The most important aspect of business planning (the "What does it all come down to?" part), however, is spending the time to do your research ("due diligence") and critically thinking about these various aspects of your business. Of course, it is impossible to anticipate every detail simply by spending time thinking and writing; it is for this reason that plans are referred to and viewed as "dynamic". However, the more issues and scenarios you are able to come up with ahead of time, the more prepared you will be to handle these as they arise.
Once you start your catering business it is important to continue to refer to your business plan to make sure that you remain on track to meet your goals. You can also make changes to it if necessary as your business develops.
Outline any competitive advantages that you may have. Do you have any catering business qualifications or skills? Have you have experience in the hospitality industry? Do you have existing relationships with suppliers or prospective clients?
Financial Planning : Perhaps one of the most important parts of any business plan is the financial plan. You need to make some forecasts of revenue and expenditure over a period of several years. You can then estimate when you will reach a break even point and how much profit will be possible in the future. Set out anticipated monthly cash flows in a spreadsheet program on your computer. As businesses often don't grow as fast as their owners expect them to you should outline several scenarios. One scenario can show your expected outcome, one can show a more optimistic forecast and the third one can show a worst case scenario.
