Step-by-Step Guide: Write a Proposal in 15 Minutes

Let us break down the process of writing a professional business proposal using Proposal Writing Software, from start to finish.

Minute 1–2: Choose a Proposal Template

Start by logging into your Proposal Writing Software. Most platforms offer a library of pre-built templates for industries like marketing, software development, consulting, construction, and AV services.

What to do:

Select a template that matches your service or project type
Ensure the template includes standard sections like introduction, scope of work, pricing, terms, and signature

Why it works: Templates give you structure, design, and content layout instantly—no need to format from scratch.

Minute 3–4: Customize the Client Details

Now, personalize the template with your client’s information. Good software integrates with CRM platforms, so it auto-fills client name, company, and contact info.

What to do:

Replace placeholder text with client name, logo, and project title
Add today’s date and proposal validity timeline
Update company branding such as logos, colors, and fonts

Why it works: Personalization increases trust and engagement. Clients feel like the proposal was made just for them.

Minute 5–7: Edit the Introduction and Project Overview

Your introduction should summarize the client’s goals and how your business can help. This is your elevator pitch.

What to do:

Use AI tools or content blocks to pull in relevant messaging
Keep the intro client-focused—talk about their challenges and your proposed solution
Edit the project overview to match the specific needs of this proposal

Why it works: Proposal Writing Software often stores pre-approved content snippets you can reuse to save time while keeping quality high.

Minute 8–10: Define Scope of Work and Deliverables

This section outlines what services or products you will deliver, timelines, and responsibilities.

What to do:

Select scope items from your saved service catalog
Use drag-and-drop tools to arrange tasks or milestones
Insert a timeline chart if supported by the software

Why it works: Proposal Writing Software lets you save and reuse service modules, meaning you don’t have to rewrite the scope every time.

Minute 11–12: Add Pricing and Payment Terms

Now, show your pricing in a clean, transparent format. Use itemized tables, subscription models, or packages—whichever suits your offer.

What to do:

Choose between flat fee, hourly rate, or tiered packages
Insert dynamic pricing tables that auto-calculate totals
Add notes about payment methods, deposits, and due dates

Why it works: Interactive pricing tables make it easier for clients to understand options. Some software even lets them select a package on the spot.

Minute 13: Insert eSignature and Approval Sections

The faster clients can approve, the sooner you can start. Add digital signature fields so they can sign directly in the proposal.

What to do:

Insert client and company signature fields
Enable notifications for when the proposal is signed
Add optional contract or terms of service if applicable

Why it works: eSignatures accelerate decision-making. With legal compliance and encryption, your digital proposal is both fast and secure.

Minute 14–15: Preview, Send, and Track

Before hitting send, preview the full proposal to ensure everything looks polished.

What to do:

Use the live preview mode in your Proposal Writing Software
Check for mobile and desktop responsiveness
Click “Send” or generate a shareable link
Enable real-time tracking to know when it’s opened

Why it works: Real-time tracking helps you follow up more effectively. You will know when the client opens the proposal and how long they spend on each section.

Bonus Tips to Save Even More Time

Save reusable content blocks like testimonials, case studies, and service descriptions
Use AI-powered suggestions to write intro text, headlines, or summaries
Automate follow-ups for unsigned proposals after 24 or 48 hours
Keep your branding assets stored within the software for one-click application
Integrate with CRM and billing systems to reduce manual data entry
