 ## 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.

+View Datadog costs, usage trends, and projected end-of-month costs in a single page, with daily breakdowns, product-level detail, and multi-organization filtering.
+
+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
+
+- **Product Category**: Filter all views by broader product family, such as  Infrastructure, APM, Logs, Security, or AI/ML.
+- **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.

+
+## Cost summary
+
+At the top of the page, the cost summary shows:
+
+- **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
+
+Below the cost summary, the **Daily Cost Breakdown** stacked bar chart shows costs broken down by billing dimension for each day of the selected period. Each color in the chart represents a different billing dimension. Click the expand icon to view the chart full screen.

+- **Usage** (total units consumed, in natural units — for example, PB of scanned data, custom metrics) (on Total Cost and Usage-related cards)
+
+Click **View Details** on any card to open the [product detail page][2].
+
+{{< 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.
+
+Click anywhere on a product row to open the [product detail page][2]. Hover over the end of a row to quickly create a cost monitor for that billing dimension.
+
+#### Table columns

+| Usage — Total | Total usage in natural units |

+
