Quick answer. Paste the technician's notes and your priced lines, tell the AI to keep every finding and price exactly as written, and make it sort items into "recommended now" and "can wait" with a reason for each. Then check the numbers against your shop system. Before doing work beyond the estimate, send a short approval request and record the yes; the FTC tells drivers to expect that call, and some states require it.
Why a workflow beats a one-off prompt
A service writer's day is translation: "cat eff low, P0420" into something a driver will approve, then the same job back into an invoice that matches what was said at the counter. Most comebacks and bad reviews start with a surprise on the bill, not a bad repair. A workflow keeps the translation consistent, keeps the shop's numbers untouched, and puts the approval step in writing every time, even on a busy Saturday.
Each workflow has five parts: the job it does, a prompt template with [BRACKETS] to fill, an example input with the kind of output to expect, a check before you send (facts, numbers, names, tone), and a privacy rule. Every prompt ends by telling the AI to write [CHECK] instead of guessing, so missing facts show up instead of being invented.
Three workflows you can run today
1. Plain-English repair estimate from the tech's notes
Prompt template (replace every [BRACKET] with your facts):
You are a service writer at an independent auto repair shop. Turn the technician's notes below into a written estimate for the vehicle owner. Use only the facts given. Sections: (1) What you told us [CUSTOMER CONCERN IN THEIR WORDS]; (2) What we found, one plain sentence per item, no jargon without a short explanation; (3) Recommended now, with the reason (safety, prevents damage, or you asked for it); (4) Can wait, with the reason; (5) Parts and labor lines exactly as I give them; (6) Estimate total [TOTAL FROM MY SHOP SYSTEM]; (7) the line: "We will contact you for approval before doing any work beyond this estimate." Vehicle: [YEAR, MAKE, MODEL, MILEAGE]. Tech notes: [NOTES]. Parts and labor lines: [LINES WITH PRICES]. Do not add any repair, part, price or diagnosis that isn't in my notes, and do not use scare words. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: 2017 sedan, 84,200 miles. Concern: grinding when braking. Tech: front pads 2 mm, rotors scored below spec, rear pads 5 mm, brake fluid dark. Lines: front pads and rotors $412.80; brake fluid flush $129.00. Total $541.80 before tax.
What to expect: Expect a one-page estimate in plain words: "Front brake pads are worn to 2 mm; that grinding is metal on metal", front brakes under Recommended now (safety), rear pads at 5 mm under Can wait with "we'll measure again at your next oil change", the fluid flush listed with its reason, your two price lines and total copied exactly, and the approval line at the end.
Check before you send:
- Facts: every finding is in the tech's notes; nothing was upgraded from "can wait" to "needs it now".
- Numbers: each price, the total, tax note and mileage match your shop system to the cent.
- Names: year, make and model are right; part names match what you're ordering.
- Tone: plain and calm; no "dangerous" or "you're lucky you came in" unless the tech wrote it.
Privacy rule: Leave out the owner's name, phone, plate number and VIN. Use "the customer" and the year, make and model; add the rest in your shop system.
Rule to know: The FTC's Auto Repair Basics tells drivers to ask for a written estimate that identifies the condition to be repaired, the parts needed and the expected labor charge, and says the estimate should state that the shop will call for approval before work beyond a set amount; state law may require this. Check your state's auto repair rules. (FTC)
2. Additional-work approval text and phone script
Prompt template (replace every [BRACKET] with your facts):
Write two things for an auto repair shop that needs the vehicle owner's approval for added work. (1) A text message under 70 words: what we found [FINDING], why it matters [SAFETY / PREVENTS DAMAGE / COMFORT], the added cost [AMOUNT, INCLUDING TAX OR NOT], new estimated total [NEW TOTAL], new ready time [TIME], and "Reply YES to approve or call us at [SHOP PHONE]. We won't do this work without your OK." (2) A 30-second phone script with the same facts and one line for what happens if they say no [WHAT WE'LL DO INSTEAD]. Use only these facts, don't pressure, and don't say the car is unsafe to drive unless I wrote that. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: During the brake job the tech found a leaking front caliper. Added $186.40 plus tax; new total $728.20 plus tax; ready tomorrow 11 a.m. instead of today 5 p.m. If no: we finish pads and rotors and note the caliper.
What to expect: Expect a 60-word text that leads with the finding, gives the added amount and the new total, the new ready time and the YES/call line; and a short script that ends with "If you'd rather wait, we'll finish the pads and rotors today and note the caliper on your paperwork."
Check before you send:
- Facts: the finding is the tech's, in the tech's words; nothing was added for the upsell.
- Numbers: the added amount, new total and tax note agree with the revised estimate in your system.
- Names: shop phone number and the vehicle are right.
- Tone: informative, never "you have to"; the customer can say no.
Privacy rule: Don't paste the customer's name, phone or card details. Record the approval (who, when, how) in your shop system, not in the chat.
