 ### Billing and Credits
 
-<Billing/>
+Clusters created with Compatibility Matrix are billed by the minute. Per-minute billing begins when the cluster reaches a `running` status and ends when the cluster is deleted. Compatibility Matrix marks a cluster as `running` when a working kubeconfig for the cluster is accessible.
+
+You are billed only for the time that the cluster is in a `running` status. You are _not_ billed for the time that it takes Compatibility Matrix to create and tear down clusters, including when the cluster is in an `assigned` status.
+
+For more information about pricing, see [Compatibility Matrix Pricing](testing-pricing).
+
+To create clusters with Compatibility Matrix, you must have credits in your Vendor Portal account.
+If you have a contract, you can purchase credits by logging in to the Vendor Portal and going to [**Compatibility Matrix > Buy additional credits**](https://vendor.replicated.com/compatibility-matrix).
+Otherwise, to request credits, log in to the Vendor Portal and go to [**Compatibility Matrix > Request more credits**](https://vendor.replicated.com/compatibility-matrix).
