You have finished your manuscript. The editing is done, the cover looks professional, and you are finally ready to publish. Then comes the question that stops many authors in their tracks: where should you actually publish this book? Amazon KDP dominates conversations in author groups, but IngramSpark keeps appearing as the “serious author” choice. The decision feels overwhelming because each platform leads down different paths with different opportunities and limitations.
This is not a trivial choice. Your publishing platform determines where readers can find your book, how much money you earn per sale, what formats you can offer, and how much control you maintain over pricing and distribution. Getting it right from the start saves headaches later. Getting it wrong can mean republishing, dealing with duplicate listings, or missing sales opportunities.
The good news? Both platforms are legitimate, valuable options that serve different author needs brilliantly. The key is understanding which aligns with your goals, technical comfort level, and publishing strategy. Let’s break down exactly what each platform offers so you can make the choice that serves your book best.
The Quick Answer for Authors in a Hurry
If you want the simplest path to publishing with the largest potential audience, especially for ebooks, Amazon KDP is your platform. If you want wide print distribution including bookstores and libraries, are willing to invest more time and money upfront, and want your book available through multiple retailers, IngramSpark deserves serious consideration. Many successful authors eventually use both platforms strategically.
Understanding Amazon KDP: The Dominant Force
Amazon KDP (Kindle Direct Publishing) has transformed self publishing by making it remarkably easy for anyone to publish both ebooks and print books with zero upfront costs. You upload your manuscript and cover files, fill in metadata, set your price, and within 72 hours your book is live and available to millions of Amazon shoppers worldwide.
The platform’s dominance is staggering. Amazon controls roughly 67% of all book sales in the United States and even larger percentages in some other markets. For ebooks specifically, Amazon’s market share climbs even higher. This means publishing on KDP puts your book in front of more potential readers than any other single platform.
Ebook Publishing on KDP
KDP makes ebook publishing almost effortless. Upload your manuscript as a Word document or ePub file, preview how it looks on different devices using their previewer tool, and publish. The platform automatically converts your file to Kindle format and makes it available across all Kindle apps and devices.
Royalty options are straightforward. Choose 35% royalties if you want to price your ebook under $2.99 or above $9.99, or opt into the 70% royalty option for books priced between $2.99 and $9.99. The 70% option requires enrolling in KDP Select, which makes your ebook exclusive to Amazon for 90 day renewable periods. In exchange for exclusivity, you gain access to Kindle Unlimited, where subscribers can read your book for free while you earn payment based on pages read.
Many authors find KDP Select worth the exclusivity trade off, especially when starting out. Kindle Unlimited subscribers are voracious readers who discover new authors regularly. The page reads can generate significant income, sometimes exceeding direct sale royalties. However, exclusivity means your ebook cannot be sold anywhere else, not on Apple Books, not on Kobo, not on your own website.
Print on Demand with KDP
KDP also offers print on demand services at no upfront cost. Upload your print ready PDF files, choose trim size and paper options, and set your price. When someone orders your book, Amazon prints and ships it directly. You never touch inventory, handle shipping, or risk money on print runs that might not sell.
Print royalties are lower than ebook royalties because printing costs come out of each sale. Your royalty equals 60% of list price minus printing costs, which vary based on page count, trim size, and whether you choose black and white or color interior. A 300 page trade paperback might cost around $4 to print, so a book priced at $14.99 yields roughly $5 in royalties after printing costs are deducted.
The limitation with KDP print is distribution. Your book appears on Amazon properties (Amazon.com, Amazon.uk, etc.) but is not available through other retailers, bookstores, or libraries. For many authors, especially those writing in genres where readers shop primarily on Amazon, this limitation barely matters. Romance, thriller, and fantasy readers overwhelmingly buy from Amazon. However, certain nonfiction categories and literary fiction perform better with wider distribution.
What KDP Does Brilliantly
Speed and simplicity are KDP’s superpowers. You can go from finished manuscript to published book in days with zero financial investment. Changes and updates happen quickly. Spot a typo after publishing? Upload a corrected file and it goes live within 72 hours. Want to experiment with pricing? Adjust it anytime and see results immediately.
The platform is remarkably forgiving for beginners. The upload process is intuitive, error messages are clear, and there are countless YouTube tutorials walking through every step. If you can create a Word document, you can publish on KDP.
