Your website brings in new enquiries, but WhatsApp is often where the relationship actually continues. For many Indian businesses, customers already message on WhatsApp to ask prices, confirm orders and share UPI payment screenshots. Used thoughtfully, WhatsApp Business can turn those one-off chats into repeat customers.

This guide covers the marketing side and how it works with your website. Adding a chat button to your site is covered separately in WhatsApp on your business website.

WhatsApp Business app or the API?

There are two routes, and most small businesses should start with the first.

	WhatsApp Business app	WhatsApp Business Platform (API)
Best for	Shops, clinics, consultants and small teams replying personally	Stores and businesses sending automated or high-volume messages
Cost	The app itself is free	Meta charges for many message types, plus any provider fees; check current pricing
Automation	Greeting and away messages, quick replies	Order updates, reminders and integrations with your website or CRM
Key rules	Broadcasts only reach people who have saved your number	Opt-in required; messages sent more than 24 hours after the customer's last message must use pre-approved templates

Start with the app. Consider the API when you're sending the same messages by hand dozens of times a day, or you want your online store to send order and delivery updates automatically.

Catalogue: a shop window inside WhatsApp

The catalogue lets you list products or services with photos, prices and descriptions. Customers can browse without leaving the chat, and you can share an item in a couple of taps instead of typing the same details again.

• Mirror your website, don't replace it. Use the same product names, photos and prices, and add a link to each item's page on your site where the app allows, so customers can see full details and policies.
• Keep it current. An out-of-stock item or an old price causes awkward conversations. Update the catalogue whenever you update the website.
• Services work too. A salon can list packages, a tutor can list courses, a repair shop can list common jobs.

If you sell many products, an online store still handles orders, payments and GST invoices more cleanly; the catalogue should point customers there.

Labels: know who is who

Labels let you tag chats so you can find the right people later.

• By stage: new enquiry, quoted, paid, delivered, repeat customer
• By interest: the product range or service they asked about
• By consent: a label such as "Offers OK" for people who have agreed to hear about offers

That last label matters most. It keeps your broadcasts limited to people who actually asked for them.

Broadcast lists: offers without spamming

A broadcast list sends one message to many contacts, but each person receives it as a normal individual chat, and replies come only to you. Two rules shape how you use them:

1. Only people who have saved your number receive broadcasts. So encourage customers to save it, which is itself a sign of genuine interest.
2. People can block or report you. Irrelevant or frequent messages lead to blocks, and repeated reports can get a business account restricted.

Good broadcasts are occasional, relevant and useful:

• A festival offer for past customers, linked to a dedicated offer page on your website
• New stock or a fresh batch for customers who bought that category before
• Seasonal reminders, such as AC servicing before summer or admission dates for coaching classes
• A thank-you after a completed job, with a request for a review (see getting more Google reviews ethically)

Keep separate lists by interest, so a customer who bought sarees isn't sent kitchenware offers. Always give an easy way out, such as "Reply STOP if you'd rather not get these", and honour it straight away.

Status: gentle, everyday visibility

Status updates disappear after 24 hours and can be seen by contacts who have saved your number. For a local business, that's a free way to stay visible without messaging anyone directly.

• Today's fresh stock, specials or new arrivals
• Before-and-after photos from a recent job (with the customer's permission)
• A short tip related to your service, with a link to the full article on your website

Because people choose to view Status, it suits more frequent posts than you would ever send as broadcasts.

Opt-in and consent: do it properly

Consent is good manners and increasingly a legal expectation. India's Digital Personal Data Protection Act generally requires clear, specific consent for using personal data, and WhatsApp's own business policies expect you to have permission before sending marketing messages. The rules are being phased in, so check current requirements with your CA or lawyer.

Practical ways to collect opt-in:

• On website forms: an unticked checkbox such as "Send me offers and updates on WhatsApp", separate from the enquiry itself
• At checkout: the same optional checkbox on your online store
• In the chat: ask "Would you like us to share festival offers here now and then?" and label people who say yes
• In your shop: a QR code that opens a chat with a pre-filled message like "Yes, send me offers"

Mention WhatsApp in your privacy policy, and don't add numbers collected for one purpose (say, delivery) to marketing lists without asking. See privacy policy and cookie basics.

Connect WhatsApp and your website

WhatsApp works best as a loop with your website, not a separate channel:

1. Website to WhatsApp: product and service pages carry click-to-chat buttons with page-specific pre-filled messages, so you know what each person wants.
2. WhatsApp to website: broadcasts and Status link to a specific page (the offer, the product, the booking page), not just your homepage.
3. Track it: add UTM tags to links you share on WhatsApp so Google Analytics shows the visits and orders they bring; see UTM tags explained.
4. Make reordering easy: for things people buy again, such as groceries, cosmetics, pet food or printer supplies, send a reminder with a direct link to the product.

For online stores, automated order and shipping updates on WhatsApp (through the API) cut down "where is my order?" calls.

A simple weekly routine

• Label every new chat the same day
• Post a few Status updates a week
• Send broadcasts only when you have something genuinely useful to say
• Check which links got clicks and which messages got replies
• Remove anyone who asks to stop, immediately

Small, consistent habits beat occasional blasts, and they keep your number in customers' phones for the next purchase.
