Direct ebook sales give you a storefront you can shape around your readers. They also make you responsible for discovery, delivery, support and the practical cost of acquiring a customer.
Check your publishing commitments
If the ebook is enrolled in KDP Select, Amazon requires digital exclusivity during the enrolment period. Do not offer the same digital book on Shopify until your agreement allows it. Ordinary KDP publishing and KDP Select are not the same programme.
Choose reader-friendly formats
PDF suits a fixed layout; EPUB is useful when readers need text to reflow. State the formats included and provide opening instructions. If you offer both, test both instead of assuming the export preserved every table or image.
Sell a clear edition
Show a sample chapter, table of contents and edition date. Explain whether future corrections or major updates are included. A premium bundle should add useful material such as exercises or audio, not only increase the file count.
Protect without obstructing reading
Use PDF stamping where appropriate and avoid covering text or diagrams. Give buyers enough download attempts for their devices. Protection can discourage sharing, but a purchase should still be easier to use than a copied file.
Your practical action plan
- Prepare the deliverable. Keep an original backup and publish a clear version. List the formats, compatibility and licence scope before the customer purchases.
- Connect and test in Shopify. Map the file, link or key to the right product and variant. Use the appropriate standard, custom or scheduled delivery mode. Check a controlled purchase on desktop and mobile.
- Choose capacity and monitor it. Use catalogue size and expected monthly transfer to choose a plan. Track actual usage and support questions after launch, especially before a promotion.
Before you publish
- The product page matches the actual files, access and timing.
- A sample or preview reflects the product customers receive.
- The purchase, email and mobile access route have been tested.
- Compatibility, licence terms and support contact are easy to find.
- Capacity and costs have been checked against the current plan.
