# Activate Subscription

> Activate subscriptions and select individual items for activation

After creation, a subscription is in **Draft** status. To start billing, the subscription must be activated.

## Start Activation

Open the subscription and click the **Activate** button in the top action bar.

The activation dialog opens with the following options:

### Activate All Items

By default, the **Activate all items** option is enabled. In this case, all subscription items are activated simultaneously.

<Tip>
  If you only want to activate specific items, disable the **Activate all items** option. An item selector appears where you can choose individual items.
</Tip>

### Select Items

When **Activate all items** is disabled, a product list is displayed. Each item shows the following details:

* **Product name** and description
* **Status badge** (Draft, Active, etc.)
* **Price model** (e.g., Flat-rate, Tiered)
* **Billing start** — the date from which billing begins

<Info>
  If a subscription contains products across multiple phases (different start dates), items are grouped by phase.
</Info>

#### Search and Selection

* Use the **search bar** to filter items by name or description (appears when there are 6 or more items)
* Click **Select all** to select all items at once
* Child products are automatically selected along with their parent

### Adjust Billing Start

By default, billing starts on the contract start date associated with each item.

To override the billing start date manually, enable the **Adjust billing start** option. A date picker appears where you can select the desired start date.

<Tip>
  When you adjust the billing start, the original date is shown with a strikethrough in the product list, and the new date is highlighted. This provides a clear visual indicator of the change being applied.
</Tip>

## Confirm Activation

Click **Activate subscription** to proceed. The subscription transitions to **Active** status and billing begins on the specified date.

<Warning>
  Activation cannot be undone. Make sure the correct items and billing start date are selected before confirming.
</Warning>

## Activate Items Later

If an active subscription contains new items in **Draft** status (e.g., after adding new products), the activation dialog can be opened again to activate those items individually. In this case, the **Activate all items** option is not shown.
