Successful outsourcing begins with finding a reputable partner. In fact, finding the right partner could arguably have a greater impact on your success than any other factor. It’s essential to find someone who understands your needs, thinks strategically, and has the expertise to bring your web application or mobile app to life.

That’s why we’ve created this list of 19 top software development firms—experienced service providers who understand today’s top technology solutions and can help you at key stages in your product life cycle.

This list is a good place to start when searching for a vendor, but it doesn’t end here. Whoever you choose to work with, do your due diligence, vet them properly, and ask difficult questions before signing any contracts.

Top 19 Software Development Outsourcing Companies

We’ve identified the following software development outsourcing companies based on their reviews and ratings on Clutch.co and G2—two of the most comprehensive review sites for outsourcing firms on the internet.

Many on this list are full-service firms that offer not just front-end and backend development services, but also project management, user research, UX and UI design, QA testing, and maintenance.

Keep in mind that the data we’ve included is based on the public information listed on these and other sites. However, you’ll want to speak directly with each company’s sales reps to verify pricing ranges and services offered. After all, prices change and companies alter their offerings, and the data will only be as accurate as the source we referenced.

Nevertheless, this will provide a good starting point for companies exploring their options when looking into software development outsourcing services. And of course, we can guarantee all the data regarding Net Solutions is accurate—because that’s us!

Is Outsourcing Software Development a Good Idea?

Even though we’re a software development outsourcing firm ourselves, we recognize that there are advantages and disadvantages to outsourcing. While an outsourcing partner with years of experience can serve your business needs and help you achieve your goals, hiring an outsider comes with its share of risks—like any business decision.

Among the benefits of software development outsourcing, hiring an outsourcing partner to either support your in-house team or handle every aspect of your application development can:

  • Prove extremely cost effective
  • Increase efficiency and reduce your time-to-market
  • Bring new areas of expertise and different competencies to the table
  • Introduce you to new, cutting-edge technologies
  • Let you tap into a global talent pool

In terms of risks, working with an external team as opposed to relying 100% on in-house development efforts means you’re turning over some of your control to an outside entity.

This typically won’t be a problem if you work with high-quality, highly reputable IT outsourcing companies like those listed above. Just be sure to thoroughly vet anyone you work with and ask them about their cybersecurity protocols, data handling, and their areas of expertise.

Also, make sure that any potential partner is willing to understand and adapt to your internal processes, such as using your project management software and CRM.

Need a Partner for Your Next Software Project?

If you’re looking for a partner to support your business growth by either spearheading your software development projects or supporting your in-house software development team, we should talk.

Net Solutions is a leading software development firm that has worked with Fortune 500 companies as well as ambitious startups. We’ve got top-notch client reviews on G2 (4.9 stars) and Cluch.co (4.8 stars), and we can handle every element of software product development, from user research and design to development and QA.

Frequently Asked Questions (FAQs)

1.What is the difference between outsourcing and offshoring?

Outsourcing is a broad, all-encompassing term to describe hiring an outside company for software development services (or any other service, really). A large portion of the outsourcing market involves companies using outsourcing services like staff augmentation, hiring companies on the opposite side of the world to support their internal staff. That’s offshoring, which is a type of outsourcing.

Outsourcing also includes onshoring (working with companies within one’s own country) and nearshoring (working with development partners in nearby countries).

2.What is a software development outsourcing company?

A software development outsourcing company is an agency that works with a team of software engineers to support software product development and help deliver all your project requirements.

Full-service outsourcing firms can create software solutions from start to finish, using their own team of project managers, user research specialists, UI and UX designers, QA testers, and any other roles required to handle the entire development process.
