An offer refers to a promise that is dependent on a certain act, promise, or forbearance given in exchange for the initial promise. It is a demonstration of your willingness to enter into an agreement and an invitation to the other party to conclude the agreement by expressing assent. Determining whether a party has actually made an offer is a common challenge in a contract case. As a rule of thumb, the offer must be definite and reasonable enough for the receiving party to believe that it is indeed an offer. If your offer includes terms such as quantity, price, quality, and place and time of delivery, the court may find that you have indeed made an offer.
