The Problem
Writing proposals is one of the most expensive tasks in a service business. A senior team member spends three to four hours putting together a single document — pricing, scope, timeline, executive summary, the lot. Multiply that by 10-20 proposals a month and you've got hundreds of hours per quarter spent on documents that prospects often skim in three minutes.
Worse, the quality varies. The proposal you send on a Tuesday morning when you're fresh is sharper than the one you send on a Friday afternoon when you're tired. Inconsistent proposals lead to inconsistent close rates.
Claude Cowork solves this in two ways. First, it does the heavy lifting — turning a short brief into a complete first draft in under two minutes. Second, it enforces consistency. Every proposal hits the same structure, same persuasive arc, same level of polish, regardless of when or who's writing it.

- Builds executive summaries that prospects actually read
- Assembles pricing and scope from your standard packages
- Tailors tone for the specific industry and decision-maker
- Generates persuasive case for action and clear next steps
- Adapts past winning proposals to new prospects in seconds
How to Set It Up
1
Gather your three best past proposals
Pick proposals you're proud of — ones that won. These become Claude's reference material for tone, structure, and persuasive style.
2
Document your service offering
List your packages, pricing, deliverables, and timelines in a single document. Claude needs this as ground truth to assemble accurate proposals.
3
Build a master proposal prompt
Combine the past proposals + service document + a structure outline (problem, approach, scope, timeline, pricing, next steps) into one master prompt template.
4
Drop in the client brief
Each new proposal starts with you pasting the discovery call notes. Who they are, their pain, their goal, their budget. Claude does the rest.
5
Review and personalise
The first draft is usually 90% there. Add the genuinely personal touches — a reference to something they said in the call, a tailored opening — and send.

PROPOSAL: AI WORKFLOW IMPLEMENTATION
Prepared for Northbridge Recruitment
EXECUTIVE SUMMARY
Northbridge is losing 15+ hours per recruiter per week to administrative tasks that AI can handle in minutes. Our 6-week implementation package delivers a custom-built workflow system, fully trained team, and 60 days of support — designed to recover that time so your senior recruiters can focus on placements, not admin.
THE PROBLEM
You've built a strong recruitment business on Bullhorn, but the volume of candidate briefings, client updates, and routine emails is consuming your team's most valuable hours. Every hour your senior recruiters spend on a candidate brief is an hour they're not placing the next role.

We'll audit your current workflows, identify the highest-leverage automation opportunities, and build a custom prompt library tailored to recruitment. Your team will be trained to use Claude Cowork for the specific tasks that eat their week — candidate briefings, client emails, job spec drafting, weekly reports.

Frequently Asked Questions
Can Claude write proposals tailored to my business?
Yes — when you give Claude your service offering, pricing structure, typical client profile, and a few past proposals as reference, it produces drafts that match your style and approach. The first time takes 10 minutes of setup. Every proposal after that takes 2 minutes.
Will my proposals all sound the same?
Only if you let them. Claude follows the structure you provide but personalises each proposal based on the client's specific situation, pain points, and goals. Good prompts produce proposals that feel hand-written for each prospect.
Can it handle complex pricing and scope?
Absolutely. You can give Claude pricing matrices, package tiers, or custom scope sheets and it will assemble the appropriate combination based on the client brief. Particularly useful for agencies and consultancies with modular service offerings.
How long does setup take?
About 30 minutes the first time — you create a proposal template prompt with your services, pricing, tone, and any standard sections. After that, every new proposal takes 2-5 minutes to generate from a brief.
Can Claude write the executive summary too?
Yes, and this is often the highest-value part. Once Claude has drafted the main proposal, you can ask it to extract a punchy executive summary that captures the key points in 100-200 words — perfect for prospects who scan rather than read.
