Writing a business plan?

Do you remember the first mistake you made creating a business plan? 

If you smiled a little, great. It means you’ve overcome it, and you understand that entrepreneurs make business plan mistakes all the time—and continue to learn from them.

However, there are certain mistakes no business owner should make in their plan to achieve their dreams.

So, in this article, we’ve listed 13 common business plan mistakes you can avoid to get ahead in the game. But before we dive in…

What is the biggest mistake when creating a business plan?

One of the most grave business plan mistakes is having no business plan!

With no business plan, what’s your purpose, and how will you let the world know your intentions? 

You don’t necessarily need to put it down on paper. But there has to be some kind of planning. Much like a north star, planning will give you direction.

Moreover, investors or clients will want to see a plan sometime down the line. Clearly, planning and documenting the plan is inevitable.

So, create a business plan. It can be a one-page business plan or a detailed one—either way, it’ll capture the essence of your vision.

13 common business plan mistakes to avoid

Now that you know you can’t escape a business plan, let’s check out the mistakes you can escape while creating a solid business plan:

1. Poor planning

The business of business planning is no joke. You can’t have a business plan in place just for the sake of it.

It has to have value—information that shows product or service viability, company details, projections, etc.

Why? Poor business planning can imply that:

  • Your great idea isn’t so great because you haven’t thought it through.
  • You don’t care enough, which can be unattractive for investors and banks. (You don’t want to miss out on the money.)
  • You’ll witness scope creep, where stakeholders may want to add new objectives even when the project is underway. (Not fun, is it?)

So, spend time planning, and you’ll naturally make fewer mistakes.

2. Poor executive summary

You and your business have 7 seconds to make an excellent first impression. Since an executive summary is the first impression, you don’t want to gamble with its quality.

A poor executive summary will instantly make clients and investors disinterested in your business plan—a big mistake.

So how do you fix it?

First, make it straightforward so anyone without a business background can get a clear understanding of your business idea.

Second, ensure it’s concise. Briefly mention all the important information, including:

  • Business purpose
  • Company description
  • Market analysis
  • Business goals, competition
  • Financial plan

This will keep your clients or investors interested in learning about the rest of your business plans.

Lastly, don’t be shy about your intentions.

Is your focus on securing enough money for business operations? 

Ensure to include your cash flow table, the money you wish to borrow, and the financial projections to back up your success claims. This way, investors know you mean business and appreciate transparency right off the bat.

A bad executive summary can be worse than having any executive summary

3. Targeting the wrong audience

Obviously, your business doesn’t target everyone in this world. So, define your target market and potential customers. This way, you can write using the vocabulary and tone that best resonates with them.

After all, you want them to understand what your business is about.

However, that’s not enough!

When you write a business plan, you also want to show your work on how you decided on your target market and how you plan to appeal to them. This is more to impress your potential investors.

4. Not doing enough research

When you create a business plan without enough research, you’re hampering your success even before you’ve started your business.

  • Imagine being unaware of your target market or closest competitors.
  • Imagine having yet to think of the most obvious and effective marketing strategy.
  • Imagine having an outdated sales technique.

Now, imagine potential customers or investors realizing these research gaps in your business plan.

One word: Nightmare!

It only shows you’re not prepared.

Hence, remember to carry out in-depth research so there’s nothing that can discredit your business idea.

5. Unrealistic financial projections

Another common mistake is to be unrealistic or overconfident about your earning projections.


Being unrealistic shows that you either don’t understand your business or aren’t qualified enough to make accurate projections.

The result? Banks and lenders won’t trust you or your business idea.

Moreover, unrealistic financial projects are also your one-way ticket to bankruptcy.

So the point is: Be as realistic as possible to gain inventors’ trust and launch a successful business.

6. Ignoring the competition

A good, detailed business plan never ignores competition because there can be serious consequences.

Here’s everything you can’t highlight without proper competitive analysis:

  • What makes you unique?
  • What strategy will help you beat your competitors?
  • How will you grow your credibility?

These aspects are important for your business to avoid becoming complacent and convince investors and partners that you can survive in this saturated market.

7. Poor marketing strategies

Poor marketing strategies can hurt your own company in many ways, including:

  • Reduced sales or profit
  • Increased expenses
  • Market your product or service to the wrong audience
  • Confuse customers about your brand and business idea
  • Drop in product or service prices resulting in financial loss
  • Lose customers to competitors

Scary list, isn’t it?

These pitfalls are why you shouldn’t make the mistake of creating lousy marketing strategies.

8. Not highlighting your team’s unique skills

Many entrepreneurs make this mistake because they often forget the company isn’t just them but their team and what they bring to the table.

So, it’s only right to mention the experience and skills of their top team in a business plan. They should also include how their team plans to achieve the business goals and overall success.

9. Poor writing and presentation

Imagine presenting a business plan with serious ideas, ambitions, profit predictions, etc. But uh-oh. You notice the spelling of ‘projections’ is missing a ‘j,’ and the color scheme is off on one of the pages.

This is a major red flag and an embarrassing mistake that can cost potential clients!

Don’t worry, it’s fixable. Just double-check your spelling and proofread like your life depends on it.

10. Incomplete or missing information

A business plan is your business’s backbone. Missing any important information is like missing a disc in the spine. You’re bound to crumble.

The solution? Check your business plan multiple times to spot such mistakes.

Let others take a look as well. A fresh perspective can spot more missing information.

11. Adding too much information

Less is more. A cliche you want to employ while writing a business plan.


Investors want a clear understanding of whether you understand your business thoroughly. They can do that with just a few crisp pointers in your business plan.

In fact, visuals speak more than words. So, incorporate charts and graphs to reduce the wordiness and get your point across.

To showcase your in-depth analysis and knowledge of your business, include longer, data-heavy information like financial projections and market research in your business plan’s appendix.

12. Being inconsistent

Focus on the consistency of your business plan’s key elements and all sections.

You don’t want to say your company predicts x amounts of profit in the executive summary only to mention y amounts of profit in the financial projections section.

Such inconsistency will only show under-preparedness to your investors—a major red flag.

13. Unclear exit strategy

A clear exit strategy is almost like a medical cover you ought to have.

When things go south (business struggles), you can’t limit your losses without a clear exit strategy.

There’s also an upside to this strategy. If your business booms, you profit significantly by selling your company shares. Either way, you’re covered!