Marketing tools like Kindle Countdown Deals and Free Book Promotions provide promotional options exclusive to KDP Select authors. Running limited time sales or offering your book free for a few days can boost visibility and attract reviews that help long term discoverability.
Where KDP Falls Short
The biggest limitation is distribution scope. Your print books only sell through Amazon. Readers who prefer shopping at Barnes & Noble, independent bookstores, or through other online retailers cannot access your book. Libraries using services like OverDrive cannot order your book for their collections. This matters more for some genres and author goals than others.
Print quality is functional but not exceptional. KDP uses standard quality paper and binding suitable for most books but not ideal for high end photography books, cookbooks with lots of images, or books where print quality significantly impacts reader experience.
Expanded distribution, an option KDP offers to make print books available through some other retailers, comes with significant royalty cuts and limited actual distribution. Most authors find the trade off not worth it, especially when IngramSpark offers genuinely wide distribution.
Understanding IngramSpark: The Professional Distribution Choice
IngramSpark operates differently from KDP in almost every way. It is a professional level service targeting authors who want the same distribution channels available to traditional publishers. Your book goes into Ingram’s catalog, the largest book wholesaler and distributor in the world, making it available for order by bookstores, libraries, online retailers, and specialty shops.
The Setup Investment
IngramSpark charges upfront fees that can surprise authors accustomed to KDP’s free model. Each format you publish (ebook, paperback, hardcover) costs $49 to set up. Uploading a new edition or making changes to already published files costs $25 per file. These fees add up quickly if you make mistakes or need to update covers and interior files after publishing.
However, IngramSpark regularly runs promotions offering free setup or revision uploads. Many experienced authors time their IngramSpark publishing around these promotions to minimize costs. Signing up for their email list ensures you know when promotions are running.
The fees serve a purpose beyond generating revenue for Ingram. They encourage authors to upload polished, professionally prepared files rather than treating the platform as a testing ground. This quality gate means books in Ingram’s catalog generally meet professional standards, which retailers and libraries appreciate.
Print Distribution That Actually Reaches Bookstores
The primary reason authors choose IngramSpark is legitimate bookstore and library distribution. When your book is in Ingram’s catalog with returnability enabled and appropriate trade discounts set, bookstores can order it just like traditionally published books. Libraries can order through their standard channels. Online retailers beyond Amazon can stock it.
This does not mean bookstores automatically stock your book. Physical shelf space is limited and competitive. But it means they can order your book when customers request it, when it fits their inventory needs, or when your marketing efforts drive demand. You have access to the same channels traditionally published authors use.
The returnability option is crucial for bookstore distribution but comes with risk. Enabling returns means bookstores can return unsold copies for credit. This reduces their risk, making them more willing to stock unknown authors. However, returned books mean you must pay back the royalty you earned on the initial sale. For authors doing events, local bookstore placement, or active outreach to indies, returnability opens doors. For authors focused primarily on online sales, the risk may outweigh benefits.
Understanding Discounts and Royalties
IngramSpark royalties are more complex than KDP’s straightforward percentages. You set a list price, choose a discount (typically 55% for bookstore distribution or 30-40% for online only), and receive what remains after discount and printing costs are deducted.
A $14.99 book with a 55% discount means retailers can purchase it for $6.75. If printing costs $4, your royalty is $2.75 per book. The same book with a 40% discount yields higher royalties ($5 after a $4 printing cost) but may be less appealing to bookstores who expect industry standard 55% discounts.
Print costs on IngramSpark are competitive with KDP and sometimes slightly lower, especially for larger page counts. The real difference is how discounts impact your per book earnings compared to KDP’s simple formula.
Ebook Distribution Beyond Amazon
IngramSpark distributes ebooks to Apple Books, Barnes & Noble, Kobo, and other retailers globally. If you want your ebook available everywhere without enrolling in KDP Select exclusivity, IngramSpark (or alternative aggregators like Draft2Digital or PublishDrive) provides that access.
Ebook royalties through IngramSpark are less generous than KDP. You typically earn about 40% of list price after Ingram’s fees and retailer cuts, compared to 70% on KDP. However, reaching readers who shop exclusively on Apple or Kobo can make the lower royalty worthwhile. Some genres perform surprisingly well on non Amazon platforms.
