I hear this for the first time. I think that the companies, that are running an online casino should get a gambling license, not the software itself. It seems weird that you recommend never getting a gambling license. Do you want your buyers to run shady and illegal online casinos?
Even when someone buys your software, he will have to obtain a gambling license, in order to properly run a legitimate gambling business.
What do you mean by "unlike most platforms"? Are you saying that your software is somewhat special and unique, which removes the need of a gambling license? This sounds sketchy.
Anyway, good luck with sales, OP.
