There are two main types of letters of credit:
Revocable Letter of Credit:
This type of letter of credit can be cancelled or
modified by the issuing bank at any time without
prior notice to the beneficiary (seller). However, this
type of letter of credit is rare and not widely used.
Irrevocable Letter of Credit:
This type of letter of credit cannot be cancelled or
modified without the agreement of all parties
involved, including the beneficiary, the issuing
bank, and the buyer. This provides a level of
security to the seller that they will be paid for their
goods or services, as long as they meet the
conditions specified in the letter of credit.
