Carrier note

Use this term in context with the rate confirmation, broker communication, facility instructions, and billing paperwork. A short definition is useful, but the written load terms control the actual freight decision.

Carrier example

The receiver requires a lumper payment before releasing paperwork, so the carrier asks how reimbursement should be approved.

Common mistake

Paying the lumper first and asking whether it is reimbursable later.

Paperwork note

Keep lumper receipt, approval message, payment code if used, POD, BOL, and invoice note together.
