Describes a situation, number, or task that has reached a natural, convenient, or tidy stopping point. Often used when something can be cleanly divided, finished, or paused without awkwardness.

この金額はキリが良くないので、もう少し値引きしてほしい。
This amount isn't a nice round number, so I'd like a little more discount.
Almost synonymous; キリの良い is the attributive form (modifying a noun), while 切りがいい is the predicative form (ending a sentence). Both mean 'a good place to stop' or 'conveniently divisible'.
From 切り (kiri, 'cut, end, pause') + が + いい (ii, 'good'). Literally 'the cutting is good', referring to a point where something can be cleanly stopped or divided.
