A letter of credit (L/C) is one of many methods to provide protection to both parties involved in international transactions. L/C is a crucial part of the recipe when it comes to trade done outside borders. These documents have many useful features that make imports and exports easier and more reliable. The letter of credit (L/C) is grounded on international trade practices and regulations. It establishes what the parties are expected to do, what documents are required for the transactions, and the terms both exporter and importer agree beforehand. A letter of credit works as a guarantee that the transaction will be done as agreed.
