WhatsApp Business app or WhatsApp Business Platform? What Meta says each one is for

Meta offers businesses two ways to use WhatsApp: a free app on a phone, and a platform that a system connects to. Most businesses start on the app, and the question is when, if ever, to move. Meta's own pages describe who each one is for, what each costs and how a business gets onto the Platform.

What Meta says each one is for

WhatsApp Business app
For small businesses talking to customers from a single device. Meta's FAQ says it is free to download and free to use, lets a business reach hundreds of customers, and offers limited customisation and integration with other tools.
WhatsApp Business Platform
For medium and large businesses talking to customers at scale. A system, rather than a person holding a phone, sends and receives the messages, so the number can be joined to the rest of the business's software. Meta's FAQ says it lets a business reach millions of customers at a time.

Side by side

Who answers
On the app, whoever holds the phone. On the Platform, the number can feed an inbox several staff share, customer-support software or a chatbot, and Meta's Platform page describes passing a chat to a person only when one is needed. Meta's Business Help Center adds that a business on the Platform can connect thousands of agents and bots to its customers, and join the number to back-office systems such as customer-records and marketing software.
What the app gives you
Meta's app page lists a business profile, a showcase of products with prices that can be shared in a few taps, a greeting when someone first writes and an away message for when nobody is free.
What the Platform adds
Meta's features page lists reply buttons and list messages, payments inside the chat, read receipts for each contact, single- and multi-product messages, and entry points such as a button on the website or a QR code on packaging.
Ads that open a chat
Meta's Business Help Center says ads with a button that opens WhatsApp work with either one. On the app, you connect the WhatsApp account to the business's Facebook Page and make yourself an admin of that Page. On the Platform, the business requests to connect its Facebook Page to the Platform number, and that connection is then approved.
Writing first on the Platform
Customers can always write first. Once a customer has agreed to hear from the business, it can write first too, but only with a message built from a template, which may be text, media or interactive.
What it costs
The app: nothing to Meta, its FAQ says, with Meta One as an optional paid subscription inside it. The Platform: no fee from Meta for direct access, but Meta charges for each message it delivers, at rates that depend on the kind of message and the country. Since 1 October 2026 that includes service messages after the first 1,000 a month on each number.

Two ways onto the Platform

Meta's FAQ describes two routes. A business can sign up directly, but Meta says it must be a developer to do so, because the work is calling Meta's programming interface and setting up webhooks, the address where Meta delivers incoming messages to the business's system. Or it can work with one of the providers Meta approves, which Meta suggests for businesses without developers and for those that want WhatsApp joined to an inbox, support software or a chatbot.

The route changes who deals with Meta. A business that connects directly pays Meta itself, by card or a credit line, and asks for help through Meta's Direct Support portal. Through a provider, Meta bills the provider for the messages, the provider can raise support tickets on the business's behalf, and the provider may add its own fees for what it supplies. Meta Business Agent, Meta's AI agent, is the exception: Meta charges the business for it directly either way. What the setup involves step by step is in the Cloud API guide.

How to tell which one you need

  1. Stay on the app while one phone is enough. One person answers, customers number in the hundreds, and nothing else needs to know what was said in the chat.
  2. Look at the Platform when the phone is the bottleneck. Several staff need the same number, order updates should go out without anyone typing them, or a list of customers who agreed to hear from you has grown past what one person can message.
  3. Count the cost before moving. The app costs nothing in Meta fees. On the Platform, Meta charges per message, explained in the pricing guide.
  4. Delete nothing first. A number already on the app cannot simply be registered on the Platform, as the phone number guide explains. Whether to keep the app alongside a system is a separate decision worth talking through first.

Questions

Can we run ads that open WhatsApp on either one?

Yes. Meta's Business Help Center says ads that click to WhatsApp can be used by businesses on the app or on the Platform. The difference is how the number meets the Facebook Page: the app connects to the Page directly, with you as its admin, while a Platform number needs a request to connect the Page, which is then approved.

Is the WhatsApp Business app really free?

Meta's FAQ says it is free to download and free to use. Meta One, an optional subscription inside the app, is the paid extra.

How do we start on the WhatsApp Business app?

Meta's getting-started page lists the steps: download the app from Google Play or the App Store, agree to WhatsApp's Terms of Service, enter the business number and confirm it, then type in the code WhatsApp sends by text or call. You can let the app use your contacts and photos, and restore an earlier Business app account from a Google Drive backup. Last comes the profile: business name, category and a logo or profile picture. Meta's page adds that an account on the regular WhatsApp app can be moved to the Business app.

Does Meta charge a monthly fee for the Platform?

Not for direct access, Meta's FAQ says. Meta charges for the messages it delivers. A provider may charge its own fees for the service and software it adds.

Meta's FAQ also says businesses pay per conversation. Which is right?

The FAQ still carries an older line about paying per conversation. Its pricing answer on the same page, and Meta's pricing page, say Meta has charged per message since 1 July 2025, by message category and country.

Do we need a developer to use the Platform?

To connect directly, yes: Meta says signing up yourself means calling its programming interface and setting up webhooks. Without a developer, a business works through a provider that has done that work.

Outgrown the app?

We set up a business's WhatsApp on a proper system, so several staff can answer one number and order updates go out on their own. A short call is the easiest way to see whether your business has outgrown the app yet.
