What is the difference between a letter of intent and a contract?
A letter of intent (LOI) allows early works to start before a formal contract is executed, but it doesn’t always create binding obligations. A contract, however, is a legally enforceable agreement once all essential terms are agreed.

If it includes clear scope, price, and intent to be bound, it can form a binding contract even if the full contract isn’t signed.
