Run your local girl scout community events
This is a great way to earn a reasonable profit, and it is for the good of the Girl Scout community. For example if you run the Community Sock Hop, the profit is split between the K/L community, GSHH Council, and your troop.
RUN A BREAKFAST
Generally with a theme. On the weekends people love to go out for breakfast, and if the local Girl Scout Troop is hosting a breakfast, you'll find that the community may come out to support you and eat up!
RUn a carnival
Set up a carnival at your local town park or at the school. Have different stations like bobbing for apples, 3 legged race, balancing an egg on a spoon and racing, tug of war, etc. Charge a fee to come to the carnival and have your troop run each station. The winners of each carnival game can earn tickets which can be used to buy small prizes at the prize table. Oriental Trading is a great source for inexpensive little prizes that kids love. Get each member of your troop to donate a toy or small item, and solicit local business to donate gift certificates or other items, and make gift baskets out of these, each with a theme. Sell raffle tickets for the gift baskets. Finally, serve drinks and snacks (again, donated by parents) and sell them. You will earn money from the entrance fee, the raffle, and the food sales.
Yard Sale
It's easy! Ask your girls to gather up some old stuff to sell. Also a great opportunity to set up a cookie booth!
Car Wash
Get permission to use the parking lot at your school or church/temple and wash cars for $10 per car. It's cheaper than going to the professional car wash, you'll have fun getting wet, and your customer will be helping the Girl Scout Community!
Host a winter fun day for younger kids
Set this up at a local community house. Make a flyer and publicize your event which is targeted at younger children, ages K-5th grade. The event should be about 2 hours long and during this time you can decorate cookies, make candy houses, or make a craft project. We made home-made snow globes and candy houses. Offer temporary tatoos or face painting, Play a rousing game of Twister. You raise funds by charging the parents $15 per child for the event. They can drop them off and go shopping or something while you keep the kids entertained. Make sure you limit the number of attendees to 2-3 children per scout and have a couple of additional adults around to help out.
Make and Sell Dog Biscuits and Cat toys
Generally around Christmas and Valentines day. You can get a recipe online and make these in cute shapes. Wrap them up in cellophane with a ribbon and sell them as stocking stuffers. These also make great donations for your local ASPCA or animal shelter.
Mother Daughter Tea Party
We found a local church that had a large hall and dishes, cups and china and cutlery we could borrow. We made a flyer and sent it around the GSHH community by email. We also advertised in the local paper. Mothers and their daughters came to the tea and our troop went through all the parts of the Manners badge. We made cookies, muffins, and brownies and served them to the younger girls and their moms, while other girls served hot cider, hot chocolate, and coffee and tea for the parents. All the food supplies were donated. The older troop reviewed things like how to properly set a table, using a napkin, saying 'Please' and 'Thank You', and the polite way to decline a food you don't like ("no Thank You"). We charged $20 per couple (mother and daughter) and since all the supplies were borrowed or donated, all of the entry fee was pure profit.
Ice skating For girl scout community
Rent a rink for the night and invite your community. Charge $5 per person over the cost of the rink rental and keep the profit for your efforts.
