Short answer: a software development outsourcing company builds or extends software for you with its own engineers. To choose one, decide first which model you need (staff augmentation, a dedicated team or a fixed-scope project), then compare vendors on five things that protect delivery: who you interview, overlap with your working hours, how continuity is handled, how quality and AI tools are governed, and who owns the code. Price matters, but it only makes sense once those five are comparable.

GIGA IT is a software development outsourcing company with AI-augmented engineering teams in Latin America and a U.S. contracting entity. If you already know you need people inside your team, see our IT staff augmentation services. If you want a partner that owns a product stream end to end, start with nearshore software development with dedicated teams.

What a software development outsourcing company actually does

"Outsource software development" covers very different services. Before you compare companies, name the one you are buying:

ServiceWhat you getWhen it fits
Staff augmentationIndividual engineers who join your team and follow your managersYou have technical leadership and a roadmap, but not enough people
Dedicated development teamA squad with a tech lead that works only on your productA product area or new stream needs stable, long-term capacity
Project-based outsourcingA vendor-owned scope with milestones and acceptance criteriaThe scope is clear and unlikely to change much
Custom software development outsourcingDiscovery, architecture, build and support of a new systemYou need a product built and have no team for it yet

Most mid-sized companies end up combining models: a dedicated team for the core product and staff augmentation for peaks or scarce skills such as data engineering or MLOps.

Types of software outsourcing companies

Nearshore partnerOffshore vendorFreelance marketplaceLocal agency
Time-zone overlap with the U.S.Most or all of the workdayLimitedVaries by personFull
Who answers for deliveryThe partner, with governanceThe vendor, often through layersYouThe agency
Continuity if someone leavesPlanned replacementDepends on contractYour problemSmall bench
Typical useOngoing product work and team extensionLarge, stable, well-documented scopesShort, isolated tasksSmall projects near your office

Large, well-known providers such as Endava, Globant or BairesDev show how broad this market is. Whatever the size of the company you evaluate, ask the same questions: who exactly will work on your product, how close senior engineers stay to your leadership, and what happens when the team changes.

How to choose a software development outsourcing company: a scorecard

Use this scorecard in every vendor call. Score each line from 1 to 5 and ask for evidence, not promises.

CriterionWhat to askRed flag
Talent and selectionWill I interview and approve every engineer?Profiles you cannot meet before they start
Working-hours overlapHow many hours overlap with my team for stand-ups, reviews and incidents?A short daily window and async-only escalation
ContinuityWhat happens if an engineer leaves? How do you track engagement?"We will find someone" with no plan
Governance and qualityWhich code review, testing and security practices apply? Who reports on delivery?No defined quality gates or reporting
AI in deliveryWhich AI tools do engineers use, and how are they controlled?AI use that is either banned or ungoverned
Contract and IPWhich entity signs? Who owns the code and documentation?Unclear IP clauses or a contract outside your jurisdiction with no local entity
Track recordCan I see comparable cases and talk to a client?Only logos, no context

Where AI-augmented teams change the decision

AI coding assistants are now part of daily work for most engineers, but the 2025 DORA report found that AI tends to amplify what an organization already does well or badly. For an outsourcing decision this means the question is not whether a vendor "uses AI", but whether it has the practices that make AI safe and useful: small batches, strong code review, automated tests and clear ownership.

At GIGA IT, engineers work with AI copilots, automated testing and assisted code review inside your repositories and rules, and AI agents support QA, documentation and reporting. You keep control of what tools touch your code.

Cost: what drives it (and what to compare)

We do not publish rates, because the honest answer depends on the mix of roles, seniority, stack, overlap requirements and engagement length. When you compare proposals, check:

  • Whether the price includes technical oversight, replacement and reporting, or only hours.
  • Seniority actually assigned versus seniority quoted.
  • Notice terms to scale the team up or down.
  • Who pays for onboarding time and tooling.

A cheaper hourly rate with weak continuity often costs more over a year than a partner who keeps the same people on your product.

Frequently asked questions

What does a software development outsourcing company do?

It builds or extends software with its own engineers, either by adding people to your team (staff augmentation), providing a dedicated team, or delivering a defined project.

How do I choose a software outsourcing company?

Decide the engagement model first, then compare vendors on engineer selection, working-hours overlap, continuity, quality and AI governance, contract and IP, and comparable track record.

Is nearshore better than offshore for U.S. companies?

For ongoing product work, nearshore usually works better because teams share most of the U.S. workday. Offshore can fit large, stable and well-documented scopes.

Should I outsource a project or augment my team?

Outsource a project when the scope is clear and stable. Augment your team when you have technical leadership and a changing roadmap, and need capacity or a specific skill.

Who owns the code when I outsource software development?

It should be you. Check that the contract assigns intellectual property and documentation to your company and that the signing entity is in a jurisdiction you can work with.
