Write a client proposal that gets signed without three rounds of edits
Turn a scoped project into a one-page proposal a client can approve on first read — deliverables, timeline, and price stated plainly, with nothing for them to get stuck on.
The prompt
Ready to copy — highlighted parts are example details you can swap.
You are a proposal writer for a small service business. Write a one-page client proposal that a non-technical decision-maker can approve without asking us to explain it first. Context: - Client: Meridian Dental Group - Project: a 6-week rebuild of their booking website - Deliverables: new booking site, mobile checkout, 3 months of hosting - Timeline: design wks 1-2, build wks 3-5, launch wk 6 - Price and terms: $4,200 total, 50% upfront, 50% on launch - Our business: Northline Studio Task: 1. Open with one sentence stating the problem this project solves for Meridian Dental Group, in their language, not ours. 2. List deliverables as a short, scannable list — no filler adjectives. 3. State the timeline with named milestones, not just a duration. 4. State price and payment terms plainly, in the same section as the deliverables, not buried at the bottom. 5. Close with exactly one next action (e.g. "reply to confirm and we'll send the contract") — not three optional ones. Format: plain text suitable for pasting into an email body, under 300 words, no headers that just repeat "Introduction" or "About Us". No em dashes.

Why this works
Proposals stall for one of two reasons: the reader can't find the number, or they can't tell what to do next. This structure fixes both — price sits next to the deliverables it buys instead of at the bottom where it reads like a surprise, and the proposal ends with a single explicit action instead of a vague "let us know your thoughts," the easiest sentence in business writing to ignore. Opening with the client's problem in their own words, not a list of your capabilities, is what makes a proposal read as written for them instead of a template with their name swapped in.
What you get back
Subject: Proposal — Booking site rebuild for Meridian Dental Group Right now, patients dropping off mid-booking on mobile is costing Meridian real appointments. This proposal fixes that. What you get: - Rebuilt booking site, mobile-first checkout - 3 months of hosting included - Staff walkthrough before launch Timeline: 6 weeks — design (wks 1-2), build (wks 3-5), launch (wk 6). Price: $4,200 total — 50% to start, 50% on launch. Reply to confirm and we'll send the contract to get started this week. — Northline Studio
