Sendbot uses a credit system to bill for platform usage. Each action has a different cost based on the resources consumed.

How Credits Work

The credit system is straightforward:
  • Recurring Credits: Renew monthly with your plan
  • Purchased Credits: One-time purchases that never expire
  • Usage Priority: Recurring credits are consumed first, then purchased credits

Usage Table

Chat Sessions

*The configured official-channel rate is 2 credits. Provider fees, when applicable, are billed by the provider/account owner.
A session is counted when the user starts a conversation with the bot, not per message.

AI and Content Generation

*AI Agent usage depends on the model and number of tokens used.

AI Agent Cost Calculation

When you use Sendbot’s API key instead of your own:
If you use your own API key, AI Agent does not consume Sendbot credits, only usage from your provider account.

Checking Your Balance

In the Dashboard

You can see your current credit balance in the top-right corner of Studio.

Low Balance Alerts

For prepaid workspaces, the system sends a low-balance email when the available credit balance reaches 20% or less of the workspace’s recurring credit allowance. The warning is throttled so the same workspace is not emailed more than once within 24 hours.
  • Above 20% of the allowance - No low-balance email
  • 20% or below - Low-balance warning
  • 0 credits - New prepaid usage is blocked until credits are available
Purchased credits are included in the available balance. They are not divided by 100 or displayed as currency: 996 credits means 996 credits.

Billing Models

For entry-level plans
  • Service stops when credits run out
  • Auto-recharge is available
  • Best for tighter spend control

Auto-Recharge

Configure auto-recharge so you never run out of credits:
  1. Open Workspace -> Subscription
  2. Enable Auto-Recharge
  3. Configure:
    • Trigger: a monetary threshold in the workspace billing currency
    • Amount: the monetary amount to charge when auto-recharge runs
The Studio shows both values in the workspace billing currency. Internally they are stored in the currency’s minor unit (for example, 1000 = R$ 10.00 when the billing currency is BRL). The trigger is converted to its current credit equivalent using the active pricing configuration before the balance comparison.
