Maritime document processing is not one task. The bill of lading has to agree with the cargo manifest and the mate’s receipt. The dangerous goods declaration has to agree with the IMDG Code entry and the stowage plan. The statement of facts has to agree with the notice of readiness and the port log, because laytime and demurrage are calculated from it under the charter party. Each is produced by a different party, in a different format, often as a scan.
The value is in the cross-check. A clean bill of lading issued against a mate’s receipt with remarks, a container count that differs between manifest and bill, a time in the statement of facts that is not in the log: each is a future dispute. Finding them while they can still be corrected is cheaper than arguing them later.
