What do you need to get your business rolling/growing, and what will it cost? This is arguably the most painful part of business planning. Yet, what is the point of having a plan if you don't know how it all adds up financially? You may not know how to put all the numbers together on your own. If that's the case, invite or even hire someone to help you sort out the numbers. Aside from any potential revenues earned from sales of your product or service, you'll need to know your fixed expenses _ what it costs you to run your business whether or not you sell a single item, and your variable expenses _ what it costs you for each item sold. Naturally, in the early stages of planning a business, you will be doing a lot of forecasting, and your numbers may not be as accurate as you'd like them to be. So, you'll want to be as conservative as possible about how much revenue you'll generate and how much your business will cost to run.
A plan like this would show you how much sales your business would need to do, what your fixed and variable expenses would be, what your material cost, labor cost and profit would need to be to provide the income and profit margin you want. You can see pretty quickly if it's possible for you to get your business to that level. I don't know of any better way than to have your business give you the income and profit you want. What's neat is you can determine what you want your income to be and your profit to be over the next few years and develop a plan that can show you exactly what your business would need to do to give you that income and profit. And with just a little more data you can actually determine how many customers you would need for each year you plan for and how many leads you would need. From that you can actually determine what size market you would need and whether your market is big enough to supply those leads that could be converted into customers.
