When a customer calls a trades business and no one answers, the caller does one of three things: leaves a voicemail, calls someone else, or waits. Missed-call text-back changes the second option by putting a message on their phone within moments of hanging up.
This guide explains how it works, what you need before it can start, and what to write.
How it works
- A customer calls your business number.
- Nobody answers, or the line is busy.
- An automation notices the missed call and sends a text from your business number to the caller.
- The caller replies or taps a link. You, or an automated assistant, take it from there.
It is a simple idea. The value is timing: a customer who has just failed to reach you is still holding the phone and still looking.
What a good message says
Short, clear, and honest about who it is from. Four ingredients:
- Who you are. Your business name, so they know which call it refers to.
- What happened. You missed their call.
- What they can do. Reply with the job details, or use a link to book.
- What to expect. When you will respond.
Example Wording you can adapt:
Hi, this is Test Plumbing. Sorry we missed your call. Reply with what you need and your address and we will get back to you today, or book here: [link]. Reply STOP to opt out.
Notes on the message:
- Do not promise an arrival time you cannot keep.
- Keep it under a couple of short sentences.
- Include opt-out language if your texting setup requires it.
- Use your real business name, not a vague greeting.
- Do not send a long sales message to someone who only called once.
What you need before it can start (US)
A business number that can text
Many business landlines and some VoIP numbers can be enabled for texting. Your phone provider can tell you what applies to yours.
Carrier registration (A2P 10DLC)
US carriers require registration for automated business texting from standard local numbers. You register two things: the business (name, legal details, address, tax identifier) and the campaign (what messages you send and why). The carriers review it.
Plan for these facts:
- Approval is not instant and not in your control. Start early.
- Details must match. The business name and address you register should match your other records.
- Texts may be blocked or filtered until approved. Do not rely on texting in the meantime.
- Registration is in your business’s name. It is your sender identity.
At Biz Up, you submit the registration from your own account with our step-by-step guide, because the identity is yours, and texts start when the carriers approve it. See how going live works.
Respect for consent and opt-outs
Texting rules in the US involve federal law and carrier policy. The details depend on what you send, to whom, and whether it is marketing. A text that responds to someone who just contacted you is a different thing from a promotion sent to a list. Always:
- honour STOP replies immediately and keep a record;
- avoid texting at unsociable hours;
- keep messages relevant to the call;
- ask your own adviser if you plan any marketing texts.
This is general information, not legal advice.
What happens when they reply
A reply is the start of a conversation, so decide who handles it.
- You, from a phone or app. Fine for low volume, but it needs discipline.
- An automated assistant. It can ask for the job and address and offer a booking link, then hand the thread to you.
- A team member. Works if someone is assigned.
The reply path matters more than the first text. A text-back with no one watching the replies is a missed call with extra steps.
Text-back versus answering the call
Be clear about what each does.
| Text-back | AI receptionist | |
|---|---|---|
| Customer experience | Gets a message after they hang up | Is heard during the call |
| Capture of job details | Only if they reply | Asked for on the call |
| Setup dependency | Carrier registration | Call forwarding, and registration for follow-up texts |
| Weak spot | Callers who never read texts | Callers who dislike talking to an AI |
They work together. The AI answers the call, and a text confirms what was captured and offers a booking link. If you only want the cheap first step, start with text-back, and add call answering when you see the missed-call count. See what missed calls cost for how to count it.
Common mistakes
- Starting without registration. The text goes nowhere and you do not notice.
- Texting for every call. Do not text existing customers who rang about a job in progress without a rule to exclude them.
- Using it as marketing. Keep to the call.
- Nobody reads the replies. Assign an owner.
- Wrong hours. A text at 3 am saying “we will call you this morning” is fine. A text saying “we are open now” is not.
Setting it up
- Confirm your number can send texts.
- Start A2P 10DLC registration with accurate business details.
- Write the message and review it.
- Decide who handles replies and how fast.
- Test by calling your own number from another phone and letting it go unanswered.
- Check after a week: how many replies, how many bookings.
The AI Voice Wizard includes missed-call text-back and an AI that answers calls. It is part of the AI Voice + Review Wizard plan. For an example of an AI answering a trade business call, see AI receptionist for plumbers.
