Fuel

Fuel is priced as a separate cost component, never blended into the base rate.

The fuel component is derived from current fuel price data and applied to the legs it belongs to. Keeping it separate has one crucial consequence downstream: when an offer is sent, the base can be frozen while the fuel component stays live and re-indexes as the market moves (see Frozen base and indexation).

If fuel were baked into the base rate, every fuel movement would force a renegotiation of the whole price — or worse, silently eat the margin. Separating it makes price changes explainable to the client in one sentence: the base did not move; fuel did, by this many euros.
