All cases are good. It just depends on how much you pay.

[Note: I am not an employee of the Qt Company, I don't know their sales 
strategy today. This was more or less the thinking 10 years ago during the 
Trolltech and Nokia days]

Suppose you developed the application internally using the open source version 
and invested 20 man-years of effort. Now it's time to ship and you contact the 
sales team. They may ask that you retroactively buy a commercial licence in a 
value between 0 and 20 years' worth. 

The exact value will be decided on a case-by-case basis. It's in the Qt 
Company's interest to get some money rather than none at all, so if 20 years 
of licence fees is unacceptable, they may lower it. Similarly, they may look 
into future revenue: how strategic is it for them to keep you as a client? 
Depending on who you are and what your application is, you could get 0 and a 
future discount!
