This guide covers how missed-call text-back actually works, what it really costs, whether you should just build it yourself, and the texting rules that can land a contractor with a five-figure problem.
I sell one of these services. I've tried to write the guide I wanted when I was looking, which means it includes the parts that don't help me — including a section on doing it yourself for about four dollars a month.
When someone calls your business and nobody picks up, a missed-call text-back system automatically sends that caller an SMS — typically within a minute. Something like "Sorry I missed you, I'm on a job site. What do you need help with?"
That's it. That's the whole mechanism. The reason it works isn't clever technology, it's behavioural: people ignore voicemail and answer texts. A voicemail asks the customer to do work — listen, wait, call back. A text lets them reply with one thumb while they're still annoyed about the furnace.
Better systems then handle the reply too — asking what's wrong, offering a time, confirming a booking — and only hand the conversation to you when there's a real job in it.
A homeowner with a broken water heater is not calling one plumber. They're working down a list of three or four, in order, until somebody picks up. Every minute you take to respond is a minute in which that list gets shorter.
Research on small-business phone handling has consistently found that a large majority of calls go unanswered, and that most callers who can't reach a business never call back — they contact a competitor instead. The often-cited figures are around 62% of calls unanswered and 85% of unreached callers never returning.
You don't need those exact numbers to be right. You only need the direction to be right, and every contractor already knows it is, because you've been on both ends of it.
This isn't lead generation. You already paid for that lead — through your truck wrap, your Google listing, your reputation, or a referral. Missed-call text-back is about not throwing away leads you've already bought. It's the cheapest marketing spend available to you, because the acquisition cost is already sunk.
Run this with your own figures rather than mine.
| Line | Your number | Example |
|---|---|---|
| Average value of a service call | _____ | $400 |
| Calls missed per week | _____ | 4 |
| Share who never call back | _____ | 85% |
| Weekly loss | _____ | ≈ $1,360 |
| Annual loss | _____ | ≈ $70,000 |
Most contractors doing this exercise for the first time land on a number that makes the monthly cost of any of the options below look trivial. That's the honest case for doing something. It is not an argument for doing something expensive.
| Option | Typical cost | Best for |
|---|---|---|
| DIY with Twilio | Under $5/mo in usage | Technical owners who'll maintain it and own compliance themselves |
| Business texting app (OpenPhone, Textline) | ~$15–21 per user/mo | Teams who want a shared inbox and will handle replies manually |
| Self-serve platform (GoHighLevel and similar) | $97–297/mo | Owners willing to configure and maintain the automation themselves |
| Done-for-you service (national vendors) | $399/mo and up | Owners who want it set up, tuned and monitored for them |
Prices are list rates as of mid-2026 and move around. Check before you commit.
Colorado Trade Leads is $255 a month with no setup fee — done-for-you, but priced under the national vendors because we're one contractor serving Colorado rather than a software company with a sales floor. If the DIY route below appeals to you, genuinely do that instead. It works.
If you're comfortable with a bit of configuration, this is a weekend project and it costs almost nothing to run.
What you're taking on: reliability (if it breaks at 6pm on a Friday, you fix it), deliverability, carrier registration, and compliance. None of that is hard. All of it is yours.
I'm a contractor, not a lawyer. If you're texting at any real volume, an hour with an attorney who knows the TCPA is the cheapest insurance you'll ever buy. What follows is the shape of the thing, not a legal opinion.
The critical distinction is who made contact first. Texting back a homeowner who dialled your number sixty seconds ago is a response to an inbound enquiry. Texting a list of people who never contacted you is cold marketing, and that is where the serious statutory damages live — potentially hundreds to over a thousand dollars per message.
Practically: use text-back for people who called you. Don't buy a list and blast it.
If someone replies STOP, UNSUBSCRIBE, QUIT, or anything reasonably meaning that, they must come off immediately and stay off. Build this before you build anything else, and make it fail closed — if your opt-out list can't be reached, don't send.
The standard window is 8am to 9pm at the recipient's location. A queued text firing at 6am is exactly the kind of avoidable mistake that turns into a complaint.
US carriers require business SMS traffic to be registered (A2P 10DLC). Skip it and your messages quietly stop being delivered — which is worse than not sending, because you'll think it's working.
Several states, Colorado included, have their own telemarketing registration requirements on top of federal law. Worth ten minutes on your state Attorney General's site.
Three honest questions.
Is your evening worth more than $250 a month? If yes, buy. If no, and you enjoy this kind of thing, build it. Both are respectable answers.
Who owns it when it breaks? Any automated system touching customers will eventually misfire. Decide now whether that's your problem or someone else's, because the answer changes what you should buy.
Are you being sold a system or an outcome? You don't want software. You want to stop losing jobs. If a vendor is selling you dashboards, integrations and seat licences, they've confused their product with your problem.
Colorado Trade Leads does all of the above for Colorado trade contractors — text-back in under 60 seconds from your existing number, live in one business day, $255 a month with no setup fee and no contract.
