The business in one offer
Who it serves
Self-published nonfiction authors who have finished editing and formatting their book and want a final check before printing. They want a clean book that looks professional and avoids embarrassing errors that readers may notice in reviews.
What to sell first
A final proofread of a formatted nonfiction PDF up to 60,000 words: marking typos, missing or repeated words, inconsistent spelling and capitalization, layout issues such as widows and orphans, and a short style sheet, returned within ten business days. Excluded: rewriting, restructuring, fact-checking, formatting fixes and multiple rounds.
A clearly defined final proofread separates your service from editing, making it easier to quote and deliver. Authors understand what they will receive, and you can use a consistent checklist across projects.
What could it cost to start?
This is an original example budget for the limited pilot described above. It is not a researched market average or a complete quote for every location.
| Item to price | Example allowance |
|---|---|
| Style manual online subscription, one year | $60.00 |
| PDF annotation software, three months | $60.00 |
| Grammar checking tool, three months | $45.00 |
| Professional liability insurance allowance | $350.00 |
| Simple website and sample page offer | $150.00 |
| Business registration and bank account | $300.00 |
| Example total | $965.00 |
What this assumes—and excludes
Assumes you have strong language skills, a computer and a quiet workspace. Excludes editing training, office rent, owner pay and local license fees. Insurance and software costs vary, so get quotes before setting prices.
Collect actual supplier, insurance and local-authority information. Add a reserve for delays and unexpected costs; the example total is not a funding recommendation.
How the unit economics work
At an assumed $900.00 per manuscript and $15.00 in direct costs, contribution is $885.00 before monthly fixed costs, owner pay and taxes. With 22 all-in working hours per unit, that is $40.23 per delivery hour before those deductions. These inputs illustrate the arithmetic; they do not establish a market price or expected earnings.
The example also allows $70.00 in monthly fixed costs. Include unpaid acquisition and administrative time when deciding whether the offer is worthwhile.
Try your own numbers
These are editable planning assumptions, not prices we have verified. Calculations stay in your browser.
Operating result = (price − direct cost) × units − monthly fixed costs. Before owner pay, taxes, financing and startup recovery. At these inputs, delivery requires 220 hours per month, plus any work not included in your per-unit estimate. Sales volume is a scenario, not a forecast.
How to find the first customers
Test a small offer before scaling traffic. Record the source of each enquiry, whether it fits the offer, and whether the buyer pays.
- Offer to proofread a sample chapter for two indie authors in your network, and ask for permission to share before-and-after pages without revealing confidential details.
- Join author communities that allow service posts and share a short checklist on what proofreading covers, with a link to request a sample page.
- Contact book designers and formatters who work with indie authors, and offer to proofread after layout, with a clear referral agreement.
- Track each project's word count, hours and error types, and use that data to refine your price and estimate future jobs.
What to validate before spending more
- Proofread a sample manuscript on a timer and count the hours. If 60,000 words takes longer than 24 hours, adjust the price or limit.
- Ask three authors how they define proofreading and what they expect, and adjust your scope description to prevent misunderstandings.
- Test whether authors prefer pricing per word or per project by offering both on sample quotes and noting which they choose.
- Check whether your city requires a business license for home-based writing services and keep a record of the answer.
The operational catch
Authors often send manuscripts that still need copyediting, hoping proofreading will fix everything. If you rewrite sentences at proofreading rates, you lose money and miss the scope. Ask for a sample, assess its readiness, and recommend copyediting first when needed.
A practical way to fund the first step
Collect a deposit before starting and the balance on delivery, and keep tools on monthly plans. Use early project payments to buy the style manual and insurance.
Separate cash already available from money still to earn. Count only proceeds after direct expenses, and do not spend customer funds needed to fulfill their existing orders.
Questions before you start
What is the difference between proofreading and copyediting?
Copyediting improves clarity, grammar and consistency at the sentence level, while proofreading checks a nearly final document for errors and layout issues. Explain this difference in your offer.
Should I proofread in Word or PDF?
Final proofreading usually happens on the formatted PDF so you can catch layout errors. Use comment tools to mark issues without changing the file.
How many errors should I expect?
It varies widely. A well-edited manuscript may have few errors, while a rushed one may have many. A sample page helps you judge the workload before quoting.
