What is a business proposal?

A business proposal is a formal document you send to a prospective client to win a project or make a sale. It outlines the service you'll offer and explains why they should choose you over competitors.

Types of business proposals

Business proposals are commonly categorised as solicited or unsolicited:

• Solicited proposal: requested by a potential customer, often through a request for proposal (RFP). However, organisations are often selective, with research showing they respond to just 65% of the RFPs they receive on average. The buyer typically provides requirements and evaluation criteria, though the amount of client information available varies by procurement.
• Unsolicited proposal: similar to a cold pitch. You send it to prospective clients without a prior request or established relationship to attract new business.

The difference between a business plan and a business proposal

A business plan is an internal roadmap showing your overall strategy, goals, and how your business will make money. You can find out more about business plans to get started.

A business proposal is an external pitch to sell a product or service to a prospective customer. It focuses on solving the client's problem and winning their business.

How to write a business proposal

A common proposal-writing approach is to address the three Ps:

• Problem statement: the customer's biggest pain point
• Proposed solution: how your business solves the problem better than competitors
• Pricing: how much the solution costs compared to alternatives

A strong business proposal follows a clear format. The sections you include will depend on your client and context, but most proposals cover the following:

1. Title page

Your title page sets the tone and must look professional. Include:

• your name
• your business's name
• the recipient's name
• the date submitted
• the title of your proposal

2. Table of contents

The table of contents allows your potential client to see what's in your proposal and lets them skip to the information they consider most important.

3. Executive summary

Your executive summary explains why your business meets the client's needs and why you're better than competitors. It should:

• introduce your business and key team members
• highlight your business goals and track record
• outline the benefits of your products or services
• showcase milestones and previous clients

4. Problem statement

Outline the main problem your potential client wants to solve. This shows you understand their pain points.

Use data to back up your argument. Be specific about the impact of the problem on their business.

5. Proposed solution

Explain in detail how your solution solves the client's problem. Your solution should be specific and personalised.

Include:

• what you plan to provide
• the benefits of your proposed solution
• your proposed timeline (for specific projects)
• how you'll measure success

Use charts and graphs to improve clarity when they present relevant information accurately and match your client's needs.

6. Qualifications

Use this section to build trust and explain why your business is the best choice. Include:

• case studies of previous clients
• client testimonials
• social media endorsements or praise
• relevant industry qualifications
• certifications and years of experience

7. Timeline

For specific projects, outline a clear and realistic timeframe showing how and when you'll complete each part. Present this in a clear format that suits the client's requirements. Options include a flowchart, roadmap, or milestone schedule with deadlines and step-by-step actions.

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

8. Pricing, billing and legal

This is one of the most important sections. Structure it based on your project size and proposal type:

• Smaller projects or unsolicited proposals: include a summary of fees or potential fees
• Larger projects: provide a detailed cost breakdown showing what clients pay for
• Solicited proposals: check the client's RFP terms to ensure you meet their requirements

Consider offering pricing options to give clients flexibility. If permits or licences are required for the project, include them in the section most appropriate to the client's requirements.

9. Terms and conditions

Clarify your terms and conditions, including:

• timeline
• pricing and payment schedules
• cancellation policies
• deposits
• warranties
• shipping

Get your terms and conditions checked by a lawyer before sending them to prospective clients.

10. Acceptance

Where appropriate, leave a space for signatures so your client can sign when they accept your proposal. Keep in mind that many proposals are accepted through a separate contract or purchase order rather than by signing the proposal itself. Include your contact information for any follow-up questions.

Business proposal tips

Make your proposal stand out from competitors with these approaches.

Start with an outline

Plan out everything in an outline before you begin writing. Make sure you have all the key information you need and research anything you're missing.

Include real data

Use specific data that demonstrates the value of your proposal. Present your data in flowcharts or graphs to make it easy to scan.

