Which IT outsourcing companies should you put on your shortlist? It depends on the work you want to outsource and whether you need additional support, such as lead generation services, to build your sales pipeline.
\n\n\n\nHere’s a quick match:
\n\n\n\nThe right IT outsourcing provider is the one that fits your project, your security needs, and your budget. So, the biggest name isn’t always the best fit.
\n\n\n\nThis guide is for the people who make the final call: CIOs, CTOs, CFOs, and COOs. You’ll get a shortlist, a clear way to vet providers, and a simple way to work out the return on your investment.
\n\n\n\nDisclosure: Mercury Labs publishes this guide. We help B2B companies find new customers. We are not an IT outsourcing provider, we are not on this list, and no company paid to be included.
\n\n\nBelow are eight IT outsourcing companies, grouped by the type of buyer they serve best. Start with the “Best For” column. A provider that’s great for a Fortune 500 company can be the wrong choice for a 300-person firm.
\n\n\n\nCompany | HQ | Best For | Core Strength | Global Reach |
Accenture | Dublin, Ireland | Large enterprises changing how they run IT | Strategy, technology, and managed services at huge scale | Clients in more than 120 countries |
Cognizant | Teaneck, NJ, USA | Regulated industries like health care and finance | Updating old systems and running IT with help from AI | Large delivery teams, mainly in India |
DXC Technology | Ashburn, VA, USA | Enterprises that depend on older, critical systems | Running and updating complex systems without disruption | Enterprise clients worldwide |
Kyndryl | New York, NY, USA | Large companies outsourcing IT infrastructure | Managing data centers, networks, and cloud | Clients worldwide; spun off from IBM in 2021 |
EPAM Systems | Newtown, PA, USA | Companies building complex software platforms | Strong engineering, with AI built into its work | Operations in 55+ countries |
BairesDev | San Francisco, CA, USA | US companies that want teams in similar time zones | Adding engineers or full teams from Latin America | 4,000+ engineers, mostly in Latin America |
ScienceSoft | McKinney, TX, USA | Mid-sized firms that want one partner for many IT needs | Services from IT support to custom software | 35+ years serving clients in many countries |

\n\n\n\nAccenture is the usual pick when the work covers the whole company. It can handle strategy, cloud moves, and day-to-day IT under one contract.
\n\n\n\nExpect high prices and a lot of process. In return, you get scale few others can match.
\n\n\n\nCognizant has a strong US presence and large teams overseas.
\n\n\n\nIt’s a common choice in regulated industries, where knowing the rules matters as much as technical skill.
\n\n\n\nDXC works on systems many providers avoid, like mainframes and core banking software.
\n\n\n\nIt suits buyers who need to keep old systems stable while they slowly update them.
\n\n\n\nKyndryl was spun off from IBM’s infrastructure business in 2021. It runs the backbone of IT: data centers, networks, cloud, and backup systems.
\n\n\n\nChoose it when your main need is running infrastructure, not building software.
\n\n\n\nEPAM started as a software engineering company, and that is still its strength.
\n\n\n\nIt’s best when you need to build new digital platforms, not just maintain old ones.
\n\n\n\nBairesDev was founded in 2009 and is based in San Francisco. Its engineers work mostly from Latin America.
\n\n\n\nFor US companies, the main benefit is shared working hours at lower rates than US-based teams.
\n\n\n\nScienceSoft has been in business since 1989 and is based in McKinney, Texas. It offers IT support, cybersecurity, and custom software.
\n\n\n\nMid-sized buyers like having one partner cover many needs. Ask any provider on your list how much senior attention an account your size will get.

\n\n\n\nCompanies are outsourcing more, not less. Deloitte surveyed more than 500 executives for its 2024 Global Outsourcing Survey and found:
\n\n\n\nThe main question has changed. Buyers used to ask, “Who is cheapest per hour?” Now they ask, “Who can deliver results, with automation built in?”
\n\n\n\nHow buyers find providers has changed too. HubSpot’s 2026 State of Marketing report finds that buyers now start their research in AI search summaries. They visit vendor websites later.
\n\n\n\nThat means your shortlist may form before you talk to a single salesperson. A clear evaluation process matters more than ever.

\n \n Industry Insight: Most outsourcing deals don't fail because the provider lacks skill. They fail because the scope was unclear and no one managed the relationship.\n
Often, the provider did exactly what the contract said. The contract just described the wrong work. Before you compare vendors, write down three things: the results you want, who on your team owns the relationship, and how you’ll measure success every quarter.
\n\n\n\nEach provider had to meet five criteria:
\n\n\n\nThe list is grouped by use case. It is not a ranking.

\n\n\n\nOne person rarely makes this decision alone. HubSpot data shows the average sale involves five decision makers.
\n\n\n\nAn IT outsourcing deal usually involves IT, finance, security, legal, and purchasing. Get them aligned early, then follow these steps:
\n\n\n\n\n \n \n \n Expert Tip: Ask each finalist to describe a project that went wrong and what they changed afterward.\n
Strong providers give specific, honest answers. Vague answers now often mean vague answers later, when something breaks.
\n\n\nFew companies outsource everything anymore. Deloitte found that 78% of organizations also run their own in-house centers alongside outside partners.
\n\n\n\nA mix that works well:
\n\n\n\n\n \n \n \n Expert Tip: Keep at least one senior tech leader on your team who knows the systems you're outsourcing. You can outsource the work. You shouldn't outsource the judgment.\n
Find the right IT outsourcing company for your business by assessing its technical capabilities, industry experience, security practices, and ability to support growth.
