The API vs the app
The WhatsApp Business App is fine for a solo founder. But once you have a team, volumes of enquiries, or need automations, the WhatsApp Business API is the upgrade. It lives on your own infrastructure (I host it for clients on a subdomain), supports multiple agents, and lets you send approved template messages and run broadcasts.
Verification and approvals
You will need a Meta Business account, a business phone number, and to pass Meta’s business verification. Template messages-the only kind you can send proactively-go through Meta approval. Clean, honest templates get approved fast; anything spammy gets rejected. I handle all of this as part of the WhatsApp CRM setup.
What changes in daily operations
A shared inbox where every thread is assigned and annotated. Pipelines that show deal stages. Automations that welcome new contacts, chase unanswered replies and route leads by keyword. And an AI assistant that drafts replies from your own knowledge base-handing off to a human when it cannot help.
Costs and expectations
Meta charges per conversation for API usage. Setup includes the CRM, hosting and integration; there is also the VPS to run it. Budget-wise, this pays for itself the moment a single high-value deal that would otherwise be lost converts.