Use visuals

Include visuals to break up and enhance longer proposals. Effective visuals include:

• infographics
• flowcharts
• timelines
• photographs
• organisational charts

Make sure visuals are relevant, not just decorative. Add captions or explanatory notes if the purpose isn't obvious.

Incorporate video

A short video can strengthen your proposal and increase interest. This works well for online proposals or PDFs where the client accepts that format.

Effective video types include:

• an introduction to your proposal
• client testimonials
• a product or service demo

Add social proof

Client references, testimonials, and case studies can strengthen your proposal when they're relevant and you have permission to use them. Positive reviews or case studies can help convince your clients to accept.

Types of social proof include:

• case studies
• testimonials
• reviews and rankings
• customer stories
• previous client logos

Make sure you have approval to share this information to avoid breaching privacy.

Use a call to action

Tell your audience exactly what to do next after reading your proposal. Include contact details so they can ask questions or clarify any issues.

Provide pricing options

Consider your client's budget and offer several pricing options (high, mid, low) with added value at higher price points. Use a pricing table to present your options clearly.

Include other services or related products your business provides. This creates opportunities to add extras and shows clients the full scope of what you offer.

Stay on brand

Let your business's character stand out. Use consistent colours, fonts, and messaging that demonstrate how you're different from competitors.

Keep it simple

Avoid business jargon and keep sentences short. The right length depends on the client's instructions and offer complexity. Clarity matters most.

Provide enough detail to persuade the decision-maker without overwhelming them.

Check for accuracy

Proofread your proposal thoroughly before sending. Check that:

• spelling and grammar are correct
• there are no typos
• all numbers are accurate
• all information is up to date

Write a cover letter

Write a cover letter to send with your proposal. A strong cover letter convinces the decision-maker to read your full proposal.

Include:

• your contact information
• a brief introduction to your business and services
• concise details about the client's problem and your solution
• a strong conclusion highlighting the main benefit you'll deliver
• clear next steps for the prospective customer

Common business proposal mistakes to avoid

Avoiding common errors helps strong proposals succeed. Many teams overlook tracking. For instance, only 35% of teams track the overall revenue won from their proposals.

Avoid these common mistakes:

• Using generic templates: Tailor every proposal to the specific client and their needs.
• Burying pricing information: Be transparent about costs early to build trust.
• Overcomplicating language: Use plain language that any reader can understand.
• Skipping proofreading: Typos and errors signal carelessness to potential clients.
• Ignoring the client's brief: Address every requirement in the RFP or initial request.
• Missing follow-up details: Include clear next steps and your contact information.

How to follow up on your proposal

Sending your proposal is just the first step. A thoughtful follow-up can improve your chances of winning the work.

1. Wait three to five business days before your first follow-up, unless the client specified a different timeline.
2. Send a brief email asking if they received the proposal and if they have any questions.
3. Offer to clarify any sections or provide additional information they might need.
4. Set a reminder to follow up again in another week if you don't hear back.
5. Redirect your efforts. If you've followed up twice without hearing back, focus your energy on other opportunities.

Keep follow-ups professional, helpful, and respectful of the client's time. Your goal is to make it easy for the client to say yes.

FAQs on business proposals

Here are answers to common questions about writing business proposals.

How long should a business proposal be?

There's no fixed length. The right length depends on the client's instructions and offer complexity. Focus on addressing their needs without overwhelming them.

What's the difference between a business proposal and a quote?

A quote lists prices for specific products or services. A business proposal is more comprehensive, explaining the problem, your solution, qualifications, and pricing together.

Should I include pricing in every business proposal?

Yes, in most cases. Clients expect pricing information to make decisions. If exact pricing isn't possible, provide a range or explain how you'll determine final costs.

How soon should I follow up after sending a proposal?

See the follow-up section above for detailed guidance. Generally, wait three to five business days unless the client specified otherwise.

Can I reuse the same proposal for different clients?

Use templates as a starting point, but personalise each proposal to address the specific client's needs and situation.
