Use the free WhatsApp Business app if one or two people answer a manageable number of chats by hand. Use the WhatsApp Business Platform, often called the API, if you need automation, several staff in one inbox or a link to your booking or order system. This guide explains the difference in plain words and helps you choose.
The two products in one minute
Meta offers two different ways for a business to use WhatsApp. They share a name, but they work very differently.
- WhatsApp Business app. A free app for your phone. You install it, register a number and chat with customers by hand. It adds a business profile, opening hours, a small catalogue, labels, quick replies and simple automatic greeting and away messages.
- WhatsApp Business Platform. This is the API. It has no app of its own. Software connects to WhatsApp for you: a shared inbox tool, a bot, a booking system or a custom build. It is made for automation and for teams, and it comes with stricter rules and message fees.
Neither one is the better product. They are built for different stages of a business.
Side by side comparison
| Point | Business app | Business Platform (API) |
|---|---|---|
| Cost to use | Free | Meta charges for messages, plus the cost of your software or provider |
| Setup | Minutes, on your phone | Meta business account, number registration and a software tool |
| Who answers | A person, by hand | A person, a bot, or both |
| Team use | One phone plus a few linked devices | Many staff through a shared inbox tool |
| Automation | Greeting, away message, quick replies | Full flows: questions, bookings, orders, handover |
| Links to other systems | Very limited | Calendar, shop, CRM and more |
| Starting a chat with a customer | Typed by hand, with their permission | Only with opt-in and an approved message template |
Features change over time on both sides, so check Meta's current pages before you decide.
The rules that come with the Platform
The Platform gives you more power, and Meta attaches clear rules to it. Four of them matter for a small business.
- Opt-in. You need the customer's permission before you message them. See the guide on WhatsApp opt-in.
- The 24-hour customer service window. When a customer writes to you, a window of 24 hours opens. Inside it you can reply in free form.
- Message templates. Outside that window you can only send templates that Meta has approved in advance, for example an appointment reminder.
- Fees. Meta charges for messages on the Platform. The pricing model has changed over time and differs by country and message type. Do not rely on old blog posts. Look at Meta's current pricing page before you plan a budget.
Your local privacy and marketing laws apply to both products, and they differ by country. This is general information, not legal advice.
When the free app is enough
Stay with the Business app if most of these are true:
- One or two people answer all chats.
- You can answer during the day without stress.
- Customers ask simple things and you do not need to look up data in other systems.
- You rarely need to send reminders or updates to many customers.
You can get a lot out of the app with three small steps: fill in the business profile fully, save quick replies for your five most common questions, and set an honest away message.
Thanks for your message. We are closed right now and will reply on [day] from [time]. For urgent matters please call [number].
Signs that you need the Platform
- Messages arrive at night and at weekends, and people expect an answer.
- Several staff need to see and answer the same chats without sharing one phone.
- The same questions take up a large part of your day.
- You want customers to book, move or cancel appointments in the chat.
- You want order confirmations or reminders to go out automatically.
- You want to know who answered what, with a clean history per customer.
One sign alone is usually not enough. Two or three together mean the manual way is costing you time or enquiries.
How to move from the app to the Platform
- Decide on the number. In the classic setup a number runs on either the app or the Platform. Meta has introduced ways to use both together in some setups. Ask your provider what is possible today, and what happens to your chat history.
- Create or tidy your Meta business account. Use your real business name and details. Meta may ask you to verify the business.
- Choose the software. This can be a shared inbox, a bot or a tool you already use that supports WhatsApp.
- Write your first templates. Start with two or three, such as a booking confirmation and a reminder. The guide on templates and the 24-hour rule shows how.
- Collect opt-ins from day one and keep a record.
- Test with your own phone before customers see anything.
If you want this built for you, the WhatsApp Bot from Astranode runs on the official WhatsApp Business Platform and is in early access.
Start with the free app while chats are manageable by hand. Move to the Platform when you need automation, a team inbox or system links, and plan for opt-in, templates and message fees.
