5 Common Mistakes First Time Business Authors Make and How to Avoid Them

Writing a business book can be one of the most exciting—and let’s be real, intimidating—projects you’ll ever take on as an entrepreneur. You’re putting your expertise into words, sharing your story, and creating something that can live on your website, your podcast, and in your clients’ hands for years to come.

But even the smartest, most capable business owners make mistakes when writing their first book. The good news? Every single one of these mistakes is totally avoidable. Let’s talk about what they are and how to steer clear, so your book actually works for your business.

Mistake #1: Not Getting Clear on Your Goal

Before you write a single word, you’ve got to ask yourself: What’s the purpose of this book?

Is it to bring in new clients, boost your credibility, open up speaking opportunities, or serve as a companion to your course? If you don’t define that goal from the start, your book can end up feeling a little scattered—and it won’t move the needle in your business the way you hoped.

Take some time to clarify your “why.” The clearer you are on your book’s purpose, the more intentional (and strategic) your writing will be.

Mistake #2: Trying to Write for Everyone

If you’re trying to write a book that speaks to everyone, it’s probably going to connect with no one. Your ideal reader—the client you love working with most—is the person your book should be written for.

As Amy Porterfield says, if you have an ant problem at your house and you go to the store and see a can of bug spray and a can of ant spray, we all know you’re reaching for the ant spray. (even if the bug spray is for termites, wasps, roaches, and ants.) Be specific on who your book is for and your target audience will respond.

Think of your reader like your favorite client. What are they struggling with right now? What transformation are they craving? When you write directly to that person, your book becomes magnetic to the right audience (and makes your offers an easy next step).

Mistake #3: Skipping the Planning Phase

I get it—you’re busy. You’ve got a business to run and probably feel you don’t have time to outline every chapter in detail. But skipping this step is like trying to build a house without a blueprint. You might get there eventually, but it’ll take twice as long and cause way more frustration. It can also cost you more when you get to the editing step. I’ve seen this a lot—don’t go down that road. It pays to do your homework.

You’ll want to research your title or any key named ideas in your book. You don’t want your whole book to be based on say, the WAVE method, (where each letter stands for a step in your uniques process) when there is already a book by that name, the author has 75K followers, and her philosophy is completely opposite your own. You’ll end up rewriting your whole book. Yup, I’ve seen it.

A solid outline is your best friend. It gives you structure, direction, and the freedom to focus on your ideas instead of worrying what comes next. This will help you, not only with the writing process, but you’ll be able to get everything into your first draft and not have to address gaping holes after developmental editing.

Mistake #4: Skimping on Editing and Professional Support

You wouldn’t walk on stage to deliver a keynote without rehearsing and tightening your message, right? The same goes for your book. Editing isn’t just about catching typos—it’s about sharpening your message, making sure your ideas flow, and helping you sound like you at your best.

We all know that self publishing has not always had the best reputation, because of sloppy work and a lot of books looking unprofessional. This is because some indie authors skip editing. I know I’m biased as an editor myself, but please save yourself from embarassment. Hire a good editor. Bringing in a professional editor is one of the smartest investments you can make. Your credibility depends on it.

Mistake #5: Treating Your Book Like a Standalone Project

Your book is not just a creative side project—it’s a business tool. I see so many first-time authors pour months into writing but never think about how the book fits into their larger marketing or sales strategy.

Your book should connect naturally to what you offer—whether that’s a course, coaching, a service, or consulting. When done right, it becomes a powerful lead magnet and authority-builder that keeps bringing in clients and collaborators long after launch day.

Avoiding These Mistakes = A Stronger, Smarter Book

Here’s the bottom line: writing your first business book doesn’t have to feel like wandering in the dark. With a clear purpose, a plan, and the right guidance, you can create a book that elevates your authority and grows your business for years to come.

Frequently Asked Questions About Writing Your First Business Book

What are the biggest mistakes first-time business book authors make? The most common mistakes are skipping the planning phase, writing without a clear goal, and trying to appeal to everyone instead of a specific reader. Many first-time authors also underestimate how much professional editing matters—not just for catching typos, but for making sure the book actually works as a business tool.

Do I need to outline my book before I start writing? Yes. And skipping this step is one of the most expensive mistakes you can make. A solid outline saves you time, prevents structural problems, and reduces your editing costs significantly. Authors who skip outlining often end up doing major rewrites after developmental editing. That costs real money and real time.

How do I know if my book idea is original enough? Before you build your entire book around a named concept, method, or framework, research it. Search Amazon, Google, and social media to make sure another author hasn't already claimed that name, especially if they have a large following or a conflicting philosophy. Finding this out after writing your manuscript is a painful and costly surprise.

What's the difference between editing types, and do I need all of them? Most nonfiction business books benefit from at least two rounds: developmental editing (big-picture structure, flow, and messaging) and line or copy editing (sentence-level clarity and polish). Proofreading catches what's left. Skipping editing entirely is the fastest way to undermine your credibility as an expert—even one embarrassing error can stick in a reader's mind.

How much does it cost to hire a professional book editor? Editing costs vary depending on the type of editing and the length of your manuscript. Developmental editing typically runs higher than copy editing or proofreading. The investment is worth it—your book represents your expertise and your brand, and readers will judge both by the quality of the final product.

How does a business book help me get more clients? When written strategically, a business book establishes your authority, attracts your ideal clients, and connects naturally to your other offers: coaching, courses, consulting, or speaking. It works for you long after launch day, bringing in leads and opening doors that a social media post simply can't.

When should I hire an editor for my business book? Ideally, bring an editor into the conversation before you start writing, or at minimum, before you're too deep into a first draft. An experienced editor can help you avoid structural problems early, which saves you significant time and money later.
