How does KDP Publishing work?

KDP Publishing is a platform for authors to self-publish eBooks and paperback books.
For eBooks, authors can directly upload their book files, and it will appear in the Kindle store as an eBook for readers to purchase and instantly download.
For printed books, authors upload their book files and KDP Publishing uses print-on-demand technology to print the paperback book once it’s purchased; the printing costs will be subtracted from the royalties you earn from every book sold.

Here’s how KDP Publishing works:

#1 – Upload your book files to Amazon KDP.
#2 – Publish your book to the KDP platform.
#3 – Readers can purchase your eBook and instantly download it to their device.
#4 – Readers can purchase your paperback copy and Amazon’s KDP platform will use print-on-demand technology to print and ship your book directly to the reader once purchased.
#5 – Amazon will pay you book royalties per book sold on the KDP platform.
