Workflow runs are free. You only use credits when a successful run completes an action that has a credit cost. Most workflow steps are free, including triggers, conditions, branches, filters, waits, contact updates, and labels. This means a workflow can run without using any credits if it does not complete a paid action.

​
Flat-cost actions

These actions have a fixed cost each time the step finishes: Each occurrence of a finished step is charged once. If the same action appears twice and both steps finish, both are charged.

​
Send message actions

Message actions are charged for each message sent. An AI-generated message adds 3 credits to the channel’s base cost. Inbound messages do not use credits.

​
Voice Agent Call actions

A Voice Agent Call action uses 6 credits per minute. The charge is based on the call’s duration. Regular voice calls are not a workflow action. Outside workflows, regular voice calls use 1 credit per minute. See How credits work for non-workflow rates.

​
What costs nothing

The following do not use credits:
  • Starting or running a workflow
  • Triggers
  • Conditions, branches, and filters
  • Waits and delays
  • Creating or updating a contact
  • Updating contact fields or inbox assignment
  • Adding labels
  • Any other step not listed as a paid action above
Only steps that finish are included in the calculation. If the entire workflow run fails or is cancelled, the run uses 0 credits, even if some steps finished before it stopped.

​
Example calculation

Suppose a five-step workflow:
  1. Starts when a contact is updated
  2. Checks a condition
  3. Waits for a time window
  4. Updates a contact field
  5. Sends a non-AI SMS
The trigger, condition, wait, and contact update are free. The SMS costs 2 credits, so one successful run uses 2 credits total. If the run fails or is cancelled, it uses 0 credits. To see the credit usage for each workflow and run, go to Settings > Billing. For rates outside workflows, see How credits work.
