Amazon KDP book creation and publishing

We create and publish books on Amazon Kindle Direct Publishing (KDP): puzzle and activity books, coloring books, children's picture books, journals and ebooks. We handle niche research, interiors, covers, metadata, keywords and the upload, under your own KDP account so the royalties are yours.

  • Niche and keyword research
  • Interior layout; puzzles generated and checked by software

  • Paperback, hardcover and Kindle formats
  • Title, description, keywords and categories

Note: Amazon asks publishers to declare AI-generated content. We tell you exactly what was made with AI so your declarations are accurate.

Same process for every project, sized to yours.

Brief

You tell us the goal, the users and the deadline. We ask the questions that change the price.

Fixed quote

A written scope, timeline and price. Larger projects are split into milestones.

Design

Wireframes and a clickable prototype, so you approve how it works before we code it.

Build

Weekly demos of working software on your phone or browser. You can change course early.

Launch & care

We publish, hand over code and logins, and stay on for fixes and updates.

Questions

KDP publishing: common questions.

Whose KDP account is used?

Yours. The books, sales and royalties stay on your account. We work from files and access you provide.

Are the puzzles correct?

Yes. Our software generates every puzzle and checks it has a valid solution, and the answer keys are printed from the same data.

Do you write story books too?

Yes, children's picture books and series. We plan the characters, text and illustrations with you.

Do you guarantee sales?

No. Amazon decides placement and readers decide what to buy. We give each book the best research, design and listing we can.
