The importer goes to his bank to have a Letter of Credit drawn up in favor of the exporter. The importer's bank fixes an L/C amount (credit opening) under specific conditions. The issuing bank then sends the Letter of Credit to the advising bank. The banks use the international means of communication SWIFT for this. The exporter's bank checks the Letter of Credit. If approved, he sends this to the exporter with an advisory letter. This completes the process at the bank. The documents must meet the LC conditions in order to obtain an irrevocable commitment to payment. If the conditions are met and approved by both banks, the payment by the exporter becomes final.
