Offshore software development is the practice of contracting software engineering, testing and maintenance to a provider whose delivery teams work in a distant, lower-cost country, typically in a different time zone from the client. India is the largest offshore delivery location, and most of the biggest providers are either headquartered there or run their largest engineering centres there. Clients use offshore providers for application development and maintenance, legacy modernisation, quality assurance, cloud and data engineering, and increasingly for building AI-enabled systems.
This list covers ten companies whose business is built on offshore engineering delivery, ordered by the most recent annual revenue each has published. It ranges from Tata Consultancy Services, which reported revenue of more than US$30bn in the year to March 2026, to the smaller engineering specialists Hexaware and Grid Dynamics.
Revenue indicates scale and staying power, not suitability for a particular project. Smaller providers are often a better fit for start-ups and mid-sized products, and providers with nearshore centres are covered in a separate list.

How offshore delivery works
In the standard offshore model, a small team located near the client (on-site or onshore) handles requirements, architecture and client management, while most engineering is done at offshore delivery centres. Work is usually organised either as dedicated teams billed per person per month, as fixed-price projects, or as managed services measured against service levels. Large providers operate at very high headcount: Infosys reported 328,594 employees at 31 March 2026, of whom 310,887 worked in service delivery, and TCS describes a workforce spread across 56 countries and 194 service delivery centres.
Dependence on export markets is high. Infosys generated 97.1% of its fiscal 2026 revenue from outside India, and Wipro derived about 62% of its IT Services segment revenue from the Americas and 27% from Europe.
Offshore, nearshore and hybrid models
The distinction between offshore and nearshore providers has blurred. Several companies on this list now combine Indian delivery with centres closer to their clients. EPAM, historically centred on Central and Eastern Europe, reported that India had become its largest delivery location, with about 12,200 delivery professionals there at the end of 2025. Grid Dynamics, headquartered in California, said India had become one of its top two countries by headcount, while it also runs nearshore delivery in Mexico and Jamaica. Coforge acquired Encora, which it describes as adding product engineering expertise and nearshore capability.
Methodology
Candidates were companies whose primary business is software development and IT services delivered substantially from offshore centres, mainly in India. Entries are ordered strictly by the latest annual revenue each company has disclosed: fiscal 2026 (year to 31 March 2026) for TCS, Infosys, Wipro and Coforge; calendar 2025 for Cognizant, EPAM and Grid Dynamics; the twelve months to September 2026 for HCLTech, as published on its website; and the current annual revenue figures that Tech Mahindra and Hexaware publish on their own sites without stating a period. Wipro's figure is in Indian rupees as filed with the US Securities and Exchange Commission; an approximate exchange rate was used only for ordering.
LTM (formerly LTIMindtree) and Persistent Systems were considered but are not ranked because their current revenue could not be retrieved from their own sites for this review. Headcount, founding dates and locations come from annual reports and company websites. No client reviews or ratings were used.
The list

TC
Largest India-based IT services company, part of the Tata group
Best for: Large enterprises outsourcing whole application portfolios
Tata Consultancy Services is the IT services company of India's Tata group. The group reports that TCS generated consolidated revenue of more than US$30bn in the fiscal year ended 31 March 2026, with a workforce spread across 56 countries and 194 service delivery centres. TCS provides application development and maintenance, enterprise platform implementation, cloud and infrastructure services, and business-process services. Recent initiatives named by the group include a partnership with OpenAI and a US$1bn investment from TPG in its AI data-centre business, HyperVault. Its scale makes it a common supplier for very large outsourcing programmes, but its standard delivery processes are designed for long-term enterprise contracts rather than small projects.

2
US-headquartered IT services firm with most delivery in India
Best for: US healthcare, insurance and banking clients
Cognizant reported full-year 2025 revenue of US$21.1bn, up 7.0%, and a headcount of 351,600 at 31 December 2025. Although its results are issued from Teaneck, New Jersey, the bulk of its engineers work in Indian delivery centres. The company provides application development and maintenance, modernisation, digital engineering and business-process services, with particular depth in healthcare, life sciences, banking and insurance. Its 2025 growth included about 2.6 percentage points from the acquisition of the engineering firm Belcan. Cognizant's combination of US management and Indian delivery makes it a frequent alternative to TCS and Infosys in North American sourcing decisions.

Software engineering firm that grew from Eastern Europe and now delivers most from India
Best for: Complex product and platform engineering
EPAM Systems traces its predecessor to 1993 and has its corporate headquarters in Newtown, Pennsylvania. It reported 2025 revenue of US$5,457.1m, up from US$4,727.9m in 2024, and had about 56,600 delivery personnel at the end of 2025. Originally known for engineering centres in Belarus, Ukraine and Central Europe, EPAM discontinued its operations in Russia after the invasion of Ukraine, and India became its largest delivery location, with about 12,200 delivery professionals at the end of 2025.

Risks in offshore engagements
Frequently asked questions
Which is the largest offshore software development company?
Tata Consultancy Services is the largest, with consolidated revenue of more than US$30bn in the fiscal year to March 2026 and a workforce spread across 56 countries and 194 delivery centres. Cognizant and Infosys follow, each with annual revenue of roughly US$20–21bn in their latest fiscal years.
Why is India the main offshore development location?
India combines a very large pool of engineering graduates, English-language business communication, decades of experience in IT outsourcing and lower labour costs than North America or Western Europe. The largest providers built their delivery centres there from the 1980s and 1990s onward, and Infosys, for example, now earns 97% of its revenue from clients outside India.
What is the difference between offshore and nearshore development?
Offshore development uses teams in distant countries, often with large time-zone differences, such as India for US or European clients. Nearshore development uses teams in nearby countries with overlapping working hours, such as Latin America for the United States or Central and Eastern Europe for Western Europe. Many providers now offer both.
How much does offshore software development cost?
Large offshore providers rarely publish rate cards; pricing is quote-based and depends on role, seniority, location, contract length and volume. Rates for teams in India are generally lower than for nearshore or onshore teams, but total cost also depends on productivity, management overhead and the share of work done on-site.
Are large offshore providers suitable for start-ups?
The largest providers are organised around multi-year enterprise contracts, and start-ups may receive limited senior attention. Mid-sized firms such as Coforge, Hexaware or specialist engineering companies like Grid Dynamics, or smaller boutique vendors, are often a closer fit for product companies that need a small, stable team.
