Use it when
You sent an estimate and the customer asks why it costs that much or what a line is for.
The instruction
Copy it into ChatGPT, Claude, Gemini or Copilot and fill in the [brackets]. The rules at the end are what stop it from guessing.
Help me explain an approved estimate in plain words. Explain what each line is for. Do not change any number. Only give reasons I list below. Estimate lines: [paste them] Customer's question: [paste it] Reasons I can stand behind: [code, permit, safety, manufacturer, your own reasons] Rules: use only the facts I give you and my business fact sheet if I shared it. Do not invent prices, warranty terms, diagnoses, code requirements, dates or promises. Mark anything I did not confirm with [brackets] and list it under the draft. Keep it short and friendly, like a local business owner wrote it. Write the draft first, then ask me at most one question.
Worked example
What you paste
Estimate lines: 1) Remove and dispose existing 40 gal gas water heater. 2) Install 50 gal gas water heater, new flex gas line, new expansion tank. 3) Permit and inspection. 4) Seismic straps to code. Total $3,480. Customer's question: why do I need an expansion tank and a permit? the old one didn't have either
Real reply from Gemini, September 21, 2026
Here is a breakdown of what each line item covers and why it is part of the estimate: Remove and dispose existing 40 gal gas water heater: Covers taking out the old unit, hauling it away, and properly disposing of it. Install 50 gal gas water heater, new flex gas line, new expansion tank: Covers setting up the new 50-gallon tank, along with a new flexible gas supply line and an expansion tank for safety. Permit and inspection: Pays for the official city/local permit fee and the required city safety inspection to ensure everything is installed safely to code. Seismic straps to code: Secures the water heater to the wall framing to prevent it from tipping over during an earthquake. Why you need an expansion tank and permit now: Building and plumbing codes have updated over time. When water heats up, it expands. An expansion tank gives that expanding water a safe place to go so pressure doesn't build up inside your pipes or new water heater. Even if your old system didn't have one, current local plumbing codes require an expansion tank on closed water systems, as well as a permit and city inspection, to protect your home and ensure the work meets current safety standards. Total: $3,480
Run with an earlier version of this instruction, before the line asking for reasons you can stand behind. Shown as written, without its closing question.
Confirmed
- Every line and the $3,480 total
Check before sending
- The code claim. The owner never said the local code requires the tank. Gemini added it.
Check before you send
- Every number matches the estimate exactly.
- Any code or safety reason is one you gave it and can stand behind.
If something is off
Ask for one change and see the whole draft again.
Remove the sentence about local code. Our reason is that the new heater's manufacturer requires an expansion tank for the warranty when the home has a pressure regulator. Say that instead.
