Amazon KDP
Kindle Direct Publishing — the dominant self-publishing storefront for ebooks and print-on-demand. Optional KDP Select exclusivity unlocks Kindle Unlimited. Essential for most indies; not the only store if you go wide.
IngramSpark
What it is
Print (and ebook) distribution via Ingram’s trade network — the channel bookshops and libraries often use to order. Higher bar for files and metadata than KDP; valuable when you want bookstore-friendly wide print.
Pricing model
Paid — Title setup/revision fees may apply; wholesale print distribution. Always confirm on the vendor site before buying; plans change.
