How do I get regular customers to switch from phone calls to WhatsApp orders?

Tell regulars where they already are: the bill, the packaging, the counter and the phone. Give them one link or QR code that opens a chat.

• A wa.me link opens a chat in one tap, and ?text= adds a ready message such as I want to order.
• A Business app QR code does not expire unless you reset it or delete the account.
• Answer quickly the first time they try it, then keep the number the same.
• When a customer calls, say you can take their order faster on WhatsApp.
