Where to Put QR Codes for Google Reviews (Top 3 Placements for Home Services)

Where are the best places to put QR codes to get more reviews for your home service company? I get asked this a lot, because everyone’s printing a QR code on marketing materials and hoping it turns into more Google reviews.

In this blog, I’ll share three placements that actually do the work, instead of just taking up space. Placement matters, but it’s not the only factor. Your QR code needs the right context, the right timing, and a simple call to action so happy customers take the next step and leave Google reviews.

Key Takeaways

• A QR code only works when it’s paired with a written call to action that tells people what to do next. If the code sits there with no instructions, customers scan less, and reviews stay flat.
• The best placements are physical, easy to scan with a smartphone, and show up at the right moment in the customer’s experience. When customers scan, you want them to land directly on your Google review link so the process feels seamless and leads to more positive reviews.
• My top three placements are: a technician business card with the Google review QR code on the back, the bottom of paper invoices when that applies to your industry, and a thank-you postcard follow-up. 
• Avoid putting QR codes in digital formats that customers view on their phone, because it kills quick access and wastes space.

Before Placement: What Makes a QR Code Actually Convert for More Google Reviews

Placement alone isn’t the magic. The QR code design, the instruction beside it, and the moment it shows up in the customer journey are what drive conversions.

At a minimum, you need written copy next to the code. That can be plain, direct, or a little playful, but it must be clear. Here are examples that work:

• “Scan this link, leave us a review.”
• “How did we do? Do we deserve your review? Scan this link.”

You can customize the tone, add a logo, or get cheeky with it, but keep it simple.

In home services, customers are not going to hunt through your website, search your company name, or visit five pages to find the review link. Your job is to make it obvious and easy, so customers leave feedback in the moment.

If you need the official method to create this correctly, Google walks you through it. Use the steps from Google Business Profile Help on how to create a link or QR code to request reviews so your business listing points to the right place and your business profile can collect public customer reviews without friction.

Placement #1 (Best): Technician Business Card (QR on the Back) for a Google Review QR Code

This one might seem obvious, but it’s the best use of a Google review QR code in the field. 

Your technician should have a business card with their name, other details, and contact info on the front, and the Google review QR on the back.

The reason it works is timing and convenience. The card is a physical leave-behind that customers can keep on the counter, in a drawer, or near the receipt and paperwork. When the customer makes time to respond later, the code is right there.

Here’s how it should work in your process:

• The tech asks for the review at the end of the service call.
• Your follow-ups support the ask, so you get more reviews consistently.
• The business card gives customers quick access to scan and leave a review without searching.

This removes friction because customers do not need to remember your Google business name, open a browser, and search for the right page. They just scan, land on the review link, and write the review while the experience is still fresh.

If you want the best results, make sure the QR code points directly to your Google review link, not your homepage. Your business profile is the destination, and that’s where ratings, average rating, and reviews influence ranking in maps and local search.

A practical tip is to test the card before you print thousands. Use a QR code generator, generate QR code options, and validate the URL in the URL field so it opens the right business profile every time. If you create a Google review QR code that breaks, you miss the full potential of that placement.

Placement #2 (Situational): Bottom of Your Invoices for Google Reviews

This placement is situational, and it depends on how your company handles invoices. If you still send paper invoices, or you use invoices as a follow-up tool, the bottom of the invoice can be an excellent way to prompt Google reviews.

The timing is what makes it work. Once the customer finishes the invoice, they’re thinking about the service, the outcome, and whether the experience matched expectations. That’s often the moment they’re willing to leave reviews, especially if the job is complete and they are satisfied.

To make it convert, keep it straightforward:

• Place the QR code at the bottom where the eye naturally goes.
• Add a short CTA beside it like “Scan to leave Google reviews.”
• Make sure it links to the Google review link, not a generic website page.

Do not confuse this with digital invoices. If customers view the invoice on their smartphone, they can’t scan a QR code that’s on the same screen. In that digital format, use a clickable link instead of code.

If you want to build this into a bigger review system, we cover the overview in Digital Harvest’s review marketing automation page. The goal is more Google reviews that support local trust, not a one-time spike that you can’t manage.

Also, invoices are part of operations, so keep the design clean. The QR code should not compete with pricing, totals, or service notes. It should sit below the line items, near the receipts section, so it feels like a natural next step.

Placement #3 (Differentiator): Thank-You Postcard Follow-Up (QR + Review CTA) to Leave Google Reviews

If you want something that sets you apart from competitors, this is it. Send a thank-you postcard follow-up with a Google review QR code and a simple review CTA.

For high-volume businesses, you can automate this so it scales. You do not need to handwrite every postcard. The key is that it’s physical, it arrives after delivery of the service, and it feels intentional.

Here’s what to send:

• A written thank-you postcard.
• A QR code that goes directly to your review link.
• A short message that makes the next step obvious.

Use this as a model copy, because it matches the tone and timing that works:

“Would you recommend our services? If yes, scan this code, leave us a review. Your review means a lot to our local business.”

