Advising bank establishes authenticity of the letter of credit by cryptographic means or signature books, then informs seller (beneficiary). Advising bank MAY confirm L/C, i.e. add its own payment undertaking.
Seller should now check that L/C matches commercial agreement, and that all its terms and conditions can be satisfied, (e.g. all documents can be obtained in good time.) If there is anything that may cause a problem, the buyer must be asked to issue an AMENDMENT
Seller ships the goods, then assembles the documents called for in the L/C (invoice, transport document etc.) Before presenting the documents to the bank, the seller should check them for discrepancies with the L/C, and correct the documents where necessary.
