What Is a Proposal Letter?

A business proposal refers to a formal document that department heads, executives, or clients request for anyone to pitch a plan or idea into action later on. Meanwhile, a proposal letter is where you officially write the proposal’s details as an introduction. Hence, this official letter introduces the plans, ideas, or business data while the recipient decides whether to push through with the plan, come up with some changes, or wholly reject it.

According to Inc. Magazine, the elements of a business proposal are the title page, table of contents, executive summary, statement of the problem, approach, methodology, bidder’s qualifications, schedule or timeline, and the cost proposal.

Why Is a Proposal Letter Important?

A proposal letter is essential since it marks the initial impression observed by your recipient regarding your brand, your business, or you. Thus, the letter’s content is responsible for how the recipient either praises your project proposal and pushes through with the plan or how it does not go according to your favor. So before getting into the specifics or a highly detailed proposal, proposal letters are introduced.

Also, proposal letters work for eclectic purposes. Besides a general business project, you can use proposal letters for loan requests, government grants, service trackers, marriage proposal plans, product redesigns, emergency funding, and even marketing plans. So from a small project down to a large-scale event, proposal letters can introduce all types of examples. Just make sure to specify the necessary data in the letter to achieve your purpose.

The Standard Parts of a Proposal Letter

Speaking of specifying the needed data in the proposal letter, do you know what to include inside the letter in the first place? As Inc. Magazine reported, business proposals contain the title page, table of contents, executive summary, problem statement, methodology, approach, bidder’s qualifications, timeline or schedule, and the cost proposal. However, proposal letters are much shorter so you need not add all parts. The elements you should be concerned about for proposal letters are only the following:

Subject Title: Always add a specific title to the document you use as your proposal letter. This makes it simpler to understand what the document’s intent is for. The easy way to do that is by typing “Proposal Letter” at the top center part of the document. Write it in capital and bold letters for visibility too.Date: You cannot forget about the complete schedule or date regarding when you wrote the letter. Simply write down the day, month, and year of when you created it. This part helps recipients review how long the letter was made if it was proposed just recently or very late.Sender and Receiver Details: Whoever writes the letter should put her/his/their name as the sender in the sender details. Simply jot down your name, contact list, and address. Acknowledge your letter’s recipient under the receiver’s data as well. Whether you are talking to a manager, client, or anyone, always write their name, address, and contact details in the letter.Salutation: In any letter, insert a proper salutation as a way of addressing to whom it may concern. You can just use “Dear” followed by the appropriate pronoun and name in writing this.Introduction: The introductory statement is where you should begin impressing your recipient. So state who you are and what your proposal aims to achieve. This part is where you may summarize the name of your company, the main concern of the letter, and other relevant details. What matters the most is that recipients get the gist of your message right from the introduction.Body: Expound your introduction by heading to the specifics right in the body of your letter. This section of your message answers the most significant questions from what the proposal involves, the timeline of activities, the budget plans, the benefits of the program, the executive summary, and so much more.Complimentary Close: When you are through with the body, you add a closing statement until you can insert the complimentary close. This is where you can end the message formally, like “Sincerely yours.”Signature: What follows the complimentary close would be the signature line. Affixing signatures is a proper way of ending a letter. And it confirms who sent the letter and that its details were already rectified since there is an official signature given.

Step 1: Research on the Client’s Industry, History, Competitors, Etc.

First things first, how well do you know your recipient? Whether you are proposing to a client, department head, executive, or any recipient, make sure you know your target’s industry, competitors, history, and other related data. Conduct a research or data analysis so that you get an idea of what your recipient needs or what their background is. This idea helps you know how to tailor your whole proposal that would matter or interest your recipient later on.

Step 3: Begin Inserting the Elements or Parts of a Proposal Letter

Can you still remember the standard parts of proposal letters? Apply what you learned by adding the subject title down to the signature line in your chosen proposal letter template, as discussed earlier. Those elements of a proposal letter will help organize your data so it becomes easy to read. More so, adding more parts is acceptable. That is if you have other relevant details worth discussing in your letter.

Step 4: Get to the Point in the Introduction, Purpose, and Goals

Grab attention immediately by getting to the gist of your whole proposal letter. And since the first few elements of a proposal letter contain the introduction, purpose, and goals, you have to think about the first impressions they give already. A tip is to be direct to the point and use simple language so you can expect the recipient to understand the message smoothly.

Step 5: Consider How Your Proposal Helps Your Client

In writing the letter, think about how helpful or relevant your proposal is for the client. At the end of the day, you are selling or pitching an idea to your recipient. So it should be interesting or useful to that client if you are expecting approval. A professional tip is to realize the client’s needs, weaknesses, and more. Next, create a cost/benefit chart so you will understand how beneficial your proposed project is and that its advantages are far greater than the cost involved. Oftentimes, strategic sales plans interest clients so prove that in your proposal.

Step 6: Highlight Why Your Client Should Choose You

You might have created a decent proposal but don’t forget the fact that your recipient could have numerous proposals to choose from. So if anyone can make a proposal, prove why your client must choose your proposal instead. To do that, you can highlight how your plans can really meet your recipient’s needs and standards. Or perhaps, you expound thoroughly on how your own proposal stands out from other competitors. You can show portfolios of your best previous works and feedback from satisfied clients before perhaps.

Step 7: Don’t Forget the Call-to-Action Statement

Standard tips include formatting your proposal letter, ensuring that enough data is presented in a one-page document, adding visuals to lessen wordy texts, and remaining straightforward with your words so it won’t be a long letter. And after that, ensure that you have inserted a proper call-to-action statement. This statement is where you request the recipient to respond to the letter as soon as possible. Encouraging a response is recommended or the letter might just be read and ignored. Also, you can provide options in asking an answer from accepting the terms of the proposal or discussing it further if the recipient wants some changes. At least you are not just giving away an option for the recipient to reject the entire offer.

Step 8: Insert Supporting Documents and Background Details

Last but not least, insert supporting documents and other necessary details to support your proposal before wrapping it up. This documentation would include your work portfolio, sales records, or business forms that recipients must fill out. And once you find no error in your proposal letter, it is ready for submission. Send it to your recipient now!
