When you have your own business, you have to think of everything from advertising to exit signs. There are the regular monthly expenses such as rent, utilities, and insurance, of course, but then there are all the little details that can add up.

If you are thinking of starting your own business, do some brainstorming. I would suggest making a comprehensive list of everything you will need. Then check around for the best prices!
