Input Cost Index

The number of days equipment or crews are actively deployed and generating billable revenue on a job site.

Subcontractors hauling equipment or materials to remote sites often negotiate FTL rates to reduce logistics costs. Consolidating loads before mobilisation helps field teams maximise savings under this pricing model.
