Outdated and Flawed Costing Logic

Why inaccurate cost structures lead to wrong decisions

We encounter this issue again and again in companies:

Cost calculations based on flat surcharges. Spreadsheets that once “worked well enough”.

And in the end, no one really knows why margins only exist on paper.

In reality, costing often becomes a black box:

  • It is unclear where costs actually arise
  • Work plans are outdated
  • Value flows and ERP logic are inconsistent

The result is generalized pricing that negatively impacts real performance.

This is not a criticism — it is the reality in many organizations, because the overall picture is missing.

The turning point

At some point, a clear reset is needed:

  • What does this product actually cost?
  • Where are the real cost drivers?
  • How much control do we really have over our pricing?
  • What would a truly reliable costing model look like?

What changes when done right

When costing is set up properly, everything changes:

  • Margins become transparent and realistic
  • Decisions become fact-based
  • Organizations gain clarity and control

Modern costing is not an add-on — it is a survival strategy.

If your prices seem stable but profitability does not follow, it is time to take a closer look.
