Ask which services are included: manuscript development, editing, cover design, formatting, platform setup or book marketing. Request a written scope, schedule and clear explanation of costs. Understand whether the provider offers consultation, production work or distribution access, as these are different responsibilities.
Confirm that you retain the rights and files stated in your agreement and know how approvals will work. A trustworthy publishing partner welcomes questions and avoids guarantees it cannot control. Clear expectations help authors choose support that fits their goals.
