Advice about templates tends to arrive in two flavours, both of them wrong. One says never use one, which ignores that you are writing twenty of these a week. The other offers a template to copy, which produces the exact problem it claims to solve.
The useful distinction is between structure and voice, and only one of them is safe to reuse.
Structure is invisible
A client cannot detect that your proposals follow the same four-part shape. Shape is not what they recognise, and having one is what lets you write a good proposal in six minutes instead of twenty-five.
Reuse the structure aggressively. Reuse the paragraph about how you work. Reuse the way you present your relevant piece of work. None of that is what gives a template away.
Voice is extremely visible
What the client recognises is the opening, because they have read it forty times this week in other people's words. "I have carefully read your job description" is a template signature. So is any sentence that begins by describing you.
The popular templates are the worst ones
A template that circulates widely is, by definition, the one the client has seen most. Its popularity is precisely what makes it fail, and that gets worse the better it is.
The rule
Write the first two lines from scratch every single time. Reuse everything under them.
That is the whole discipline. It costs two or three minutes per proposal and it is the difference between a proposal that gets opened and one that does not.
Before
[Opening] Hi! I read your job post and I'm confident I can help. [Approach] I'd start by auditing what you have... [Proof] I did something similar for a client last year... [Question] What's your timeline?
After
[Opening] Written fresh for this job, about their specific situation. [Approach] I'd start by auditing what you have... [Proof] I did something similar for a client last year... [Question] What's your timeline?
Everything after the opening is identical. That is fine. That is the point.
What to keep in the reusable half
- How you work. Your process, communication rhythm, how you handle scope changes. This does not change per client and it reassures every one of them.
- Two or three proof paragraphs, each about a different kind of job, so you can drop in whichever is closest.
- Your availability and your terms. Same every time, and worth saying every time.
What never goes in the reusable half is the opening, the question at the end, and anything that pretends to be specific while being generic. Clients can tell, and a fake specific is worse than an honest generic.
The four-part shape itself, and why each part is where it is, is in proposals that get replies.
