01The four dates that matter

01 Jul 1, 2026

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.

02 Aug 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.

03 Oct 1, 2026

Support lands on the invoice

Service messages start being charged per send, at the market's utility rate. Service gets no volume discount.

04 Jun 30, 2027

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

Messages per conversation × Conversations per month × R$ 0,0350 = Cost per month

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)

Message type Per message
  • 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

only what's needed

05Six moves before October

  1. 01

    Measure where you are today

    How many service messages go out per conversation and per month? Without that number, you can't reprice.

  2. 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).

  3. 03

    Trim the conversation

    Swap the back-and-forth for lists and buttons: fewer sends, lower fees.

  4. 04

    Reprice your service

    Factor the new per-message cost into your math and adjust price and margin before it hits your cash flow.

  5. 05

    Migrate to reais

    Switch your currency within the deadline (Jun 30, 2027) so you don't stop delivering.

  6. 06

    Build the hybrid

    One inbox, three engines: official, an alternative channel and AI on your own key.
