RallyUp gives you the option of setting a goal when building your fundraising campaign, but you don't have to reach that goal to receive the funds that you raise. Regardless of how much you raise, the nonprofit or charity beneficiary will receive the funds.
Setting a goal is just a simple way to let your donors know how much you want to raise, and how close you are to reaching it!
