+## Credits
 
-Site administrators can view their own [Deep Search](/deep-search) usage for the current quota period directly in the Enterprise Portal. This provides visibility into consumption relative to usage limits.
+Subscription admins can view credit balances and rates for metered services, including [Deep Search](/deep-search) and [Agentic Batch Changes](/agentic-batch-changes), on the **Credits** page. This replaces the former Deep Search usage monitoring page and shows subscription-wide consumption, not an individual user's usage.
 
-To access usage information, you must first [access the Enterprise Portal](#accessing-sourcegraph-enterprise-portal) as a subscription admin.
+1. [Sign in to Enterprise Portal](#accessing-sourcegraph-enterprise-portal) as a subscription admin.
+2. Select your subscription.
+3. Select **Credits** in the subscription navigation.

+### Credit balances
 
+A **credit bucket** is a pool of credits with its own allocation and validity period. Under **Active credit buckets**, the summary shows:
+
+- **Allocated**: Total credits allocated across currently active buckets.
+- **Consumed**: Credits used from those buckets.
+- **Remaining**: Unused credits summed across those buckets. Consumption beyond a bucket's allocation is shown separately as **over allocated**, rather than subtracted from another bucket's remaining credits.
+
+Expired buckets and buckets whose start date is in the future are excluded. These figures describe active allocations, not all-time usage or usage during a selectable date range.
+
+The table lists each active bucket's **Name**, **Credits** consumed out of its total, **Start** date, and **Expires** date. Buckets that have used their allocation are marked **Depleted**. Dates are displayed in UTC. If there are no active buckets, the page displays **No active credit buckets**.
+
+If your subscription has an uncapped overage bucket, its row shows consumption out of **∞**. These buckets are excluded from the numeric summary totals; **Allocated** displays **+ unlimited bucket** to indicate their presence.
+
+### Credit rates and purchasing
+
+The **Credit rates** table lists metered services and their **Credits per unit**. Check this table for current rates, Beta status, general availability dates, and any promotional notes. For the policy on when features begin consuming credits, see [credits and billing](/beta-and-experimental#credits-and-billing).
+
+To purchase additional credits, contact [Sourcegraph support](mailto:support@sourcegraph.com). Enterprise Portal does not offer self-service credit purchases.
+
+### Detailed usage and limits
+
+For a more detailed credit usage breakdown, follow the **Sourcegraph Analytics** link on the Credits page when available. See [Sourcegraph Analytics](/analytics#enablement-instructions) for access requirements.
+
+Credit balances are separate from administrator-configured usage limits. To control Deep Search usage, configure [entitlements](/admin/entitlements) or [role-based access control](/admin/access-control) on your Sourcegraph instance.
