Understanding WhatsApp Business API pricing is essential for budgeting your business communication in Brasil. This guide breaks down conversation-based pricing, free tiers, and how to optimise your spend.
How Conversation-Based Pricing Works
Meta charges per 24-hour conversation window, not per message. Once a conversation starts, you can exchange unlimited messages for 24 hours. Conversations are categorised as Marketing, Utility, Authentication, or Service — each with different rates.
Free Tier: 1,000 Service Conversations
Every WhatsApp Business account gets 1,000 free service conversations per month. Service conversations are initiated by the customer (they message you first). This is enough for many small businesses.
Platform Costs: App-ening Plans
App-ening charges a monthly platform subscription separate from WhatsApp conversation costs. Plans start at $29/month (Starter). You also maintain a prepaid message wallet for WhatsApp API charges.
How to Reduce Costs
Use service conversations (free tier) by encouraging customers to message first — e.g., via Click-to-WhatsApp ads, QR codes, and chat widgets. Combine multiple messages within the 24-hour window. Use template messages efficiently.
Cost Comparison: WhatsApp vs Email vs SMS
WhatsApp: higher per-message cost but 98% open rate. Email: cheaper but 20% open rate. SMS: comparable cost but lower engagement. For most businesses in Brasil, WhatsApp delivers the best ROI per dollar spent.
