WhatsApp Business, explained

What WhatsApp Business is, how it works and when it gets too small

WhatsApp Business is Meta's free app for businesses to talk to customers. It works like regular WhatsApp, but with a business number and extra tools: a profile with address and hours, a product catalog, automatic welcome and away messages, labels to organize conversations and quick replies.

WhatsApp Business Web: how to open it on a computer

You don't need to install anything. WhatsApp Business Web is the same address as regular WhatsApp, web.whatsapp.com. There is no separate website for businesses.

You open the address in your computer's browser. On your phone, you open WhatsApp Business, go to the option to link a device and point the camera at the code on the screen. The business's conversations then appear on the computer. There is also a WhatsApp desktop app, which is optional.

Two things to know. Meta's AI can only be set up, paused or deleted in the phone app, never in the browser. And the connected computer is still the same number, with the same conversations as the phone: it helps you type faster, it does not create a second customer service line. How many devices you can connect, how to use it on two phones and what doesn't work on the computer are in WhatsApp Business Web: on a computer and on several devices.

What are the versions of WhatsApp for business?

There are three ways for a business to use WhatsApp, plus regular WhatsApp, where almost everyone starts. "WhatsApp for business", "corporate WhatsApp" and "professional WhatsApp" are not separate products: they are names people give to one of these.

01

Regular WhatsApp: the personal one

It is the app for chatting with family and friends. It has no business profile, catalog or automatic message. You can sell through it, but nothing there helps you organize customers.

02

WhatsApp Business: the free app

Made for small businesses. It has a business profile, catalog, greeting and away messages, labels and quick replies. It is free, runs on your phone and can also be opened on a computer.

03

Paid plans inside the app

They are Meta subscriptions nobody is required to buy: Meta Verified and Meta One, which arrived in Brazil in September 2026. They bring a verification badge, more connected devices and more replies from Meta's AI. It is what many people search for as WhatsApp Business Premium.

04

WhatsApp Business Platform: the official API

It is not an app. It is the connection Meta offers so a system can send and receive messages on the business number, for businesses with several people answering or an AI replying. Meta charges per message, and the partner that connects the number charges for the software.

WhatsApp conversation with a demo gas and water distributor: the customer asks for a gas cylinder swap and two water jugs and the AI notes the order with prices and asks for the address and payment method
CertuAI demo with a fictional distributor, on the Platform: the AI reads the order, adds up the prices from the table and asks for what is missing. The free app's automatic message is always the same text and does not do this.

How to start on WhatsApp Business for free, step by step

The steps follow what Meta shows people who are just starting. Almost everything is in the Tools tab of the app, and the names can change a little between Android and iPhone.

  1. Download the app and confirm the number

    Download WhatsApp Business from your phone's app store and enter the business number. Meta sends a code by text message or by phone call. If the number was already on regular WhatsApp, you can bring over the account data.

  2. Fill in the business profile

    Name, category and logo are the minimum. Then add a short description, business hours and the website. It is what the customer sees when they tap the business name.

  3. Set up the catalog

    Add your products or services with a photo, name and price. Customers can browse without having to ask, and you send the catalog link in the conversation, on Instagram or on Facebook.

  4. Turn on the greeting message

    It goes out automatically to anyone who writes to the business for the first time. Say the business name and what the person can ask for there, in two or three lines.

  5. Turn on the away message

    It replies on its own outside the hours you choose and says when you are back. It only lets people know: it always sends the same text, whatever the question.

  6. Create labels

    Create labels like New customer, Awaiting payment and Paid. With them you filter conversations and quickly find who still needs a reply.

  7. Save quick replies

    Turn what you type every day into shortcuts: prices, address, payment methods. In the conversation, you send the ready-made reply in a few taps.

It is the same list as the steps, seen from the side of the limit. The right-hand column is where the owner starts to miss something.

Does WhatsApp Business cost money?

No. The WhatsApp Business app is free to download and to use: messages, profile, catalog, labels and automatic messages cost nothing. Meta itself repeats this on the Meta One page: the subscriptions are optional and the free app stays free. Three things around it are paid, and that is where the confusion comes from.

The business broadcast, sending to many people that reaches even those who haven't saved your number, costs R$ 0.3217 (Brazilian reais) per message delivered in Brazil, before taxes. The regular broadcast list is still free.

Meta's paid plans inside the app, Meta Verified and Meta One, are optional.

The WhatsApp Business Platform, the official API, is a different product, and on it Meta charges per message. Starting October 1, 2026, it also charges for the replies a business sends in the 24 hours after the customer's message: R$ 0.035 each in Brazil, after the 1,000 free ones each month on each number. People who use only the app are outside this charge. What changes is in WhatsApp will charge per message in October 2026.

And people who write to a business never pay anything, in any of these cases.

Does WhatsApp Business Premium still exist?

Under that name, it doesn't appear on the Meta pages we checked on September 25, 2026. What exists today inside the app is two paid plans.

