What Authors Should Know Before Publishing on Amazon KDP
Amazon KDP — Kindle Direct Publishing — is one of the most widely used publishing platforms in the world. It's also one of the most widely misunderstood. Authors often approach it with either too much optimism or too much skepticism. The reality is more nuanced.
Here's what you should actually know before deciding whether KDP is the right path for your book.
What KDP Is
KDP is Amazon's self-publishing platform. It allows authors to upload a manuscript and cover, set a price, and have a book available for sale on Amazon — in both digital (Kindle) and print-on-demand (paperback and hardcover) formats.
It's free to use. Amazon takes a percentage of each sale as a royalty cut. The author keeps the rest.
What KDP Does Well
KDP has genuine strengths.
Accessibility. Anyone can publish on KDP. There are no gatekeepers, no submission requirements, and no upfront costs.
Speed. A book can be live on Amazon within 72 hours of upload.
Royalties. KDP offers relatively favorable royalty rates compared to traditional publishing — up to 70% on Kindle sales in eligible price ranges.
Control. Authors retain control over pricing, content, and the ability to make changes at any time.
Print on demand. KDP's print-on-demand service means physical books are printed as they're ordered, with no inventory required.
What KDP Doesn't Do
Understanding KDP's limitations is just as important as understanding its strengths.
KDP doesn't edit your book. Whatever you upload is what gets published. If the manuscript has errors, inconsistencies, or structural problems, those will be in the published book.
KDP doesn't design your cover. You can upload any image as a cover. A poorly designed cover will hurt your book's credibility and sales.
KDP doesn't format your interior. Formatting matters more than most authors realize. A poorly formatted interior — inconsistent fonts, bad spacing, awkward page breaks — signals to readers that the book wasn't taken seriously.
KDP doesn't provide an imprint. Books published through KDP are self-published. That's not inherently a problem, but it's worth understanding. The book will not carry a publisher's name unless you've established your own imprint.
KDP doesn't guarantee discoverability. Being listed on Amazon doesn't mean readers will find your book. Amazon's catalog contains millions of titles. Discoverability requires marketing, reviews, and other factors that KDP doesn't provide.
KDP's ISBN situation is complicated. KDP offers free ISBNs, but those ISBNs are owned by Amazon and can only be used on Amazon. If you want to distribute your book through other channels, you'll need your own ISBN. (More on ISBNs in our separate article on the subject.)
KDP and Expanded Distribution
KDP offers an "Expanded Distribution" option that theoretically makes your book available through other retailers and libraries. In practice, this distribution is limited and inconsistent. Many booksellers and libraries are reluctant to stock KDP-distributed titles, and the royalty rates through expanded distribution are significantly lower.
If broad distribution matters to you, KDP alone may not be sufficient.
The Production Question
The most important thing to understand about KDP is that it's a distribution platform, not a publishing service. It will distribute whatever you give it. The quality of the final book — the editing, the cover, the formatting — is entirely the author's responsibility.
Authors who publish on KDP without professional editing, cover design, and formatting often end up with books that look and read like what they are: manuscripts that were uploaded without professional production.
That's not a criticism of KDP. It's a description of what the platform is and isn't.
When KDP Makes Sense
KDP is a good fit for authors who:
- Have already invested in professional editing, cover design, and formatting - Are comfortable managing the production process themselves - Are primarily targeting Amazon's audience - Don't need or want an imprint - Want maximum control and are willing to do the work that comes with it
When Working With a Publisher Makes More Sense
Working with a publisher makes more sense for authors who:
- Want professional production support included in the publishing process - Want their book published under a real imprint - Want broader distribution support - Prefer a structured process with editorial oversight
Making Sense Press offers publishing packages designed for authors who want more than a KDP upload. We're selective — we don't accept every submission — but for authors whose books meet our standards, we offer a professional publishing path with transparent pricing and real support.
