WhatsApp Business API in Chennai

A QR code on the bill is your best marketing

Print a QR code on the bill and the counter: "Scan to get new arrivals on WhatsApp." The customer scans, a WhatsApp chat opens with your business, and they send the prefilled message.

That one message is an opt-in and it opens a conversation. The contact is now yours — on your verified business number, not a salesman's phone.

A busy shop collects hundreds of these in a festival week. By January you have a list of real customers who asked to hear from you.

Who uses it in Chennai

• Saree and jewellery shops on Ranganathan Street and Usman Road — new collections and wedding-season offers to past buyers.
• Parrys and George Town wholesalers — rates and stock to retailers across Tamil Nadu.
• Ritchie Street electronics sellers — stock updates to repair shops and repeat buyers.
• Clinics and diagnostic centres in Anna Nagar, Adyar and Nungambakkam — reminders and report-ready notices.
• IT firms and startups along OMR — OTPs and order updates from their own apps.
• Factories in Ambattur, Guindy and Sriperumbudur — dispatch messages to dealers.

Tamil first, English where it helps

Create each important template in Tamil and English. A customer from Kanchipuram who scanned your QR may read Tamil; a customer from OMR may read English. Tag the language when the contact joins, and send the right version.

Keep the Tamil simple and spoken, not formal. A message that sounds like the shop assistant who served them gets a reply.

Bringing the Deepavali customer back in Pongal

The list you built in October is worth most in January. Send a Pongal collection message to the Deepavali buyers. Send the wedding season list in March to customers who bought bridal pieces.

Keep it to a few messages a season. On Pro, marketing cooldown keeps anyone from getting too many. A customer who replies opens a chat, and your staff answer from the shared inbox with the photos they ask for.

Making the QR work at a busy counter

A QR code only works if someone mentions it. Give the billing staff one line to say: "Scan this and we will send you new arrivals first." It takes five seconds while the bill prints.

Set the prefilled message to something clear, like "Yes, send me new arrivals". That makes the opt-in obvious in your inbox.

The first reply from your side should come at once, from the auto-reply bot on Growth: a thank-you in Tamil and English, and one photo of this week's collection. The customer is still in the shop, and sometimes buys one more thing.

Put the same QR on your carry bag, your visiting card and your Instagram bio. Every one of them becomes a way into the list.

What the platform does not include

It does not print the QR for you on your bill — that is your billing software or printer. There is no catalogue or cart inside WhatsApp and no payment in the chat; offers link to your store or bring people to the shop. Messages go on WhatsApp only, contacts are kept in lists, and the bot is rule-based.

The verified badge is Meta's call. Meta's messaging tiers apply to every business in Chennai.
