The UCC is more liberal than the common law in allowing contracts to be formed despite counteroffers and in incorporating the counteroffers into the contracts. This UCC provision is necessary because the use of routine forms for contracts is very common, and if the rule were otherwise, much valuable time would be wasted by drafting clauses tailored to the precise wording of the routine printed forms. A buyer and a seller send out documents accompanying or incorporating their offers and acceptances, and the provisions in each document rarely correspond precisely. Indeed, it is often the case that one side’s form contains terms favorable to it but inconsistent with terms on the other side’s form. Section 2-207 of the UCC attempts to resolve this “battle of the forms” by providing that additional terms or conditions in an acceptance operate as such unless the acceptance is conditioned on the offeror’s consent to the new or different terms. The new terms are construed as offers but are automatically incorporated in any contract between merchants for the sale of goods unless “(a) the offer expressly limits acceptance to the terms of the offer; (b) [the terms] materially alter it; or (c) notification of objection to them has already been given or is given within a reasonable time after notice of them is received.”
An example of terms that become part of the contract without being expressly agreed to are clauses providing for interest payments on overdue bills. Examples of terms that would materially alter the contract and hence need express approval are clauses that negate the standard warranties that sellers give buyers on their merchandise.
Frequently, parties use contract provisions to prevent the automatic introduction of new terms. A typical seller’s provision is as follows:
