For a solo owner who just wants a text to go out when they can’t pick up, Quo is the cheapest well-documented option, from $15 a user a month billed annually. If you already run an agency on GoHighLevel, its text-back is built in from $97 a month plus usage. Podium does it inside a bigger messaging platform that starts at $399 a month. Stack Space takes a different route: an AI receptionist answers the call, and the text-back catches callers who hang up first, from $30 a month.
Every one of these has a cost that isn’t on the sticker: in the US, texting from a business number needs carrier registration, and some tools pass those fees on to you. We sell one of the four, so weigh that, but every competitor fact below links to the vendor’s own page, checked October 2026.
What should missed-call text-back software actually do?
The feature itself is simple: someone calls, nobody answers, and a text goes out (“Sorry we missed you, how can we help?”). The differences are in the details that decide whether it works for you:
- Which number the text comes from. A text from the number they just called reads as you. A text from an unfamiliar number has to say who it’s from, or it reads as spam.
- Carrier registration. US carriers require business texts from 10-digit numbers to be registered (A2P 10DLC). Twilio blocks texts from an unregistered 10-digit number outright.
- How calls reach it. Phone apps like Quo and GoHighLevel want you to move your number to them or use theirs. An AI receptionist usually works by forwarding calls from the number you already have, either every call or only the ones you don’t pick up. Ask who registers, what it costs, and how long it takes. Our 10DLC rejection guide covers what goes wrong.
- Repeat callers. Someone who calls three times in five minutes shouldn’t get three identical texts.
- What happens after they reply. A reply that lands in a shared inbox, next to the customer’s history, gets answered. A reply that lands on one employee’s phone often doesn’t.
- Whether anything answers the call. Text-back is a net for calls you missed. It doesn’t answer the caller’s question while they’re on the line.

Quo: the cheapest clean option for a small team
Quo (formerly OpenPhone) is a business phone app, and auto-replies come with every plan. Its guide lists four separate replies: missed calls with or without a voicemail, during and after business hours. It sends at most one auto-reply every three hours to the same number, which handles the repeat-caller problem for you.
What it costs, per Quo’s pricing page: Starter is $15 a user a month billed annually ($19 monthly), Business $23 ($33), Scale $35 ($47). Each user gets one number. Carrier registration is $19.50 one-time, plus $1.50 to $3 a month in messaging fees.
Quo also includes an AI agent, Sona, that answers calls: every plan includes 1,000 credits a month (about 10 calls), with paid credit tiers from $25 a month after that.
Pick Quo if you want a phone number that texts back and nothing else changes about how you work. Look elsewhere if you need the reply to feed a CRM with your jobs, invoices and follow-up in it, or you want most calls answered by AI without buying credits. Quo offers a 7-day risk-free trial.
Hear the receptionist take a real call — it rings your phone in about a minute.
GoHighLevel: built in, if you’re already there
GoHighLevel’s missed-call text-back lives in Settings → Phone System → Voice. It texts from the number the caller dialed if that number can text, and falls back to another number if not. It needs HighLevel’s phone system, an SMS-capable number and A2P registration for local numbers.
Two things to know. First, it fires on every missed call, including the same person calling three times; HighLevel’s own article suggests building a workflow with delays or filters to stop duplicates. Second, usage is billed on top of the plan: $1.15 a month per local number and $0.00747 per text segment, sent or received (HighLevel phone pricing, September 2026), plus the carrier registration fees. Plans are $97, $297 or $497 a month, with a 14-day free trial.
Pick GoHighLevel if you’re an agency already running clients on it. The text-back is one setting among hundreds. Look elsewhere if you’re a single business; $97 a month plus usage and setup is a lot for one feature. Our GoHighLevel pricing guide walks through the full bill.
Podium: text-back inside a bigger platform
Podium’s phone system will “automatically text missed or after-hours calls,” and its AI Employee can carry on the conversation by text. It sits inside Podium’s broader platform of reviews, webchat, payments and a shared inbox.
Podium’s pricing page (October 2026) lists Core at $399 a month and Pro at $599, plus a $5 monthly texting fee per US location. Its phone system is $30 a user a month (1–4 users) plus a $500 network optimization fee per location. The AI Employee price isn’t published; CheckThat.ai (April 2026) reports $99 to $399 more (details in our Podium pricing teardown). HVAC businesses are told to contact sales for pricing.
Pick Podium if texting is how your customers want to deal with you and you’ll use the reviews, payments and webchat too. Look elsewhere if text-back is the only thing you’re buying.
Stack Space: answer the call, text the ones who hang up
We built this the other way round. Forward your business number to the AI receptionist, and it answers every call 24/7 within your plan’s minutes: it asks what the caller needs, books them onto your calendar and sends you a summary. So a call it answers never becomes a missed call.
