Phones & Booking

A one-man garage installer asked what an AI phone agent needs before he trusts it. The answer: don't let it improvise

Fixed price list, a zip-code check, preset time slots. Anything else becomes a message.

Real storyDone with AI voice agent (Bland mentioned by a commenter)

What they did

u/ccchhannn does garage installs and repairs alone, so his phone is "basically a paperweight from 8 to 5." He wanted an AI agent to answer service-area and rate questions and book or take a useful message, but worried it would quote prices he never set or book jobs 40 minutes away.

How it went

One commenter said they use Bland and started conservative with service areas, basic questions and messages only, then expanded once they trusted it. Others gave the same advice: give it a fixed price list it can only read from, a zip-code list, and slots you preload. If anything is unclear, it takes a message and promises a callback.

Worth knowing

One commenter noted that if you only drop about 5 calls a week, a cheap human answering service may be the better buy.

Try it yourself

You are a call-flow designer for a one-person trade business. TASK: Write the guardrails and script for an AI agent that answers my phone while I'm on jobs. CONTEXT (fill in the [BRACKETS]): - SERVICES: [SERVICES] (example: garage door install, spring replacement, opener repair) - SERVICE AREA ZIPS: [SERVICE AREA ZIPS] (example: 53005, 53045, 53072, 53186) - APPROVED PRICE RANGES: [APPROVED PRICE RANGES] (example: spring replacement $250-350, opener install $450-700) - BOOKABLE SLOTS: [BOOKABLE SLOTS] (example: Tue/Thu 3-5pm only) - MY NAME: [MY NAME] (example: Matt) STEPS: 1. Write the greeting that says it's an assistant for my business. 2. Write the zip-code check and the polite 'outside our area' reply. 3. Write price answers using ONLY my ranges, ending with 'Matt confirms the final price.' 4. Write the message-taking script: name, number, address, problem, urgency, photo request by text. 5. List 8 things it must never do. RULES: - Use only the facts I give you. If something is missing, ask or mark it NEEDED. Never invent prices, names or promises. - Plain, friendly language a customer or crew member understands. OUTPUT FORMAT: A full call script in order, then the never-do list. FOLLOW-UPS TO TRY NEXT: - Write the text summary I get after each call. - How many missed calls a week makes this worth it vs. an answering service?
