KDP vs IngramSpark
One of the most common questions new indie authors ask is whether they should publish their print books through Amazon KDP or through IngramSpark.
The honest answer is that they serve slightly different purposes. Many independent authors eventually end up using both platforms together, each handling the parts of publishing they do best.
The short answer
If your primary goal is selling books on Amazon, KDP is usually the easiest and most straightforward route.
If you want your book available through bookshops, libraries and the wider book trade, IngramSpark provides access to the global distribution network used by retailers.
For many authors the practical solution is to combine the two.
Side-by-side comparison
| Feature | KDP | IngramSpark |
|---|---|---|
| Primary purpose | Amazon publishing platform | Global book distribution network |
| Ebooks | Excellent Kindle support | Not its main focus |
| Paperbacks | Simple print-on-demand | Professional trade distribution |
| Hardbacks | Available in some cases | Strong support for hardback formats |
| Distribution | Primarily Amazon | Bookshops, libraries, retailers worldwide |
| Setup complexity | Very straightforward | More detailed setup |
| Wholesale discount | Not required | Required for trade distribution |
| Returns system | No traditional return system | Retail returns possible |
| Best for | Amazon-focused publishing | Trade distribution and hardbacks |
When KDP makes the most sense
For many indie authors, KDP is the simplest way to get started.
- you want fast publishing
- Amazon is your main sales channel
- you want simple setup
- you want Kindle ebook support
- you prefer minimal distribution complexity
It removes a lot of friction from the publishing process and allows authors to focus on writing, presentation and marketing.
When IngramSpark makes sense
IngramSpark becomes valuable when authors want access to the wider book trade.
- bookshop availability
- library distribution
- global retail catalogues
- hardback editions
- wider publishing infrastructure
It is particularly useful for authors building a catalogue or publishing imprint rather than simply uploading a single book.
Using both platforms together
A common strategy among indie authors is to combine both services.
Typical setups look something like this:
- KDP for Kindle ebooks
- KDP for Amazon print visibility
- IngramSpark for wider distribution
- IngramSpark for hardback editions
Each platform then handles the parts it is best at rather than forcing one system to do everything.
The bookshop myth
Many authors assume that once a book is listed in the Ingram distribution network, bookshops will automatically stock it.
Unfortunately that is not how it works.
Bookshops stock books they believe will sell. Being available through Ingram simply means the book can be ordered through their normal supply chain. It does not guarantee shelf space.
Distribution creates opportunity. It does not create demand.
The financial reality
Both platforms involve economic trade-offs.
- KDP print margins are often modest
- IngramSpark requires wholesale discounts
- print cost increases with book length
- returns policies can introduce risk
Understanding the numbers is an important part of publishing decisions.
My view as an indie author
KDP and IngramSpark are not really competing services. They are different tools within the same publishing toolbox.
KDP is excellent for fast publishing and Amazon visibility.
IngramSpark is valuable for broader distribution and professional publishing infrastructure.
Using both together often provides the most flexibility for indie authors building a long-term catalogue.
Quick takeaway
KDP is ideal for Amazon publishing. IngramSpark extends your reach into the wider book trade. Many authors use both.
