# Adds the ability to clear invoicing rules on Invoice Items

## What’s new

Adds the [invoicing_rules](https://docs.stripe.com/api/invoiceitems/update.md?api-version=2026-09-30.endive#update_invoiceitem-invoicing_rules) parameter to the [update Invoice Item](https://docs.stripe.com/api/invoiceitems/update.md?api-version=2026-09-30.endive) method. You can pass an empty string to this parameter to remove all previously defined invoicing rules from a pending Invoice Item, making it immediately eligible for invoicing. Setting `invoicing_rules` to any non-empty value isn’t supported.

Invoicing rules are used to [defer subscription credit prorations](https://docs.stripe.com/billing/subscriptions/credit-proration-deferral.md). The [invoicing_rules](https://docs.stripe.com/api/invoiceitems/object.md?api-version=2026-09-30.endive#invoiceitem_object-invoicing_rules) property on the [Invoice Item](https://docs.stripe.com/api/invoiceitems/object.md?api-version=2026-09-30.endive) object contains the rules that control when an Invoice Item is eligible for invoicing. After you clear the rules, the property returns an empty array.

## Impact

If your integration creates Invoice Items that have invoicing rules applied (for example, credit proration items with a `defer_until_credited_items_resolved` rule), you can remove those rules by passing `invoicing_rules=""` in an [update Invoice Item](https://docs.stripe.com/api/invoiceitems/update.md?api-version=2026-09-30.endive) request. You can only clear rules on Invoice Items that are not yet attached to an invoice—attempting to clear rules on an attached item returns a `400` error.
