This paper is generally focusing on the customer and supplier relation in a product creation perspective. The work has specifically been performed together with a metal working SME, and a main customer to this company. Four criterias for a long term succesful relationship and business success was stated from the beginning of the project: In house efficiency; Openness in the chain of suppliers; Co-operative product development and Precision of quotation. Those four areas are all covered in case studies, in close relations to the SME. The problems to combine close relationships and competitive business between customer´s and suppliers are discussed in the paper. A specific task in the project has been to create a demonstrator, a prototype quotation generator for the SME. The goal for the demonstrator was to increase precision and decrease lead times in the quotation process. An evaluation prooves that this is possible, and the demonstrator will stepwise be implemented in the SME. During the project, the SME has had a significant growth. Investments in automation and 3D CAD are made. The project is funded by Vinnova and the companies involved.
