Hybrid publishing contracts vary widely depending on the publishing house and the author. In general, hybrid publishers charge some kind of fee for the publishing services they provide (typically between $100–$2,000), which may include, but is not limited to, cover design, editing, and formatting. Hybrid publishers may also require authors to purchase a certain amount of copies of the book or to provide some kind of payment up front in return for the publication. Additionally, the publisher may require a percentage of the book’s sales going forward.
It’s important to clarify the specific terms with your prospective hybrid publisher before signing a publishing contract. You should be aware of all the services they will provide, how much they will charge, how much control you will have in the production process, and how much they will be taking in terms of royalties.
Ultimately, it’s important to understand the terms of the contract and to do your research. Check out reviews of a publisher before signing anything, make sure that you are getting value for your money, and it is a safe and secure decision for you and your work.
