The three basic actions for growing a business in any economic climate are: improve efficiency (maintain output while reducing inputs, such as time and money); increase volume (produce more in order to spread fixed costs); reorganize the business (change goals, methods and/or philosophy). If you plan to implement one of these, you may as well plan to implement them all. By focusing on one of the above strategies, you will find a ripple effect that causes a need to address the others. This is a good thing.
Suggested Retail Price: Base the suggested retail price on comparable market prices and other relative assumptions and factors. For example, if the invention combines the task of two or more existing products on the market, provide the cost of using those products separately and then demonstrate how your invention is priced such that it saves the consumer time and money. A good example is a food processor. You would provide the cost of knives, cutting boards, and the time it takes to cut everything. Whereas your invention, the food processor, is priced less than all of those things combined, plus you have the added value of convenience and time savings.
If an online business, you need to go into detail how you will attract customers to your website. General statements like "I will use Face Book ads and email marketing" will contribute almost nothing to helping your cause unless you have detailed statistical analysis of tests you have conducted or of another similar business you have been associated with. If you do not have any data upon which you reference your estimates, it could show lack of proper thought to the remainder of your business plan.
Explain the fundamentals of the proposed business: What will your product be? Who will your customers be? Who are the owners? What do you think the future holds for your business and your industry? Make it enthusiastic, professional, complete, and concise. If you are applying for a loan, state clearly how much you need and be precise in how you are going to use it. Also include detail about how the money will make your business more profitable, thereby ensuring repayment of the loan.
