Writing Winning Proposals

A step-by-step guide to creating proposals that convert. From structure to storytelling, learn what makes clients say yes.

7 min read January 2025

A great proposal isn't just a list of what you'll do—it's a story about how you'll transform your client's situation. This guide walks you through Closed's 8-step proposal builder and how to make each section count.

The 8-Step Proposal Structure

Closed guides you through a proven proposal structure:

  1. Introduction – Set the stage and show you understand their situation
  2. Problem/Challenge – Articulate what they're facing
  3. Solution/Approach – Explain how you'll solve it
  4. Case Studies – Prove you've done this before
  5. Team – Introduce who they'll work with
  6. Pricing – Make it clear and easy to choose
  7. Timeline – Set expectations on delivery
  8. Sign-off – Make it easy to say yes

You can skip sections that don't apply or add custom content, but this structure works for most agencies.

Step 1: Introduction

The introduction sets the tone. Key elements:

  • Personalise it: Use their company name, reference your conversation
  • Show understanding: Briefly summarise what you know about their situation
  • Build excitement: Hint at the transformation you'll deliver

Example Opening

"Following our conversation last week, we're excited about the opportunity to help ACME Corp modernise their digital presence. You mentioned the current site isn't converting visitors—that's exactly the challenge we love to solve."

Step 2: Problem/Challenge

Before presenting your solution, demonstrate that you understand the problem. This builds credibility and makes your solution feel inevitable.

  • List the specific challenges they mentioned
  • Add any challenges they might not have articulated but you've identified
  • Quantify the impact where possible (lost revenue, wasted time, missed opportunities)

Pro tip: The problem section is where you show expertise. If you can articulate their problem better than they can, you've already started winning.

Step 3: Solution/Approach

Now explain how you'll solve their problem. This is where you differentiate yourself from competitors.

  • Be specific: Vague solutions feel like templates. Specific solutions feel tailored.
  • Explain your methodology: Why do you approach things this way?
  • Connect to outcomes: Don't just list activities—explain what each achieves

Closed lets you display your approach as a step-by-step process, which helps clients visualise the journey.

Step 4: Case Studies

Proof beats promises. Include 2-3 relevant case studies that demonstrate you've solved similar problems before. See our case studies guide for detailed tips.

Step 5: Team

Clients don't just buy services—they buy people. The team section humanises your proposal:

  • Include photos: Faces build trust
  • Highlight relevant experience: Focus on what's relevant to this project
  • Keep it brief: 2-3 sentences per person is enough

Store team profiles in your content library so you can quickly add the right people to each proposal.

Step 6: Pricing

The pricing section is often where proposals are won or lost. Make it clear and easy to understand. See our pricing tables guide for detailed tips on:

  • Choosing between fixed pricing, packages, and line items
  • Using optional add-ons to increase deal value
  • Setting up interactive pricing that updates in real-time

Step 7: Timeline

Set clear expectations about when things will happen:

  • Key milestones: What are the major checkpoints?
  • Delivery date: When will the project be complete?
  • Dependencies: What do you need from them to stay on track?

Tip: Be realistic. Over-promising and under-delivering destroys client relationships. It's better to set conservative timelines and beat them.

Step 8: Sign-off

Make it easy to say yes:

  • Summarise the investment: Remind them of the total
  • Enable e-signatures: Let them sign without printing anything
  • Include terms: Add any terms and conditions they need to accept
  • Create urgency: Optionally set an expiry date on the proposal

Writing Tips

Beyond structure, how you write matters:

  • Write for scanners: Use headings, bullet points, and short paragraphs
  • Focus on "you": Talk about their goals, not your capabilities
  • Avoid jargon: Use plain language they'll understand
  • Be confident: "We will" is stronger than "We would"
  • Proofread: Typos and errors undermine credibility

Using Templates

Don't start from scratch every time. In Closed, you can:

  • Clone proposals: Duplicate a successful proposal and customise it
  • Use templates: Start from pre-built templates for common project types
  • Build your content library: Store reusable sections (case studies, team bios, service descriptions)

Templates speed up your process while ensuring consistency. Just make sure to personalise—clients can spot a template from a mile away.

Summary

A winning proposal tells a story: here's your problem, here's how we'll solve it, here's proof we've done it before, here's what it costs. Each section builds on the last, leading naturally to the signature.

Quick Checklist
