From Oct 1, 2026
Every outbound message is charged
The 24h window still exists, but each company message costs R$ 0.035. In this chat: 4 messages × R$ 0.035 = R$ 0.14.
Seems small? Multiply it.
An operation with 3,000 chats/month like this one starts paying R$ 420.00/month (R$ 5,040.00 per year) on service alone.
Tighter flows — bot + human — cut messages per chat and the bill impact.

Every format counts as a message
Under the new model, content does not matter: each delivered message generates a R$ 0.0350 charge, whether it is a short text or a video.

FAQ
Are inbound customer messages charged?
No. Billing covers delivered messages sent by the business.
Does the 24-hour window disappear in October?
No. It still opens customer care, but outbound replies gain a unit cost.
Do text, audio and image have different prices?
Under per-message pricing, format does not change the category: each delivery counts as one message.
Does this calculator replace Meta’s invoice?
No. It helps operational planning. Always validate the live table in official docs.
