Once the product has been configured in Keyline, a list of costs is displayed at the end.
Separated according to the task of the individual means of production, you can see the amount of work in minutes and euros. Material consumption and the costs incurred for it are shown separately, as is the position of external costs.
You can now decide how high you want to set the margin (e.g. fixed 30%), or whether the customer should receive the product at a fixed price (e.g. 300€). In this case Keyline will display the expected margin. 

Keyline does not perform classic contribution margin accounting.
