Keyline calculated on the basis of the hourly rates for personnel and machines that you define (stored in Keyline as means of production).

Each means of production gets its own formula for each capability and the required time and material consumption or external costs (such as click costs).

In Summ Keyline can calculate the required price and you can individually define a margin (in %) on the calculated total sum for each order.

A classical contribution margin calculation does not take place.
