How to Write a Business Proposal with GitHub Copilot

GitHub Copilot, GitHub's AI assistant, is not limited to code generation. Thanks to its natural language understanding capabilities, it can help you write professional documents, including business proposals. By using GitHub Copilot Chat directly in your editor, you can structure your offer, craft compelling arguments, and personalize each section according to your prospect's profile. This tutorial guides you step-by-step from a client brief to a complete, persuasive, and professional business proposal. Whether you are a freelancer, consultant, or corporate salesperson, you will discover how AI accelerates your writing process while maintaining a high level of quality and relevance.

Prerequisites

1.Have an active GitHub Copilot subscription (Individual, Business, or Enterprise)
2.Have Visual Studio Code installed with the GitHub Copilot and GitHub Copilot Chat extensions
3.Prepare key information about the prospect: company name, industry, expressed need, and estimated budget
4.Have a project folder open in VS Code to store the proposal files

Steps

Define the context and client brief

Start by creating a Markdown file (proposal.md) in your project. Open GitHub Copilot Chat and provide it with all contextual information about your prospect and their need. The richer the context, the more relevant the proposal. Include the industry, company size, problem to solve, and your available solutions.

I need to write a business proposal for [COMPANY_NAME], a [INDUSTRY] company with [X] employees. Their main need is [DESCRIBE_NEED]. My company offers [DESCRIBE_YOUR_SERVICES_PRODUCTS]. Estimated client budget: [AMOUNT]. Generate a complete business proposal structure in French with the main sections.

Tip: Create a context.md file with all the prospect information. Copilot Chat can reference it with @workspace to enrich its responses throughout the writing process.

Write the executive summary and hook

The executive summary is the first section read by the decision-maker. It must grab attention in under 30 seconds. Use Copilot Chat to generate a hook focused on client benefits rather than your technical features. Ask for multiple variants and select the most impactful one.

Write a 200-word executive summary for this business proposal. The tone should be professional yet engaging. Start with the client's problem, then our solution, and end with expected results (ROI, time savings, cost savings). Propose 3 variations of the opening hook.

Tip: Ask Copilot to rephrase using the specific vocabulary of your prospect's industry. A summary that speaks the client's language is always more convincing.

Detail the technical offer and action plan

This section is the heart of your proposal. Describe precisely what you will deliver, project steps, deadlines, and deliverables. Use Copilot to structure a clear action plan with milestones and responsibilities. Ask it to format everything in a Markdown table for easy reading.

Based on the provided context, generate the 'Our Solution' section with: 1) A detailed description of the proposed approach in 3-4 paragraphs, 2) An action plan in a Markdown table with columns Phase, Description, Deliverables, Duration, 3) Measurable success indicators for each phase. Use an expert and reassuring tone.

Tip: Use Copilot's inline feature (Ctrl+I) directly in your Markdown file to adjust specific paragraphs without losing the global document context.

Build the pricing section and terms

The pricing grid should be transparent and justified. Use Copilot to present your rates in a structured way, with options that allow the client to choose. Include payment terms, guarantees, and important clauses. A good pricing presentation reassures and facilitates decision-making.

Generate a professional pricing section including: 1) A table with 3 packages (Essential, Premium, Custom) with prices, included services, and commitment duration, 2) Payment terms (deposit, schedule), 3) A satisfaction guarantee clause, 4) Offer validity period. Indicative amounts based on [YOUR_PRICE_RANGE].

Tip: Ask Copilot to justify each line item by the value delivered to the client rather than the cost. The value-based pricing approach is more convincing than a simple price list.

Finalize, proofread, and optimize the proposal

Before sending, use Copilot Chat for a full review. Ask it to identify argumentative weaknesses, inconsistencies, and errors. Also have it generate the conclusion with a clear call to action and concrete next steps. Take the opportunity to add relevant client testimonials or case studies.

Proofread this complete business proposal and: 1) Identify argumentative weaknesses or unconvincing passages, 2) Check consistency of numbers and deadlines, 3) Write a compelling conclusion with a clear call to action and the next 3 steps, 4) Suggest where to insert client testimonials or social proof to strengthen credibility.

Tip: Export your Markdown file to PDF using an extension like Markdown PDF for VS Code. Copilot can also help you add custom CSS for a professional visual rendering.

Common mistakes to avoid

✗Providing too vague a context to Copilot: without precise information about the prospect and their needs, the AI generates generic content that won't convince anyone
✗Copy-pasting Copilot's output without proofreading or personalization: the generated content must always be adapted, verified, and enriched with your business expertise
✗Neglecting structure and formatting: a poorly organized business proposal loses the reader, even if the content is relevant — use headings, tables, and bullet lists
✗Forgetting to verify figures and commitments generated by the AI: Copilot may invent statistics or unrealistic deadlines that must be validated
✗Not including a clear call to action: without concrete next steps (meeting date, signature, deposit), the proposal remains a passive document

FAQ

Is GitHub Copilot suitable for writing business documents or only code?

GitHub Copilot, and especially Copilot Chat, excels at generating structured text in natural language. By working in Markdown files, you can leverage its capabilities for any type of professional document. Its strength lies in its understanding of your workspace context, allowing it to produce coherent and relevant content for your business proposals.

How do I ensure the generated proposal does not look like generic AI content?

The key is to provide ultra-specific context: prospect data, references to previous exchanges, industry vocabulary, and concrete use cases. Systematically ask for multiple variants and combine the best parts. Add your own anecdotes, real case studies, and testimonials. Copilot's role is to speed up the structure and first draft, not to replace your expertise.

Can I use Copilot to customize an existing proposal for a new prospect?

Absolutely. Open your proposal template in VS Code and use Copilot Chat to adapt each section to the new context. Reference the existing file with @file and provide the new prospect's information. Copilot will adjust the tone, examples, and arguments while preserving your proven structure. This is one of the most effective ways to save time.
