+Got a project you no longer need and don't want to be charged for? Simply delete it.

+To stop being charged for a project:
+1. Log in to the [((ess-console-name))](((ess-console))).
+
+2. Find your project on the home page in the **Serverless Projects** card and select **Manage** to access it directly. Or, select **Serverless Projects** to go to the projects page to view all of your projects.
+
+3. Select **Actions**, then select **Delete project** and confirm the deletion.
