# Advanced version

The Advanced version of the Stock Reminder plugin is purchased via an In-App Purchase in the Shopware Store. It removes the limitations of the free version and unlocks additional features.

## Free Version

The free version includes all core features of the plugin:

* Notification form on product detail pages and product listings
* Double opt-in process
* Email delivery via the Flow Builder
* Automatic sending when products are back in stock
* Per-sales-channel configuration
* Dynamic product groups for display and notification conditions
* Subscription management in the administration area
* Automatic cleanup of old entries
* Store API for headless projects

**Limitation:** A maximum of 10 active subscriptions at a time. Once the limit is reached, the notification form is hidden in the storefront and new subscriptions via the Store API are rejected.

## Advanced Version

With the Advanced version you additionally get:

* **Unlimited subscriptions** – No restriction to 10 active entries.
* **Statistics** – Full access to the Statistics tab in the management dashboard with key metrics and trends over time.

## How to Upgrade

You can upgrade to the Advanced version directly from the administration area. In the Subscriptions tab or the Statistics tab, you will find an "Upgrade now" button that takes you to the In-App Purchase.

After purchase, all limitations are removed immediately.
