We have multiple budgets set up in our system that all feed up to one funding source. Sometimes we need to go over in one budget and account for it by going under in another. There is a pop up box that comes up that says something along the lines of "funds will be taken from the funding source" but the overage is never actually reflected anywhere. We also got to the point this year where we had to increase our budget in order to distribute more grants from it. It would be helpful when setting up the budget to provide an option to go negative on a budget so that the budget doesn't need to be changed. That way you have an accurate representation of how budget lines were utilized. Note that we process our own payments so this may not work for those who use Blackbaud to process payments. But it would be nice to have the option on set up.
