Focus on your needs in the contract. The other party should be capable of focusing on their own needs. Worry about your profitability. Not the other parties profitability. You won’t sign a contract unless you both get what you need. The winner is not the one who obtains the most hostile provisions. It is the one looking a few steps ahead of the other. If your agreements don’t reflect your long term strategy and short-term tactics you are walking into a win/lose situation with one or both arms tied behind your back. Don’t do that. Your contracts are not only legal documents. They are the terrain on which you work to assure that you will maximize your fair share of the value generated by the relationship both during and after the contract. They don’t have to be long, detailed or hostile to accomplish that goal - in fact those attributes can interfere with that goal.
