A product without a compatible selling plan can't be added to a subscription. - The subscription has an `Active` status. You can't add products to subscriptions with a `Failed`, `Paused`, or `Cancelled` status without first resolving or reactivating them. ## How can I add a product to a subscription in the Skio Dashboard? 1. In your Skio Dashboard, go to **Subscribers** > **Subscriptions**. 2. Search for the customer by name, email, or subscription ID, then click the subscription you want to update. 3. On the subscription detail page, click **Manage products**. 4. From here you can add a recurring subscription product or a [one time upsell](/help/docs/1-time-upsells). Select the appropriate option, search for the product by name or SKU, choose the correct variant, and confirm the quantity. 5. Click **Save** to apply the changes. The product will be included in the subscriber's next scheduled order. ![](https://cdn.us.document360.io/a953bba6-c70d-43ce-bc77-d7f32a8fc514/Images/Documentation/CleanShot 2026-03-10 at 09.58.30.gif?sv=2026-02-06&spr=https&st=2026-10-13T22%3A10%3A47Z&se=2026-10-13T23%3A10%3A47Z&sr=c&sp=r&sig=8bzR5EqwdnZh0HZOsI%2BR3uN3O0MLKLUW3%2FoijeE6HQE%3D) ## What needs to be configured to allow product additions in the Customer Portal?

Go to **Products > Selling Plans** in your Skio Dashboard and confirm the product is assigned to a compatible selling plan. ### Product unavailable > [!NOTE] > Be sure to check the specific product has [**Show in edit products page for customers**](/help/docs/adding-products#customer-portal-visibility) enabled in **Products > Products** The product variant may be out of stock and your inventory policy does not allow it to be purchased, or the product is currently set to **Draft** or **Archived** in Shopify. Check the product's availability in your **Shopify admin**, and update your inventory policy in your Skio dashboard under **Settings > Billing & Orders** if needed. ### Cannot modify subscription in current state The subscription is not in an **Active** state. If the subscription is: - **Failed**, the [payment method may need to be updated](/help/docs/updating-and-adding-credit-cards-in-the-customer-portal-1) before changes can be made. - **Paused**, it must be resumed first. - **Cancelled**, a new subscription will need to be created or the cancelled subscription needs to be reactivated. ### Option doesn't appear in the dashboard If you don't see the **Add product** button on the subscription detail page, confirm that you have the correct **user permissions** for subscription management. Account owners can review and update user roles under **Account > Users**.
