What you'll accomplish
A proposal used to start with you digging through old Google Docs, copying whichever SOW felt closest, then rebuilding the pricing table by hand. After this setup, you describe what a prospect needs and Claude drafts a full proposal in your voice, priced the way you actually price, in a couple of minutes.
What you'll need
If you don't already have one, this takes two minutes.
What you should see: A chat window with a message box at the bottom and a sidebar on the left. Troubleshooting: If the signup form rejects your email, try a different browser or clear cookies for the site first.
Projects keep a set of instructions and documents separate from your regular chats, so proposal work never gets mixed up with anything else you use Claude for.
What you should see: A blank project page with options to set instructions and add content. Troubleshooting: If you don't see a Projects option, you may be on an older interface layout. Check your account or workspace settings for a "Projects" or "Workspaces" toggle.
This is the system prompt every proposal draft will follow.
What you should see: Your instructions saved and visible whenever you reopen the project. Troubleshooting: Keep this to a few short paragraphs. Long instructions don't improve accuracy. They just crowd out space better spent on real proposal examples.
What you should see: A list of uploaded files in the project's knowledge panel. Troubleshooting: If a file won't upload, check the format. PDFs, Word docs, and plain text all work reliably. Scanned image-only PDFs sometimes fail to extract text, so retype or re-export those first.
Confidential data caution: Past proposals often name the client, their budget, and internal numbers you quoted them. Before uploading, strip client names and swap in a placeholder like "Client A," and leave out anything covered by an NDA with that account. Your own pricing framework is fine to upload since it's your document, not a client's.
What you should see: A full draft with sections matching what you described in your instructions, referencing pricing logic similar to your uploaded rate sheet. Troubleshooting: If the draft ignores your pricing structure, confirm the rate sheet actually uploaded (check the knowledge panel) and name it directly in your prompt: "use the pricing tiers from the rate sheet I uploaded."
Turn call notes into a proposal:
Here are my raw notes from today's discovery call: [paste notes]. Draft a
proposal using our standard structure, and flag anywhere the scope sounds
vague so I can tighten it before sending.
Adjust pricing for a smaller budget:
The client's budget is tighter than our standard tier for this scope. Show
me two options: a reduced-scope version closer to their range, and our full
recommended scope, so I can present both.
Rewrite a section in a different tone:
Rewrite the introduction paragraph to sound warmer and less formal. This
client is a small local business owner, not a corporate marketing team.
Check a proposal against your own standards:
Review this draft proposal against our usual structure. Does it call out
scope, deliverables with quantities, timeline, pricing, and what's out of
scope clearly? Point out anything missing.
Summarize what changed between two versions:
Compare this revised proposal to the original draft and summarize what
changed, so I can explain the update to the client in one paragraph.
