How to take restaurant orders on WhatsApp
The short version
- Customers already message restaurants on WhatsApp. The question is only whether anyone answers in time.
- The free WhatsApp Business app works for a quiet takeaway. It breaks the moment two people need to answer at once.
- Automation is worth it when the phone rings out during service, or when you are paying someone mainly to take orders.
- Whatever you use, read the order back before confirming it. Most wrong orders are heard wrong, not cooked wrong.
Why WhatsApp, and why now
In both the UK and India, WhatsApp is the app people already have open. A customer who wants a takeaway on a Friday night will message the number on your Instagram or your Google listing, and they expect a reply in minutes. If they do not get one, they order from the restaurant down the road. They do not ring back. That is the whole case for WhatsApp ordering. It is not a new sales channel so much as a leak you are already paying for. The orders are arriving; the only question is how many of them get answered while your team is busy with the people in front of them.
Option one: answer by hand
The simplest version is a phone with WhatsApp on it and a person reading the messages. It costs nothing and it works - for a quiet restaurant, in quiet hours. It fails in the exact hours you need it. The messages arrive at the same time as the walk-ins and the phone calls, and the person holding the phone is also plating or on the till. Orders get typed out from memory, modifications get missed, and nobody has the address written down properly. The customer waits twenty minutes for a reply that says "sorry, what did you want?"
Option two: the free WhatsApp Business app
The WhatsApp Business app is free and most restaurants should set it up regardless of what else they do. It gives you a business profile with your hours and address, a catalogue you can use as a menu, quick replies for the messages you send fifty times a day, and automatic greeting and away messages. Its limits are the same as a personal phone: one number, one main device, and replies still typed by a person. The catalogue is a list of items, not an ordering system - the customer still has to type what they want, and someone still has to add it up. It does not take payment, and it cannot answer at all when nobody is holding the phone. It is the right choice if you take a handful of orders a day and someone can always reach the phone. It is the wrong choice if service is busy enough that the phone already rings out.
- Set the business profile properly: hours, address, a link to your menu and your delivery area.
- Use the catalogue as a menu with photos and prices, so customers do not ask "how much is the biryani?"
- Write quick replies for the ten questions you get most: delivery radius, opening hours, allergens, how to pay.
- Set an away message for closed hours that says when you reopen and how to pre-order.
Option three: automated ordering on the WhatsApp Business API
The WhatsApp Business Platform (usually called the API) is what you need once a system, rather than a person, should answer. It is the version built for software: it lets an ordering assistant read each message, work out what the customer wants, confirm it, take payment and send the order to the kitchen - without anyone holding a phone. In practice that means a customer writes "2 chicken biryani, 1 garlic naan, deliver to Flat 4, 22 Park Road, around 8", and the assistant replies with the order laid out, the price, the delivery time, and a payment link. When payment clears, the kitchen gets a ticket. If the customer asks whether the korma contains nuts, the assistant answers from the allergen list you gave it, and if it is not sure, it says so and passes the conversation to a member of staff. The API is not free. Meta charges for certain messages you send to customers, and the software that sits on top of it has a subscription. The pricing changes often enough that any number printed here would be wrong within months, so check Meta's current rate card and the provider's own page. What matters is the comparison: an automated assistant typically costs less than one shift a week of a person doing the same job, and it does not go home at 11pm.
What a good ordering assistant must do
Not every "WhatsApp bot" is the same. The ones that lose orders are the ones that make the customer pick from a menu of numbered options and start again when they type something unexpected. Before you pay for anything, check it does all of the following.
- Reads a plain-language order. "Two biryanis and a naan for collection at half seven" should not need the customer to press 1, then 3, then 2.
- Reads the order back and asks for a yes before it confirms. This single step removes most wrong orders.
- Handles changes mid-order - "actually make one of those lamb" - without starting over.
- Captures collection or delivery, the address, and the time, every time, in a fixed structure your kitchen can read.
- Takes payment in the chat and only confirms the order when the payment has gone through.
- Answers menu and allergen questions from information you provided, and refuses to guess.
- Hands over to a person, with the whole conversation attached, when it is unsure.
InfrAgent AI does all of the above on WhatsApp, Instagram, Facebook and your website, from one menu you upload once. If you want to see it take an order for your own menu, book a demo and bring the menu.
The mistakes that cost orders
Whichever option you pick, these are the failures we see most often.
- Not confirming the order back. The customer said "no onions" and nobody saw it.
- No delivery radius stated up front, so the first reply to a customer three miles away is "sorry, we don't deliver there".
- Taking the order but not the payment, then chasing it when the driver arrives.
- Replying with a PDF menu. People on a phone will not read a PDF. Use a catalogue or a plain list.
- Leaving the away message off, so customers who message at midnight think they have been ignored.
The rules you have to follow
Messaging customers on WhatsApp is regulated. The short version: a customer who messages you first can be replied to freely for 24 hours; after that, and for any promotional message, you need their permission and you have to honour "STOP". In the UK that sits under PECR and UK GDPR; in India under the DPDP Act and Meta's own rules. The full detail is in our guide to the rules for messaging customers on WhatsApp.
