 ## Action pricing {#action}
 
-**What is an Action?**
+**What's an Action?**
 
 Actions serve as the primary unit of consumption-based pricing for Temporal Cloud.
 Temporal Actions are the building blocks for Workflow Executions.
 When you execute a Temporal Workflow, its Actions create the ongoing state and progress of your Temporal Application.
 
 Actions are collected and billed monthly for each Namespace.
-The base rate is $25 per one million Actions per month (across all Namespaces).
+The base rate is $25 per one million Actions per month.
+This rate applies across all Namespaces.
 You will be billed for a prorated portion of the Actions you use.
 If you use fewer than one million Actions per month, your bill for Actions will be less than $25 for that month.

-Temporal Cloud also offers a credit system.
+### Credit System {#credit-system}
+
+**How does Temporal Cloud's credit system work?**
+
+Temporal Cloud offers a credit system.
 Credits provide an additional discount schedule for billable Actions and [storage](#storage).
 Credits do not expire.
 
-The credits applied to a Temporal Cloud Account include volume-based discounts for each Namespace.
-Pricing may not be uniform per Namespace.
-For example, under one credit commitment, a Namespace may use up to 300 million Actions priced at $23.25 per million Actions.
-Another Namespace with over 300 million Actions benefits from a reduced rate of $18.80 per million Actions for any Actions beyond the 300 million mark.
+Credits applied to a Temporal Cloud Account unlock volume-based discounts.
+Discounts are applied separately to each Namespace so pricing may not be uniform between Namespaces.
+For example, consider an account eligible for volume discounts using two Namespaces, one with 100 million Actions and one with 500 million Actions:
+
+- The first Namespace using 100 million Actions is billed at the $23.25 per million Actions tier.
+- The second Namespace with 500 million Actions is billed as follows:
+  - The first 300 million Actions are billed at the $23.25 per million Actions tier.
+  - The remaining 200 million Actions are billed at the $18.80 per million Actions tier.
 
-The following table outlines the tiers for the credits system:
