If may seem unlikely that professional buyers would be interested in being able to "create joint value and divide it given concerns for fairness in the ongoing relationship." The fact is, though, they are, and for one very good reason. They know that in the vast majority of business-to-business deals, the long-term health of both buyer and seller comes not from negotiating over shrinking margins but, rather, from building long-term, profitable business relationships. So even though professional buyers can certainly be very tough negotiators, they understand that both you and they will be better off if you can come to an agreement in which both sides are satisfied.
