A company is experimenting with a new licensing model. It is called "Pay by use".
However, this does not make sense to me. In my understanding, "Pay by use" means: "I compensate for the hotdog by eating it". It has nothing to do with money.
IMHO, this should be "pay per use" (compensate for the hotdog per bite instead of the hotdog as a whole). It might also be possible that they want to express a temporal condition. In that case "pay at use" might be suitable (compensate for the hotdog when you start eating it, instead of when it is handed over).
I'd like to review whether "pay by use" is a legitimate payment model a company can live from and that "pay per use" is likely the correct term. I've never heard "pay at use", so I'd like your opinions on that in a context of making commercial benefit.
