Automate Review Requests by SMS After Every Job

How do you automate Google review requests by SMS?

Set a trigger in your CRM or field-service app: when a job is marked complete, send an SMS with your Google review link. No manual step needed.

The mechanism is simple. Your technician closes the job. The system fires a short text to the customer within minutes. The customer taps the link, leaves a review, done. What makes it powerful is that it happens after every single job — not just the ones you remembered to follow up on.

Why timing is the whole game

The right message sent two hours after the job beats the perfect message sent two days later.

Customer satisfaction peaks right after a good experience and fades fast. By the next morning, they’ve moved on to the next thing. A day later, the emotional memory that would have translated into a five-star review has dimmed. This is why businesses that ask immediately get a stream of reviews while businesses that batch their asks once a week get almost none — even when the work quality is identical.

For most service businesses — HVAC, roofing, landscaping, dental, med spa — the window is the same day the job closes. Within 30 minutes to two hours is the target.

What the sad path looks like versus the automated path

Most businesses intend to ask for reviews. Few actually do it consistently.

What should the SMS actually say?

Keep it under 160 characters: your name, a thank-you, the link, and an opt-out.

Here is a template that works:

“Hi [Name] — [Business], thank you for having us out today. If you have a moment, a quick Google review means a lot: [link]. Reply STOP to opt out.”

Four things in that message: who you are, a genuine thank-you, one ask with a link, and the required opt-out. Nothing more. No pressure language, no “it only takes 30 seconds,” no offer of anything in return — Google prohibits incentivized reviews, and that kind of language reads as desperate anyway.

If you want to send a follow-up for customers who didn’t open the first one, one reminder after a few days is fine. One. Sending the same request multiple times is what prompts the kind of reply you don’t want.

Compliance: what you must get right before you send

Every review request SMS must go to opted-in contacts, use a registered number, and include opt-out language.

This is not optional, and the review-request context does not create an exemption. Three requirements apply:

Own opted-in contacts only. These are customers who gave you permission to text them — existing customers, booking form opt-ins, service agreement sign-offs. Not purchased lists, not contacts scraped from somewhere else.

A2P 10DLC registration. Every business sending programmatic SMS in the US must register their number and use case with the carrier network. Unregistered messages get filtered before they reach anyone. If you haven’t done this yet, the step-by-step A2P 10DLC registration guide covers what you need and how long it takes.

Opt-out in every message. “Reply STOP to opt out” or equivalent — in every SMS, every time. Honor it immediately and permanently.

The broader strategy for how to get more Google reviews covers Google’s policy rules in full, including review gating and why you must offer all customers the same opportunity regardless of expected sentiment. The short version: ask everyone equally.

How the CRM trigger actually works

The trigger is a job-status event. When the record flips to “complete,” the automation runs.

Most field-service platforms — ServiceTitan, Jobber, Housecall Pro, GoHighLevel — have native workflow automation or a webhook that fires on status change. The review-request SMS is one of the simplest automations to wire up: status changes → check that the customer has a valid opted-in mobile number → send the template → log the send. If there’s no reply after a set window, send one follow-up. If they reply STOP at any point, remove them from future sends.

The variables you set: the delay (we recommend 30–60 minutes — long enough for them to be home, short enough that the experience is still fresh), the template, and the follow-up window. Once it’s running, it fires without anyone touching it.

What this is worth to your business

More consistent asking means more reviews. More reviews means better local search ranking.

Google’s local ranking factors weight review quantity and recency — a steady incoming stream matters more than a large stale total from years ago. A business that gets two or three new reviews every week will consistently outrank one that has twice as many reviews but hasn’t gotten a new one in months.

The math for your own business is straightforward. Take your weekly job count. Estimate what fraction would leave a review if asked immediately. Run that for 90 days. That’s roughly what consistent automation produces — not a promise, just the buyer’s own arithmetic on their own numbers.

What does it cost and how do you get started?

You can wire a basic SMS trigger yourself today if you have a CRM with workflow automation. The cost is time and a messaging platform subscription.

The automated version, managed end-to-end, is The Witness — our AI reviews and referrals agent. It handles the CRM trigger, the message templates, A2P 10DLC registration, opt-out plumbing, and the follow-up sequence. One agent, built for this job.

The Witness is $497/month plus a $1,500 one-time setup. That’s a single rung — not stacked fees. If you want reviews, follow-up, and speed-to-lead running together, that’s The Transformation, not multiple agent bills added up.

The lowest-risk place to start is still The Revival — free to begin, and you pay only on booked revenue. Reviews are a natural next layer once your pipeline is producing.
