Combined vs separate demurrage and detention

The contract gives 10 days combined D&D. The invoice applies 5 demurrage then 5 detention separately, so the container pays detention from gate-out even though combined free time had days left.

What the agent does

  1. Read whether the contract specifies combined or separate free time
  2. Build the timeline from discharge to empty return
  3. Recompute under the combined rule and show where the invoice splits it

What you get back

Dispute file with the combined-clock computation; letter draft.