The text-back is the net underneath. Turn it on in settings, and a caller who hangs up before speaking gets a text from your business after the call. It goes out from our registered number and opens with your business name, so it works without your own carrier registration. That’s a different number from the one they dialed; if you want texts and replies on a number of your own, add a managed text number ($15/mo). It reaches US and Canadian numbers, and it texts on every hang-up, with no repeat-caller window yet. It also goes out when your receptionist minutes have run out and the call can’t be answered. Replies land in the same inbox as the call recording and the customer’s history, and the texts are metered by segment from your plan’s text allowance: 150 a month on Launch, 800 on Starter.
Plans are $30 (Launch, 45 receptionist minutes), $125 (Starter, 250 minutes), $355 and $800 a month, with no free trial. Marketing texts, like a promo to your whole list, wait on your own carrier registration.
Pick Stack Space if what you actually want is fewer missed calls, not better apologies, and you’d use a CRM with booking, estimates and invoices. Look elsewhere if you only want a phone number that texts back; Quo does that for less.
What does each cost for a real business?
Take a two-truck plumbing shop that misses about 60 calls a month and has one person on the phone, paying monthly:
| Plan | Text-back usage | Registration | First month | After that | |
|---|---|---|---|---|---|
| Quo Starter | $19 | Included | $19.50 + $1.50–$3 | $40–$42 | $21–$22 |
| GoHighLevel Starter | $97 + $1.15 number | 60 texts ≈ $0.45, plus carrier fees and any replies (under $1) | $22.50 + $1.50–$10 | $123–$131 | $100–$109 |
| Podium Core | $399 + $30 phone seat | Included | $5/mo, plus $500 one-time network fee | $934 | $434 |
| Stack Space Launch | $30 | From the 150 included texts | None for text-back | $30 | $30 |
| Stack Space Starter | $125 | From the 800 included texts | None for text-back | $125 | $125 |
HighLevel bills carrier registration separately: $22.50 one-time for a low-volume brand and $1.50 to $10 a month per campaign (fee page, September 2026). Podium’s figures are from its pricing page (October 2026): the $5 is its 10DLC fee per US location, the phone seat and the $500 network optimization fee per location apply because text-back runs on Podium’s phone system, and payment processing comes on top. The rows also aren’t doing the same job. Quo and GoHighLevel text the caller back. Stack Space’s receptionist answers the call first, and 45 minutes on Launch covers roughly 11 to 22 answered calls (at two to four minutes a call), so a shop missing 60 a month would want Starter ($125, 250 minutes) to have the AI answer most of them. On Launch, once the 45 minutes are used, callers hear a short message that you can’t answer and get the text.
How do you choose?
- Count your missed calls. Last month’s call log tells you. Five a week is a different problem from five a day.
- Decide whether you want a text or an answer. A text might get a reply. An answer gets a booking while they’re still on the line.
- Ask who handles carrier registration, and what it costs. It’s the hidden setup step, and it can take weeks if a campaign is rejected.
- Test it. Call your own number from another phone, hang up, and see what arrives and from which number.
If you want the setup steps and templates for any provider, our missed-call text-back guide has them, and forwarding calls to an AI receptionist covers the carrier codes. For texts written for a specific trade, see the HVAC and roofers and electricians versions.
FAQ
What is the best missed call text back software?
It depends on what you need around it. Quo is the simplest and cheapest for a small team (from $15 a user a month billed annually). GoHighLevel has it built in for agencies (from $97 a month plus usage). Podium bundles it with reviews and payments, from $399 a month. Stack Space pairs it with an AI receptionist that answers the call first, from $30 a month.
How much does missed call text back cost?
From about $15 to over $400 a month depending on the platform, plus carrier registration. Podium lists $5 a month per US location for registration and $30 a user a month for its phone system on top of its $399 Core plan. Quo charges $19.50 one-time and $1.50–$3 a month for registration on top of its plans. GoHighLevel bills $0.00747 per text segment and $1.15 a month per number on top of its plans.
Do I need A2P 10DLC registration for missed call text back?
If the text goes out from your own 10-digit business number in the US, yes. Some platforms send from a number that’s already registered; Stack Space’s text-back goes out from our registered number with your business name, so it works without your own registration.
Does GoHighLevel’s missed call text back text the same person twice?
Yes. HighLevel’s help article says it triggers on every missed call, even when the same caller tries several times in a short window, and recommends a workflow with delays or filters to avoid duplicates.
Is missed call text back enough on its own?
It’s better than voicemail, but it’s still a text after the fact. If missed calls are costing you jobs, an AI receptionist that answers them is the bigger fix, with text-back as the backup.
