We have been active in creating websites already for some years, but recently we started also with web-based software.
So we started to look for partners to sale our production around the world.

One partner company is interested in selling our products, but we can't agree in %, we would give them for sales.
We offer them about 20%, they want around 50%.

our responsibilities and expneces: all that is needed to create new software - software, hardware, expences on programmers, design, etc.

partner's responsibilities: selling our products, promoting and advertising us in their region.

so what do u think, folks, what should the proper % be?
