To estimate the number of credits your org will use and calculate ROI based on that estimate, access the Agentforce ROI Estimator
To monitor your usage in these usage types, access your org’s Digital Wallet.
Flex Credits usage types as described in this article are based on standard measurement methods. However, some features can have specific limits or exceptions. Refer to your feature documentation for billing details unique to those features.
Actions Usage Types
Actions are the functions the AI agent uses to get information or perform tasks. There are two types of actions: standard and custom.
- Standard agent actions are actions that are available out of the box. See Standard Action Reference.
- Custom actions are actions that are created by you from scratch or by modifying a standard action. To learn more about what customer created actions are, see Create a Custom Action.
Agent actions are billed when they're run, whether they're run deterministically (for example, in reasoning instructions) or during agent reasoning with an LLM. Utilities (escalations to a representative, setting variables, or transitions to another topic) aren't billed as agent actions.
| Billing Category | Description |
|---|---|
| Standard Action | Usage is determined by the number of standard actions called by the agent in a text conversation. Currently, every standard action called by the agent is metered as one standard action, irrespective of the number of tokens processed. Standard agent actions are actions that are available out-of-the-box. To check the list of Standard actions, see Standard Action Reference.  Note Use of some standard agent actions require that a subscription has been purchased for
each user that accesses these actions, such as a subscription to Agentforce for Sales
Add-on or Agentforce for Service Add-on. To determine which subscription is required for
such standard actions, see Standard Action Reference at Standard Action Reference. While this
requirement is not technically enforced yet, users who don’t have the required add-on
license will lose access to such actions for which they don’t have a license when the
requirement is enforced. |
| Custom Action | Usage is determined by the number of custom actions called by the agent in a text conversation. Currently, every custom action called by the agent is metered as one custom action, irrespective of the number of tokens processed. |
| Standard Voice Action | Usage is determined by the number of standard actions executed by the agent in a voice conversation. Note Use of some standard agent actions require that a subscription has been purchased for
each user that accesses these actions, such as a subscription to Agentforce for Sales
Add-on or Agentforce for Service Add-on. To determine which subscription is required for
such standard actions, see Standard Action Reference at Standard Action Reference. While this
requirement is not technically enforced yet, users who don’t have the required add-on
license will lose access to such actions for which they don’t have a license when the
requirement is enforced. |
| Custom Voice Action | Usage is determined by the number of custom actions called by the agent in a voice conversation. Custom actions are actions that are created by you or which result from your modification of a standard action. To learn more about what customer created actions are, see Create a Custom Agent Action. To learn more about how standard actions become custom actions, see Editing Standard Agent Action Reference Actions. |
Agentforce Voice Minutes Usage Type
The Agentforce Voice Minutes usage type is designed for Agentforce Voice Customers as an alternative to Voice Actions usage types. This Usage Type only applies to a limited subset of eligible customers who have purchased a subscription to Agentforce Voice Minutes. Contact your Account Executive for more details on Agentforce Voice Minutes.
| Billing Category | Description |
|---|---|
| Agentforce Voice Minutes | Usage is determined by the duration of the voice call between an end user and Agentforce Voice. Usage is rounded up to the next full minute, meaning any fraction of a minute is treated as a full minute. For example,
If your org has both Agentforce Voice Actions and Agentforce Voice Minutes enabled, Voice Minutes take precedence for billing. When Agentforce Voice Minutes are available in your org, only Agentforce Voice Minutes are metered, and Voice Actions usage types are not applied to the same activity. |
Prompt Usage Types
Prompt usage types are calculated based on the number of calls to the large language model (LLM) gateway and vary depending on the large language model used. Prompt usage types apply to embedded generative AI features such as Service Replies that involve direct requests to the LLM for specific tasks.
| Billing Category | Description |
|---|---|
| Starter Prompts | Usage is calculated based on two factors: the number of direct requests to the LLM via the LLM gateway, and whether the gateway uses a Bring Your Own Large Language Model (BYOLLM). Each starter prompt includes the processing of up to 2,000 tokens. Prompt usage is counted in chunks of 2,000 tokens, rounded up. Prompts that exceed this limit will be metered as multiple prompts, with each additional 2,000-token chunk counting as a new prompt. For example, a prompt with a total of 6,500 input and output tokens will be metered as 4 prompts. Tokens are units of data processed by the AI models. |
Standard Prompts Basic Prompts Advanced Prompts |
Usage is calculated based on two factors: the number of direct requests to the LLM via the LLM gateway, and whether the gateway uses a Salesforce managed large language model. The specific category depends on the model that is used. See Large Language Model Support to find out which usage types apply. All Standard, Basic, and Advanced prompts process up to 2,000 tokens per prompt. Token usage is rounded up in 2,000-token increments. All Standard, Basic, and Advanced prompts that exceed this limit will be metered as multiple prompts, with each additional 2,000-token chunk counting as a new prompt. For example, a prompt with a total of 6,500 input and output tokens will be metered as 4 prompts. Tokens are units of data processed by the AI models. |
Speech Foundation Usage Types
Speech Foundations are AI platform Speech-to-text, Text-to-speech and Translation services. These services empower admins and developers to integrate speech capabilities into workflows such as transcribing voicemails or generating audible alerts. Speech Foundation usage types are metered independently of any other usage types to ensure there are no overlaps in billing. Refer to your feature documentation to determine the applicable usage types for your feature.
| Billing Category | Description |
|---|---|
| Speech-to-Text | Speech-to-Text converts spoken audio into written text, a process run by automatic speech recognition (ASR) models. Usage is calculated based on the duration of the audio processed for each transcription, in seconds. In Digital Wallet, this usage is aggregated and displayed in minutes. |
| Text-to-Speech | Text-to-Speech converts written text into natural-sounding spoken audio, a process run by automatic Speech Synthesis models. Usage is metered by the number of text characters processed for the speech generation. In the Digital Wallet, this usage is aggregated and displayed in units of million characters. To understand how your consumption appears in the Digital Wallet, consider a scenario where you process 9,000 characters for conversion from text to speech. Because this usage is in units of one million characters, your actual consumption is 0.009 units (9,000 divided by 1,000,000). In the Digital wallet, this usage is rounded to two decimal places and the value is displayed as 0.01 units. |
| Translation | Translation converts text from one human language into text of another, a process executed by machine translation models. Translation usage is metered by the number of characters processed for the translation. To understand how your consumption appears in the Digital Wallet, consider a scenario where you process 9,000 characters for translation. Because this usage is in units of one million characters, your actual consumption is 0.009 units (9,000 divided by 1,000,000). In the Digital wallet, this usage is rounded to two decimal places and the value is displayed as 0.01 units. |
