RCS for Business messaging traffic is billable under either the
[Standard](https://developers.google.com/business-communications/rcs-business-messaging/carriers/billing/rbm-billing-faq)
or the [US model](https://developers.google.com/business-communications/rcs-business-messaging/carriers/billing/us-billing-model),
depending on the message destination. Under both models, rates are determined by
the agent's pre-selected billing category: conversational or
non-conversational--and are billable according to the carrier's rate card. Each
carrier's rate card determines whether a billable event results in a charge or
not.
