Short answer. Use the free WhatsApp Business app if one phone and a small team answer chats by hand. Move to the WhatsApp Business Platform (the API) when you need chatbots, several agents on one number, CRM integration or approved template messages sent at scale.
What the WhatsApp Business app is
The WhatsApp Business app is a free app for small businesses. It adds a business profile, a product catalogue, labels, quick replies and greeting or away messages to ordinary WhatsApp. Everything is handled manually from a phone, with the desktop and web versions available as companions.
It works well for a shop, clinic or service business where a few people reply personally. Its broadcast lists only reach people who have saved your number, and it cannot be connected to other software.
What the WhatsApp Business Platform is
The WhatsApp Business Platform, often called the API, is offered by Meta directly and through approved Business Solution Providers. It has no chat screen of its own. You connect it to software such as a CRM, a shared inbox or a chatbot, and that software sends and receives the messages.
Key differences
- Automation: the app offers simple auto-replies. The Platform supports chatbots, lead qualification, appointment flows and automated follow-up.
- Team access: the Platform lets many agents work from one number through a shared inbox.
- Integration: the Platform can log every conversation in your CRM. The app cannot.
- Messaging first: on the Platform, once the 24-hour customer service window has closed, you can only message a customer with a pre-approved template.
- Cost: the app is free. The Platform involves Meta message charges and, usually, a provider fee. Rates change, so check Meta's current pricing before you budget.
Consent still applies
Whichever you use, message people who have agreed to hear from you. On the Platform you need a recorded opt-in before sending template messages, and you should keep that record.
When it is time to switch
- Enquiries wait because only one person can answer the phone.
- You want a bot to handle common questions or collect lead details first.
- You need every conversation recorded against a customer in a CRM.
- You want to send appointment reminders or follow-ups to opted-in customers at scale.
