I had to make the business make sense financially. I just needed to make my 15% look like his 50%. To do so, I reduced the nut to split by first deducting the cost of packaging, of technical support, the salaries for some developers on my side of the business to implement fixes, and when I still couldn’t get the math to pencil out, I added a $6 per unit Out of curiosity, is there an example contract text that demonstrates how to do this? Is it as simple as saying "You get 50% of the gross, but I'll deduct this, this and that from your share"?
