How to Write a Business Proposal: Structure, Template and Follow-Up

If you sell services, knowing how to write a business proposal is one of the skills closest to your revenue. The proposal is the document a buyer forwards to the person who signs, reads twice, and compares with two others. This guide is written for the owner of an agency, a consultancy or a contractor business. It covers what to find out before you write, the sections a proposal needs and the order they go in, a template you can copy, the pricing page, and the follow-up between "sent" and "signed".

What a business proposal is, and what it is not

A business proposal is a written offer to do specific work for a specific client at a specific price. It names the problem, the work, the result, the cost and the terms, and it asks for a decision.

Three documents get confused with it:

• A quote or estimate lists a price for a defined item. It assumes the buyer already knows what they need. A proposal argues for the scope as well as the price.
• A business plan describes your company to investors or lenders. A proposal describes one engagement to one buyer.
• A contract is the binding agreement. Many proposals turn into contracts when signed, but if the work is large or regulated, the proposal is usually followed by a separate agreement your lawyer has reviewed.

Proposals come in two kinds. A solicited proposal answers a request: the client sent a brief, an RFP or simply asked "can you send me something?". An unsolicited proposal goes to someone who did not ask. Solicited proposals start with an advantage, because the buyer already has a budget and a problem they have admitted to. Most service businesses should spend their writing time there.

Before you write: the discovery call

A proposal written without a conversation is a brochure with a price on it. Before you open a document, get answers to five questions, ideally on a call:

1. What is the problem, in the client's words? Write down their phrasing. You will quote it back in the first section.
2. What happens if nothing changes? This is the cost of doing nothing, and it is what your price is compared against.
3. What does success look like, and how will they measure it? A number, a date, a launched thing, a passed audit.
4. Who decides, and who else reads the proposal? The person on the call is often not the person who signs.
5. What budget range and timeline are they working with? If they will not say, ask whether they expect a project in the range of X or of Y. Their reaction tells you enough.

If you cannot get these answers, say so in the proposal and propose a paid discovery phase instead of guessing at a full scope.

The structure: nine sections in order

The order below follows the buyer's questions in sequence: whether you understood the problem, whether you can do the work, what it costs and what happens next.

1. Cover page

Client name, project name, your company, the date, and the name of the person who will be the client's contact. Keep it plain.

2. Executive summary

Half a page at most. State the client's problem in their words, what you propose to do, the result they get and the total price. Write it as if the decision-maker reads only this page and the price, so it has to stand alone.

3. The problem and what it costs

Show that you listened. Describe the current situation, what it costs them in money, time or risk, and why now. Use their numbers, not industry averages you cannot back up.

4. Proposed solution and approach

What you will do, in phases, and why this approach rather than the obvious alternatives. If you considered a cheaper path and rejected it, say why. That paragraph answers the question the buyer was going to ask anyway.

5. Scope and deliverables

A list of exactly what the client gets, and a second list of what is not included. The "not included" list prevents most scope disputes. Name revisions, meetings, reports and handover materials explicitly.

6. Timeline

Phases with dates or durations, the client's own tasks (approvals, access, content), and what happens to the schedule if those tasks are late.

7. Pricing

The total, how it breaks down, and when it is paid. See the pricing section below for the formats that work.

8. Why you

Relevant experience, one or two short case studies with results, and the people who will actually do the work. Keep it about this project. Your founding story belongs on the website.

9. Terms and next step

Validity date of the offer, payment terms, what happens on acceptance, and one clear action: sign here, reply to confirm, or book a call.

How to write each section well

A template gives you the order. These habits decide whether the text inside it works.

Write the summary last. You only know what the proposal says once the rest is written. Then compress it.

Mirror the client's language. If they said "our leads go cold", write "leads go cold", not "suboptimal lead-nurturing velocity". A buyer who recognises their own sentence keeps reading.

Put numbers where claims would go. "We will improve response times" is a claim. "Replies within one business day, measured in your help desk" is a commitment the client can check. Only promise what you can measure and deliver.

