You have a finished manuscript, or a proposal and a clear sense of the reader you are writing for. Now comes the decision that colours everything afterwards: pursue a traditional publisher, or publish the book yourself? Neither route is the high ground. They trade different things — money, time, control — and the right answer depends on your book, your audience and what you want the book to do for you.

What Each Route Actually Involves

For most trade non-fiction in the UK, the traditional route means finding a literary agent rather than approaching publishers directly. Non-fiction is usually sold on a proposal: an overview, a chapter outline, a sample chapter, a note on who will buy the book and a short author biography. The agent takes that proposal to publishers and negotiates an advance against royalties.

The publisher then handles structural editing, copy-editing, design, printing, distribution, sales into shops and, at least in theory, some marketing. You write, you respond to edits, and you are paid royalties once the advance has earned out.

Self-publishing means becoming the publisher. You commission the editing, the cover, the typesetting and the ebook files. You buy the ISBNs, arrange print and distribution, and do the selling. In return you keep a much larger share of each sale and make every creative decision yourself.

Costs: Who Pays, and When

With traditional publishing you are not usually asked for money. The publisher invests in production and carries the commercial risk. Your costs are time, patience and the agent's commission, deducted from your earnings — typically around fifteen per cent for UK and US rights and twenty per cent for translation and other subsidiary deals. Advances for a first non-fiction book can be modest, and the marketing budget is rarely as generous as authors hope.

Self-publishing is a business you fund yourself. Expect to pay for:

• Developmental or structural editing, so the argument and the shape of the book hold up
• Copy-editing and proofreading
• Indexing, which non-fiction readers and librarians notice when it is missing
• Cover design and interior typesetting
• Ebook conversion
• ISBNs, bought in the UK from Nielsen, plus barcode artwork
• Print setup, whether through print-on-demand or a short offset run
• Website, email list and advertising

Costs vary enormously with length, complexity and suppliers, so gather fixed quotes from at least three people before committing. A book published on a shoestring can still sell well. A book with a homemade cover and no editing usually will not.

Tax and VAT treatment for self-published authors is not something to guess at. Speak to an accountant who has worked with writers before you set prices or register for anything.

Royalties: Compare Total Earnings, Not Percentages

Traditional royalties on print are usually a single-digit or low-teen percentage of the retail price, with higher rates on ebooks and lower rates on some export and discount sales. Your agent's commission comes off first. The compensation is volume: a publisher's sales team can put your book in front of buyers you would never reach alone.

Self-published authors keep whatever remains after the platform's cut and the printing cost, which is often a far higher proportion of the retail price. That looks excellent per copy, and for a specialist book with a defined audience it can be genuinely worthwhile. It looks less excellent if you sell two hundred copies because nobody knew the book existed.

The useful question is not which royalty is higher, but which route is likely to earn more over the realistic life of this book, after your own costs and hours. Be honest about the hours.

Timeline: Two Very Different Clocks

Traditional publishing runs on other people's calendars. Finding an agent can take months and usually involves a stack of rejections first. Once a deal is signed, a year or more before publication is normal, and your book may be scheduled around seasonal lists.

Self-publishing runs on yours. A few months from finished manuscript to published book is realistic if you book editors and designers early and work in parallel rather than in sequence. Speed helps when your subject is timely, when you are speaking at events, or when you want to test demand before writing a second book. It does not help if it means skipping the editing.

Creative Control and What You Give Up

With a traditional deal you hand over a degree of control. Cover design, title, jacket copy, price and publication date are usually the publisher's decisions, made for commercial reasons you may not fully see. You may be asked to cut a chapter or reframe an argument for a wider readership. Some authors find that process sharpens the book. Others find it maddening.

Self-publishing gives you the final word on every element, which is exactly what some subjects need. Local history, handbooks for a small trade or profession, family memoirs, guides for a specific condition or hobby, and books tied to a course or consultancy often make poor commercial sense for a trade publisher and very good sense as self-published titles with a clear audience.

Whichever route you take, hire people who will tell you when something is not working. Agreement is cheap; good editing is not.

Which Route Suits Which Book

Signs the traditional route fits

• You want your book in bookshops, libraries and review pages
• Your subject has broad, general-reader appeal
• You would like translation, serial and other rights handled for you
• You would rather write the next book than run a small publishing business
• You can wait a year or more to see the book on a shelf

Signs self-publishing fits

• You already have an audience through a newsletter, course, clinic, society or speaking work
• You write for a defined niche that a trade list would consider too small
• You need the book available within months
• You sell directly at events, workshops or from your own website
• You want to keep all rights, set your own price and control every edition

A Practical Way to Decide

1. Define what success means. Copies sold, speaking invitations, clients, credibility with peers, or income? The answer points to one route more often than any royalty table does.
2. Test the traditional market first. Submitting to agents costs nothing but time. Set yourself a deadline and a set number of agents, and treat the response as information rather than a verdict.
3. Price the self-published version properly. Get quotes for editing, cover, typesetting and indexing before you commit. If you are buying your ISBNs, buy your own rather than accepting a platform's free one, which usually ties that edition to a single retailer.
4. Be honest about marketing. A publisher will not do it all for you. Self-publishing means you do all of it, for as long as the book is on sale. If you will not enjoy that work, say so now.
5. Get the paperwork checked. Contracts are contracts, whether they come from a publisher or a printer. Organisations such as the Society of Authors offer guidance to members, and a solicitor who knows publishing is worth the fee.

Whichever way you go, keep your rights where you can, build your own email list, and treat the book as a long project rather than a single launch day. The authors who do well are rarely the ones who picked the supposed right route. They are the ones who matched the route to the book they had actually written.
