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

  1. Ask what procedures the software testing company follows and which project management tools the team uses to track bugs and manage tasks. When testing software, it’s essential that your QA company is organized and methodical in its approach.
  2. Look for a software QA company that can conduct different types of tests. Outline your goals and describe your software project in detail. Your potential partner may recommend certain tests over others, helping you reach your goals.
  3. Interview former clients about how well their software performs function. After working with the software testing company that you’re considering, did the clients find any other issues? Were they able to resolve them?

With hundreds of software QA companies to choose from, how do you get started? Our list of the best software QA companies 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. If you need help creating a shortlist, tell us about your project and receive personalized recommendations.
