Missed Call Text Back for Contractors: Setup, Rules and Scripts

Missed call text back is an automation that sends a short text to anyone whose call you miss, letting them know you saw the call and asking what they need. For a contractor on a roof or under a house, it keeps the caller talking to you instead of dialing the next company on the list. It is cheap and quick to set up in a business phone app like Quo or an all in one tool like HighLevel, but not in Google Voice. Before you turn it on, you need two things right: your number registered for business texting, and a working way for people to opt out by replying STOP.

What is missed call text back?

The flow is simple. A call to your business number goes unanswered, the system sends a text from that same number, and the customer's reply lands in a shared inbox where you or your office can pick it up.

Quo, for example, says it can "automatically send texts based on missed calls, new voicemails, and incoming text messages," with different replies inside and outside business hours. It also limits repeats: "We won't send automated texts to the same number more than once every three hours" (Quo SMS autoresponder).

It is not an answering service. Nothing talks to the caller. That makes it far cheaper and simpler than an AI answering service, and also less capable: it starts a conversation, then a person has to finish it.

Should you text back or call back?

Both. The text goes out right away, while the caller is still deciding who to call. Then call back yourself for anything that looks like a real job. Some callers are on office lines that cannot receive texts, and some people simply prefer a voice. The text buys you time; it does not replace the callback.

Where to set it up

Business phone apps. Quo supports auto replies for missed calls and voicemails. As of October 2026, its Starter plan is listed at $15 per user per month billed annually, or $19 billed monthly (Quo pricing).

All in one marketing tools like HighLevel. HighLevel's help center describes a Missed Call Text Back setting: "If missed, Missed Call Text Back (if enabled) texts the caller from the LeadConnector number" (HighLevel support). Note that the text comes from HighLevel's number, and its Google Business Profile call tracking moves your existing number to the secondary slot on your profile. Understand that before you agree to it.

Field service software. Jobber's AI Receptionist can text callers who hang up before it starts a conversation, according to Jobber's help center. Housecall Pro's help center confirms that with its Voice feature, missed calls show up in your inbox chat feed (Housecall Pro help). We could not confirm a built in automatic text back on Housecall Pro's public pages, so ask your rep.

Not Google Voice. Google's own rules say Voice texting is "intended only for interactive conversations" (Google Voice help), and its acceptable use policy prohibits "sending messages via an automated process, such as a script" (Google Voice acceptable use policy). Google says it may limit or terminate access for policy violations, so bolting an auto reply onto Google Voice risks losing the number.

How to set up missed call text back

1. Use the number customers already call. The one on your Google profile, trucks and website. If you are moving to a new phone app, port the number or forward it, but do not start texting from a number nobody recognizes.
2. Register for business texting. Your provider walks you through it (more below). Expect it to take some time, so start now.
3. Write two messages: one for business hours, one for after hours. Scripts are below.
4. Include opt out wording such as "Reply STOP to opt out."
5. Set a repeat limit so someone who calls three times does not get three texts.
6. Pick who watches replies, and set a response time you can keep, such as within 30 minutes during business hours.
7. Test from two or three phones, including one that has never called you, and check that the message clearly names your business.
8. Review the replies weekly and adjust the wording.

Scripts you can copy

Keep it short, say who you are, and ask one question. No prices, no links, no promises you cannot keep.

During business hours

"Hi, this is [name] at [company]. Sorry we missed your call, we're on a job right now. What can we help you with? Reply STOP to opt out."

After hours

"Thanks for calling [company]. Our office is closed, and we'll get back to you after [opening time]. If you have an emergency, call us back and stay on the line for our on call tech. Reply STOP to opt out."

When they left a voicemail

"Hi, it's [company]. We got your voicemail and will call you back by [time]. Reply STOP to opt out."

Only use the emergency line if your phone system actually routes emergencies. Never promise a response time you cannot meet.

The rules: carrier registration, consent and STOP

A2P 10DLC registration. US carriers require businesses texting from ordinary local numbers through software to register. Twilio's documentation describes A2P 10DLC as "the standard that United States telecom carriers have put in place to ensure that SMS traffic to US end users through long code phone numbers is verified and consensual," and says unregistered senders pay "additional carrier fees" (Twilio A2P 10DLC docs). Jobber's help center likewise says businesses texting from its dedicated numbers are required to register in the United States (Jobber dedicated phone number). Registration covers who you are (the brand) and what you send (the campaign), including how people opt in and opt out.

STOP and other opt outs. Under the FCC's rules, a reply of "stop," "quit," "end," "revoke," "opt out," "cancel," or "unsubscribe" is a valid way to revoke consent, and opt outs must be honored "within a reasonable time not to exceed ten business days" (47 CFR 64.1200, eCFR). The same rule allows one confirmation text with no marketing in it. CTIA's industry guidelines recommend standard STOP wording and say ordinary phrases like "please opt me out" should be honored too (CTIA Messaging Principles). Treat any reply that clearly means "stop texting me" as an opt out.

Do not turn it into a marketing list. A one time reply about a call someone just made to you is very different from sending promotions later to everyone who ever called. Get proper consent before any marketing texts, and talk to your attorney about the details for your business.

What to watch out for

• Two tools firing at once. If your phone app and your marketing tool both send a text back, customers get two. Pick one.
• Nobody reading replies. A text back with no human follow up is worse than none.
• Spam callers get texts too. Use your provider's spam blocking where it exists.
• Texting from a new number. Customers ignore unknown numbers. Keep your main number in front.
• Unregistered numbers. Messages from unregistered numbers can be filtered or cost more. Finish registration before launch.

Where to start

Check whether your phone app or field software already has missed call auto replies, register your number for business texting, and turn on the business hours script for two weeks.
