What is a business proposal letter?

Business proposal letters are an official way of introducing an organization, product, or service to clients, partners, or investors. This brief document informs your target audience about your business and offers a problem-solution proposition. The letter will create a desire in the client to go through your proposal when receiving it. Smart companies use proposal letters to sell their unique selling point and stand out from their competitors.

It can even serve as a proposal itself, where there is no need for a lengthy proposal. While it is usually shorter, it still follows the same structure as the entire proposal.

When do you use proposal letters?

Proposal letters are suitable for a variety of situations:

  • Small Business Projects: A proposal letter can also be useful when providing services, such as website design, marketing, or consulting services, to business entities or individuals. Briefly describe the proposed project and its costs.
  • Sales Proposals: When launching a new product or service to prospective consumers, the proposal letter may create interest and ensure the buyer knows the product details and services.
  • Grant Applications: It is common for organizations and foundations to have a preliminary letter, usually a letter of inquiry or a proposal letter. This letter indicates your project, its applications, and the grant you want to apply for.
  • Partnership Opportunities: A proposal letter for partnership opportunities can be written when you are searching for partners or joint ventures since it presents the company’s information while promoting the possible advantages of partnership.

Proposal letters are crucial in closing deals faster as it works as a presursor to the original proposal.

How to write a business proposal letter

When writing a compelling proposal, it’s important to stay organized and focus on your priorities. Here’s a simple guide to help you write a proposal letter that clearly shows your value:

Introduce yourself and provide background information

To write any type of business letter, start with an appropriate greeting, “Dear [Recipient’s Name],” then an introduction containing information about you and your business organization. If you have already interacted with the client before, mention about the meeting briefly. 

Then, move on to providing an overview of the topic, your company’s main specialization, and some testimonials or case studies similar to the client’s industry or needs. 

Bad example: “To whom it may concern,

We are ABC Marketing, and we offer various marketing services…”

Good example: “Dear Ms. Davis,

My name is John Smith, and I’m the Business Development Manager at XYZ, a leading digital marketing solutions company for small businesses like yours.”

State the problem statement and the purpose of the proposal

When you are writing a proposal letter, make sure to add in parts of your proposal or highlight a few paragraphs that focus on the problem statement. The purpose of your proposal letter is to summarize your client’s pain points and explain how you can help them with unique ideas. 

Make sure that your business proposal clearly outlines all the details of the arrangement, such as the client’s pain points and how you can help them.

For example, if you are proposing to redesign a company website, explain the current issues with their site and how your redesign will improve user experience and functionality. 

Bad example: “We can help you with your website redesigning needs.”

Good example: “We have noticed that your current website is outdated, leading to a poor user experience. Visitors find it difficult to navigate, which results in high bounce rates and lost sales opportunities. Our proposal aims to redesign your website to enhance user experience and increase website traffic by 10X.”

Define your goals and objectives

Explain the long-term goals you want to achieve and the specific objectives you will set to reach them. Be clear and include specific numbers or percentages if you can.

Bad example: “We will improve your online presence.”

Good example: “Our first objective is to ensure that your website traffic improves by 30% in the next six months. To help you with this, we will start with a comprehensive SEO content audit that I am confident will enhance your site’s ranking and unique and catchy e-mailing campaigns with an open rate of 15% and click-through rate of 5%.”

Evaluation

Explain how you will keep track and assess the progress of your proposed solution. List the ways you will measure success and how you will share these results with the client. This shows your commitment towards building a transparent relationship with your client.

Good example: “We will provide weekly reports on website traffic, lead generation, and social media engagement. We will also conduct meetings to assess progress and make any necessary adjustments to our workflow to meet your goals.”

Highlight what sets you apart

If your proposal solves a company’s problem, showing off your special skills can help you stand out. Mention your unique abilities related to the project and explain why you are the best choice for the job. If your proposal is for a business idea, highlight what makes your ideas different from others. Use bullet points to list your key features, making them easier to read.

Bad example: “We are the best event management firm in the area.”

Good example: Our Event Management Proposal template explains how you can set yourself apart from your competitors. “With over 5 years of experience in event planning, we have transformed countless ideas into unforgettable experiences for our clients. 

When events aren’t well-organized, guests may not enjoy themselves, leading to fewer attendees and lost revenue for your organization. Our team of experts makes sure to turn the simplest idea into a fantastic event that your guests will remember. forever”

Briefly Discuss the Budget

Depending on why you are writing the proposal letter, you may need to explain how you will utilize the client’s budget. You don’t need to list every expense, but giving a general budget idea will help your clients understand the project better.

Good example: “We have estimated the total cost of our proposed digital marketing strategy to be $X, with a projected ROI of Y% within [timeline].”

Write a Strong Closing Paragraph and provide contact information

End the proposal letter by stating that you are happy to answer any questions related to the project or provide additional information if necessary. Add your contact details and encourage the client to get a follow-up call.

Good example: “We will be looking forward to working with you and contributing towards the success of your business. Please don’t hesitate to contact me at [your email/phone number] to discuss this proposal further. We look forward to hearing from you soon.”

Key tips while writing a proposal letter

To make sure that your proposal letter stands out, keep these tips in mind:

  • Know Your Goals: Ask these questions before writing your proposal letter. Who are you writing/marketing to? Which action plan or ideas will benefit the client? Are there any particular rules or regulations that you have to observe strictly?
  • Format and Formality: Look at how your proposal is situated. Is it a formal bid for a large company or an informal one for a small business? Choose a format that aligns with the target audience and scale of the project.
  • Visual Appeal: Use a neat, professional font with consistent spacing, and include headers or bullet points to help with readability.
  • Proofread thoroughly: Proofread for grammar, spelling, or formatting errors before sending your proposal letter. A well-written, professional proposal creates a lasting impression in the client’s mind.
  • Streamline the process with proposal software: If writing a well-crafted proposal seems overwhelming, then proposal management software, like Super Proposal, can help you.
