Koreans usually say "I got incentive from the company after making a good sales result this month.", but I think it's wrong. "incentive" is some kind of methods to encourage your morale, so it could be anything. When you actually get some bonus or something, you should say "incentive pay(bonus). What do you think?
ex)incentive vs incentive pay(bonus)
If they are going to use "incentive" like that, they should at least say they got "an incentive."
It sounds odd to me. I would say I got a bonus, or an incentive bonus.
