QR Codes for Review Collection: Where to Put Them and How to Design Them (2026)
The conversion data on QR placements: receipts, table tents, business cards, signs, packaging, and shop windows. Plus the design specs that make a QR scannable from 1 meter away and the print-ready setup that takes 10 minutes.
A QR code stuck on a receipt has produced more Google reviews per dollar of spend than any other tactic we have seen across small businesses since 2022. The reason is uncomfortably simple: the customer is looking at the receipt anyway, the phone is already in hand for payment, and the experience is fresh. Three friction points eliminated at once.
This piece covers eight QR placements, ranked by conversion data, plus the design specs that make a QR scannable in real-world conditions and the 10-minute setup that turns "I should print one of those" into a working review collector.
The conversion data
Across our analysis of small business case studies and the published research from BrightLocal (2024) and the Spiegel Research Center (2017), QR placements rank roughly like this for review collection:
| Placement | Typical Conversion | Best For |
|---|---|---|
| Receipt (printed) | 8 to 12 percent | Restaurants, cafés, retail |
| Receipt (digital, in email) | 4 to 8 percent | Any business with email receipts |
| Business card | 6 to 10 percent | Service businesses, B2B |
| Counter sign at checkout | 3 to 5 percent | Retail, salons, clinics |
| Table tent | 1 to 3 percent | Restaurants only, low ROI |
| Packaging insert | 5 to 9 percent | E-commerce, products with unboxing |
| Wall poster | 0.5 to 2 percent | Waiting rooms, hotel lobbies |
| Shop window decal | 0.3 to 1 percent | Walk-by traffic |
Volume matters too. A receipt at 10 percent conversion across 200 daily transactions produces 20 reviews per day in theory and 5 in practice (after deduping for repeat customers and accounting for ones who never get around to it). A wall poster at 1 percent conversion across 500 daily impressions produces 5 in theory and 1 to 2 in practice. The receipt wins on both rate and volume.
Placement 1: The printed receipt
The single highest-converting QR placement.
Where on the receipt: Bottom third, below the total but above any company tagline. Customers visually scan top-to-bottom; the QR catches their eye after they confirm the amount and before they fold the paper.
Copy that goes with it: Keep it short.
Loved your visit? Leave a quick review: [QR CODE] Takes 30 seconds.
Three lines. Do not write a paragraph. Do not include a generic "thank you for your business." Do not put it in three languages on the same receipt.
Print specs:
- QR size: minimum 2 cm by 2 cm
- Black ink on white thermal paper
- Quiet zone (white margin) of at least 4 modules around the QR (this is what most receipt printers get wrong)
Setup with Review Manager: Generate the QR via the dashboard, download the PNG, paste it into your POS receipt template (most modern POS systems support a logo or footer image). Done in 10 minutes total.
Placement 2: The digital receipt
If your POS sends digital receipts via email or SMS, the same QR (and link) goes in there. Conversion is 4 to 8 percent. Lower than printed because the customer is more likely to skim and dismiss, but higher reach because more customers actually receive digital receipts than re-read printed ones.
Use the same link as your printed receipt. One link, multiple surfaces. The Review Manager dashboard tracks where each tap came from if you set up UTM parameters.
Placement 3: The business card
The most under-used QR placement we see in the wild.
A QR on the back of a business card converts 6 to 10 percent of the customers who keep the card and scan it. That number is lower than receipt because volume is lower (most cards get tossed), but quality is higher. The customers who keep the card and scan it a week later are loyal. Their reviews tend to be longer, more substantive, and feature better keywords (which has secondary SEO benefits).
Layout: Use the back of the card. Print one line above the QR: "Loved working with us? Quick review here." Center the QR vertically, with the line above and a small business name below.
Print specs:
- QR size: 2.5 cm by 2.5 cm minimum (cards are scanned at very close range)
- Single-color print is fine; the QR pattern itself stays black
We wrote a longer piece on this in the business card review link strategy.
Placement 4: The counter sign at checkout
A small sign next to the cash register or payment terminal. Conversion of 3 to 5 percent in retail and salon contexts.
Format: Acrylic or laminated card, A6 size (10 cm by 15 cm). Counter-top, near the payment terminal. The phone is already out for payment; scanning is one extra movement.
Copy: "Quick favor? Leave a review while you wait. [QR CODE] Takes 30 seconds."
Avoid: Anything that mentions stars or asks for a specific rating. Phrases like "leave a 5-star review" violate FTC rules around solicited positive reviews.
