A professional KDP publishing service should help prepare compliant files, organise metadata, explain ISBN and pricing choices, support uploads and quality checks, and leave the author clear about account access and ownership. It should not promise Amazon approval, bestseller status or guaranteed sales.
Production before upload
The manuscript, cover and interior files should be checked for the selected ebook or print format before anything is uploaded to KDP.
Account ownership matters
Authors should understand who controls the KDP account, tax and payment information, book metadata and future updates. Where possible, keep long-term platform access under the author or rights holder.
Pricing and royalties change
KDP royalty rules, list-price bands and printing costs can change, so the final settings should be checked against Amazon’s current help pages at publication time.
Official sources
Platform fees and rules can change. Use the source links below when making a final publishing decision.
