    Hello, I’m a student currently working on a project. I’ve downloaded the open-source version of Qt because I don’t generate any income at the moment and can’t afford the $1,000/year license fee. In the future, I plan to publish and monetize my app. At that point, can I upgrade my Qt license from the open-source version to the small business plan and start paying $1,000/year before generating income from the app?

      @Kristupas

      As a student, you can apply for an Educational License here.
      You only need a valid email address of your institute.
      This unlocks some features and additional access to modules similar to a commercial license.

      AFAIK you are not allowed to switch between licenses for ongoing projects.
      I don't know the exact guideline on how to transition from OpenSource to Commercial, but if I'm not mistaken, you have to start over with a new project.

      You can also publish and sell your app using an open source license, if done correctly.

          Sorry can't tell what happens if you re-use the same code in a new commercial project...
          I can imagine that Ctrl + C, Ctrl + V copying the code base to a new project is also not allowed :D
          But as I've said before, I'm not a lawyer :)

            @Pl45m4 Is it possible to get in touch with Qt? Because as I imagine I will work on Open Source until I can pay the 1000$/year and then switch after finishing my project.

              • https://www.qt.io/contact-us#sales-contact

              The contact form ("Contact Sales") has a category extra for license related questions.
              Hopefully you will get your answer there.
