So let's sum things up: The LOI and similar documentary terms, are non standard, confusing, and lead to ambiguity. Documentary ambiguity is referred to in trade law as a condition "The Battle of the Forms" in which confusion from contradictory and ambiguous forms and documents damages the transaction. This should be avoided. To seasoned corporate traders and bankers, using terms like "Letter of Intent" is the mark of amateurs. What you properly want is an RFQ, request for quotation, from a seller or supplier. The seller may then reply to your RFQ with a quote OR full offer if they wish.
Next you will mention the date. The next stage is the body paragraphs. In the body paragraph you are supposed to state why do you intend to buy the business? What synergies can be created from takeover and how can you grow the business in future? What is the price range you are willing to pay for the business? Who are the people who intend to buy the business? These are some of the basics things you will be required to mention. letters of intent can be altered according to the user's requirements.
