For those of you who wanted to know how my summer went here it is…
Short answer: GREAT!
At the end of May right before school ended, I got in contact with the president of the local chamber of commerce. After several e-mails I was able to meet her and got some wonderful help and advice. I was able to work some with the chamber this summer and also provided cupcakes for one of their events in June. I met several great people and got a lot of advice plus several orders from the chamber of commerce members. I kept busy with orders this summer without having the business take over my whole life; I still went on a short vacation, hung out at the pool and had some fun besides making cakes. I have found out that word of mouth or meeting face to face with people is usually my best way to get orders. I also took the advice of several people on here to market as a limited time.
Because I had a well calculated business plan, a timeline for what to do before school was out and business started so that I was ready to go and make the most of the whole summer, correct pricing i.e. knowing all my costs for food, overhead, packaging, monthly expenses, etc., what I would make and not make such as no licensed characters or making less than a dozen cupcakes, I had a great summer and a successful business. I did have to turn down a few orders for various reasons and because I had correct pricing for my product I know it was out of some people’s budgets but, I didn’t try to change my policy just for one more order. At the end of the summer, I have paid myself for my start up expenses and also made money.
Thanks to the advice I got here did make the right decision to not try to hide my age even though I was still a little afraid I might sound like I was using it like a crutch. I tried to tell people more like “you should buy my cake because it’s good, and in case you’re wondering I’m also fifteen” instead of “I’m fifteen so you should buy my cake, and it’s also good”. I think I succeeded at that but I did find out it was a little easier to tell people I was in high school and then if they asked further, which most of them did, tell them my actual age. Thanks for all the awesome advice on this thread and all the other forums! And in case any of you are wondering, I'm planning on doing this again.
