# Services

Services are a way for plugins to extend core functionality. While [components](../plugins-intro.md) let you add visual elements, services let you provide implementations for platform capabilities such as payment processing, receipt printing, and barcode scanning.

## Registering a service

Services are registered inside your plugin using `context.service.addService()`:

```javascript
export default async context => {
    context.service.addService({
        type: 'receiptService',
        // ... service-specific properties
    });
};
```

Each service has a `type` property that identifies the kind of service being registered.

## Available services
