Writing quotes with AI without giving away your margin

An AI that guesses your prices will cost you margin. Here is how to have quotes drafted from your own price list and rules, with every line explained and nothing sent until you approve.

Quoting is where a small business makes or loses its margin. It is also the job that gets pushed to nine at night. So it is a natural thing to hand to AI, and a risky one. A tool that does not know your prices will fill the gap with plausible ones. Plausible is not the same as profitable.

The fix is not a smarter model. It is a quote that is built from your numbers and your rules. Here is how that works with the Quoting agent in Brainztem, and what you need to give it first.

Where margin leaks in an AI quote

  • Invented prices. The tool has no price list, so it estimates.
  • Missing lines. The things you always charge for and a newcomer forgets: delivery, disposal, site conditions, the small panel that takes half a day.
  • No floor. Nothing tells the tool there is work you decline below a certain margin.
  • Stale numbers. A quote from three months ago goes out again after material costs have moved.
  • Verbal changes. The customer adds something on the phone and it never reaches the paperwork.

Every one of these is a knowledge problem. The tool was never told.

Put your prices and rules in the brain

The Quoting agent prices from your brain, the plain pages your crew reads. Two kinds of page do most of the work.

The first is your price list. Add it as it is: a PDF, a spreadsheet, or a photo of the laminated sheet on the shop wall. Your crew reads it and files it as a knowledge page.

The second is your estimating rules. This is the page many businesses have never written down, because the rules live in the owner's head. It can be short. What your rate covers. What is always priced as its own line. The minimum you will take a job for. When a quote expires. How change orders are handled.

Correct the estimating page once

The first quote your crew drafts will show you what is missing. That is useful. Say it left out a line you always include. Do not only fix that one quote. Open the estimating page, press Edit page, add the rule and save.

From then on your crew reads the page the way you wrote it. The correction also shows on the Brain tab as a receipt, so you can see that it took. Fixing the quote helps one customer. Fixing the page helps every quote after it.

Here is a made-up example. A twelve-person cabinet shop finds that old quotes keep being accepted after oak prices have moved. The owner adds one rule to the estimating page: re-quote anything older than 30 days that has not taken a deposit. One sentence, written once.

What the Quoting agent does with a request

Paste the customer's email or your call notes into chat and ask for a quote. The agent pulls the scope from the request and prices it from the prices, materials and rules in your brain. It shows its working on every line, so you can see how each number was reached and adjust it. The result is an itemized quote as a PDF.

Then it stops. Nothing goes to the customer until you send it.

Read it like an owner

Reviewing a drafted quote is less work than writing one, and it is still your job. Check four things before it goes out. The scope matches what the customer asked for. Every line you always charge for is there. The total clears your floor. The expiry date is stated.

If a number looks wrong, read the working on that line. A wrong number usually traces back to a missing or outdated page, and the page is where to make the fix.

What it costs and what it will not do

The Quoting agent is $19, $29 or $49 a month depending on the level, on top of the $99 a month workspace. At the Steady level that includes about 30 quotes a month.

It will not measure the site, judge a difficult customer, or decide to take a job at a loss to win a client. It does not know a supplier raised prices unless a page says so. Those calls stay with you.

Start with one page. In your workspace, open the Brain tab, add your price list, and write five lines of estimating rules. Then ask for a quote on a real request. No workspace yet? Start the free 48-hour preview at brainztem.com.

Frequently asked questions

Can AI write accurate quotes for a small business?

It can draft them accurately when it prices from your own numbers. The Quoting agent uses the prices and rules in your brain and shows its working on every line.

How do I stop AI from underpricing my work?

Give it your price list and write your estimating rules as a page: what is priced separately, your minimum, when a quote expires. Then read every quote before it goes out.

Does the quote go to the customer automatically?

No. The quote is a draft PDF for you to review. Nothing goes to a customer until you send it.

What does the Quoting agent cost?

$19, $29 or $49 a month depending on the level, added to the $99 a month workspace.
