Missed calls at an auto repair shop: a 7-step checklist for the text-back

Phones still decide where most people take their car. In AutoZone's May 2025 survey of 1,015 do-it-for-me customers, 67% said they prefer to book auto repair appointments by phone; 28% chose online booking and 13% text, and respondents could pick more than one (AutoZone / Endeavor Business Intelligence, PDF). The same report found 20% of shop owners also work as technicians, which is exactly who isn't near the phone at 10 a.m.

How many calls go unanswered? OktoRocket, which sells shop software and an AI phone system, says the typical independent shop in its 2025 benchmark of over 1,000 shops gets 800+ calls a month, answers about 89% of them, and the median shop misses over $16,000 a month in revenue from unanswered calls (Business Wire release, July 30, 2026). That's a vendor's own benchmark, so treat it as a ballpark. You'll also see "a quarter of calls go unanswered" on many blogs; we couldn't trace that to a primary source, so we don't use it.

This checklist walks through the missed-call text-back recipe for auto shops, one of five on our auto repair hub. Everything below was verified with mocks of Shopmonkey and Twilio, not a live shop.

The checklist

1. Forward calls through a number you can watch

Your Twilio number rings your existing shop line. When the forwarded call ends as busy, no answer or failed, the workflow takes over. A completed call does nothing: in our test, an answered call produced no text, no email and no log row (scenario AR1-01).

2. Send one short text, by first name if you know them

Here's the text our test run produced for an invented customer found in the Shopmonkey mock (AR1-02):

Hi Dana, sorry we missed your call at Riverside Auto Care. Reply here with what you need and a service advisor will get back to you. Reply STOP to opt out.

Callers who aren't in Shopmonkey get a generic version asking for the year, make and model. No prices, no promises, no diagnosis.

3. Put the open order in front of the advisor

The point isn't the text; it's the callback. The advisors' email looks the caller up in Shopmonkey by phone and shows the name, the vehicle and any open order (in our run, an estimate waiting on approval). Phone numbers stored as "(555) 555-0322" still matched "+15555550322" (AR1-07). If someone calls about an unapproved estimate, the estimate approval escalation recipe has probably already flagged it too.

4. One text per number per 12 hours

A second call two hours later got no second text, but the office was told they'd called again (AR1-03). Nobody wants three identical texts after redialing.

5. Respect the clock

The FCC's rule (47 CFR 64.1200) bars telephone solicitations before 8 a.m. or after 9 p.m. in the called party's local time. A text-back to someone who just called you isn't a cold pitch, but we hold texts after 9 p.m. anyway. In our test, a 10:30 p.m. call got its text at 8:00 a.m., not at 7:45 and not twice (AR1-04, AR1-05). Our texting consent page covers the rest; ask your attorney whether a missed-call text fits your situation.

6. Make STOP work in plain English

"STOP" and versions like "stop texting me" go to one shared opt-out list. After a STOP, a later missed call got no text and the office was told to call instead (AR1-10). START turns texts back on (AR1-11). The same list covers the car-ready pickup message and the after-hours drop-off check-in.

7. Forward replies to a person

Replies land in the advisors' inbox with the Shopmonkey context. The customer gets one "got it" text, not one per message, and none at night (AR1-12, AR1-13).

What broke in testing (on purpose)

All 16 scenarios passed against the mocks. How we run those mocks is on how we test.

What it costs

Illustrative arithmetic from Twilio's US price pages (checked October 2026, your volumes will differ): 300 forwarded calls a month at 2 minutes each is 600 minutes x ($0.0085 to receive + $0.0140 to forward) = $13.50 (Twilio Voice pricing). Add a $1.15/month number, texts at $0.0083 per segment plus carrier fees, and the A2P 10DLC registration US carriers require. Full numbers are on the recipe page.
