The best time to hire a publishing service provider is early in the book development process, especially when you are planning how to write a children’s book. Many authors focus solely on writing and underestimate editing, formatting, illustration, and distribution challenges. A professional provider can guide you from manuscript refinement to market-ready design, ensuring your story appeals to young readers. Early collaboration also helps manage timelines, reduce costly revisions, and navigate publishing platforms efficiently, giving your children’s book the best chance to succeed in a competitive market.
