Key Points

  • Outsourcing your software development project involves hiring a third-party agency to handle all the tasks needed to build your software.

  • Businesses outsource software development because it is cost-effective and provides an efficient way of developing software without hiring an in-house team. Also, there is no need to manage your project yourself when you outsource to the right agency.

What Is Software Development Outsourcing?

Software development outsourcing is an arrangement in which a business hires a third-party (an external software outsourcing agency) to carry out all the tasks of building software that could be done in-house. 

These tasks can range from developing a content management system (CMS), custom web and mobile applications, and APIs to maintaining software. 

Outsourcing software is becoming increasingly popular, with businesses choosing to outsource due to benefits including quick access to a large talent pool of IT professionals and cost-effectiveness. 

Software project outsourcing is highly beneficial for startups and scale-ups that want to build an MVP quickly and launch without going through the hassle of hiring and vetting in-house developers. 

Businesses can use three software outsourcing models when choosing a development partner. They are onshore, offshore and nearshore development. 

In onshore development, an organisation will outsource a project to an agency or a dev team in the same country. For example, a business in the United Kingdom will outsource to developers located in the UK. 

Offshore development is when a business hires a team or an agency in a faraway country to build software. An example is a business in the UK outsourcing to a team in India. 

In nearshore development, a company will outsource to a team or an agency in a nearby country. What separates nearshore from offshore development is the difference in time zone. Nearshore developers are located in the same or similar time zone as your business, while offshore developers are in different time zones. 

Knowing the various outsourcing models will make it easy to choose the best partner from the top 15 development outsourcing companies in our list.
