Ask HN: Have you ever built and sold a software yourself?
To describe any of the aspects of the process, what is made to be sold once, what can be sold many times, what can be sold by subscription, which licenses are suitable, etc. Something that one or two programmers can build, we are not talking about large undertakings for which companies and teams are necessary.
It's nice to build, sell and earn something yourself, rather than working for someone else and selling your time. Lot more freedom and space for growth, and risk too.
