You can ask yourself three questions from the outset: Did the other party raise this request on their own initiative or through a third party? How much will it impact your company's resources (time, money, personnel)? Was the other party's expectation already set before you agreed? Establishing a clear supplier relationship evaluation process helps you make more rational decisions. Patisco's Seller Management module lets you record each supplier's collaboration history and notes, making it easier to evaluate the health of your working relationships.
