Comparison

KDP vs IngramSpark

KDP and IngramSpark are the two main self-publishing routes, and they serve different goals. KDP is Amazon's in-house platform — fastest, free to use, and unbeatable on Amazon itself. IngramSpark is the route into the global book trade: bookstores, libraries, and international wholesalers. Most serious indie authors end up using both.

Example scenarios

Realistic situations and which platform tends to fit best.

Who should choose KDP?

Authors whose readers buy on Amazon — which is the vast majority of indie buyers in fiction, non-fiction, and low-content books. Free, fast, with the best royalties on Amazon and access to Kindle Unlimited.

Who should choose IngramSpark?

Authors targeting bookstores, libraries, schools, or international retailers; or anyone publishing premium hardcovers. IngramSpark gives you a real catalog presence outside Amazon — at the cost of higher print costs and a steeper learning curve.

When should you use both?

Most serious authors do. Use KDP for the Amazon paperback and Kindle edition (best royalties there), and IngramSpark for hardcover and non-Amazon distribution. Set KDP's Expanded Distribution off for those formats so the two don't conflict.

Common publishing mistakes

Pricing the IngramSpark edition higher than KDP and confusing buyers; turning on KDP Expanded Distribution while also distributing through IngramSpark; underestimating IngramSpark's print costs and ending up with a negative wholesale margin.

Frequently asked questions

Is IngramSpark better than KDP?
Neither is universally better. KDP wins on Amazon; IngramSpark wins on bookstore and library distribution. Most authors use both for the formats each does best.
Can I publish on both platforms?
Yes — that's the standard pro setup. Use KDP for the Amazon edition, IngramSpark for everywhere else, and turn KDP's Expanded Distribution off to avoid conflicts.
Which pays higher royalties?
KDP usually pays more per Amazon sale because the print cost is lower and the royalty rate is 60% of list. IngramSpark pays more on non-Amazon sales where KDP barely reaches.
Which is easier for beginners?
KDP — the tooling is simpler, files are more forgiving, and there are no revision fees while you learn. IngramSpark is worth adding once your title is selling and bookstore reach matters.
Do I need an ISBN for both?
KDP gives you a free Amazon-only ISBN. IngramSpark requires your own ISBN. If you plan to use both, buy your own ISBN so the same book has one identity across all retailers.
