Eat what you kill is the business philosophy that a person who accomplishes something should get the full financial benefit that results from that accomplishment.

“论功行赏”是指，完成某项任务的个人应该得到该任务带来的所有经济利益这样一种商业哲学。

Example：

We are current using an “eat what you kill” compensation system in our firm.

我们公司现在采用的是论功行赏的薪酬制度。
