During the Ukraine crisis, a lot of food suppliers were faced with very high price increases for raw materials, energy, and transport. They wanted to increase their selling prices intermediate towards their customers, the food retailers.
In this case, an integrative negotiation was important to have, to have a better understanding of the impact for them (cost-price breakdown) and what important was for them at that moment e.g. besides a price increase they can give other variables to the retailer.
As a customer of that supplier, you don’t want to help them bankrupt because of the unforeseen price increases they were dealing with, with the consequence that you do have not any supply of the good and have out-of-stock in your own stores and customers were forced to change supermarkets for their daily groceries.
