What it means
The invoice is the commercial snapshot of the contract for that shipment. It should use the legal names that KYC established, the goods description that can survive customs and the LC, and the Incoterm with named place that was actually priced.
Where invoice mismatches stop the file
Most documentation failures start here: a trading style on the invoice and a legal name on the LC; a nickname for the product that does not match the HS heading; a CIF invoice that still reads FOB. Those are not typing errors at the port. They are file errors.
What it does not cover
Proof of loading (that is the transport document). Lab results (COA). Origin in every scheme (a separate certificate may still be required). Insurance cover notes.
Common mistakes
Unit prices that cannot be reconciled to the contract. Missing Incoterm place. Descriptions too vague for customs and too creative for the LC. Invoicing a different entity than the one that was screened.
