A blank proposal page is a friction trap. Asking a model to “write a proposal for a branding project, make it compelling, suggest a package price” feels efficient. It is also how invented fees and overconfident timelines land in a document that looks ready to send. The client will treat your PDF as your offer. The model will not be on the call when scope expands.
This workflow is for freelancers and solopreneurs. It is not a lesson in what you should charge - for research hygiene without rate dictation, see pricing research, not price dictation.
Business scenario
Illustrative scenario, not a measured case: A solo marketer needs a proposal by Friday. They paste a long discovery-call transcript into a consumer chat and ask for a full proposal with three pricing tiers. The draft returns polished packages and round-number fees. Two of the deliverables were never discussed on the call. One fee is below the marketer’s minimum. Sending it “with light edits” would still ship commitments they did not choose.
Discovery notes often contain third-party names, budgets, and strategy. Redact or summarize before any paste. If the transcript is confidential, do not paste it - outline from memory in your own words first. See do not paste client secrets into AI.
Tool and workflow choice
Use AI for:
- Section outlines and headings
- Plain-language cleanup of text you wrote
- Alternative phrasings of a scope boundary you already decided
- Checklists of questions you still need to ask the client
Do not use AI for:
- Choosing your fee or discount
- Inventing milestones you have not capacity-checked
- Legal conclusions about contract terms
- Claims about guaranteed results
Truthful marketing still matters when proposals double as sales copy (FTC advertising and marketing; FTC crackdown on deceptive AI claims and schemes).
Step-by-step build
Step 1: Write the human spine first
Before opening a model, fill these lines yourself:
- Outcome the client asked for (in their words)
- In-scope deliverables you are willing to own
- Explicit out-of-scope items
- Assumptions (access, feedback turnaround, brand assets)
- Your fee or fee range (your number)
- Timeline you have actually checked against your calendar
- How acceptance / revisions work
If a line is blank, that is a discovery gap - not a prompt gap.
Step 2: Ask for structure only
Turn the following notes into a clear proposal outline with
section headings and short bullets. Do not invent deliverables,
fees, dates, guarantees, or case-study results that are not in
my notes. If something needed for a complete proposal is missing,
list it under "Questions for me" instead of filling it in.
Notes:
[paste only your spine - no confidential annexes]
Step 3: Paste your real commercial terms yourself
Copy fee, dates, and revision limits from your spine into the draft by hand. Do not ask the model to “suggest market rates” inside the same document you plan to send.
Step 4: Spin and invention check
Read the draft once looking only for:
| Watch for | Action |
|---|---|
| Deliverables you did not list | Delete or move to optional discovery |
| Fees or discounts you did not set | Replace with your numbers |
| ”Guaranteed” outcomes | Rewrite as process / deliverable language |
| Timeline padding that ignores your calendar | Recalculate yourself |
| Case results that sound like proof | Remove unless you have permissioned evidence (portfolio evidence) |
Never send a proposal whose price or delivery promises originated as model suggestions you did not independently adopt. If you cannot explain a number or a date without pointing at the chat, it is not ready.
Step 5: Human review rule
Sleep on it, or have a trusted peer review scope boundaries - not to set your price, but to catch overcommitment. Solo operators often borrow peer review habits from freelancer networks without treating chat output as counsel (Freelancers Union resources). For contract wording questions, use literacy prompts that produce questions, not legal answers (contract invoice literacy; related consumer-contract habit in contract literacy questions).
Keep a “proposal spine” template in your notes app with empty fields for fee and dates. Always fill those fields before any AI formatting pass. The order is the control.
Validation and fallback
Validation: every commercial number and date in the PDF appears in your pre-AI spine note.
Fallback: if the model invents packages, discard the draft and format the spine manually. Speed is not worth a bad promise.
EU-facing consumer offers should avoid misleading omissions about what is included (Unfair Commercial Practices Directive 2005/29/EC).
Shown shape: spine vs bad AI fill
Illustrative input (spine only): Outcome: launch email sequence for existing lead list. In scope: 5 emails, 1 revision round, plain-text + one branded template. Out of scope: list cleaning, paid ads, new brand system. Fee: [your number]. Timeline: 10 business days after assets received. Acceptance: written OK on email 1 before drafting 2-5.
Bad AI fill to reject: Adds “A/B testing program,” “guaranteed open-rate lift,” and a discount tier you never set.
Acceptable AI help: Turns the spine into headings and bullets without new commercial terms.
Close the loop with scope control
After the proposal is accepted, changes go through a scope change log, not a friendly chat rewrite. The proposal draft ownership card is the checklist for the drafting pass itself.
