A business plan should be detailed. In listing your products and services for example, you should not really stop by just enumerating them. You also should write down the descriptions and scope of your products and services, touch base on production and identify means on how you can market your "brain - child" to your targeted niche.
Ownership and Management : This section of your catering business plan should suggest whether you intend to structure your business as a sole proprietorship, a partnership or a limited liability company. If the business will have multiple owners then you should set out clearly what their respective interests will be and the role that they will play in the management of the business.
Outline all of the other hurdles that must be overcome before you can start operating as a catering service. Depending on the requirements in your state or country you will have a number of licenses and permits to obtain. You may even have to do a short course to get certified in food management or hygiene. It is important to set out the costs involved as well as a time frame for compliance with these local regulations.
It needs to have a list of everything you need. Note that the word everything here comprises of the equipment, technology, raw materials, financial and other resources that you may need when starting and running your business venture. Having all these listed will give you an idea on how much capital you need before you start and how much money should you make in a day to make your business survive.
