Why is proof of delivery the most important document at the end of a freight transaction?

Proof of delivery is the document that legally closes a freight transaction — it confirms the named consignee received the cargo in the condition described on the CMR consignment note. Under CMR Article 30, if the receiver signs the proof of delivery without noting reservations, the cargo is presumed delivered in correct condition and damage claims become substantially harder to establish after that signature. Go Trans monitors proof of delivery confirmation from the carrier at the end of every consignment — the signed delivery record is the final milestone before the booking is closed in the tracking system.
