How it works after you pay

  1. 1. Gumroad takes the payment and emails you a receipt with a licence key.
  2. 2. Come back and paste that key at /activate. You don't need an account first — the key is how we know it's you.
  3. 3. We set your account up and email you a link to choose a password.

Accounts are created by hand rather than instantly, so there may be a short wait between paying and getting in.

How a book comes together

Eight stages, each one a decision you make rather than a button you watch.

  1. Discover

    Understand demand and evidence for a niche.

  2. Choose

    Select the strongest book opportunity.

  3. Build

    Turn the opportunity into a concrete chapter plan.

  4. Produce

    Turn the approved plan into a manuscript.

  5. Review

    Confirm the manuscript is genuinely ready.

  6. Style

    Choose a professional look for your book.

  7. Cover

    Give the book a visual identity.

  8. Publish

    Package the book for release.

Every claim traceable

Research is gathered before a word is written, and each chapter is built from it. You can download a report showing which evidence was used, in which chapter, and where.

What you end up with

  • An ebook, validated against EPUBCheck
  • A paperback interior, typeset to your trim size
  • A full print cover — front, spine and back
