Transportation Rates

Transportation rates help Darwin model logistics more realistically. Instead of hiding delivery costs inside arbitrary unit-price adjustments, transportation rates keep logistics assumptions visible and structured.

Why Transportation Rates Matter

Transportation cost can vary by:

Distance
Supplier location
Delivery conditions
Project geography

Keeping these rates structured improves traceability and makes pricing less fragile.

How They Work

Transportation rates are maintained in the configuration area and can be linked to expenses within modules. When a module includes logistics-driven expenses, the transportation rate provides the cost basis for delivery and handling.

Best Practices

Define transportation rates for the regions and supplier locations you work with
Update rates when fuel costs or delivery terms change
Link transportation rates to relevant expenses rather than embedding flat amounts
Review rates periodically to ensure they reflect current market conditions
