Thanks a lot for your answers but they didn't really solve my problem 😟
The thing is that the guy who does my accounting has to figure out what exactly I am being paid for.
Barbara Brundage got it pretty much right but what she wrote doesn't cover all aspects...
It's pretty hard to explain.
I used the term "author's fee" but it could also be that it's called "royalties"... I'm not native english speaking... 😟
It seems to be a huge difference here in Italy whether you make a profit from selling your own work directly (goods in this case), from receiving a percentage (someone else sells my stuff and gives me X percent) or from receiving money because I'm the author of the book that is being sold. They somehow classify each activity different here.
Not only as far as tax are concerned but above all because if you do a certain kind of work, you're only allowed to make a certain kind of profits... (at least that's how my accountant-guy explained it to me)
So I'm trying to find out what kind of profit I exactly get from selling my iBooks trough the iTunes Store.
Since I couldn't find too much on the net about that, I hoped to find help here... 😕
Hope I've been able to explain what I mean....
(By the way... what or who is OP?)