Rule to know: The FTC's Auto Repair Basics says the estimate should state that the shop will contact the customer for approval before doing work beyond a set amount, and that state law may require it. Write down when and how approval was given. (FTC)
3. Completed repair order explained for pickup
Prompt template (replace every [BRACKET] with your facts):
Write a pickup summary for a completed auto repair, to hand over or email with the invoice. Use only these facts: vehicle [YEAR, MAKE, MODEL]; odometer in [MILES] and out [MILES]; each repair done, with parts and their costs and the labor charge, exactly as on the repair order [LINES]; anything recommended but declined [ITEMS]; our warranty on this work [TERMS IN OUR WORDS]; old parts [KEPT FOR YOU / AVAILABLE ON REQUEST / CORE RETURN]; next service due [MILES OR DATE, FROM OUR NOTES]. Under 200 words, in plain English, with the total last. Don't add advice, parts or warranty terms I didn't give. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: Front pads and rotors $412.80, caliper $186.40, labor included per line; odometer in 84,212, out 84,219; rear pads declined; 12-month/12,000-mile parts and labor warranty; old parts in a box in the trunk; next oil change at 87,000.
What to expect: Expect a short list of the three repairs with their amounts, odometer readings, a Declined line for rear pads, the warranty in your exact words, "Your old parts are in a box in the trunk", the next service mileage and the total at the bottom.
Check before you send:
- Facts: every line is on the repair order; declined work is listed so there's a record.
- Numbers: amounts, total and odometer readings match the invoice.
- Names: part names and the vehicle are right.
- Tone: clear and thankful; warranty wording is yours, not the AI's.
Privacy rule: No VIN, plate, customer name or payment details in the chat; the invoice from your shop system carries those.
Rule to know: The FTC's Auto Repair Basics tells drivers to get a completed repair order listing each repair, the parts supplied and their costs, labor charges and the odometer readings in and out, and to ask for replaced parts; state law may require returning them. Check your state's rules. (FTC)

Rules to know before you post or send
The FTC's consumer guide Auto Repair Basics tells drivers to ask for a written estimate that identifies the condition to be repaired, the parts needed and the anticipated labor charge, and says the estimate should state that the shop will contact them for approval before doing work beyond a set amount; state law may require this (FTC Auto Repair Basics). It also tells drivers to get a completed repair order listing each repair, the parts supplied and their cost, labor charges and the odometer reading in and out, and to ask for replaced parts back. The three workflows above follow that list, so your paperwork matches what customers have been told to expect. Check your state's auto repair rules for estimate and authorization requirements.
On warranties, the FTC says it's illegal for a manufacturer or dealer to deny coverage simply because someone other than the dealer did the work; they can deny a repair only if they show the outside work or an aftermarket part caused it, and drivers should keep every service receipt (FTC warranty tips). The kit's warranty reply says that much and no more; it isn't legal advice. For reviews, the FTC's rule bars fake reviews and review suppression (FTC rule Q&A).
What stays out of the chat
Whatever the workflow, don't paste Social Security numbers, ITINs, driver's license or passport numbers, or photos of IDs; bank, card or loan account numbers and routing numbers; health information about a named person: diagnoses, medications, allergies, disability details; passwords and door, lockbox, alarm or gate codes; signed contracts, leases or applications with personal details still on them; anything a client told you in confidence. Use first names or roles, type only the facts a draft needs, and set your AI tool's chat history and training options to the most private choice it offers. The FTC's guide for businesses puts it as take stock, scale down, lock it, pitch it and plan ahead (FTC). If staff use AI tools too, the Small Business AI Use Policy Kit puts these rules in a written policy. The free AI tool risk check shows how much business data is going into AI tools now.

Common questions
Can an AI tool diagnose a car from my tech's notes?
No, and the workflows never ask it to. The diagnosis is your technician's. The AI only rewrites the findings in plain words and sorts them the way the tech marked them, keeping every measurement and price exactly as given.
Do I need a customer's approval before going over the estimate?
The FTC's Auto Repair Basics tells drivers the estimate should say the shop will contact them for approval before doing work beyond a set amount, and notes that state law may require it. Many states set their own rules on estimates and authorizations, so check yours and record when and how each approval was given.
What should I tell a customer who asks if we'll void their warranty?
The FTC says it's illegal for a manufacturer or dealer to deny warranty coverage simply because someone other than the dealer did the work, unless that work or an aftermarket part caused the problem. Tell them to keep every receipt. Give the general information, point them to the FTC's tips, and don't give legal advice about a specific warranty.
Should replaced parts go back to the customer?
The FTC tells drivers to ask for all replaced parts and notes that state law may require returning them. The pickup summary workflow has a line for it: kept for you, available on request, or returned as a core.
What should stay out of the AI chat at a repair shop?
VINs, plate numbers, customer names and phone numbers, card numbers and anything from a driver's license. Use the year, make, model and mileage, and let your shop system add the customer details to the final document.
