# Account and billing Most of what the account page on the website does, the client does too. | Command | Does | |---|---| | `machine account show` | shows your account | | `machine account credits` | shows your usage credits | | `machine account activity` | lists what they were spent on | | `machine account products list` | lists what is for sale | | `machine account buy usage` | opens checkout for a pack of usage credits, sized in euros as listed by `products` | | `machine account buy plan` | subscribes to a plan, or switches tier if you already have a paid one | | `machine account upgrade`, `downgrade` | moves you to a higher or lower plan | | `machine account cancel` | cancels the subscription: the plan stays until it renews, then drops to Free, and your usage credits stay | | `machine account invoices` | lists your invoices | | `machine account orders` | lists your purchases, and resumes or cancels a pending checkout | | `machine account payment` | updates your payment method | | `machine account portal` | opens your billing settings | | `machine account api-keys` | creates, lists, deletes and sets the expiry of API keys | | `machine account devices` | lists where you are signed in (`--revoke` signs one out) | | `machine account email` | changes your email address | | `machine account close` | closes the account, in two steps (`--cancel` stops it) | `payment`, `portal` and `cancel` open a browser. Add `--link` to print the address instead. How credits are granted and used is in the [usage credit terms](/machine/legal/usage-credit/). Runs, logs and disks take up space in your account. `machine storage show` says how much, and `machine storage prune` frees the space that deleted runs and disks left behind. `machine storage prune --status` shows the current or last prune.