One idea per paragraph, short sentences. Your proposal will be read on a phone between meetings. Headings, short lists and white space let a skimming reader find the price and the scope.

Name the risks. If the project depends on the client's IT team or on content they have not written, say so and say what you will do about it.

Cut everything generic. If a sentence would be true in any proposal to any client ("we are passionate about quality"), delete it.

Pricing the proposal

How you present the price changes how it is judged. Three formats work for service businesses:

• Fixed price per project or phase. Best when the scope is clear. The client knows the total; you carry the risk of overruns, so your scope section has to be precise.
• Time and materials with an estimate. Best when the scope will change. Give an hourly or daily rate, an estimated range, and a cap or a checkpoint where you ask for approval before exceeding it.
• Retainer. A monthly fee for a defined capacity or set of outcomes. Say what happens to unused hours.

Offering two or three options with different scopes, rather than one take-it-or-leave-it number, changes the buyer's question from "yes or no" to "which one". Make the middle option the one you recommend and explain why. Keep the options genuinely different in scope; three prices for the same work look like a trick.

Always state what the price excludes (taxes, travel, licences, third-party costs) and how long it is valid. A validity date protects you when your costs change and gives the client a reason to decide.

Mistakes that lose proposals

• Sending before the call. A proposal that guesses at the problem shows the client you did not ask.
• Leading with your company. The first page is about the client. Your history goes near the end.
• A scope with no edges. "Website redesign" without a list of pages, revisions and exclusions invites a dispute three weeks in.
• Burying the price. Buyers look for it first. If they have to hunt, they assume you are hiding it.
• No validity date and no next step. The proposal sits in an inbox with nothing asking for a decision.
• One version for everyone. Swapping the client's name in a generic document is visible within a paragraph.

After you send: follow-up and signature

Many lost proposals simply stall: the client meant to review it, the decision-maker was travelling, a colleague raised a question nobody answered. A follow-up plan fixes most of that:

• Send it in a short meeting where you can, or call within a day of emailing it. Walk the decision-maker through the summary and the price, and hear objections while you can still answer them.
• Agree a decision date on that call. "When will you be able to decide?" is a fair question once they have read the document.
• Follow up on a schedule you decided in advance, not when you remember. Each follow-up should add something: an answer to a question, a revised option, a relevant example.
• Close the loop. If the answer is no, ask why. The reason tells you what to change in the next proposal.

Make signing easy. In the United States, the federal ESIGN Act says a signature or contract "may not be denied legal effect, validity, or enforceability solely because it is in electronic form" (15 U.S.C. § 7001). For most service engagements a typed name and acceptance by email or an e-signature tool is enough; check with your lawyer for regulated work or large contracts.

Once you send more than a few proposals a month, a spreadsheet stops showing which one was opened, who owes the next answer and when to follow up, and deals stall without anyone noticing. inite.services is built for this: a CRM for service businesses with AI agents that carries a deal from the first lead message to a signed proposal and an automated follow-up.

FAQ

What are the main parts of a business proposal?

The core parts are an executive summary, the client's problem, your proposed solution, scope and deliverables, timeline, pricing, why you, and terms with a next step. Short proposals often merge these into five: summary, problem, solution, price, next step.

What are the three C's of proposal writing?

There is no single official list. Guides most often use clear, concise and compelling: clear about scope and price, concise enough to read on a phone, compelling because it is about the client's problem and result.

Can ChatGPT write a business proposal?

An AI assistant can draft structure, tighten wording and produce a first version of standard sections. It cannot know what your client said on the discovery call, what you will actually deliver or what you can afford to charge. Use it for the draft, then rewrite the problem, scope and price yourself and check every claim.

How long should a business proposal be?

As long as the decision needs. A small, well-understood job can fit on two pages; a multi-phase project may need ten. What matters is that the summary and the price can be found within the first minute.

How do I write a business proposal for a new client with no case studies?

Replace case studies with specifics: a detailed approach, a sample deliverable, a short paid pilot phase, or a guarantee on a measurable result. A narrow, precise scope earns more trust than a long list of capabilities.
