What is a business proposal?

A business proposal is a formal document you send to prospective clients to win new work. It outlines your solution to their specific problem, demonstrates your expertise, and explains why they should choose you over competitors.

Why you need a business proposal

A strong proposal does more than state a price. It proves you understand the client's challenge and have a clear path to solve it.

A well-written proposal helps you:

• Look professional: Present your business as credible and organised
• Manage expectations: Clarify scope, timeline, and deliverables upfront
• Build trust: Show you've listened and can deliver results
• Win more work:Turn prospects into paying clients

Types of business proposals

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

• Solicited proposals: Requested by potential clients through a request for proposal (RFP). You'll have clear criteria and detailed client information, making these easier to write and more likely to succeed.
• Unsolicited proposals: Sent proactively to attract new business without a formal request. These require more research but can help you reach clients who haven't considered your services yet.

The difference between a business plan and a business proposal

These two documents serve different purposes:

• Business plan: A roadmap for your business that outlines strategy, goals, and how you'll make money. It's an internal document for planning and securing funding. You can create a business plan using our free template.
• Business proposal: A pitch to win a specific client or project. It focuses on solving the prospect's problem and making the sale.

How to write a business proposal

Writing a business proposal starts with understanding what makes one effective. Every winning proposal addresses three core challenges for your prospective client:

• Identify the problem: Define the customer's biggest pain point with specific details
• Present your solution: Explain how your business solves their problem better than competitors
• Demonstrate value: Show how your pricing delivers superior value compared to alternatives

Your proposal should follow a structured format with these essential sections:

Research your client and opportunity

Before you start writing, gather the information you need to make your proposal relevant and compelling.

For solicited proposals, review the RFP carefully. Note the client's stated requirements, evaluation criteria, and submission deadlines. For unsolicited proposals, research the prospect's business, industry challenges, and competitors.

Understanding your client's situation helps you tailor your solution and demonstrate that you've done your homework. It's the difference between a generic pitch and a proposal that speaks directly to their needs.

Title page

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

Table of contents

Help clients navigate your proposal quickly and find the information most important to their decision.

Executive summary

The executive summary is a snapshot of your entire proposal. It presents your strongest case for why the client should choose you over competitors.

This section should:

• Introduce your business and key team members who'll work on their project
• Demonstrate your track record of success and relevant experience
• Highlight the specific benefits your products or services deliver
• Showcase relevant milestones, case studies, and previous client successes

Problem statement

Demonstrate your understanding by outlining the client's main challenge with specific details and supporting data. This proves you've done your research and understand their pain points.

Proposed solution

The proposed solution section explains exactly how you'll address the client's problem. Present your tailored approach with enough detail to build confidence.

Include:

• Detailed methodology: Explain exactly what you'll provide and how you'll deliver it
• Measurable outcomes: Define success metrics and how you'll track progress
• Project timeline: Provide realistic deadlines for each phase of work
• Visual elements: Use charts, graphs, or diagrams to illustrate complex concepts

Qualifications

Use this section to build trust. Explain why your business is the best one for the job and why they should choose you.

You can include:

• case studies of previous clients
• client testimonials
• social media endorsements or praise
• relevant industry-specific qualifications from major bodies like Chartered Accountants ANZ, which supports over 140,000 members
• certifications and years of experience

Timeline

If you're pitching for a specific project, outline clearly and realistically how and when you'll complete each part of it. Present this in a flowchart or a road map with deadlines and step-by-step actions.

If your proposal isn't for a specific project, give an idea of general timeframes your business works to, for example manufacturing or shipping times, or turnaround times for services.

Pricing, billing and legal

Pricing is often the section clients turn to first. How you structure it depends on the size of your project and the type of proposal.

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

Consider offering pricing options to give clients flexibility. If you're responding to an RFP, check the terms to ensure your pricing format meets their requirements.

Include any permits or licences required for the project. For example, registered companies in New Zealand must file an annual return and pay a fee of $49.74 plus GST to confirm their details on the Companies Register.

Terms and conditions

Clarify the terms and conditions that will govern the project. This section protects both you and your client by setting clear expectations.

Include items such as:

• payment schedules and deposit requirements
• cancellation policies
• warranties and guarantees
• delivery or shipping terms

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

Acceptance

The final step is to leave a space for signatures. Include a signature box for your client to sign when they accept your proposal. Make sure you include contact information if your client needs to follow up with any unanswered questions.

Business proposal tips

A solid structure gets you halfway there. These tips will help you stand out from competitors and increase your chances of winning the work.

Start with an outline

Before you begin writing your proposal, plan out everything in an outline. Ensure you have all of the key information you need and research any you don't have.

Include measurable data

Numbers build credibility. Use specific statistics, case studies, and performance metrics to prove the value you provide.

Present data through:

• Charts and graphs: Make complex information easily digestible
• Comparison visuals: Show how your solution outperforms alternatives
• Success metrics: Quantify results from previous similar projects

Use strategic visuals

Help readers understand with relevant visual elements:

• Use process diagrams to illustrate your methodology step by step
• Add timeline graphics to show project phases and key milestones
• Include before and after comparisons to demonstrate potential results
• Feature team photos to build a personal connection and trust

Incorporate video

If your proposal is online or a PDF, a short video can help strengthen your proposal and keep the prospective client interested. Types of videos that work include:

• Introduce your proposal
• Share testimonials

FAQs on business proposals

Here are answers to common questions about writing effective business proposals.

How long should a business proposal be?

The length depends on the project complexity and client requirements. A simple proposal might be 3-5 pages, while complex projects could need 20+ pages. Focus on being thorough rather than hitting a specific page count.

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

A quote simply lists prices for specific products or services. A proposal is comprehensive and includes the problem you're solving, your methodology, timeline, qualifications, and pricing. Proposals are persuasive documents that explain why the client should choose you.

Should I include pricing in every proposal?

Yes, include pricing unless the RFP specifically requests it separately. Clients expect to see costs before making a decision. If the project scope isn't fully defined, provide a price range or estimate with clear assumptions.

How soon should I follow up after sending a proposal?

Follow up within one week of sending your proposal. Send a brief email asking if they have questions or need clarification. This shows you're proactive and keeps your proposal visible.

Can I reuse the same proposal for different clients?

No. Customise each proposal to the specific client and their unique needs. Generic proposals show you haven't invested time in understanding their situation, which reduces your chances of winning the work.
