Use a shipping block, not isolated values
Shipping block = tariff + packaging + 0.50 EUR process buffer
What usually gets missed
- Packaging is not modeled per shipment.
- Tariffs are compared without tracking risk.
- One flat assumption is applied to all categories.
Operational rule for sellers
- Define fixed parcel profiles per category.
- Compare DHL and Hermes monthly using the same profiles.
- Approve prices only when target margin remains after shipping block.
