What is a book publishing service?
In this Big Impact Books guide, a book publishing service is any provider that takes over some or all of the work of turning an author's ideas into a published book: manuscript development, editing, design, production, distribution and promotion.
Services differ mainly in how much of that list they cover. Some handle a single task, such as cover design. Others, like Big Impact Books, run the whole journey from guided interviews to podcast placements and media coverage. Knowing which tasks you want to own is the fastest way to narrow the field.
