Your customers would rather text you

Call a customer under forty and listen to what happens. Half the time it rings out to voicemail, and twenty minutes later they text you back asking what you needed. That’s not rudeness. It’s how people talk now. A text gets read inside a few minutes. A voicemail sits there all day, if they ever bother checking it at all.

For a trades business that’s a gift. You confirm the appointment, you send the “on my way,” you fire over the quote, and you get an answer back without playing phone tag across a whole work day. But texting a customer isn’t the same as texting your buddy. And there’s a federal law with real teeth sitting behind it that plenty of owners have never heard of. Get both right and texting is the best tool on your phone. Get them wrong and it costs you the job, or a fine with a lot of zeros on it.

Text like a professional, not a teenager

The etiquette is mostly common sense, right up until you’re thumbing out a message between jobs with grease on your hands and half your head on the next call. So here’s the short version.

Say who you are. Every time you start a thread, at least. “Hey, it’s Dave from Ace Plumbing.” Your number is saved in that customer’s phone as nothing at all, so a cold text opening with “running late, be there by two” reads like a scam or a wrong number. Ten seconds of introduction and they know it’s you.

Mind the hours. Nobody wants a work text at six in the morning or ten at night, and as it happens the law feels the same way, more on that below. Keep business texts to normal daytime hours unless the customer texted you first about an emergency. And keep it about the job. A thread with a customer isn’t the place for jokes or a wall of emojis. Professional, short, done.

Answer like a person, and answer fast. Speed is the whole reason texting works in the first place. A reply that lands three days later might as well never come, because by then they’ve called the next name on the list. If you can’t watch the thread yourself all day, that’s exactly the sort of thing an office person or a system ought to be catching for you.

The law nobody warned you about

Here’s where people get tripped up. There’s a federal law called the TCPA, the Telephone Consumer Protection Act, and it governs how a business is allowed to text and call people. It got written for robocalls and junk, but it’s broad, and a one-truck plumber texting his customers falls under it the same as a giant call center does. The penalties run per message, from a few hundred dollars up into the low thousands for each one. Text a hundred people who never agreed to hear from you and that math turns ugly in a hurry.

You don’t need a lawyer on retainer to stay clean. You need one idea: consent. You can text a customer who handed you their number and a reason to expect you’d use it. Somebody who books a job and gives you their cell has basically said “text me about this job.” The appointment reminder, the “on my way,” the invoice, the follow-up a week later, all of that sits in the safe lane. And that lane covers most of what a trades business ever needs to send.

It gets dicey with marketing. Blasting “20% off drain cleaning this month” to your whole list is a different animal from an ETA text, and it needs a clearer, stronger yes before it goes out. Buying a batch of phone numbers and texting strangers is the express route to a fine. Rule of thumb: if they gave you the number for a job, texting about that job is fine. Want to send promos? Get them to actually opt in first, and keep a record showing they did.

Staying on the right side of the TCPA
Text only who opted in

If they didn't give you the number, don't text it. No bought lists, no strangers.

Say who you are

Your business name on every thread, so nobody mistakes you for spam.

Honor STOP instantly

The second they opt out, you're done. No last message, no exceptions.

Keep marketing separate

Job texts are one thing. Promos need their own clear yes from the customer.

Mind the clock

Daytime hours only, unless they texted you first about an emergency.

Keep records

A note of who agreed to what, in case anyone ever asks you to prove it.

Honor 'STOP' the second it lands

One rule outranks all the rest, and it’s the one people fumble. When a customer replies STOP, or “quit texting me,” or “take me off the list,” you’re finished. No more texts. Not a “sorry to see you go,” not one last promo, nothing at all. The law treats that opt-out as immediate and absolute, and running past it is one of the surest ways to turn a mild customer into a complaint with a dollar figure stapled to it.

This is right where doing it by hand falls apart. Say you’re texting off your personal phone and a guy tells you to knock it off in March. You going to remember that in July, when you’re firing a seasonal promo at your whole list? Course not. You’ll text him anyway, and now you’ve handed yourself a problem you didn’t have to have. Honoring opt-outs is exactly the kind of job that belongs in a system, not your memory.

If they gave you the number for a job, texting about that job is fine.

Where ToolbagCRM fits

All of this gets easier the moment the texting runs through your CRM instead of your personal cell. ToolbagCRM has two-way texting built in, tied to each customer’s record, so the whole conversation lives in one place instead of scattered across your phone and three techs’ phones. Every message goes out under your business name. When somebody replies STOP, the system logs it and holds it, so you don’t blunder into texting them again six months later and land yourself in hot water. Your number stays your business number, so customers aren’t squinting at a text from a personal cell they can’t place. One flat price covers the office and the field, no per-seat charge. Founders pricing is $99/mo for your first three months, then $150/mo locked for the life of the account.

The TCPA is federal, and some states stack their own texting and calling rules on top of it, a few of them stricter. This is a plain-English overview, not legal advice. If you're planning a real marketing text campaign, an hour with a lawyer who knows your state's rules is money well spent.

Frequently asked questions

Is it legal to text my customers?

Yes, as long as they gave you their number and you're texting about their job or their business with you. Buying phone lists or blasting marketing to people who never opted in is where the TCPA gets you.

What is the TCPA and does it apply to small businesses?

The Telephone Consumer Protection Act is a federal law that governs business texts and calls. It applies to everyone, a one-truck operation included, not just big call centers, and penalties are charged per message.

Do I need consent to send appointment reminders by text?

A customer who books a job and hands you their cell number has effectively consented to texts about that job, including reminders and 'on my way' messages. Marketing promos need a clearer, separate opt-in.

What should I do when a customer replies STOP?

Stop texting them immediately, with no exceptions and no final message. The law requires the opt-out to be honored right away, so log it somewhere it won't get forgotten.
