That’s antithetical to “this period’s bonus.” Who cares if it dies in three months when the bonus for that three months end up in the salesman’s pocket?
That’s not how it works, you structure the comp such that the sales person doesn’t get paid out in this case.
Why would you be paying a bonus for deals that die? Sales incentives need to match business incentives or you’re completely screwed.
