Enter the home once. You get a feedback link and a QR code for that specific house. Print the QR, set it at the door, and anyone who scans it lands right on the form.
This is exactly how the top of the buyer form will look. Leave the photo blank to keep the illustration. Your photo shows on the live form once your site is connected.
When you open this tool from your live web address, this box fills itself in with that address, so every QR you make here works the moment you print it. Change it only if your feedback page lives somewhere else.
