Choosing between IngramSpark and Amazon KDP is one of the biggest decisions you will make as an independent author. Each platform offers unique advantages, different distribution opportunities, and completely different marketing outcomes. Since both companies updated their policies and systems over the last two years, the comparison of IngramSpark vs Amazon KDP looks very different in 2025. As a result, understanding how they work together is essential for your long term publishing strategy.

Amazon KDP dominates the self publishing world. Millions of authors use it for both digital and print sales. In contrast, IngramSpark focuses on global distribution, bookstore reach, and library access. Because the two platforms serve different purposes, successful authors often use both. The key is knowing what each platform does best and how to build a strategy that supports your goals.

Understanding the Core Differences

KDP and IngramSpark look similar on the surface, but they serve different parts of the publishing ecosystem. KDP is designed for speed, convenience, and Amazon sales. IngramSpark is designed for wide distribution through bookstores, libraries, schools, and international retailers. Therefore, your goals will determine which platform you prioritize.

KDP gives you instant access to Amazon’s customer base. IngramSpark gives you global reach beyond Amazon. KDP offers high royalties for Kindle books and free print uploads. IngramSpark provides access to more retailers but charges setup fees unless you use promotional codes. Because of these differences, authors choose based on either convenience or long term distribution growth.

This chart shows how each platform supports different author goals.

Amazon KDP Strengths

Amazon KDP excels at digital publishing. Kindle ebooks account for a large percentage of indie author income, especially in romance, thriller, and fantasy genres. Because KDP is integrated with Amazon, you gain instant exposure, quick rankings, and access to tools such as Amazon Ads, KENP page reads, and A+ Content.

KDP’s print system is simple. You upload your files, approve your proof, and your paperback or hardcover becomes available to millions of Amazon shoppers. In addition, KDP prints on demand, so you never pay upfront costs. This convenience attracts most new authors.

Another strength is KDP’s ability to update books quickly. You can change prices, descriptions, keywords, and categories within minutes. This flexibility allows authors to test strategies and adjust their marketing without complications.

IngramSpark Strengths

IngramSpark offers unmatched distribution power. Bookstores, libraries, universities, and international retailers use Ingram’s system to order books. As a result, IngramSpark is the preferred platform for authors who want to reach physical stores or academic markets.

Print quality is another advantage. IngramSpark’s premium color and hardcover options often exceed KDP’s quality. Authors who produce photo books, cookbooks, or illustrated editions often prefer IngramSpark for this reason.

In addition, IngramSpark allows you to set bookstore friendly discounts and return policies. These features help bookstores feel confident ordering your book. Because of these benefits, traditionally published authors and hybrid authors rely heavily on IngramSpark for print distribution.

Graph: Which Platform Authors Choose Most Often in 2025

Author Preference Split

Amazon KDP Only................. █████████████ 60%
IngramSpark Only................ ████ 12%
Both Platforms Combined......... ██████████ 28%

Most indie authors use KDP alone, although a significant number use both platforms to maximize reach.

Pricing and Fees in 2025

KDP remains free to use. You pay nothing to upload your book or keep it published. In contrast, IngramSpark usually charges setup fees for print books unless you use a promotional code. Fortunately, IngramSpark releases several free upload codes throughout the year, which eliminates these costs.

Royalties differ as well. KDP offers up to 70 percent royalties for ebooks and competitive print royalties. IngramSpark’s print royalties are slightly lower because of retailer discounts, but the wider distribution often compensates for this difference.

Print Quality Differences

Print quality matters for authors who create visually rich books. KDP’s quality is strong for standard novels, workbooks, and low content books. However, IngramSpark often delivers sharper interior printing, better paper options, and more consistent color reproduction.

For fiction, the difference is minimal. For illustration heavy books, the difference can be significant.

Which Platform Is Best for Your Goals?

Your publishing goals determine your ideal platform. If speed, convenience, and Amazon sales matter most, choose KDP. If bookstore availability, library access, and global distribution matter more, choose IngramSpark.

Many authors begin on KDP to take advantage of Amazon’s ranking system. After their book is established, they add IngramSpark for expanded reach. This blended strategy gives authors the benefits of both platforms.

Should You Use Both Platforms?

Most successful indie authors eventually use both. KDP captures Amazon readers quickly, while IngramSpark expands your global footprint. Using both platforms gives you more opportunities to reach new readers, attract bookstore attention, and increase your book’s credibility.

In addition, using both platforms protects your income. If one platform changes its policies, you still have a second source of distribution and revenue.

Final Thoughts: Your Best Publishing Path in 2025

Amazon KDP and IngramSpark both offer powerful advantages for independent authors. KDP supports digital success, quick updates, and a strong presence in the Amazon ecosystem. In contrast, IngramSpark supports long term distribution, professional print quality, and bookstore access. The best choice depends on your goals, although many authors combine both platforms for maximum impact.
