Hi Frode, >From what you are saying, the first part of the transaction is easy. It is a straight sales order process. However, the second is slightly tricky. Do you have the project module with you? You could run the second part as a project with visibility of all processes involved. In this way, firstly you are selling a product, (steel sheets or whatever). Next you are providing a service (adding value to another item, as the original steel sheet is now modified), and charging material used (if any), labour and other handling costs. This way your second invoice is only for value addition, and not for the base material supplied by your customer. I have run projects for a similar scenario where the client was conducting repairs on hydraulic equipment. Seemed to fit in very well. We were able to charge items from inventory, labour, machining costs, where necessary, all via projects. Cheers. Rajesh
