Although we still believe that proper activity-based costing is the gold standard:
You can create individual surcharges in the admin area.
As with external costs, various variables and functions are available to you for this.
Whether material costs, in-house services or external costs — all values can be used to calculate surcharges automatically.
As with individual production tasks and external procurement, the formula editor is available here. You can choose from many system variables and use functions such as if, rangeswitch, roundup, etc.
Optionally, surcharges can be locked so that they cannot be changed in the calculation.
If you duplicate a production path, the surcharges defined for that path are copied.
If you duplicate the entire product, all surcharges are retrieved afresh and applied as defined in the admin area.
Here are a few examples:
Here, a surcharge of €50 is applied when manufacturing costs are below €200.
In this example, a 25% surcharge is applied to all in-house services.
Here, we calculate a flat surcharge of €25 plus another 5% of the total material costs.
