What does the WhatsApp Business API cost?
Meta charges per delivered conversation. Easy Flow Builder adds a fixed platform fee of €50 per month — with no per-seat pricing.

WhatsApp Business API costs are mainly Meta’s conversation fees by category (marketing, utility, authentication, service), plus optionally a platform like Easy Flow Builder (€50/month all-in). Service messages within 24 hours of a customer message are typically free from Meta.
How Meta bills
Meta bills per delivered conversation, not per individual message. Categories: marketing, utility, authentication, and service. Rates vary by country and change; always check Meta’s current rate card.
The 24-hour service window: once a customer messages you, you can typically send free service replies for 24 hours (Meta). After that you need an approved template for outbound.
Platform vs Meta
Many providers hide pricing behind a demo. Easy Flow Builder is €50 per month or €550 per year: unlimited flows and platform messages, no seats.
You therefore pay: (1) Easy Flow Builder, (2) Meta conversation fees via your WhatsApp Business account.
Cost components (indicative)
| Component | Who | Indication |
|---|---|---|

| Utility / authentication | Meta | Per country — lower |
| Service in 24-hour window | Meta | Typically €0 |
Worked examples
Appointment reminders (utility)
Say 500 reminders per month: platform €50 + Meta utility × 500. Exact Meta rates: check the Meta rate card for your country.
Support inside the window
Replies within 24 hours of an inbound message: Meta service often €0; you mainly pay for the platform.
Marketing campaign
Outbound templates outside the window are marketing — usually Meta’s most expensive rate. Budget this separately from your €50 plan.
