Proposal Letter
A proposal letter is the short, one-to-two-page version of a proposal — used to open a conversation, accompany a full proposal, or make a simple offer where a full document would be overkill. Here is the structure, and how to tell which format the situation needs.
A proposal letter is a short letter that proposes work, typically one to two pages. It is used in three situations: as a cover letter accompanying a full proposal, as a standalone offer where the work is simple enough that a full document would be disproportionate, and as an opening approach to a prospect who has not yet asked for anything. It follows the same logic as a full proposal — their problem, your approach, what it costs, what happens next — compressed into prose rather than sections. The structure below is the standard form. Where a letter is not enough, Gixo Arc drafts the full document from the same source material.
What a proposal letter contains
Six moves, in order, in prose rather than headed sections. The whole thing should fit on one page unless the work is genuinely complex.
What wins and what loses
| What wins | What loses |
|---|---|
| Names the price or the range | Defers all commercials to a later conversation |
| Fits on one page | Runs to four pages and becomes a bad proposal |
| One specific comparable engagement | General claims of experience |
| A single, dated next step | An open invitation to get in touch |
| Opens on why you are writing | Opens on pleasantries |
When a letter is not the right format
Use a full proposal when the scope needs a boundary, when pricing has components, or when more than one person will review it. A letter cannot carry an exclusions list or a phased budget, and stretching it to try is how you end up with a document that is too long to be a letter and too thin to be a proposal. Gixo Arc drafts either from the same source material, so the decision does not cost you the work already done.
Proposal letter: FAQ
How long should a proposal letter be?
One page. Two if the work genuinely needs it. Past that the format is wrong and you should be sending a proposal with a short cover letter instead.
Is a proposal letter the same as a cover letter?
A cover letter introduces an attached document. A proposal letter can do that, but it can also stand alone as the offer itself. The difference is whether there is anything attached.
Should a proposal letter include pricing?
Usually yes, at least as a range. The reader is thinking about it regardless, and omitting it tends to add an exchange rather than avoid a difficult conversation.
Do I send a proposal letter by email or as an attachment?
In the body of the email, in most cases. An attachment adds a click before your first sentence is read, and a one-page letter does not need to be a PDF unless it is going into a formal process.
