IT outsourcing is one of the largest global businesses and a booming industry in 2025. In fact, according to Deloitte’s 2024 survey, more than 76 percent of companies outsource key technical tasks, with coding, quality assurance, and UI/UX design being some of the most popular.
Whether you want to develop a new product or launch a custom software solution, top IT outsourcing companies can help you cut costs and speed up timelines without sacrificing quality.
What is an IT Outsourcing Company?
Definition and Scope of IT Outsourcing
An IT outsourcing company refers to any third-party service provider managing IT-related tasks for a company. They may oversee specific tasks and projects, partial functions (e.g., software testing), or the entire technical operations of an organization.
The scope of these services is variable and can range from custom software development to UI design. Individual contracts help clarify expectations by outlining deliverables, deadlines, and performance targets.
Types of IT Outsourcing Services
IT outsourcing services fall under three main models, with varying benefits and limitations.
Onshoring refers to companies located within the same country. These teams operate on a similar schedule, with similar work and communication styles. Because of local labor costs, these teams are typically the most expensive. Their biggest benefit is that they circumvent the hassle of managing an in-house team.
Nearshoring companies are often based in nearby LATAM countries like Colombia. With this type of arrangement, there are minimal time differences, usually one to three hours. Companies can hire specialized talent at lower rates without dealing with major communication barriers.
Offshoring deals with teams based in low-cost zones, like India or the Philippines. While these deals result in the most cost savings, they also come with language barriers and inconvenient time differences that can go up to 12 hours.
Benefits of Outsourcing IT Services
Cost Efficiency and Budget Control
Outsourcing can reduce overhead costs by up to 70 percent. Companies no longer need to invest resources in hiring, training, and maintaining an in-house team. With project-based agreements, you can predict exact design and development costs.
Access to Global Talent
Having an off-site team reduces hiring limitations by giving you access to a global talent pool. These experts often have niche specialties and are willing to collaborate at competitive rates.
Outsourcing companies can tap into their extensive network and onboard these international resources immediately, speeding up hiring.
Focus on Core Business Activities
By delegating software development and other technical support functions, businesses can free up their internal teams to work on strategic plans that drive growth.
That means in-house teams can spend more time on high-value activities like ideation and concept development.
24/7 Operations and Scalability
A huge benefit to having a nearshore software development team is the ease of scalability. Business owners no longer need to plan around internal operations management.
Nearshore teams can onboard project-based experts or other specialists from a readily available talent pool whenever needed.
How to Choose the Right IT Outsourcing Partner
Criteria to Consider Before Hiring
Before you choose an outsourcing partner, consider what services they offer. Review their portfolio to ensure they have experience in your industry and relevant technical skills.
Regions with Strong IT Outsourcing Presence
Location is another factor to consider. Latin American companies based in Mexico or Colombia are ideal partners for North American businesses because of their proximity and time zone alignment.
These countries have a strong tech industry with top talent trained on the latest development practices.
Evaluating Performance and Communication Standards
Ensure the outsourcing company has clear communication protocols and is responsive. Leanware’s agile project management style relies on routine check-ins, direct communication with clients, and frequent milestones to prevent misunderstandings or delays.
