Ziad K. Abdelnour, President & CEO Blackhawk Partners, Inc, the New York_based advisory firm on such matters, puts it this way: "Giving a Letter of Intent only means 'Yes I'm intent to buy the goods but I can change my mind anytime.' A letter of Intent is not a binding contract. [Hence] The Letter of Intent is a total waste of time on a worthless piece of paper."
But intentions are not binding contractual conditions. Nor need they lead up to binding contractual conditions. Moreover a letter expressing intent, in its form, does not adequately suggest what the appropriate response should be. Whereas a Request for Quotation / RFQ quite literally is a Request. For a Price Quotation. Hence the document's name, it meaning is expressed by it's name. Hence an appropriate response, for a vendor or supplier, is issuing a a price quote.
