# Adds the ability to itemize proration discount amounts ## What’s new Adds the ability to itemize proration discount amounts, so proration amounts and discount amounts are displayed consistently with non-prorations. When enabled, the proration [amount](https://docs.stripe.com/api/invoice-line-item/object.md?api-version=2025-09-30.clover#invoice_line_item_object-amount) properties show gross amounts before discounts are applied, and [discount amounts](https://docs.stripe.com/api/invoice-line-item/object.md?api-version=2025-09-30.clover#invoice_line_item_object-discount_amounts) include the actual applied discount amounts. When disabled, the proration discount properties include discount IDs, but discount amounts are 0. ## Impact You can now itemize proration discount amounts by setting the [proration_discounts](https://docs.stripe.com/api/subscriptions/create.md?api-version=2025-09-30.clover#create_subscription-billing_mode-flexible-proration_discounts) parameter to `itemized` when creating subscriptions, subscription schedules, quotes, checkout sessions, or preview invoices. You can also set this parameter to `itemized` for an existing subscription by [migrating](https://docs.stripe.com/api/subscriptions/migrate.md?api-version=2025-09-30.clover#migrate_subscription-billing_mode-flexible-proration_discounts) it. However, you can’t migrate a subscription from `itemized` to `included`. ### Changes summary | Object | Property | Included | Itemized (new behavior) | | ----------------------- | ---------------------------------- | ------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------ | | **Proration Line Item** | `amount` | Net amount (after discounts) | Gross amount (before discounts) | | | `discount_amounts` | Missing item-level discounts; group-level discounts show `amount=0` | All discounts included with accurate amounts | | **Invoice Item** | `amount` | Net amount | Gross amount | | | `net_amount` (new property) | Net amount for non-discountable invoice items; otherwise null | Net amount for non-discountable invoice items; otherwise null | | | `proration_details` (new property) | All discounts included with `amount=0` | All discounts included with accurate amounts | | **Invoice** | `total_discount_amounts` | Excludes proration discounts | Includes proration discounts | | | `subtotal` | Includes net proration amounts (discounts already applied) | Includes proration amounts after item-level discounts (group-level discounts applied separately) | ### Example 10 USD gross debit proration with 10% item-level discount and 2 USD group-level discount **Included:** The following example shows the existing behavior, with discounts already applied: Response: ```json // Line Item { "proration": true, "amount": 700, // Net: 7 USD after discounts (10 USD - 1 USD item - 2 USD group) "discount_amounts": [ // Item-level discount missing entirely {"amount": 0, "discount": "di_group_2off"} // Group-level shows ID but no amount ] } // Invoice Item { "proration": true, "amount": 700 // Net amount only } // Invoice { "total_discount_amounts": [ {"amount": 0, "discount": "di_group_2off"} // Missing item-level proration discount ], "subtotal": 700 // Adds proration amount after all discounts } ``` **Itemized:** Request: ```json // POST /v1/subscriptions { // ... omitting irrelevant fields ... billing_mode: { type: "flexible", flexible: { // New parameter: only available when billing mode type is flexible proration_discounts: "itemized" // Default value is "included" } } // ... omitting irrelevant fields ... } ``` Response: ```json // Line Item { "proration": true, "amount": 1000, // Gross: 10 USD before discounts "discount_amounts": [ {"amount": 100, "discount": "di_item_10pct"}, // Item-level discount now visible {"amount": 200, "discount": "di_group_2off"} // Group-level with actual amount ] } // Invoice Item { "proration": true, "amount": 1000, // Gross amount "net_amount": 700, // New property: net amount after both discounts "proration_details": { // New property: populated when the invoice item is a proration "discount_amounts": [ {"amount": 100, "discount": "di_item_10pct"}, {"amount": 200, "discount": "di_group_2off"} ] } } // Invoice { "total_discount_amounts": [ {"amount": 100, "discount": "di_item_10pct"}, // Now includes item-level proration discount {"amount": 200, "discount": "di_group_2off"} // Now includes group-level proration discount ], "subtotal": 900 // Includes proration amount after item-level discounts } ``` ### Upgrade considerations - **Scope**: This functionality is only available on subscriptions with flexible billing mode. - **One-way migration**: After you enable itemized discount amounts for a subscription, you can’t revert to included. - **Code changes required**: If your integration reads proration [amount](https://docs.stripe.com/api/invoiceitems/object.md?api-version=2025-09-30.clover#invoiceitem_object-amount) properties expecting net values, update to use the new [net_amount](https://docs.stripe.com/api/invoiceitems/object.md?api-version=2025-09-30.clover#invoiceitem_object-net_amount) property instead. - **Historical invoices**: Existing invoices reflect the behavior that was active when you created them. - **Mixed invoice support**: Single invoices can contain both included and itemized proration line items if you migrate a subscription between creating prorations. ## Changes #### REST API | Parameters | Change | Resources or endpoints | | --------------------------------- | ------ |
