Gluon Mobile: Change project from Free tier to Indie tier

I'm confused about the licensing options. Can anyone explain to me whether I can start developing my project with the Free tier and later change to an Indie tier? The reason I'm asking is because the possibility of changing tier wouldn't make sense from a business point of view, since that would mean that developers could simply develop their app under the Free tier until the end of the project and switch to the Indie tier right before compilation and distribution and cancel the Indie subscription after a month. 
So this must mean that I have to start developing with the Indie tier from the very beginning of the project if I don't want a nag screen, right?

A:

from the documentation

the free tier is available and fully functional for you to test with before parting with any money.
