# Purchase & Activation
## Pricing
Koel Plus employs a super simple pricing model: a __one-time__ payment of {{ config.plus.price }}.
You read that right: no subscription, no recurring payments, no hidden fees, no per- or additional-seat costs — I hate those bullshit as much as you do.
Pay __once__, and you get all current _and_ future updates at no extra fee, forever.

## Activation
After purchasing, you'll receive an email with a license key. To activate Koel Plus, you can use either the web interface or the command line.
### Via the Web Interface
1. Log into your Koel installation as an admin and locate the "Upgrade to Plus" button in the bottom-left corner of the screen.
2. Click the button to bring up the "Koel Plus" dialog:
3. Click "I have a license key," enter your key in the input field, and click "Activate."
4. If the key is valid, Koel will display a Success message and reload itself.
### Via the Command Line
From the root of your Koel installation, run:
```bash
php artisan koel:license:activate YOUR_LICENSE_KEY
```
If the key is valid, you'll see a Success message.
### Verification
To verify that Koel Plus is activated, reload the web app if you haven't done so.
Afterward, trigger the About Koel modal by clicking the icon in the bottom-right corner of the screen.
You should see the information about your Koel Plus license in the modal.
## Deactivation
If for any reason you need to deactivate Koel Plus, you can do so via the command line:
```bash
php artisan koel:license:deactivate
```
Reload Koel, and it will revert to the Community edition. You can re-activate it at any time following the steps above.
