+title: About the google_billing_project_billing_info resource
+platform: gcp
+---
+
+## Syntax
+A `google_billing_project_billing_info` is used to test a Google ProjectBillingInfo resource
+
+## Examples
+```
+describe google_billing_project_billing_info(project_id: 'chef-gcp-inspec') do
+  it { should exist }
+
+  its('billing_account_name') { should eq 'billingAccounts/012345-567890-ABCDEF'}
+  its('billing_enabled') { should eq true }
+end
+```
+
+## Properties
+Properties that can be accessed from the `google_billing_project_billing_info` resource:
+
+
+  * `project_id`: The project id to retrieve billing info for.
+
+  * `billing_account_name`: The resource name of the billing account associated with the project, if any. For example, `billingAccounts/012345-567890-ABCDEF`.
+
+  * `billing_enabled`: True if the project is associated with an open billing account, to which usage on the project is charged. False if the project is associated with a closed billing account, or no billing account at all, and therefore cannot use paid services.
