Qualified acceptance is a type of acceptance where the acceptance is subject to a condition. Qualified acceptance is a sort of counteroffer. Qualified acceptance brings in variations to the sum, mode, or place of payment in a contract. (USLegal)

Conditional Acceptance A conditional acceptance, sometimes called a qualified acceptance, occurs when a person to whom an offer has been made tells the offeror that he or she is willing to agree to the offer provided that some changes are made in its terms or that some condition or event occurs. This type of acceptance operates as a counteroffer. A counteroffer must be accepted by the original offeror before a contract can be established between the parties.
