IngramSpark vs Amazon KDP for Self-Publishers: Distribution Differences That Matter
Self-publishing authors today face a pivotal distribution choice: should you use Amazon KDP, IngramSpark, or both to ensure your book reaches its intended audience and provides maximum earning potential? These platforms differ substantially in how your book is listed, who can order it, the reach you achieve, and how much you ultimately earn from sales. At Page Publishing, our mission is to untangle this complexity and offer guidance that is both actionable and backed by our team’s industry expertise. Here, we break down what truly matters for your distribution decision.
Understanding KDP and IngramSpark: Key Definitions for Self-Publishers
Amazon KDP (Kindle Direct Publishing) allows authors to upload and sell print-on-demand books, making them available to Amazon customers globally. Distribution is highly effective if your audience relies mostly on Amazon for books. IngramSpark acts as a publishing aggregator, distributing your book to tens of thousands of independent bookstores, libraries, and major retail chains across the U.S. and internationally.
Distribution: Who Actually Gets to Order Your Book?
The most significant difference between these platforms is how widely your book is available and which buyers are willing to stock it. With KDP, your book is published and listed on Amazon, a retailer that many bookstores view as a competitor. With IngramSpark, your title is listed in the Ingram Content Group’s catalog, opening doors to brick-and-mortar retailers, independent bookstores, libraries, and universities worldwide.
Amazon KDP Distribution
- Excellent for targeting the vast Amazon customer base in any territory where Amazon operates.
- Books enrolled in KDP Expanded Distribution are technically available to other retailers, but on less favorable terms for bookstores and for you as the author.
IngramSpark Distribution
- Access to over 45,000 outlets including independent bookstores, Barnes & Noble, libraries, and specialty retailers.
- Provides international reach not limited to Amazon customers.
- Bookstores are more likely to order when the book is available through their existing wholesale distributors (via IngramSpark) rather than through Amazon.
Royalties and Wholesale Discounts: Who Gets Paid and How Much?
Royalties and discounts might seem arcane, but they directly affect your bottom line. Amazon KDP pays straightforward royalties for Amazon sales, but drops your royalty rate if your book sells through expanded distribution. In contrast, IngramSpark lets you set a wholesale discount rate—if you set the common 55% discount, retailers are most likely to order your book for store shelves. Lower discounts result in fewer (or no) retail orders, which is why understanding discount structures is essential for wider distribution.
IngramSpark in Practice
- Lets you control discount rates (commonly 40-55%).
- At a 55% discount, bookstores are more willing to stock your book.
- This flexibility comes with the responsibility to price strategically for both reach and royalties.
KDP’s Approach
- Lower print cost per copy compared to IngramSpark.
- Higher royalty for Amazon sales, but much lower royalty for books sold through expanded distribution.
Print Options, Costs, and Fees: What Every Author Should Know
The fine details of print quality, file revisions, and associated fees often surprise first-time self-publishers. KDP offers free file revisions and a lower per-copy print cost, making it an attractive choice for simple, ongoing updates and high-volume Amazon sales. IngramSpark provides hardcover options, a broader range of sizes, and high-quality color printing, but may cost $1-$2 more per copy and charges revision fees after your first 60 days.
- KDP: Free revisions at any time, but less flexibility in trim size and finish.
- IngramSpark: Hardcover options, more trim choices, fees for revisions after the initial period.
Step-By-Step: How Authors Successfully Use Both Platforms
Many experienced authors maximize visibility and earnings by leveraging both KDP and IngramSpark. The main requirement is having your own ISBN (not the free ones offered by either platform) and not enrolling in KDP’s expanded distribution. Here’s how this dual strategy works in practice:
- Purchase and assign your own ISBN to your book.
- Upload the title to KDP for direct Amazon distribution and take advantage of their higher royalties and free updates.
- Upload separately to IngramSpark, entering the same ISBN and tailoring your wholesale discount for optimal bookstore appeal.
- Let Amazon fulfill its own sales, while IngramSpark makes your book available to the rest of the retail market and libraries.
This approach can require extra management and technical attention, especially around file specifications and pricing consistency. At Page Publishing, we often assist authors in setting up and coordinating these dual listings to ensure a seamless experience and broadest possible reach.

Best Practices for Self-Published Authors Navigating Distribution Choices
- Clarify your primary audience: are your readers shopping on Amazon, in bookstores, or via libraries?
- If you anticipate most sales through Amazon, KDP may be enough. If you want physical bookstore presence, IngramSpark or dual publishing is recommended.
- Secure your own ISBN for ultimate control across all channels.
- Price your book strategically, accommodating wholesale discounts if targeting retail outlets.
- Prepare for the technical requirements of each platform—consider professional support if needed.

KDP is primarily a gateway to Amazon shoppers, while IngramSpark provides wide distribution to independent bookstores, libraries, and other retail channels across the globe.
Which platform offers higher royalties?
KDP typically gives higher royalties on Amazon sales. IngramSpark lets you tailor retailer discounts for expanded reach but often means lower royalties per book due to higher wholesale discounts and printing costs.

Very rarely. Bookstores tend to avoid Amazon as a supplier and prefer ordering from established distribution networks like Ingram (via IngramSpark).
