Among Internet based brokers and agents the LOI is commonly advanced as a leading inquiry document. This protocol is utterly incorrect, and misuse of the LOI is often seen by experienced Exporters as a mark of an amateur. Letters of Intent are not standard international business documents, though they do legitimately pop up rarely, much less often than most brokers believe.
You have heard the term "letter of intent" if you have explored International business. However you might find yourself unsure and confused about how it is used.
