The Partial Manuscript Deal: A New Paradigm for Authors?

Updated Oct 2026: this editorial has been rewritten and now cites its sources.

Can an author sell a book before finishing it? For some categories the answer has long been yes, and for others it is usually no. The difference matters because it shapes how authors spend their time, how much risk they carry and when they get paid. This editorial explains how partial-manuscript and proposal deals work, where they apply, and what current data on author income suggests about the stakes.

Nonfiction: the proposal model

For most adult nonfiction, the standard route to a traditional deal is a book proposal rather than a finished manuscript. Jane Friedman, a longtime publishing industry writer, explains in her guide that nonfiction authors can typically sell a book on the strength of a proposal and sample chapters, with the publisher then paying the author to complete it.

A proposal is a business document. It describes the book, its audience, the competition and the author's platform, and it includes a chapter outline and sample material. What the publisher buys is a plan, along with the author's ability to carry it out. Friedman notes that most proposals run about 10 to 25 double-spaced pages, not including sample chapters, that complex projects can reach 50 pages or more once sample chapters are included, and that a properly developed proposal can take weeks or longer to prepare. Put another way, a partial manuscript is not a shortcut around the work. It moves a large share of that work to the start, before any money changes hands.

Fiction and memoir: usually finished first

Fiction works differently. Friedman's guidance is that most first-time novelists must finish their manuscript before approaching agents or editors. Memoir sits between the two. Friedman notes that it can be very challenging for unpublished memoirists to sell on a proposal, and that writing the book first can help show that an unknown writer can carry the project.

The "partial manuscript deal" is, then, nothing new. For nonfiction it is the norm. For fiction it is the exception.

Why the model matters for income

The timing of a deal matters because most authors earn modest sums from their books. The Authors Guild's 2023 survey of 5,699 published authors, both traditionally and self-published, found that the median book income for full-time authors was $10,000 in 2022, counting advances, royalties and fees from licensing and subsidiary rights, and the median for all respondents, including part-time writers, was $2,000. The Guild noted that 80 percent of respondents considered themselves professional authors, but only 35 percent considered themselves full time. Full-time authors' median income from books and other author-related work combined was $20,000, and the Guild concluded that half of full-time authors earn below minimum wage in many states from all their writing-related work.

Genre makes a large difference. The same survey found a median book income of $31,725 for full-time romance and romantic suspense authors, compared with $5,000 for literary fiction authors and $3,500 for biography authors. The picture is similar in Britain, where a survey commissioned by the Authors' Licensing and Collecting Society found that primary occupation authors' median earnings from self-employed writing had fallen to £7,000, down 38.2% in real terms since 2018.

Set against those figures, a proposal deal has obvious appeal. An advance paid before the book is written can fund the writing itself. It also carries obligations: a delivery date, an agreed scope and, typically, an editor's expectations shaped by the proposal.

The risks on both sides

A proposal deal shifts risk in both directions. The publisher risks that the finished book will not match the proposal. The author risks committing to a book before fully understanding it, and to a deadline that may turn out to be unrealistic. Authors should check what their contract says happens if a manuscript is late or is not accepted, ideally with an agent or a lawyer.

For fiction writers, finishing first reduces those risks. The book already exists, the editor can judge it as a whole, and the author is not writing toward a promise.

The independent alternative

Independent publishing removes the proposal step altogether. Authors who self-publish decide when a book is ready and take on the costs and risks themselves. The Authors Guild survey found that full-time self-published authors reported a median book income of $12,800 in 2022, and that those publishing since at least 2018 reported a median of $24,000, up 76% from $13,700 in 2018. The trade-off is that no advance funds the writing. The route is also increasingly crowded: Bowker data reported by Publishers Weekly show that self-published output rose 38.7% in 2025 to more than 3.5 million print and ebook titles, against 642,242 traditionally published releases.

Choosing the right path

The right approach depends on both the book and the author:

• Nonfiction with a clear audience and an author with relevant expertise suits the proposal model.
• Debut fiction is usually best finished before querying.
• Memoir depends on the author's track record and platform.
• Any contract should be read for its delivery, acceptance and repayment terms.

A paradigm, not a shortcut

Selling a book before it is finished is a long-established practice in nonfiction, not a new trend. It can provide income and editorial guidance during the writing. It also binds the author to a plan. Understanding when the model applies, and what the contract demands, allows authors to use it on their own terms.