This placement works because it gives customers another moment to act. Some people forget to leave reviews right after the visit, even when they’re happy customers. A postcard shows up later, and it’s an easy reminder that prompts action.

It also performs well for local businesses that depend on maps visibility. Reviews and ratings influence whether nearby customers choose you when they search, especially in a competitive city. When customers scan the code, you capture feedback in the place that supports your business profile the most.

If you offer product packaging, memberships, or a subscription service alongside home services, the postcard can complement that, too. It reinforces brand trust, keeps you top of mind after purchase, and helps you collect more positive reviews over time.

Where Not to Put QR Codes So They Don’t Just Take Up Space and Hurt Google Reviews

Here’s the common mistake. People put QR codes into digital formats, and they’re not really thinking about it.

A QR code in an email follow-up does not help you in most cases. The customer sees it on the same phone they would use to scan it, so the code can’t be used. The same issue happens with a QR code in a digital invoice, especially if it’s viewed on a smartphone.

Technically, it could work if a customer is on a computer and scans with their phone. In real life, it’s not practical, and it’s not likely. That’s why these placements fail, and why they end up as print clutter instead of a powerful tool.

Use the right format for the right channel:

• Physical formats: QR code + CTA.
• Digital formats: clickable Google review link, not a code.

If you want customers' scan behavior to increase, reduce steps. Do not make them open an email, take a screenshot, download it, then try to scan. That is too much friction, and you lose reviews.

Save the space in digital formats for something that converts better, like a direct link, a short sentence, and a reminder of what the review helps. You can also include a quick note that public customer reviews help local businesses stand out in search results and maps.

Make the 3 Placements Work Together (Process + Follow-Ups + Automation) for More Google Reviews

The QR code is not the whole system. It’s the friction-remover that supports your process.

Here’s what I want you to do. Follow your review process in the field, then let follow-ups do the heavy lifting—check this article on how to recover a Google review after the job is already done to ensure no opportunity for feedback slips through the cracks. The QR code placements give customers quick access at physical moments when they can actually scan.

A simple sequencing that works:

• Business card: immediate option right after service, when the customer is face-to-face with your tech.
• Invoice bottom: a timing moment when they’re reviewing charges, service notes, and receipts.
• Thank-you postcard: a differentiator that arrives later and prompts action from customers who forgot.

These placements work together because they show up at different points in the customer journey. They are recommended because they actually work, and they are not just taking up space on your marketing materials.

If you want to improve outcomes, make sure you can respond to and manage the reviews you receive. When you get positive reviews, reply to them. When you get feedback that points to a fix, use it as insights to improve service.

Also, keep the destination consistent. Point everything to your business profile so your Google reviews build trust where consumers are already searching. For additional guidance, Google outlines best practices on how to get more reviews.

Lock In the 3 Placements and Skip the Digital QR Mistakes 

If you want QR codes that actually produce reviews, keep it simple. Every QR code needs a written CTA, and it needs to live in places where people can actually scan it.

Use the three placements that work: technician business cards with the Google review QR code on the back, the bottom of paper invoices when that fits your industry, and a thank-you postcard follow-up. Avoid QR codes in digital formats on mobile, and use a clickable Google review link instead.

Frequently Asked Questions

Where should I put a QR code to get more Google reviews?

The best places to put a Google review QR code are physical touchpoints where customers can easily scan with their smartphone. For home services, that means a technician business card, the bottom of paper invoices or receipts, and a thank-you postcard follow-up. 

These placements show up at the right moment in the customer journey and provide quick access to your Google review link, which leads to more reviews and a higher average rating on your business profile

What should a QR code say to get customers to actually leave a review?

A QR code must always include a clear written call to action. Simple language works best, such as “Scan this code to leave a Google review” or “How did we do? Scan to leave feedback.” The goal is to remove confusion and tell customers exactly what happens after they scan. 

When customers know they’re going straight to leave Google reviews, scan rates increase and the process feels seamless.

Should I put a Google review QR code on my invoice?

Yes, but only if the invoice is something the customer can physically scan, like a paper invoice or printed receipt. Placing the Google review QR at the bottom works well because the customer is already focused on the service and outcome. 

Always pair it with a short CTA and link it directly to your business profile review link so customers can leave reviews without searching.

Is it a bad idea to put a QR code in an email review request?

In most cases, yes. If customers view the email on their smartphone, they can’t scan a QR code that’s on the same screen. That adds friction and reduces reviews. For digital formats like email or online invoices, use a clickable Google review link instead. QR codes perform best in print, not digital follow-ups.

How do I create a QR code that links directly to my Google reviews page?

Start inside your Google Business Profile and generate your Google review link. From there, use a QR code generator, paste the url into the url field, and generate the code. Test it on multiple devices to confirm it opens the correct business profile. 

Once confirmed, print it on your marketing materials so customers can scan, leave a review, and help you collect more positive reviews consistently.
