The hardest part of organizing a back to school fundraiser is at the beginning, when you are assessing needs and searching for a school fundraiser idea. The fun part comes later, when you get the kids involved and watch their energy take over, but don't put the cart before the horse, because there's still some work to do first. You need to think about the size of your back to school fundraiser team, and how much money you need to raise in total. It would also be helpful to know what sort of funds are already available. If the group has an existing account they can use as investment money, you could go for something like a direct sale back to school fundraiser, like scratch cards or pizza cards. These card-based back to school fundraisers are great for profit, as you can make up to 90% depending on how many cards you can commit to buying upfront.
A back to school fundraiser can be a lot of fun, but don't underestimate the work involved. Have a couple of meetings in August with parents, the relevant teacher, and maybe even the team or club members, so that everyone is on the same page with regard to what is expected of them and what will have to be done. With a strong foundation of organization, you've already taken the biggest step toward a successful back to school fundraiser.
