What a proposal is (and what it isn't)

A proposal is a written summary of the deal you and the prospect discussed: the problem, what you'll do about it, what it costs, and how to start. It turns a good conversation into something a buyer can approve, often by forwarding it to the person who controls the budget.

It isn't a sales pitch. If the prospect wasn't convinced on the call, a longer document won't change that; a second conversation might.

It isn't your agency's brochure either. Team bios, your history, methodology diagrams and case studies are supporting material. They belong on a web page you can link to, not between the buyer and the price.

And it isn't the contract. A proposal says yes in principle. Legal terms, liability and payment details belong in your agreement, which you send once the proposal is approved. Keeping the two separate means the decision-maker reads one page instead of twelve, and your lawyer's wording doesn't slow down a yes.

The five sections

A buyer needs four answers fast: did they understand my problem, what will I get, what does it cost, and what do I do to start. The five sections answer them.

Section	What it says	Common mistake
1. The situation	The problem in the client's own words, in two or three sentences	Rewriting it in agency jargon ("suboptimal engagement")
2. The outcome	What will be different in 90 days: work, cadence, what you'll measure	Promising results you can't control
3. What's included	Deliverables with quantities, plus one "not included" line	Leaving scope open to interpretation
4. Price and terms	One number or up to three options, billing rhythm, minimum term, notice, setup fee shown separately	Burying the price on page 11
5. Next step	One action with a date	Ending with "let me know what you think"

For the outcome, be concrete and honest: "Three posts a week on Instagram and LinkedIn, approved by you in one weekly batch" beats "elevate your brand presence." Promise the work and the cadence, and say what you'll measure.

The template

Copy this into a doc and fill in the brackets. Keep it to one page at a normal font size; if it spills over, cut words rather than shrinking the type.

PROPOSAL FOR [CLIENT NAME] — [DATE]

THE SITUATION
[Two or three sentences in the client's own words. What's
not working, and why it matters to them now.]

WHAT WILL BE DIFFERENT IN 90 DAYS
[One to three concrete outcomes. What you'll deliver, how often,
and what you'll measure.]

WHAT'S INCLUDED
- [Deliverable + quantity, e.g. 12 social posts a month across 2 platforms]
- [Deliverable + quantity]
- [Deliverable + quantity]
- Monthly report and a 30-minute review call

NOT INCLUDED
[e.g. Paid ads management, photo shoots, website changes. Available
separately if needed.]

INVESTMENT
[$X per month], billed [monthly in advance].
[3]-month minimum, then month-to-month with [30] days' notice.
[One-time setup: $Y, covers onboarding and the first month's plan.]

NEXT STEP
Reply "approved" by [date]. We'll send the agreement and
onboarding form the same day and start on [date].

[Your name] · [Agency] · [email] · [phone]
Case studies: [link] · References on request

If you offer options, replace the Investment block with a three-row table (for example, Essentials, Standard, Full Service) and mark the one you recommend. Three options give the buyer a choice of which, not whether.

How to send it

• Send it fast. The same day as the call is best, while the conversation is fresh.
• Put the summary in the email body. Many buyers read on their phone and won't open an attachment until they're at a desk. Paste the Situation, Investment and Next step sections into the email and attach the full page.
• Name a date. "I've held the 2nd as a start date; can you confirm by Friday?" gives them something to respond to.
• Follow up once, with something useful. If you hear nothing in three business days, send a short note that adds value, such as an idea for their first month. Then follow your normal follow-up sequence.

Common objections

"Clients expect a big document." Larger companies with procurement teams sometimes do. Send the one-pager first to get agreement, then provide the longer document their process requires.

"I need to show my value." You showed it on the call. If you didn't, a second call will help more than a longer document.

"What about legal terms?" Keep them in your agreement, not the proposal. If you're not sure whether an emailed approval is enough to start work where you are, ask a lawyer once and build the answer into your process.

Steps you can take today

1. Open your last three proposals and find where the price appears. If it's not on the first page, move it there.
2. Copy the template above into your proposal tool or a doc and fill it in for a current prospect.
3. Rewrite your "Situation" section using the exact words the client used on the call. Check your call notes.
4. Add a "Not included" line to every proposal you send from now on.
5. End every proposal with one next step and a date.
6. Move your case studies and team bios to a single web page, and link to it instead of attaching them.

FAQ

How long should an agency proposal be?

One page is enough for most agency proposals, because the decision was largely made on the call. Put supporting material like case studies and team bios on a web page and link to it.

What should an agency proposal include?

The client's problem in their own words, the outcome you'll work toward, a list of deliverables with what's not included, the price and terms, and one next step with a date. Everything else is optional supporting material.

Where should the price go in a proposal?

On the first page, stated plainly with the billing rhythm, minimum term and notice period. Buyers look for the price first, and making them search for it creates doubt.

How many pricing options should I offer?

One price or three options. Three options, with the recommended one marked, let the buyer choose which package rather than whether to buy.

How soon should I send a proposal after a discovery call?

The same day if you can. The conversation is fresh for both of you, and a fast proposal shows how you'll work once they're a client.

What should I do if a prospect doesn't reply to my proposal?

After three business days, send one short follow-up that adds something useful, such as an idea for their first month. Then move them into your normal follow-up sequence rather than chasing daily.

Do I need a separate contract if I send a one-page proposal?

Yes. The proposal confirms the deal in principle; the agreement covers legal terms, liability and payment details. Send the agreement as soon as the proposal is approved.
