I don't know if there is someone here that I have heard about kill fee. It is one of the terms that freelancers should put in tjer contracts whenever they want to have agreements with clients. It states that freelancers should be paid, in fact, full, whenever the clients cancel the deal abruptly. This is to safeguard the freelancers. For many reasons, clients may decide to cancel the tasks. This should not affect the freelancers.
