Customer Comeback Cadence for Auto Repair
Independent auto repair shops live on customer comebacks — and most don't run a comeback program. The customer who got an oil change 5 months ago is overdue for brakes; nobody calls. Customer goes to the chain across the street next time. This Formula installs the service-history-aware comeback agent that triggers reminders by service type, books the appointment when the customer replies, and runs an upsell cadence for related work.

The actual prompt. Copy it. Adapt it. Ship it.
This is the system prompt we'd configure on the agent for this Formula. It works on Hermes Agent, Claude, ChatGPT, OpenAI Agents, and any framework that takes a system prompt. The Install Pack includes the tested integrations, error handling, and deployment scripts that wrap around this.
You are the Customer Comeback Agent for an independent auto repair shop. Your job is to bring customers back at the right time for the right service. SERVICE-INTERVAL LOGIC: For each customer + vehicle, calculate the next-due service: - Oil change: typical 3,000-7,500 miles or 6 months - Brakes: based on prior wear measurement + estimated miles since - Tires: rotation every 5,000 miles, inspection every 3 months - State inspection: based on registration expiration - Other manufacturer-recommended services from the vehicle's profile OUTREACH: - 30 days before due: gentle SMS + email with the specific service due - 7 days before due: reminder with a one-tap booking link - On the due date: final reminder - Past due: escalate to service advisor for personal call (not automated) UPSELL: On any reply, check the service history for adjacent due-soon services: - "While you're in for oil change, your tires are also due for rotation. Want to bundle?" - Never push a service that isn't actually due. Customer trust is worth more than the upsell. NEVER: - Push services that aren't due (manipulation kills the relationship). - Quote prices for repairs without service-advisor approval. - Send messages outside 8am-7pm in customer's timezone.

How to install it step by step.
- Step 01
1. Pull the customer + vehicle history
Export from shop management. Verify each vehicle has VIN + last-service-date + last-mileage. Flag missing data for advisor cleanup.
- Step 02
2. Build the service-interval database
Manufacturer-recommended intervals per service type per vehicle category. The agent uses this to calculate next-due dates.
- Step 03
3. Set the reminder cadence templates
Reference the specific vehicle ('your 2018 Ford F-150') and the specific service ('oil change'). Avoid generic 'service reminder' messages — open rates die.
- Step 04
4. Wire the booking + bay-availability check
Customer reply → check next-available bay slot → confirm via SMS. Bundle adjacent due-soon services if accepted.
- Step 05
5. Pilot with 100 customers
First 100 customers: advisor reviews every reply before the agent confirms. Measure: comeback rate (target +15 points), bundle rate (target 20%+), opt-out rate (<5%).
Illustrative ranges. Not promises.
What this Formula typically lifts when installed correctly. Numbers are ranges drawn from typical operator data — not specific customer results.
What to watch for before you ship.
Not legal advice. Get counsel before going live. These are the common compliance + safety considerations for this Formula.
- ⚠TCPA: SMS to existing customers is generally allowed under established business relationship — but maintain the opt-out list.
- ⚠Manufacturer warranties: don't reference manufacturer-recommended intervals as 'required' if they're 'recommended.'
- ⚠Pricing: never quote without advisor approval — repair pricing varies by vehicle.

Yes. Reading is free, intentionally. Buying gets you the packaged ZIP, the official install path, the EULA covering your holdco's commercial use, free updates as we revise, and the 14-day refund. Most operators buy for the time savings + the license clarity, not because the content is paywalled.
