The best moment to ask for a review is the handover: the new boiler is running, the bathroom is spotless, the customer is happy. With a QR code on the invoice or delivery note, one scan takes them straight to your business's review form, without having to search for it first.
Why reviews win jobs for trades businesses
Anyone looking for a roofer or an electrician compares the stars and the number of reviews on Google Maps first and only then looks at the website. A steady flow of new reviews also helps in local search: businesses with recent feedback show up more often in the map results when someone types “plumber near me”.
Happy customers still rarely leave a review on their own. It is usually not a lack of goodwill but the effort: they would have to find your business on Google first and then look for the right button. The direct link opens the review window straight away.
Where the QR code works best in the trades
On the invoice or delivery note, right next to your thanks for the job. On the handover or acceptance report. As a sticker on the company van, on the workshop counter where customers collect their car, or in your showroom. On the back of the business card you leave behind with a quote.
Send the link itself by email or WhatsApp, ideally together with a photo of the finished work. It reminds the customer of the result and makes the review more specific.
How to find your Place ID
The Place ID is the reference number Google uses for your business. You can find it with Google's free Place ID Finder: type in your business name, click the right entry on the map and copy the ID shown. It usually starts with “ChIJ”.
From that ID the tool builds a link that opens the review form directly. It works on phones and computers.
Asking for reviews fairly
Ask every customer, not just the ones where everything went smoothly. Discounts or vouchers in return for reviews, reviews from your own staff and bought reviews break Google's policies and count as unfair competition. Instead, reply briefly and factually to every review, including critical ones: readers pay close attention to how a business handles complaints.
