How do you hire a software development company in the United Kingdom for your business? To find the right company, follow these steps:

  1. Make your RFP as specific as you can. Be sure to highlight your end goals and prioritize your feature list.
  2. Determine if your software development team’s location is important to you. With experienced and well-qualified teams located around the world, you’ll never run out of options. While nearshore and onshore software development companies are often easier to collaborate with due to their location, offshore software developers can be more affordable.
  3. Pay potential software developers to work with you on a small project. By bringing 2-3 of your top candidates on board temporarily, you’ll be able to assess the quality of their work and how well you collaborate with their team.

With hundreds of software development agencies to choose from, how do you get started? Our list of the best software development agencies includes client reviews, minimum project size, team size, specialty services, and client focus. Define the services you need, project goals, and budget to begin narrowing your choices.