Meta Verified gives a verification badge, protection against people impersonating your business, priority support, a web page with an easy-to-remember address and up to ten devices and agents on the same account, per the app features page. Meta One, which arrived in Brazil on September 15, 2026, brings the best of Meta Verified and adds more replies from Meta's AI. Each subscription covers one number.

In Meta's announcement, the Meta One plans for businesses start at R$ 59 (Essential), R$ 199 (Advanced), R$ 599 (Expert) and R$ 1,999 (Maximum) per month. Meta says the plan, price and benefits change by region and by account, and that what applies to you appears when you start subscribing.

Is it worth subscribing? For the badge or more devices on the same number, the plan does the job. A customer record and an automatic message for people who went quiet don't appear in any app plan we read.

Do you need a SIM card to use WhatsApp Business?

You need a number that can receive the confirmation code. At sign-up, Meta sends a code by text message or by phone call, and you type it into the app, as shown in Meta's step-by-step. After that, messages go over your phone's internet or wifi.

A landline works. Since the code can also arrive by phone call, you can register the store's or practice's landline: on the phone where the app is installed, enter the landline number and request the code by call. The customer talks to the number they already know from the storefront.

A virtual number may work, with one caution. It has to receive the text message or the call with the code, so ask the seller before you pay. And choose a number that stays in your name: it is where the code arrives if you ever need to confirm the account again.

Two WhatsApp Business accounts on the same phone. The simplest way is regular WhatsApp on one number and WhatsApp Business on the other: they are two separate apps. For two business numbers on the same device, open Settings in WhatsApp Business and see whether your app shows the option to add another account. If it doesn't, use a second device.

Is the WhatsApp Business broadcast list paid now?

Only one of them. The app has two ways to send the same message to many people. The regular broadcast list has no charge, but only reaches people who saved your number in their contacts. The business broadcast also reaches people who didn't save it, shows how many read and how many replied, and is paid: R$ 0.3217 (Brazilian reais) per message delivered to a Brazilian number, before taxes. Sending to 1,000 customers comes to R$ 321.70.

Charging began in Brazil in October 2025, and today's amount is from Meta's price table in reais that has been in effect since July 1, 2026. You only pay for the delivered message, and the app shows the total cost before sending. On the Platform, sending to many people is by approved template and costs the same per advertising message. The math and the spending limit are in are WhatsApp Business broadcast lists paid now?

Meta's AI is answering my customers. How do I turn it off?

Delete the AI agent from the phone app. That AI is the Meta Business Agent, which Meta is rolling out in WhatsApp Business to selected businesses. It appears in the Tools tab under one of these names: AI agent, Your AI agent or Meta Business Agent.

On Android: Tools › Meta Business Agent › Reply settings › Disconnect AI › Disconnect and delete AI. On iPhone the path is the same, but the button is called Delete your AI agent. It can't be done through WhatsApp Web. The steps are from the WhatsApp Help Center.

Pausing is not turning off. While paused, the AI stops answering new conversations, but it keeps learning from them. While it is on, Meta receives the conversations to improve its own AI, and the Help Center warns that the greeting, the away message and broadcast lists may stop working. The AI assistant that appears in the search bar is a different one: it doesn't answer customers and has no official off button. The step-by-step for Meta's three AIs is in how to turn off WhatsApp Business AI.

To be fair to it: Meta's AI also learns from what your business shows it, such as the catalog, website and old conversations. The difference is in what comes around it. On the Help Center pages about the app, read on September 24, 2026, it asks for the customer's details, but it doesn't appear to create a record or a task, or to reach back out to people who went quiet. The AI agent platforms that do this, with prices and sources, are in the top 5 AI agents for WhatsApp.

When does the free app get too small?

The app is enough as long as one person can read and answer everything quickly. If you answer in minutes and have never lost a sale to delay, stay with it: switching would only cost you money. These are the signs that your volume has outgrown it.

More than one person answering. When two or three people share the same number, you get the message that was read and nobody answered, and the customer who gets two different replies.

A customer waiting outside business hours. The away message says you aren't there, but the question stays unanswered until you are back. Whoever wanted to know the price at that moment still doesn't know.

A fixed message that doesn't understand a question. The greeting and the away message always send the same text. The customer asks if there is an opening tomorrow and gets the same welcome as always.

What was agreed lives in someone's head. The label helps, but what was promised to each customer sits in the phone's history. If whoever handled it goes on vacation, the matter stalls.

What if you want an AI answering with what your business knows?

That is what CertuAI does. CertuAI builds an AI team that answers on your number 24 hours a day, using the business Brain: the place where your services, prices, hours and rules live, along with what you would rather nobody answer. When a question goes beyond what it learned, it hands the conversation to you.

Each conversation becomes a contact in the organized list of your customers, your team handles them together on the same dashboard, and people who stopped replying get a new message without you doing anything. The number stays yours, and CertuAI is a Tech Provider of Meta's WhatsApp Business Platform.

Plans start from US$ 75 per month. See how it works in customer service automation on WhatsApp or compare the CertuAI plans.
