WhatsApp Business
Why WhatsApp Business
WhatsApp Business is Meta's way for companies to talk to customers on WhatsApp. It comes in two forms: a business app built for small business owners, and the WhatsApp Business Platform, an API that lets larger companies send notifications and run support and sales conversations. It suits businesses whose customers already live in WhatsApp.
What it does
WhatsApp Business has two parts. The WhatsApp Business app is built for small business owners. It gives you a business profile, a product catalogue, automated greetings and away messages, and tools to manage customer conversations.
The WhatsApp Business Platform is the API side, aimed at companies that want two-way conversations at scale. It supports notifications, promotions and verification messages, commerce, customer support and custom conversational experiences with interactive features and rich media. The Cloud API is built on the Graph API and works over plain HTTP.
Why you would need it
Your customers already use WhatsApp every day. If you only offer email and a contact form, you lose the conversations that would have happened in the app they open first. If you answer from a personal phone, replies live in one person's pocket, with no history, no routing and no way to hand a chat to a colleague.
The business app fixes the basics for a small team. The platform fixes the bigger problem: turning WhatsApp into a proper channel that your helpdesk, CRM or chatbot can read and write.
Where it fits
WhatsApp is a channel, not a system of record. Click-to-WhatsApp ads from Meta Ads and buttons on your site feed it with new conversations. It feeds your helpdesk, CRM and chatbot, so the chat history sits next to the customer record.
Tools such as Help Scout, Botpress and Manychat can use WhatsApp as one of their messaging channels. It sits next to email and live chat rather than replacing them.
What stands out
- A free service window. Non-template messages are free inside an open customer service window, and utility templates sent inside that window cost nothing.
- A 72-hour free entry window when a customer starts the chat from a Click-to-WhatsApp ad or a page button.
- Webhooks that deliver incoming messages and message status updates to your server as JSON.
- Two ways in: the app for a small team, and the API when you outgrow it.
My take
I'd pick WhatsApp Business whenever the customers in your market already prefer WhatsApp. Start with the app to learn what people ask. Move to the platform once volume or compliance means chats must land in a real system.
What I'd watch is that you are building on Meta's platform. Message rules, template approval and pricing categories are set by Meta, not by you, so keep your core customer data in your own CRM.
Verdict
Pick it when your customers want to message you and you can route chats into a helpdesk or CRM. Skip it when your audience does not use WhatsApp, or when you only need occasional broadcast emails.
Notes

Before you choose
Two products, pick the right one
The app is for a person with a phone. The platform is for a company with a system behind it. Many small teams start with the app and hit its limits quickly, so decide early whether you need the API.

Template messages and consent
Messages you start outside an open customer window use approved templates, and marketing templates are always charged. Check Meta's rules on templates and customer consent before you plan outbound campaigns.
Cost follows volume
The platform charges per delivered template message, by category and by the country of the recipient. Lower rates for utility and authentication messages depend on monthly volume, so model your real message mix before you commit.
You depend on Meta
Policies, pricing and approval rules can change. If WhatsApp becomes your main support channel, keep an email or live chat fallback, for example through Intercom, so one policy change does not cut you off from customers.
