The Idea in Brief

You’ve got a great idea for a new product or service—how can you persuade investors to support it? Flashy PowerPoint slides aren’t enough; you need a winning business plan. A compelling plan accurately reflects the viewpoints of your three key constituencies: the market, potential investors, and the producer (the entrepreneur or inventor of the new offering).

But too many plans are written solely from the perspective of the producer. The problem is that, unless you’ve got your own capital to finance your venture, the only way you’ll get the funding you need is to satisfy the market’s and investors’ needs.

Here’s how to grab their attention.

The Idea in Practice

Emphasize Market Needs

To make a convincing case that a substantial market exists, establish market interest and document your claims.

Establish market interest. Provide evidence that customers are intrigued by your claims about the benefits of the new product or service:

  • Let some customers use a product prototype; then get written evaluations.
  • Offer the product to a few potential customers at a deep discount if they pay part of the production cost. This lets you determine whether potential buyers even exist.
  • Use “reference installations”—statements from initial users, sales reps, distributors, and would-be customers who have seen the product demonstrated.

Document your claims. You’ve established market interest. Now use data to support your assertions about potential growth rates of sales and profits.

  • Specify the number of potential customers, the size of their businesses, and the size that is most appropriate to your offering. Remember: Bigger isn’t necessarily better; e.g., saving $10,000 per year in chemical use may mean a lot to a modest company but not to a Du Pont.
  • Show the nature of the industry; e.g., franchised weight-loss clinics might grow fast, but they can decline rapidly when competition stiffens. State how you will continually innovate to survive.
  • Project realistic growth rates at which customers will accept—and buy—your offering. From there, assemble a credible sales plan and project plant and staffing needs.

Address Investor Needs

Cashing out. Show when and how investors may liquidate their holdings. Venture capital firms usually want to cash out in three to seven years; professional investors look for a large capital appreciation.

Making sound projections. Give realistic, five-year forecasts of profitability. Don’t skimp on the numbers, get overly optimistic about them, or blanket your plan with a smog of figures covering every possible variation.

The price. To figure out how much to invest in your offering, investors calculate your company’s value on the basis of results expected five years after they invest. They’ll want a 35 to 40% return for mature companies—up to 60% for less mature ventures. To make a convincing case for a rich return, get a product in the hands of representative customers—and demonstrate substantial market interest.

A comprehensive, carefully thought-out business plan is essential to the success of entrepreneurs and corporate managers. Whether you are starting up a new business, seeking additional capital for existing product lines, or proposing a new activity in a corporate division, you will never face a more challenging writing assignment than the preparation of a business plan.
