Missed-call text-back: the cheapest automation a contractor can install

Missed-call text-back sends an automatic text message to anyone whose call you didn't answer, usually within a few seconds: "Sorry we missed your call, this is Dave from Northline Roofing. What can we help with?" For a contractor on a roof, under a sink or driving between jobs, it turns a missed call into a conversation the customer can continue by text instead of calling the next company on the list. The messaging itself costs pennies; what you pay for is the software that detects the missed call and sends the reply, typically included in a CRM or phone system you may already be paying for. It's one of the few automations that's cheap, fast to set up and easy to judge.

Why it works for trades

Homeowners looking for a contractor rarely call just one. If your phone rings out, the next name in the search results is a tap away. A text that arrives while they're still holding the phone does three things:

• it tells them a real business received the call;
• it gives them an easy way to describe the job without waiting for a callback;
• it keeps your name at the top of their messages while they decide.

It also fits how contractors work. You can't answer a call with a nail gun in your hand, but you can reply to a text at lunch with a photo request and a time for a visit.

How it works behind the scenes

The system needs to see your calls, so your business number has to run through software that can detect an unanswered call and send a text from the same number. There are three common set-ups:

1. Your phone system or CRM already supports it. Many business phone apps and CRMs include missed-call text-back as a ready-made automation. You switch it on and write the message.
2. Forward unanswered calls to a new number. You keep your existing number and set "forward when busy or no answer" with your carrier to a text-enabled number in the software. The customer gets the text from that number, so it should be a local number in your area code.
3. Port your number to the platform. All calls and texts run through the software. This gives the cleanest experience, but porting a number you've had for years needs planning so you don't lose calls during the switch.

Whichever you choose, replies must reach a person. Set the software to notify your phone (or whoever handles the office) the moment a customer texts back.

Limits to know about

• Landlines can't receive texts. Callers from a landline won't see the message. For residential trades, most callers use mobiles; for commercial clients calling from an office line, the text goes nowhere.
• Blocked numbers get nothing. No caller ID, no text.
• Not every missed call is a lead. Suppliers, existing clients and robocalls will get the text too. Write the message so it makes sense for all of them.

Message templates you can adapt

Keep the first message short, personal and easy to answer. One question is enough.

The standard reply

Hi, this is Dave at Northline Roofing. Sorry we missed your call, we're on a job. What can we help you with? Reply here and we'll get back to you today.

With a photo request (repairs, damage, quotes)

Hi, Northline Roofing here. Sorry we missed you. If it's about a repair, feel free to text a photo and your address and we'll look at it right away.

After hours

Thanks for calling Northline Roofing. We're closed for the day and back at 7 a.m. Text us what you need and we'll reply first thing.

For trades with emergency service

This is Brightwater Plumbing. Sorry we missed your call. If water is actively leaking, call again and choose option 1 for our emergency line. Otherwise, text us what's going on.

A single follow-up if there's no reply (a few hours later, once only)

Hi, just checking in from Northline Roofing. Still need help with your roof? Happy to book a time to take a look.

A few rules for writing these:

• Use your business name in the first line. People don't save contractor numbers.
• Don't promise what you can't deliver. "We'll call within 10 minutes" breaks trust the first time you're on a ladder.
• Never send prices, promotions or links to deals in the first message. It's a reply to a call, not an ad.
• Keep it under one text. A standard SMS holds 160 characters of plain text; accented letters and emoji switch the message to a format that holds far fewer, which can split it into several billed parts. That matters for French messages too.

What it costs

There are two cost layers.

Messaging. Twilio, one of the main carriers behind these tools, lists Canadian SMS at US$0.0083 per message segment, sent or received, plus carrier fees, and a local number at US$1.15 a month. A contractor with 100 missed calls a month, sending two segments each, pays a couple of dollars in messages. Platforms that resell messaging add a margin, but the totals stay small.

Software. This is the real cost. Missed-call text-back is rarely sold alone; it comes inside a CRM, a business phone system or a marketing platform. GoHighLevel's own plans, which agencies use to run client accounts, start at US$97 a month, with phone and SMS billed separately on top. Business phone apps and contractor CRMs include it at a range of price points. If you already pay for one of these tools, check whether the feature is included before buying anything new.

Set-up. If the feature is built into your phone system, writing the messages and testing takes an hour or two. If it needs call forwarding, a new number and a connection to your CRM, budget for a day of set-up and testing, or an agency fee.

To judge it, count the jobs. If one extra job a month comes from a caller who would otherwise have phoned a competitor, the automation has paid for itself many times over.

The rules in Canada

Text messages are covered by Canada's anti-spam law (CASL). It prohibits sending a commercial electronic message without the recipient's consent, express or implied, and the law's definition of an electronic address explicitly includes telephone accounts.

For missed-call text-back, two parts of the law are relevant:

• Implied consent from an inquiry. CASL treats an inquiry about your products or services, made within the six months before you send a message, as creating an existing business relationship and therefore implied consent. A person who just called your business line is, on a reasonable reading, making an inquiry.
• Requested quotes are exempt from the consent requirement. A message that solely provides a quote or estimate the person asked for doesn't need consent.

In practice:

• Keep the automated reply about their call, not your promotions.
• Identify your business clearly in every message.
• If someone texts "STOP" or asks you not to contact them, stop, and make sure the software records it.
• Don't add callers to a marketing list without asking. A separate, explicit consent is the clean way to do that.

This is general information, not legal advice. If you plan to use these contacts for marketing campaigns, check the details with a lawyer.

When it's not worth setting up

• You answer nearly every call already. Someone in the office picks up during business hours, and after-hours calls are rare.
• Most of your callers use landlines, as with many commercial and industrial clients.
• Nobody will answer the replies. A text-back that leads to silence is worse than voicemail, because it signalled that someone was there.

Going further

Missed-call text-back is the first step. The natural next ones are a short automated sequence that asks for photos and books a site visit, a reminder the day before the appointment, and a review request after the job. If you get many after-hours calls, an AI receptionist can take the call itself instead of texting back; see our guide on AI receptionist costs in Canada to compare.

Where PNE fits
