Usage notes

Primarily used in two contexts: firstly, to cut off further discussion – “You are not going to marry him – that is non-negotiable!”; secondly, it is printed on pay slips and other payment advice forms (forms that indicate that a payment has been made) to avoid confusion with checks (formally, to indicate that it is informative, and not a negotiable instrument).