What IngramSpark Does Brilliantly
Professional legitimacy is IngramSpark’s core strength. Your book sits in the same catalog as books from Penguin Random House and Simon & Schuster. Librarians and bookstore buyers can order through their established systems. Media outlets and industry professionals see IngramSpark published books as more legitimate than Amazon only titles.
Global distribution is genuinely global. IngramSpark has printing facilities worldwide, meaning your book can be printed on demand in the UK, Australia, and other markets without international shipping costs or delays. This makes international sales more profitable and accessible.
Hardcover options are available at reasonable costs, something KDP only recently began offering with limitations. For nonfiction authors, business book authors, or anyone wanting a premium format, IngramSpark hardcovers provide quality options.
Where IngramSpark Falls Short
Complexity deters many beginning authors. The setup process requires more technical knowledge than KDP. File requirements are stricter. Error messages are less helpful. The dashboard is functional but not intuitive. Authors comfortable with technology adapt quickly, but less technical authors find the learning curve frustrating.
Upfront costs create barriers when you are publishing your first book on a tight budget. Paying $49 to $98 to publish paperback and ebook formats, plus potentially needing to pay for file corrections, adds financial pressure when you are uncertain if the book will earn back the investment.
Sales reporting and payments are less frequent and less transparent than KDP. IngramSpark pays quarterly and reports sales with more delay than Amazon’s near real time data. For authors who check sales obsessively or rely on steady cash flow, this creates frustration.
Strategic Combinations: Using Both Platforms
Many experienced self published authors publish on both platforms strategically. The most common approach is publishing ebooks exclusively on KDP to access Kindle Unlimited while using IngramSpark for print to gain wide distribution. This combination provides access to KU readers while ensuring print books reach bookstores and libraries.
This dual platform strategy requires careful execution to avoid duplicate listings that confuse customers. On IngramSpark, you publish print only by not uploading an ebook file. On KDP, you enroll the ebook in KDP Select for exclusivity while keeping print out of expanded distribution to avoid conflicts with IngramSpark print distribution.
Another approach uses KDP for everything initially, then adds IngramSpark later if bookstore distribution becomes strategically important. This lets you test the market, build readership, and establish sales before investing in IngramSpark setup. Once you have proven demand, adding IngramSpark expands reach without risking money on unproven books.

This approach works well for authors with established audiences across platforms or writing in genres where readers shop beyond Amazon.
Making Your Decision: Which Platform Fits Your Goals?
Choose Amazon KDP if you are publishing your first book, working with a limited budget, want the simplest process possible, write in genres where Amazon dominates reader shopping, or plan to leverage Kindle Unlimited for visibility and income. KDP gives you the fastest path to published author status with the largest immediate audience.
Choose IngramSpark if you want bookstore and library distribution, are comfortable with more complex technical requirements, can invest setup fees, write nonfiction or literary fiction that performs well in bookstores, or plan to do local events and book signings where bookstore placement matters. IngramSpark positions your book as a professional product with wide availability.
Consider using both platforms if you want the best of both worlds, are willing to manage slightly more complexity, and have books that benefit from both Kindle Unlimited access and wide print distribution. The combination strategy works brilliantly for many authors once they understand how to execute it without creating conflicts.
Beyond Platform Choice: What Actually Matters More
Here is what authors obsessing over platform choice sometimes miss: the platform matters far less than the book’s quality and your marketing efforts. A brilliant book with effective marketing succeeds on either platform. A poorly executed book with no marketing fails everywhere.
Focus first on ensuring your manuscript is professionally edited, your cover looks competitive with traditionally published books in your genre, and your book description compels browsers to buy. These factors impact success far more than distribution platform.
Then develop realistic marketing strategies appropriate for your goals and resources. Email list building, social media presence, reader magnets, collaboration with other authors, and consistent visibility efforts determine whether your book finds readers regardless of where it is published.
The platform provides the infrastructure. You provide everything else that makes publishing successful. Choose the platform that aligns with your goals and technical comfort level, then invest your energy in the work that actually moves books: creating excellent content and connecting it with readers who will love it.
Your Publishing Journey Starts With One Decision
IngramSpark and Amazon KDP both offer legitimate paths to publishing success. Neither is universally better. Both serve different author needs brilliantly. Your job is understanding which serves your specific situation, then executing professionally on whichever platform you choose.
At Bright Era Publishing, we help authors turn their content into professionally published self-published books that reach readers.
