Key takeaways

  • Structure your proposal around three core elements: the client's problem, your solution, and your pricing, so each section builds a clear case for why your business is the best choice.
  • Include real evidence such as case studies, client testimonials, and measurable results to build trust and show prospective clients what you can deliver.
  • Offer multiple pricing options at different levels so clients can choose what fits their budget, and use a pricing table to make the comparison easy to understand.
  • Keep your proposal as long as it needs to be to persuade the client, but prioritise clarity and accuracy by proofreading carefully and checking that all numbers and details are correct before sending.

What is a business proposal?

A business proposal is a formal document that outlines your services and persuades potential clients to choose your business. You send it to prospective clients to win projects or secure sales by showing why your solution fits their needs best.

Types of business proposals

Business proposals fall into two main categories based on how they're initiated:

  • Solicited proposals: Respond to a client's formal request for proposals (RFPs)
  • Unsolicited proposals: Reach prospects proactively without a formal request

Solicited proposals give you clear criteria and client information upfront. Unsolicited proposals work like cold pitches to attract new business opportunities.

The difference between a business plan and a business proposal

A business plan maps out your overall strategy, goals, and vision for success. It shows how your business operates and makes money. You can create a business plan using the free Xero business plan template.

A business proposal pitches a specific product or service to a prospective customer. It aims to make the sale by showing how your solution solves their problem.

How to write a business proposal

Writing a business proposal starts with addressing three core elements that win clients:

  • Problem: Identify the client's biggest pain point
  • Solution: Explain how you'll solve it better than competitors
  • Pricing: Present costs that demonstrate value

Each section of your proposal should build credibility and guide clients through your solution systematically. Follow these steps to structure your proposal:

  1. Title page

Create a professional first impression with your business name, client's name, submission date, and proposal title.

  1. Table of contents

Help clients navigate to their priority sections quickly.

  1. Executive summary

The executive summary gives clients a snapshot of why you're the best choice before they read the details. This works similarly to the executive summary in your business plan.

Include these elements:

  • introduce your business and key team members
  • highlight your track record and business goals
  • outline product and service benefits
  • showcase relevant milestones and client successes
  1. Problem statement

Demonstrate understanding by outlining the client's main challenge. Use specific data to support your analysis.

  1. Proposed solution

Your proposed solution shows the client exactly how you'll address their problem. Present your tailored approach with these elements:

  • list the specific deliverables you'll provide
  • explain the key benefits the client will gain
  • set a timeline for project completion
  • define success metrics to measure results
  • include visual elements like charts to illustrate your approach
  1. Qualifications

The qualifications section builds trust by showing why your business is the best choice for the job.

Include evidence such as:

  • case studies from previous clients with measurable results
  • client testimonials and social media endorsements
  • industry qualifications and certifications
  • years of experience in your field
  1. The timeline

The timeline shows clients when and how you'll deliver results.

For specific projects, outline a clear and realistic timeframe for each phase. Present this in a flowchart or roadmap with deadlines and step-by-step actions.

For general proposals, share typical timeframes your business works to, such as manufacturing times, shipping times, or service turnaround.

  1. Pricing, billing and legal

The pricing section is one of the most important parts of your proposal, especially since research shows the impact of pricing on profitability exceeds other marketing elements. How you structure it depends on the project size and proposal type.

For smaller projects and unsolicited proposals, a summary of fees is sufficient. For larger projects, provide a detailed cost breakdown so clients see exactly what they're paying for.

Consider offering multiple pricing options to give clients flexibility. For solicited proposals, check the RFP terms to ensure you meet their requirements.

Include any permits, licences, or regulatory costs required for the project. Note relevant changes published on the Companies House website.

  1. Terms and conditions

Terms and conditions clarify the legal and practical details of working together. Summarise key project details including timeline, pricing, and payment schedules.

Include items such as:

  • cancellation policies
  • deposit requirements
  • warranties
  • shipping terms

Ask a lawyer to review your terms and conditions before sending them to prospective clients.

  1. The acceptance

If the proposal is intended to function as an agreement or acceptance document, include a signature or acceptance section. Otherwise follow the client's procurement or contracting process. Include contact information so your client can follow up with any questions.

Business proposal tips

Winning business proposals stand out through strategic preparation and compelling presentation. These techniques help you close more deals and land more clients.

Start with an outline

Plan your structure and gather all necessary information before writing.

Include real data

Use specific metrics from business reporting software where appropriate. Consider charts, tables, or diagrams to make data easier to understand.

Use visuals

Enhance readability with relevant graphics like infographics, flowcharts, timelines, and comparison tables. Add captions to clarify their purpose.

Incorporate video

If the client's format allows, supplemental video can help explain your offering. Use short videos to bring your proposal to life, such as:

  • introduction to your proposal
  • testimonials from satisfied clients
  • demonstrations of your product or service

Add evidence from past clients

Build credibility through proof of your results. Include these types of validation:

  • case studies that show measurable results
  • testimonials that feature satisfied clients
  • reviews and rankings that come from third parties
  • customer stories that demonstrate impact
  • client lists that include recognisable names

Always obtain permission before sharing client information.

Use a call to action

Include a call to action so your audience knows what to do next. Include contact details so they can ask questions or clarify issues.

Provide pricing options, upsell and add on opportunities

Consider your client's budget and provide several pricing options: high, mid, and low. Include more services or features in higher-priced options, keeping in mind that only 15% to 20% of companies base their prices primarily on customer value, according to ICAEW research on value-based pricing. Use a pricing table to present your options clearly.

Include related services or products your business provides. This creates upselling opportunities and gives clients a fuller picture of what you offer.

Stay on brand

Allow your brand's personality through effective marketing to stand out. Demonstrate how you are better and different from your competitors, as even small differences in quality and competence can create positive differentiation that justifies premium rates.

Keep it simple

There's no set length for a business proposal. Your proposal should be as long as it needs to be to persuade the client.

Focus on being clear and concise, providing enough detail to solve their problem without overwhelming them. A simple project might need only a few pages, while a complex one may require more.

Accuracy

Be thorough and proofread your proposal. Check that your spelling and grammar are accurate and there are no typos. Pay attention to the details. Make sure your numbers and all information in your proposal are accurate.

Write a cover letter

A cover letter is a one-page summary that compels decision-makers to read your full proposal.

Include these essential elements:

  • provide contact information for easy follow-up
  • summarise the key benefits of your proposal
  • highlight why you're the best choice for the project
  • include a clear call to action

FAQs on business proposals

Here are answers to common questions about writing business proposals.

What's the difference between solicited and unsolicited proposals?

Solicited proposals respond to a formal request for proposals (RFPs) from a client. Unsolicited proposals are sent proactively to prospects without a formal request.

How long should a business proposal be?

There's no set length for a business proposal. It should be long enough to persuade the client while remaining clear and concise. Simple projects might need only a few pages, while complex projects may require more detail.

What's the most important section of a business proposal?

All sections are important, but the executive summary and pricing sections are critical. The executive summary gives clients a snapshot of why you're the best choice, while the pricing section shows the value you provide.

Should I include case studies in my proposal?

Yes, case studies provide proof of your results and build credibility. Include case studies from previous clients with measurable results, but always obtain permission before sharing client information.
