WhatsApp QR Codes for Small Business

Where to put one

The code works best where a customer is already deciding whether to get in touch. A shop window after closing time. A table tent in a restaurant. A label on a delivery box. A stand at a trade fair. A property sign outside a building.

• Shop windows — reachable when you are closed
• Menus and tables — orders and questions without flagging down staff
• Packaging — support requests that arrive with order context
• Business cards — one-tap alternative to typing your number
• Property and vehicle signage — inquiries from the pavement

Write the pre-filled message carefully

The pre-filled message is the most under-used part of a chat code. An empty input box makes people hesitate; a first line already written makes them tap send. It also tells you where the scan came from.

Keep it short, specific to the placement, and phrased from the customer's side. Vary it by location so the incoming message identifies its own source.

• Window sign: "Hi, I saw your window display and wanted to ask about…"
• Menu: "Table 6 — I'd like to order…"
• Packaging: "Hi, I have a question about my order"
• Property sign: "Hi, I'm asking about the flat on Rue Mohammed V"

Printing one that scans

Most codes that fail in the wild fail for physical reasons, not digital ones. Print at least three centimetres across for a handheld scan and much larger for a window or poster read from a distance. Leave the white margin around the code intact — it is part of the pattern. Keep strong contrast and avoid printing over photographs.

Test the printed version, not just the screen version, before you order a hundred copies. Check it in the light conditions where it will live: a glossy laminate under a spotlight can be unreadable even though the file is perfect.

Knowing whether it works

Without analytics on a printed code, the pre-filled message is your measurement. Different wording per location tells you which placements produce conversations. Review after a few weeks, move the codes that produce nothing, and print more of the ones that do.
