Expert Advice: 10 Tips to Craft a Strong Business Plan A business plan writing expert weighs in what to include and what not to include to create a winning business plan.

In their book Write Your Business Plan, the staff of Entrepreneur Media, Inc. offer an in-depth understanding of what's essential to any business plan, what's appropriate for your venture, and what it takes to ensure success. In this edited excerpt, guest contributor Kaye Vivian, an expert in writing business plans, offers advice on how you can improve your business plan content and presentation.

When it comes to content, these 10 tips will help:

1. Know your competition. Be prepared to name them and tell what makes you different from (and better than) each of them. But do not disparage your competition.

2. Know your audience. You'll probably want several versions of your business plan—one for bankers or venture capitalists, one for individual investors, one for companies that may want to do a joint venture with you rather than fund you, etc.

3. Have proof to back up every claim you make. If you expect to be the leader in your field in six months, you have to say why you think so. If you say your product will take the market by storm, you have to support this statement with facts. If you say your management team is fully qualified to make the business a success, be sure staff resumes demonstrate the experience needed.

4. Be conservative in all financial estimates and projections. If you feel certain you'll capture 50 percent of the market in the first year, you can say why you think so and hint at what those numbers may be. But make your financial projections more conservative—for example, a 10 percent market share is much more credible.

5. Be realistic with time and resources available. If you're working with a big company now, you may think things will happen faster than they will once you have to buy the supplies, write the checks and answer the phones yourself. Being overly optimistic with time and resources is a common error entrepreneurs make. Being realistic is important because it lends credibility to your presentation. Always assume things will take 15 percent longer than you anticipated. Therefore, 20 weeks is now 23 weeks.

6. Be logical. Think like a banker, and write what they would want to see.

7. Have a strong management team. Make sure it has good credentials and expertise. Your team members don't have to have worked in the field, but you do need to draw parallels between what they've done and the skills needed to make your venture succeed. Don't have all the skills you need? Consider adding an advisory board of people skilled in your field, and include their resumes.

8. Document why your idea will work. Have others done something similar that was successful? Have you made a prototype? Include all the variables that can have an impact on the result or outcome of your idea. Show why some of the variables don't apply to your situation or explain how you intend to overcome them or make them better.

9. Describe your facilities and location for performing the work. If you'll need to expand, discuss when, where and why.

10. Discuss payout options for the investors. Some investors want a hands-on role; some want to put associates on your board of directors; some don't want to be involved in day-to-day activities. All investors want to know when they can get their money back and at what rate of return. Most want out within three to five years. Provide a brief description of options for investors, or at least mention that you're ready to discuss options with any serious prospect.

And here's what not to include in your business plan:

1. Form over substance. If it looks good but doesn't have a solid basis in fact and research, you might as well save your energy.

2. Empty claims. If you make a statement without supporting it, you may as well leave it out. You need to follow-up what you say in the next sentence with a statistic, fact or even a quote from a knowledgeable source that supports the claim.

3. Rumors about the competition. If you know for sure a competitor is going out of business, you can allude to it, but avoid listing its weaknesses or hearsay. Stick to facts.

4. Superlatives and strong adjectives. Words like "major," "incredible," "amazing," "outstanding," "unbelievable," "terrific," "great," "most," "best" and "fabulous" don't have a place in a business plan. Avoid "unique" unless you can demonstrate with facts that the product or service is truly one of a kind. (Hint: Chances are, it isn't.)

5. Long documents. If readers want more, they'll ask.

6. Overestimating on your financial projections. Sure you want to look good, but resist optimism here. Use half of what you think is reasonable. It's better to underestimate than set expectations that aren't fulfilled.

7. Overly optimistic time frames. Ask around or do research on the Internet. If it takes most companies six to 12 months to get up and running, that's what it'll take yours. If you think it'll take three months to develop your prototype, double it. You'll face delays you don't know about yet—ones you can't control. Remember to be conservative in your time predictions.

8. Gimmicks. Serious investors want facts, not gimmicks. They may eat the chocolate rose that accompanies the business plan for your new florist shop, but it won't make them any more interested in investing in the venture.

9. Amateurish financial projections. Spend some money and get an accountant to do these for you. They'll help you think through the financial side of your venture, plus put the numbers into a standard business format that a businessperson expects.
