What does the checker verify on a document error demurrage cost?

Container check digits against ISO 6346, weight and unit consistency, date coherence, Incoterm and port-code sanity, required-field presence and more — 24 checks in total, each reported with the field it applies to.

Is my document stored?

No. The file stays in memory while it is processed and is never written to disk. The result is deleted automatically within 24 hours, and documents are never used to train models.

How much does it cost?

The first 3 documents every month are free. Paid plans start at $19 per month for 50 documents. A one-off Batch Pack covers 5,000 documents.

The Demurrage Cost of Document Errors

BOLCheck: The demurrage cost of document errors. Free to try on a Bill of Lading, no signup required. Runs on Bill of Lading documents only, with results deleted within 24 hours.

A paperwork error does not stop at the paperwork. When a value on the Bill of Lading does not match what customs or the carrier expects, the container waits — and a container that waits is billed.

How a typo becomes a container on the quay

Customs compares the Bill of Lading against the manifest and the commercial documents. A gross weight that disagrees, or a container number that does not compute, reads as a signal that something about the shipment is not what it claims. The container is held until that is resolved, and by then the clock is already running.

What accumulates while it waits

· Demurrage at the terminal, once the free days are used up
· Storage, which is billed separately from demurrage
· Examination fees if the container is pulled for inspection
· The amendment or reissue needed to correct the original error
· The customer conversation, which costs the most and appears on no invoice

The cheapest place to catch it

Every one of those charges starts with a field that could have been checked in seconds. The device that catches it has to be the one that never gets tired — a misplaced decimal is invisible to the person who typed it and obvious to arithmetic.

What gets checked

33 Bill of Lading fields are looked for, and 24 rules run over them. Every finding names the field it applies to, so it can be fixed in the source document.
