In essence, here is a great way to think of superior business planning. Imagine you are taking a road trip from California to New York. No planning ("flying by the seat of your pants") would involve you getting in the car and driving "East" on every freeway you come across. Adequate planning would involve mapping out your course, planning where to stay overnight, where to eat, sights to see, and so forth.
Marketing Plan : There are many different catering niche markets. Before you start your marketing efforts it is important to have a good idea of your menus and the niches that you are targeting. Try to identify a gap in the market that is not being met by other caterers and go after it. Once you have a better idea of what you are selling you can then look at how you can sell it effectively. Start by packaging your offerings nicely into menus, brochures and a website. Then work out a system for pricing catering jobs profitably.
Executive Summary : This is basically an introduction where you can summarise the other sections of the report and give a very basic outline of what the proposed business is about.
Startup Costs and Considerations: List out startup costs and initial operating costs and then calculate the total amount of startup capital that is required before you can open your doors to clients. Make a note of the sources of funding that are available to you and the advantages and disadvantages of each option.
