Small shops and freelancers often want a WhatsApp click-to-chat QR on a counter sticker, menu, or business card. Hosted QR SaaS products charge ~$49/month for static codes that never change — you can generate the same thing locally in seconds.
The link format
WhatsApp click-to-chat URLs look like:
https://wa.me/15551234567
Optional pre-filled message:
https://wa.me/15551234567?text=Hi%2C%20I%27d%20like%20to%20order
Use your country code without + or leading zeros. Encode the full URL as the QR payload — scanners open WhatsApp directly.

Print tips
- Minimum ~2 cm square for reliable phone scans
- Leave quiet zone (white margin) around the code
- Matte laminate reduces glare on glossy stickers
- Put a short label: "Scan to WhatsApp us"
Why not a monthly QR subscription?
Static WhatsApp links do not need analytics dashboards or dynamic redirects. A PNG you control is enough for most cafés, salons, and market stalls. Pay once for batch tooling if you need volume; skip recurring fees for a link that never changes.
