WhatsApp for restaurants and cafés in India

By Abhishek Chandra · Updated 20 October 2026 · 6 min read

TL;DR: For a restaurant, WhatsApp does three jobs: take direct orders without an aggregator's commission, confirm reservations, and bring past diners back. Order and reservation messages are cheap utility messages (around ₹0.115 each, billed every time since 1 October 2026); offers are marketing messages at around ₹0.86. The hard part is not cost — it is building your own opted-in customer list, because aggregator customers are not yours to message.

Why restaurants use WhatsApp

Aggregator apps bring discovery, but they keep the customer relationship and a commission on every order. A diner who orders from you three times a month through an app is, as far as you can tell, a stranger. WhatsApp is where you can know your regulars by name, take their next order directly, and tell them about the new menu — in the app they already open fifty times a day.

What restaurants actually run

Direct ordering

A WhatsApp catalog of the menu, the order taken in chat, and a UPI payment link to settle it. The customer starts the conversation — from a QR code on the table, the bill or the parcel — but business replies are subject to Meta pricing: the first 1,000 service messages per phone number each month are free, then charges apply. Keep the menu short and current; an item that is sold out should be out of the catalog.

Order confirmations and delivery updates

"Order received", "out for delivery", "delivered" — utility messages that stop the "where is my food?" calls. Utility messages are billed per delivered message, even inside the service window.

Reservations

A booking confirmed in writing, and a reminder on the day with a button to confirm or cancel. A cancellation you hear about at 5 pm is a table you can still give to a walk-in.

Bringing diners back

A "today's special" or weekend offer to customers who opted in. This is marketing, so it costs more and needs consent — and it works best segmented: the lunch crowd and the Friday-dinner families want different messages.

Festival and event specials

Diwali sweets boxes, Navratri thalis, match-night combos. Scheduled ahead, sent once, to the people most likely to care.

Feedback

A short message the day after a visit or delivery. The unhappy customer tells you instead of the review site, and the happy one gets a link to leave a review.

What it costs

Since 1 October 2026 Meta bills every delivered message. In India, marketing messages — offers, specials, new-menu news — cost roughly ₹0.86 each; utility messages — order and reservation updates — roughly ₹0.115, billed every time since 1 October 2026, with no free window.

So a weekly offer to 1,000 regulars is about ₹863.10 a week in Meta fees, while order updates are utility messages billed per delivery. The pricing breakdown covers every category, and the cost calculator works out your own numbers.

Consent and building your own list

Aggregator customers are not your list. Swiggy and Zomato do not share customer numbers, and messaging someone who never opted in is how numbers get reported and restricted.
Let the customer message first. A QR code on the table, bill, menu card or parcel sticker that opens a chat with a prefilled "Hi" is a clear way to start and record consent. The first 1,000 service replies per business phone number each month are free; later replies are billed.
Ask separately for offers. Someone who ordered once agreed to receive updates about that order, not your weekly specials. A one-tap "Send me offers" button is enough.
Make stopping easy, and respect it. A diner who opts out of offers can still order from you.

This describes common practice, not legal advice.

Frequently asked questions

How much does it cost a restaurant to send a WhatsApp offer?

An offer or a menu announcement is a marketing message, billed by Meta at roughly ₹0.86 per delivered message in India. A weekend offer to 1,000 opted-in regulars costs about ₹863 in Meta fees. Order confirmations and delivery updates are utility messages at roughly ₹0.115 per delivered message, billed since 1 October 2026 whether or not the customer messaged you first.

Can I message customers who ordered through Zomato or Swiggy?

Generally no. Aggregators do not hand you the customer's phone number, and you need the customer's own consent to message them. The practical route is to build your own list: a QR code on the bill or the parcel that opens a WhatsApp chat, where the customer messages you first and can opt in to offers.

Can customers order food directly on WhatsApp?

Yes. You can share a WhatsApp catalog of your menu, take the order in the chat, send a UPI payment link, and follow up with confirmation and delivery updates. The first 1,000 service replies per business phone number each month are free; later service replies are charged at the applicable rate. Customer messages themselves are free.

How often can a restaurant send offers on WhatsApp?

There is no fixed legal number, but frequency is what gets a business blocked. Meta also limits how many marketing messages a person receives from businesses, so extra sends may simply not deliver. Most restaurants do best with one well-timed message a week or less, plus festival specials.
