The short version

  • Only Kindle Direct Publishing has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kindle Direct Publishing the 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.; Shopify using any payment provider other than Shopify Payments adds a transaction fee on top of the card rate, at 2% on Basic falling to 0.2% on Plus
  • They diverge on capability: Kindle Direct Publishing covers Free publishing, Shopify covers Hosted ecommerce platform.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kindle Direct Publishing

  • The 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.
  • The delivery fee, roughly $0.15 per megabyte, is deducted on every sale under the 70% tier, so image-heavy or long ebooks lose meaningfully more revenue per sale than a plain-text book at the same list price.
  • KDP Select exclusivity, while optional, is the only route to Kindle Unlimited page-read royalties, so authors face a real trade-off between Amazon-only reach with page-read income and wider distribution without it.
  • Public domain or primarily public-domain content is capped at the 35% royalty regardless of price, so that category of publisher cannot access the higher rate at all.
  • As a single-retailer platform, an author relying solely on KDP is concentrated in one sales channel controlled entirely by Amazon policy, which has changed royalty terms before (the July 2026 price band expansion is itself an example) and can do so again.

Shopify

  • Using any payment provider other than Shopify Payments adds a transaction fee on top of the card rate, at 2% on Basic falling to 0.2% on Plus
  • That fee makes the cheapest plan the most expensive place to use an outside processor, which is the opposite of how plans usually work
  • Card rates also improve with the plan, from 2.9% on Basic to 2.7% on Advanced
  • Amex is charged at a higher rate than other cards on every plan below Plus
  • Plus starts at $2,300 a month
  • The advertised lower monthly prices require paying a year up front
