBs wanted to use outsourcing services in 2021.

So, what exactly makes it so popular?

The rise of remote work and the quickening pace of digital transformation in firms are the primary drivers of this popularity. These factors have made outsourcing more practical and more appealing to businesses that want to save money, improve customer service, and develop new products and services.

What are the different types of BPO services?

BPO services can be broken down into two categories:

  • Front Office
  • Back Office

Tasks like billing, record keeping, and accounting fall under the category of “back office services,” which also includes similar tasks that do not involve direct contact with customers.

In contrast, front-office support includes administrative tasks that directly benefit the company’s customers, such as sales, support for the company’s information technology infrastructure, and customer service.

What's the difference between offshoring and onshoring outsourcing?

When a business decides to work with a business process outsourcing (BPO) firm located in a country with lower labor and tax rates, they are said to have “offshored” its operations. Consider the case of a U.S. firm contracting with a Philippine business process outsourcing (BPO) firm.

On the other hand, when a corporation contracts with a business process outsourcing (BPO) provider located in the same country but in a different region, this is known as “onshore outsourcing” or “onshoring.”

When can you think of outsourcing for your company?

Your organization may choose to outsource its IT tasks if it no longer wants to build or manage its own business process services, infrastructure, or service/help desk support.

In addition to the aforementioned, there are a plethora of other services that you can get through outsourcing. This includes (but is not limited to):

  • Network monitoring and troubleshooting
  • Security and virus protection
  • App development
  • Storage and data recovery
