Amazon KDP vs IngramSpark: Which Publishing Platform Is Best?

Amazon KDP and IngramSpark are the two most important self-publishing platforms on the planet. Most first-time authors ask the same question: which one should I use? The honest answer for serious authors is usually both — but the way you use them matters.

Amazon KDP: Reach and Simplicity

KDP is Amazon's in-house publishing platform. It's free, easy to use, and gives your book instant access to the largest reader base in the world. Royalties are strong (up to 70% on Kindle) and you can enroll in KDP Select for extra promotional tools like Kindle Unlimited.

IngramSpark: Bookstore and Library Distribution

IngramSpark is a distribution powerhouse. It connects your book to more than 40,000 bookstores, libraries, and retailers globally — including Barnes & Noble, Books-A-Million, independent bookstores, and international chains that Amazon simply doesn't reach the same way.

Feature-by-Feature Comparison

• Reader base: KDP wins on Amazon itself; IngramSpark wins everywhere else.
• Royalties: KDP is higher on Kindle; IngramSpark is competitive on print.
• Print quality: Both excellent; IngramSpark has more premium finishes.
• Setup: KDP is easier; IngramSpark has more control and options.
• Returns: IngramSpark supports returnable copies for bookstore orders.

So Which Should You Choose?

For most authors we work with, the answer is both. Use KDP for Amazon (Kindle and paperback) and IngramSpark for everything else — Barnes & Noble, libraries, independent bookstores, and international retailers. This dual setup maximizes reach without cannibalizing sales.
