Start with what your company is, who it's for and why it will succeed, in a few plain sentences. The SBA's business plan guidance says to include your mission statement, your product or service, and basic details on leadership, employees and location, adding financial information and high-level growth plans only if you're asking for financing. Then shape the rest around your reader's decision.
Before you write: who reads it, and what must they decide?
Think of the executive summary as the only page some readers will ever see. Plenty of decision-makers stop there, so before writing anything, settle one question: what do I want this person to do once they've finished it?
The clearest public guidance comes from the US Small Business Administration, which lists the executive summary first among the common sections of a traditional business plan. Its instruction is simple: briefly tell your reader what your company is and why it will be successful. That's written for business plans, not client sales proposals, so treat its section list as a guide. The SBA itself says plan formats aren't right or wrong; what counts is that yours meets your needs.
If you're replying to a formal request for proposals, the buyer has already told you what they want. US federal rules say an RFP must set out the information required in the offeror's proposal. Many private buyers do the same. Your summary should answer those points first, in their order, before anything you'd like to say.
Seven steps to a summary that stands on its own
- Write the body of the proposal first. It's a practical habit rather than an official rule, but you can't summarise what you haven't worked out yet.
- Name the reader's decision in one line on a sticky note: approve, shortlist, fund or book a call. Keep it in view while you write.
- Open with what your company does and for whom.
- State the problem or need in the reader's own words, taken from their brief, email or RFP.
- Make the case for why it'll work, drawing on the SBA's suggested details: mission statement, offer, team, employees, base. Choose only what this reader cares about.
- Say what outcome you're proposing, then add financial detail only if money is the decision (see the financing branch below).
- End by naming the next step you want taken.
If you're building the whole document from scratch, it helps to start from a proposal template designed to win the work so the summary and the body line up.
The fill-in outline to copy
Swap every bracket for your own facts.
| Line | What goes in | Your version |
|---|---|---|
| Sentence 1 | What [company] does and for whom | [We help ... to ...] |
| Sentence 2 | The reader's problem or need, in their own words | [You told us ...] |
| Sentences 3 and 4 | Your solution and why it will succeed: mission, product or service, leadership, employees, location | [Our approach is ... because ...] |
| Sentence 5 | The result or outcome you're proposing | [By the end, you'll have ...] |
| Only if asking for financing | One line each: funding needed, what it covers, high-level growth plans | [We're asking for ... to cover ... so that ...] |
| Final line | The decision you want the reader to make next | [The next step is ...] |
The check: read only the summary aloud to someone who hasn't seen the proposal. Can they say who you are, what you offer and what you want from them? If not, rewrite it before you touch anything else. For ready-made layouts, these free executive summary templates are a fair starting point, as long as you replace every generic line with your own facts.
The financing branch: when money is the decision
Here's the point most templates miss. The SBA says financial information and high-level growth plans belong in the executive summary if you plan to ask for financing. That word if matters. A summary for a lender looks different from a summary for a client choosing a supplier, because the reader is deciding something different.
When you are asking for funding, the SBA's guidance on the separate funding request section is to explain how much funding you'll need over the next five years and what you'll use it for. Its goal for financial projections is to convince the reader that the business is stable and will be a financial success. Your summary should give the headline of both, one line each, and point to the detail later in the document.
The SBA also notes that lenders and investors commonly ask for the detailed traditional plan, so expect your summary to be read alongside a full set of numbers. I'd get an accountant or financial adviser to check any figures before they go to a lender, and a solicitor or lawyer to look at anything that becomes a contract. This page isn't financial or legal advice.

How long should it be?
Nobody I could find puts an official word or page count on an executive summary, so treat any figure quoted as gospel with suspicion. For scale, the agency contrasts the traditional version, which can stretch to dozens of pages, with the lean startup format: usually a single sheet, quick enough to knock up in about an hour.
A useful comparison, though it's about a different document, comes from Purdue OWL's guidance on report abstracts. It describes an informational abstract as 10% or less of the report, written to let readers decide whether they want to read the rest. That's the job your summary does too: short enough to read in one go, complete enough to decide on.
What an executive summary can't do
- It can't rescue a weak proposal. It only reflects what the body proves.
- Where an RFP sets the format, the RFP wins.
- It isn't helped by financial detail the reader doesn't need. Keep money lines for when funding or cost is the decision.
- SBA guidance is for business plans; adapt it for sales.

Frequently asked questions
Should the executive summary be written first or last?
Last, in practice. The SBA doesn't instruct this, but it's hard to summarise a proposal you haven't finished. Write the body, then pull the summary from what it proves.
What's the most common executive summary mistake?
Copying a template's headings whether or not they help this particular reader. Projections and growth plans earn their place when you're asking a lender or investor for money; in a pitch to a client choosing a supplier they mostly get in the way.
Can I use the SBA business plan format for a client proposal?
You can borrow from it. Bear in mind the agency wrote it for business plans rather than pitches to buyers, so keep the pieces your reader will use and cut the rest without guilt.
How do I write the summary for an RFP response?
Mirror their brief. Take the list of must-have items from the request, answer each in the order given, and only then add anything extra you want them to know.
Is there a standard length for an executive summary?
No sourced word or page limit exists. As a sense of scale, the SBA says lean startup plans are typically one page, and Purdue OWL describes report abstracts as 10% or less of the report. Aim for something a reader can finish in one sitting.
