QR Codes for Tradies: The Easiest Way to Get Google Reviews in 2026

There's a reason the tradies who consistently dominate Google search results all share one thing in common: they ask for reviews in person, at the job, before the customer's enthusiasm has a chance to fade.

And the tool that makes this dead simple? A QR code.

Not because QR codes are fancy technology. Because they eliminate the single biggest barrier to getting reviews: friction.

Why Friction Kills Review Rates

Ask yourself: have you ever told someone "just search for us on Google and leave a review"?

Here's what happens in their head:

1. Open Google — okay

2. Search for the business — what was the exact name again?

3. Find the right listing — is this the one?

4. Find the "Write a review" button — where is it?

5. Log into Google account — ugh, what's my password?

6. Type a review — what do I even say?

Most people abandon this by step 3. Not because they don't want to help you — because life gets in the way. They get a phone call. They start cooking dinner. They forget.

A QR code collapses this to two steps: scan, tap "Post." Nothing else required.

The QR Code on a Business Card: The Most Effective Review Tool for Tradies

The single highest-converting review tool for tradies isn't an email campaign, an SMS sequence, or a review management platform. It's a business card with a QR code on the back.

Here's why it works so well in the tradie context:

You're already handing them your card. It's a natural part of wrapping up a job. No extra step required.

The timing is perfect. The customer just watched you fix their plumbing, wire their switchboard, or build their deck. They're happy. Their goodwill is at its peak. Five minutes later they're thinking about dinner.

It feels personal. Getting a card from a tradie is different from getting an automated email three days later. It carries the weight of a face-to-face interaction.

It works on any phone. No app needed, no link to remember. Point camera, tap notification, done.

What to Put on the Card

Front: Your standard business card — name, trade, phone, website, logo.

Back: QR code linking directly to your Google review form. Add a simple line beneath it:

"Happy with the job? Scan to leave us a review — takes 30 seconds."

That's it. No cluttered design. No bullet points. Just the QR code and the ask.

How to Create Your QR Code

1. Go to your Google Business Profile (business.google.com)

2. Click "Ask for reviews" — Google gives you a short link directly to your review form

3. Go to any free QR code generator (qr-code-generator.com, qrcode-monkey.com)

4. Paste your review link and generate a high-resolution PNG

5. Send it to your printer or print shop — most can put it on business card templates

The QR code should be at least 2cm × 2cm to scan reliably on any phone. Bigger is better.

Other Places to Put Your Review QR Code

Business cards are the primary placement, but they're not the only one.

Leave-behind cards: A separate A6 card you leave at the job site after completion. These are especially effective for trades where you work inside someone's home — the customer finds it on the counter, scans it while they're still admiring the work.

Invoices and quotes: Add the QR code as a small footer element on your invoice. When the customer pays and reviews the invoice, they see the review prompt at exactly the right psychological moment.

Vehicle signage: A QR code on your ute or van catches people who saw your vehicle working in the neighbourhood. These cold reviews are lower conversion but zero effort — it's passive collection while you drive.

Counter displays: If you have a physical office, reception area, or shopfront, a small acrylic QR code stand on the counter captures walk-in customers.

Email signature: Add a small QR code image (or just the review link) to your email signature. Every invoice email, every quote follow-up — the link is right there.

The Ask Script That Goes With the QR Code

The QR code on its own has a decent conversion rate. Combined with a personal ask, it's dramatically higher.

The script is simple:

"Really glad it all came together well. I've got a card here — if you have a quick second to scan the code on the back, it would mean a lot to us. Takes about 30 seconds."

Hand over the card. Wait a beat. If they pull their phone out, you're golden. If they pocket it and say "I'll do it later," your follow-up SMS handles the rest.

What not to say:

• "Would you mind leaving us a 5-star review?" — You can't direct the rating. This sounds desperate and is bad practice.
• "Could you write us a Google review?" — Too much cognitive load. "Scan the code" is simpler and more actionable.
• "Only if you're completely satisfied" — This is review gating and violates Google policy.

The Follow-Up: When They Don't Scan on the Spot

Even with a perfect ask, some customers pocket the card and forget. That's fine — a follow-up doubles your conversion rate.

SMS (within 2–4 hours of finishing the job):

> "Hey [Name], [Your name] here from [Business]. Great to work with you today. If you get a chance, here's a link to leave us a quick Google review: [link]. Totally optional, but it genuinely helps. Cheers."

Warm, personal, low pressure. This converts at 15–25% on its own.

Email follow-up (if you don't have their mobile):

Subject: "Quick favour from [Business Name]"

Body: "Hi [Name], thanks for having us out. If you were happy with the job and have a moment, a quick Google review would really help us. Here's a direct link: [link]. No worries if not — just wanted to ask while it's fresh!"

QR Codes vs. Other Review Collection Methods

Here's how QR codes stack up against other common methods:

In-person QR code ask: Highest conversion (25–40% of people who scan complete a review). Requires your presence but builds the best reviews because the experience is fresh.

SMS follow-up with link: High conversion (15–25%). Slightly lower than in-person because it's less personal, but can be automated and scales easily.

Email follow-up: Medium conversion (5–15%). Lower because emails get ignored, but good for customers where you only have an email address.

Verbal ask without a card: Low conversion (5–10%). The customer intends to do it, then forgets. No physical reminder.

Generic "please review us" email blast: Very low conversion (1–3%). Impersonal, easy to ignore, no context.

The QR card system wins because it combines the highest-converting method (in-person ask) with the lowest-friction delivery mechanism (scan to open review form instantly).

What Makes a Great Tradie Review?

When customers scan your QR code and get to the Google review form, they often hesitate because they don't know what to write. This is where the experience you've already delivered matters most — but you can help.

On the landing page before the Google review form, you can prompt customers:

• "What service did we help you with?"
• "Was there anything specific that stood out?"
• "Would you recommend us to others?"

This gives them structure. The review they write will be richer, more specific, and more useful to future customers — and more valuable to your ranking because keyword-rich reviews signal relevance to Google.

This is exactly what Sentra's review flow does: customers scan your QR code, answer three quick questions, and the AI uses their answers to draft a genuine, specific review for them to edit and post. The QR code system meets a guided survey meets effortless posting.
