There are no set qualifications for being a caterer besides whatever your local government decides. Some regions do not allow catering out of a home kitchen, so it is best to check with your local Board of Health before setting up yours. Despite the lack of qualifications, there is a lot that you can gain from taking a couple of food management classes. They will help you organize finances and price services. To get additional help, caterers join the National Association of Catering Executives. This association offers Certified Professional Catering Executive certification, business classes and event coordinating workshops. You’ll be able to put your client’s mind at ease when you show credentials. Don’t flap open your wallet like you’re with the FBI though. There’s no reason to get overly dramatic about it.
