The short version: ask every customer, ask the moment the job is finished, ask by text with a link that opens the review box in one tap, and never pay for a review or screen out the unhappy ones. The rest is detail.
Most businesses that say they cannot get reviews are not asking. They are hoping. The ones that do ask are emailing three days late, with a link that takes four taps before the customer reaches a star.
Time the ask to the end of the job, not the end of the invoice
Goodwill has a half-life. It peaks the moment the tech shows the homeowner the thing works, and drops every hour after that. By the time your accounts email goes out on Thursday, the customer has forgotten your name and remembers the bill.
The pattern that works in the trades is two touches:
- The verbal ask, on site. The technician who did the work says it, in their own words, before they pack up. "If you were happy with this, would you mind leaving us a Google review? The office will text you the link in a minute." Ten seconds.
- The link, same hour. The office or the job software sends the SMS while the van is still on the street. The verbal ask is what gets the text opened; the text is what gets the review written. Neither works as well alone.
If your field team uses Jobber, Housecall Pro or ServiceTitan, the trigger already exists — fire the request on job status "complete", not on invoice paid. Payment can lag a week on commercial work, and the moment is long gone.
For HVAC, plumbing and roofing, this is among the highest-value things you can do in local SEO. Your competitors fit the same brands inside the same radius; review count and recency is much of what separates the three businesses in the map pack.
Longer sales cycles need a different trigger. A law firm asks at case resolution, a dental practice at the end of a treatment plan rather than after a routine cleaning, a restaurant at the table.
SMS or email: text wins, and here is why
No statistic needed. An SMS lands on the lock screen of a phone the customer is holding, already signed into a Google account. An email lands in the Promotions tab of an inbox they read on a laptop, possibly signed into a different Google account — and Google will not accept a review without one.
Email is not useless. It is right when you have no mobile number, when the buyer is a facilities manager who lives in Outlook, or when a large project deserves a longer note. It is also free, and at low volumes it is a sensible place to start.
Two things about US business texting people learn the hard way:
- A2P 10DLC registration is not optional. Texting from a 10-digit business number needs a registered brand and campaign, or the carriers filter your messages into nothing. Expect a one-off registration charge, a small monthly campaign fee, and several days for approval. Do not assume your platform has handled it.
- Consent matters. Capture the mobile number and permission to text about the job at booking. Messaging somebody who never gave you a number attracts TCPA claims, priced per message.
Keep the message short, sign it with the technician's first name, put the link last. "Hi Dana, Marcus here, thanks for having us out today. If you have 30 seconds, a Google review really helps a small shop like ours: [link]". No branding, no mangled tracking URL, no "we value your feedback".
Use the real link. In your Google Business Profile, the "Ask for reviews" button hands you a short g.page URL that opens the write-a-review box directly. Anything else adds taps, and every tap loses people. Test it from a phone before you automate anything: a wrong link or an unverified listing cannot be fixed by asking harder.
QR cards: cheap, and better than they sound
A printed card carrying that same review link as a QR code costs pennies and covers the customers whose phone number you never captured. It works on a counter, on the back of an invoice, in a takeaway bag, or handed over by the tech with the verbal ask.
- Point the code at the direct review link, never at your homepage. If they land on your site they will not go hunting.
- Print the ask in plain words next to it. A bare QR code under a logo gets scanned by nobody.
- Route the code through a URL you control, so changing the link never means reprinting.
- Cards are a backstop, not a system. They pick up whoever your automation missed; alone they produce a trickle.
For counter-service businesses — restaurants, salons, quick-service auto — the card at the till is genuinely your best channel: there is no other moment when the customer is happy, stationary and holding a phone.
What you may and may not incentivise
This is where businesses get their review profile wiped, and occasionally hear from a regulator.
Not allowed:
- Paying for reviews: cash, discounts, gift cards, prize draw entries, free product.
- Review gating: surveying customers first and sending the Google link only to the happy ones. Google's policy explicitly forbids selectively soliciting positive reviews, and the software that used to sell gating as a feature has largely dropped it.
- Reviews written by staff, family or your agency, and anything bought from a marketplace. The FTC rule on fake and deceptive reviews carries civil penalties per violation, so this is no longer a slap on the wrist.
- Offering somebody a refund in exchange for removing or editing a review.
Allowed:
- Asking. Every customer, every time. An ask is not an incentive.
- Paying your own staff for asks, not for reviews received. A bonus per ask logged in the job software produces asking. A bonus per five-star review produces fraud.
- Giving something to every customer regardless of whether they review or what they say. A discount on the next service for everyone is marketing; a discount for reviewers is a bribe.
- One reminder a few days later. Three is harassment.
Reply to all of them, and reply like a person
Replies are public and permanent, and read far more often by the next prospect than by the reviewer.
On the good ones, two lines is enough: use the first name and mention the actual work. "Glad the condenser is running right again ahead of the summer" tells a stranger what you do. Pasting "Thanks for the 5 stars" forty times looks like what it is.
The bad one
Answer it the same day, in public, once. The structure that holds up:
- Thank them for the feedback, by name if you have it.
- Acknowledge the specific problem in one sentence, without excuses.
- Say what you have changed, or what you are doing about it.
- Give a named person and a direct line, and move it offline.
Do not argue the facts, do not mention what they paid, do not imply they are lying. A defensive reply turns one bad review into a reason not to call you.
One hard rule for regulated trades: if you are a dental practice or a medical clinic, do not confirm that the reviewer was a patient and do not correct their account of their treatment. Practices have been fined for precisely that. "We take all concerns seriously and would like to speak with you, please call our office manager on X" is the whole reply.
You can flag a review that breaks Google's policies: spam, a competitor, profanity, a conflict of interest, a customer of another business. You cannot flag one for being unfair. Removal is uncertain, so plan on out-weighing rather than deleting.
Do that arithmetic before you panic. Twenty reviews averaging 4.2 is 84 stars. Add twelve genuine five-star reviews and you have 144 stars across 32 reviews, which is 4.5. At 200 reviews, one angry customer barely moves the number at all, which is the real argument for building volume before you need it.
What it costs to run this properly
Bands, because it depends on your job volume and what software you already own.
| Approach | Typical monthly cost | What moves it |
|---|---|---|
| Manual, from a shared phone | $0 | Stops the first busy week. Workable under roughly 20 jobs a month. |
| Built into your field service software or PMS | $0-$50 add-on | Often already included. Check before buying anything else. |
| Dedicated review and messaging platform | Roughly $150-$500 | Locations, whether webchat and payments are bundled, contract length. |
| Build-your-own stack (GoHighLevel, Twilio) | Roughly $100-$300 plus per-message fees | Message volume, depth of automation, who maintains it. |
| Agency-managed reputation programme | From $200, always a minimum | Locations, platforms beyond Google, whether replies are written for you. |
Single location, modest volume: buy nothing. Switch on the review request in the software you already pay for, print QR cards, train the verbal ask. Most of the value for almost none of the money.
Paying somebody makes sense with multiple locations or crews, when replies must stay consistent, when reviews need syndicating beyond Google, or when nobody in the building will own it. That is what our reputation management work covers; the automation we most often build on GoHighLevel, because it keeps the request, the follow-up and the lead record in one place. Our pricing starts at $200 and moves with locations and scope.
Reviews are also part of what AI assistants repeat back when asked for a recommendation, which is the second reason to keep them recent and answered, and where this overlaps with generative engine optimisation.
