The 4 Types of Business Plans Learn which of these four business plan formats best fits your needs.

In their book Write Your Business Plan, the staff of Entrepreneur Media 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, the authors describe four different types of plans you could write and what you'd use each one for.

Business plans can be divided roughly into four distinct types. There are very short plans, or miniplans, presentation plans or decks, working plans, and what-if plans. They each require very different amounts of labor and not always with proportionately different results. That is to say, a more elaborate plan isn't guaranteed to be superior to an abbreviated one. Success depends on various factors and whether the right plan is used in the right setting. For example, a new hire may not want to read the same, elaborate version of your plan that might be important to a potential investor.

The Miniplan

The miniplan is preferred by many recipients because they can read it or download it quickly to read later on their iPhone or tablet. You include most of the same ingredients that you would in a longer plan, but you cut to the highlights while telling the same story. For a small-business venture, it's typically all that you need. For a more complex business, you may need the longer version.

The Presentation Plan

The advent of PowerPoint presentations changed the way many, if not most, plans are presented. And while the plan is shorter than its predecessors, it's not necessarily easier to present. Many people lose sleep over an upcoming presentation, especially one that can play a vital role in the future of their business. But presenting your plan as a deck can be very powerful. Readers of a plan can't always capture your passion for the business nor can they ask questions when you finish. But in 20 minutes, you can cover all the key points and tell your story from concept and mission statement through financial forecasts.

Remember to keep your graphics uncluttered and to make comments to accentuate your ideas rather than simply reading what's in front of your audience.

While a presentation plan is concise, don't be fooled: It takes plenty of planning. The pertinent questions who, what, where, why, when and how all need to be answered.

The Working Plan

A working plan is a tool to be used to operate your business. It has to be long on detail but may be short on presentation. As with a miniplan, you can probably can afford a somewhat higher degree of candor and informality when preparing a working plan. In a plan you intend to present to a bank loan committee, you might describe a rival as "competing primarily on a price basis." In a working plan, your comment about the same competitor might be "When is Jones ever going to stop this insane price-cutting?"

A plan intended strictly for internal use may also omit some elements that you need not explain to yourself. Likewise, you probably don't need to include an appendix with resumes of key executives. Nor would a working plan especially benefit from product photos.

Internal policy considerations may guide the decision about whether to include or exclude certain information in a working plan. Many entrepreneurs are sensitive about employees knowing the precise salary the owner takes home from the business. To the extent such information can be left out of a working plan without compromising its utility, you can feel free to protect your privacy.

The What-If Plan

When you face unusual circumstances, you need a variant on the working plan. For example, you might want to prepare a contingency plan when you're seeking bank financing. A contingency plan is a plan based on the worst-case scenario that you can imagine your business surviving—loss of market share, heavy price competition, defection of a key member of your management team. A contingency plan can soothe the fears of a banker or investor by demonstrating that you have indeed considered more than a rosy scenario.

Your business may be considering an acquisition, in which case a pro forma business plan (some call this a what-if plan) can help you understand what the acquisition is worth and how it might affect your core business. What if you raise prices, invest in staff training and reduce duplicative efforts? Such what-if planning doesn't have to be as formal as a presentation plan. Perhaps you want to mull over the chances of a major expansion. A what-if plan can help you spot the increased needs for space, equipment, personnel and other variables so you can make good decisions.

What sets these kinds of plans apart from the working and presentation plans is that they aren't necessarily describing how you'll run the business. They're essentially more like an addendum to your actual business plan. If you decide to acquire that competitor or grow dramatically, you'll want to incorporate some of the thinking already invested in these special purpose plans into your primary business plan.
