how to sell a book to amazon can be done through Amazon’s Kindle Direct Publishing (KDP) platform for digital versions, or as a physical book via FBA or FBM. Self-publishing through KDP allows you to upload a manuscript, design a cover, and earn royalties. For physical books, you can list them under the appropriate category and choose to fulfill orders yourself or let Amazon handle it. Reviews, categorization, and promotional pricing help increase visibility and sales across formats.
