Authors should ask several important questions before choosing a ghostwriting agency for their book project. They should inquire about the agency's experience, portfolio, writing process, and expertise in their specific genre. It is also important to understand how research, interviews, outlining, writing, editing, and revisions will be handled. Authors should ask about pricing, payment schedules, project timelines, deliverables, and included services. Questions about confidentiality, manuscript ownership, copyright, and rights should also be discussed. Authors can also ask how communication and feedback will be managed throughout the project. Getting clear answers in advance can help set realistic expectations and create a smoother working relationship.
