 ## Usage reports
 
 View hourly usage of your account across all billable parameters as well as the top 5000 custom metrics submitted. If your organization is the parent-organization in a [multi-org account][3], you can also view the usage of child-organization accounts by toggling between "Overall" and "Individual Organizations" at the top of the page. Individual child-organization accounts are isolated. They are only able to view their own usage and custom metrics.

+
+The [**Bill Overview** page][1] gives administrators a single view of Datadog costs and usage. It is automatically enabled during the phased rollout starting March 2026.
+
+## Global filters
+
+The following filters apply to the **Bill Overview** page:```
+
+the original isn't bad or wrong, just making this fit with the docs tone a little more
+

+- **Billing Dimension**: Filter to a specific billing dimension.
+- **Sub-Org**: Filter to a specific child organization.
+- **Group by Sub-Org**: Toggle to group costs by sub-organization.

+- **Estimated cost to date**: Total estimated cost for the days elapsed in the current billing period (for example, "Estimated Mar 1–Mar 18 Cost").
+- **Projected total**: Estimated total cost if current usage patterns continue through end of month, with month-over-month percentage change.
+
+## Daily Cost Breakdown
+

+
+{{< img src="account_management/plan_and_usage/bill-overview-trends-light.png" alt="Trends tab showing product cards sorted by Highest Total Cost" >}}
+
+## Product List tab
+
+The **Product List** tab shows all billing dimensions in a table with cost and usage side by side.
+
+#### Additional filter (Product List only)
+
+- **Cost Type**: Filter to show **Committed** costs, **On-Demand** costs, or **All** costs.
+
