Corporate legal departements try to pull the same thing with B2B contracts, but in our experience almost anything can be changed if you stand your ground.
The legal department usually tries to tell us differently and gives the same kinds of arguments as they would give for the 'non-standard' employment contract. "You are only a small company and every other company accepts these conditions". "Only manager X of small department Y wants to do business with you: we won't change our conditions just for them". "The contract is only for few$, we can't do specials for that". But in the end the wishes of someone in the business are more important and conditions can be changed to satisfy both parties.
