I've been selling plugins for a couple years now but never have I sold more than $ 750 in a single day. Yesterday thanks to selling a double team license and a couple of developer licenses sales suddenly spiked to $ 1,067 in a single day.
I've been planning to finetune the Doka license model and I might have to move this forward. The difference between the developer and a team license isn't very big at the moment (it's basically priority support) so more differentiation might push companies to team licenses more often.
