01The four dates that matter
The bill switches to reais
Brazilian customers start being invoiced in BRL, by Facebook Brasil (gradual rollout). The APIs to migrate your currency have been live since June 1, 2026.
The AI starts the meter
The Meta Business Agent starts charging per token: US$ 2.00 per 1 million tokens, a single global rate — including inside the window and at the free entry point.
Support lands on the invoice
Service messages start being charged per send, at the market's utility rate. Service gets no volume discount.
Reais deadline
The cutoff to migrate every WABA to BRL. On July 1, 2027, accounts still outside reais stop delivering messages.
02Your math in 30 seconds
Messages × Tickets × Rate
Multiply the service messages per ticket by your monthly tickets and by the reference rate. That is the number that leaves zero on October 1.
03Reference rates (Brazil)
- Serviço R$ 0,0350
- Utility R$ 0,0350
- Autenticação R$ 0,0350
- Marketing R$ 0,3217
04The move that zeroes out support
Hybrid strategy
Notifications and campaigns go through the official channel; 1:1 support is concentrated on an alternative channel (at your own risk); and AI runs on your own key, in place of the Meta Business Agent. One inbox, three engines.
-
Official where the seal matters (notifications, campaigns, OTP)
-
1:1 support kept in one place — fewer billed sends
-
AI on your own key — you control the model cost

Measure where you are today
How many service messages go out per conversation and per month? Without that number, you can't reprice.
- 02
Sort by type
Decide what needs the official channel (notifications, campaigns) and what can go through an alternative channel (1:1 support, at your own risk).
- 03
Trim the conversation
Swap the back-and-forth for lists and buttons: fewer sends, lower fees.
- 04
Reprice your service
Factor the new per-message cost into your math and adjust price and margin before it hits your cash flow.
- 05
Migrate to reais
Switch your currency within the deadline (Jun 30, 2027) so you don't stop delivering.