Placement 5: The table tent (only if you must)
The classic restaurant placement, and the lowest-converting of the printed options.
Conversion of 1 to 3 percent because customers do not interact with the table tent unless they are bored. By the time they are bored at the table, they are probably not in the mood to leave a review.
If you do it: make it small (A5 standing format), put it on the corner of the table where it is not in the way, and use copy that hooks emotion ("Did our team make your day?") rather than transaction ("Please leave a review").
We see better results when restaurants drop the table tent and double down on the receipt QR instead.
Placement 6: The packaging insert
For e-commerce and product-based businesses. A printed card slipped into the package alongside the product.
Conversion of 5 to 9 percent because the unboxing moment is emotionally peak. The customer just opened a package they were waiting for; they are predisposed to good feelings about you.
Format: A6 card, single-sided, printed on slightly heavier stock so it does not feel like junk mail.
Copy:
Did your
{productCategory}arrive OK? [QR CODE] Quick review takes 30 seconds and helps us a lot.{OwnerFirstName}
Sign it with the owner's first name; impersonal versions ("the {Brand} team") convert worse.
Placement 7: Wall poster (waiting room or hotel lobby)
For dental practices, doctors, salons, and hotel lobbies where customers spend several minutes waiting.
Conversion of 0.5 to 2 percent. Lower than counter sign because the wall poster is a passive surface; the customer has to choose to engage.
Format: A3 minimum (30 cm by 42 cm). Eye level. Near the seating area.
QR size: 12 to 15 cm by 12 cm (to be scannable from 1 to 1.5 meters).
Copy: Use a question, not a statement. "Did we make your visit easy?" outperforms "Please leave us a review" by roughly 30 percent.
Placement 8: Shop window decal
For storefronts with high foot traffic. Captures the rare passing customer who wants to leave a review but does not want to come inside again.
Conversion is the lowest of any placement (0.3 to 1 percent), but the cost is also near zero (a single vinyl decal, 30 to 60 EUR). The math works out for businesses with very high foot traffic; it does not for low-traffic locations.
QR size: 15 cm by 15 cm minimum, since customers will scan from 2 to 3 meters.
Design specs that matter
Most QR codes in small business contexts fail because of preventable design errors. The four most common:
1. The QR is too small. A common mistake on packaging inserts and counter signs. The minimum scannable size is 2 cm; smaller QRs fail intermittently across phone models, especially older Android devices.
2. No quiet zone. The QR pattern needs at least 4 modules of white space around it. When the QR is printed flush against a colored background or another graphic, scanning fails 20 to 40 percent of the time.
3. Low contrast. Black on white is the gold standard. Colored QRs (brand-colored on white background) work but reduce scan reliability by 5 to 15 percent. Reverse-out QRs (white on black) work in theory but fail on most phone scanners.
4. The QR is wrapped around a logo too aggressively. Modern QR generators support a logo overlay in the center. The logo should occupy no more than 25 percent of the QR area. Bigger overlays trip the error correction and the QR fails to scan.
How Review Manager handles QR generation
You can generate a QR for a Google review URL with any free QR generator on the internet. Most owners start there, and most run into one of two problems within 30 days.
Problem 1: The QR points directly to the long Google review URL. The URL works, but the customer's phone might show a security warning ("This link goes to googlemaps.com/...") that customers ignore in 80 percent of cases and abandon in 20 percent. The 20 percent loss compounds.
Problem 2: The Google review URL changes when Google updates its profile system. Profiles get re-indexed, URLs get rewritten, and the QR you printed a year ago suddenly leads to a 404 page. We have seen restaurants discover this after printing 5,000 receipts with a now-dead QR.
What Review Manager does differently:
- Generates a short branded URL like
r.review-manager.org/your-business-namethat you fully control - The URL stays stable forever; if Google changes its review form URL, Review Manager updates the destination behind the scenes and your printed QRs keep working
- The QR generator outputs PNG, SVG, and print-ready PDF in one click
- A logo overlay option lets you put your brand mark in the center without breaking scannability
- The landing page behind the QR auto-routes 5-star ratings straight to Google and 1-to-3-star ratings into a private feedback form, so issues get caught privately
The setup is genuinely under 10 minutes. Sign up for the free tier, paste your Google Business Profile URL, click Generate QR, download. Print.
The free tier supports one location indefinitely. Pro at 5.99 EUR per month adds custom branding for the landing page (your logo, colors, welcome message). Business at 19.99 EUR per month supports up to 5 separate QRs for multi-location or per-staff-member tracking.
