Twilio vs WhatsApp Business API — which one does your business need?
Quick guide to picking the right SMS/WhatsApp infrastructure (and why you don't have to pick alone).
Published 26 March 2026 · by the ChatBooker team
What each is
- Twilio: SMS provider. Send and receive texts globally. ~$0.05 per SMS in Australia.
- WhatsApp Business API: Send/receive WhatsApp messages from a business number. ~$0.04 per conversation.
Why setting it up is hard
Both require:
- Approved business number (1-2 weeks).
- Identity verification.
- Message template approval (for proactive sends).
- Webhook infrastructure to receive messages.
Most agencies charge $3-5k for this setup.
