KDP vs. IngramSpark: Which One Should You Use?
Both platforms are useful but for different reasons. This guide gives you the practical pros, cons, and setups that work in the real world.
1. The One-Sentence Answer
Most successful indie authors use both.
- KDP: best for Amazon ebook + print sales.
- IngramSpark: best for bookstores, libraries, and non-Amazon channels.
Instead of “KDP or IngramSpark?”, ask: “How should I combine them for my goals?”
2. Strengths of KDP
KDP is your default starting point.
- No platform fees: you only pay printing costs out of royalties.
- Massive Amazon reach: the world’s biggest ebook and online print retailer.
- Fast updates: easy to tweak your files, description, and pricing.
- Good royalty structure: especially for ebooks in the 70% range.
3. Strengths of IngramSpark
IngramSpark shines where Amazon is weakest: bookstores and libraries.
- Wide print distribution: access to bookstores and libraries via Ingram’s catalog.
- More format options: hardcovers, special trim sizes, and more paper choices.
- Bookstore-friendly discounts: you control wholesale discounts and returns.
If you want serious bookstore presence, you almost always need an IngramSpark-type solution.
4. Key Differences That Affect Your Decision
Distribution
KDP: unbeatable on Amazon, weaker outside of it.
IngramSpark: built for non-Amazon retail and institutional buyers.
Costs & Fees
KDP: no title setup fee; you can experiment more freely.
IngramSpark: may charge title setup or revision fees, depending on current promotions.
Perception
Many bookstores prefer ordering through Ingram. Using your own ISBN and imprint on IngramSpark can look more “traditional” to them.
5. Recommended Setups by Scenario
Scenario A – Amazon-First Author
Use: KDP only (ebook + print).
- Focus on Amazon reviews, keywords, and ads.
- Add IngramSpark only if you later see a clear need for bookstores.
Scenario B – Speaker / Consultant / Non-Fiction Pro
Use: KDP + IngramSpark.
- KDP for Amazon visibility and easy ordering.
- IngramSpark for bookstores, bulk orders, and your own imprint.
Scenario C – Wide Ebook & Wide Print
Use: KDP + aggregator + IngramSpark.
- KDP for Amazon ebook + print.
- An aggregator for Apple, Kobo, Google Play, etc.
- IngramSpark for non-Amazon print distribution.
6. What About ISBNs?
This is where imprint decisions matter.
- KDP’s free ISBN lists Amazon as the publisher for print.
- Your own ISBN (bought from your agency) lists your imprint instead.
- IngramSpark expects your own ISBN if you’re using your own imprint.
If you plan a serious author business, buying a block of ISBNs is usually worth it.
7. Practical Recommendation
If you feel overwhelmed, start small.
- Publish ebook + paperback on KDP.
- Watch sales and reviews for 60–90 days.
- If you see traction or have clear bookstore opportunities add IngramSpark for print.
