| <a id="proration"></a> `proration` | <code>null | <a href="billing-proration-discount.mdx">BillingProrationDiscount</a></code>  | The prorated discount for the part of the billing period that has already passed when adding a seat mid-cycle. Unlike the proration credit (which refunds the unused remainder of a plan you already paid for), this discount means you are not charged for the portion of the new seat's cycle that has already elapsed. |
| <a id="total"></a> `total`         | [BillingMoneyAmount](https://clerk.com/docs/react/reference/types/billing-money-amount.md) | The total of all discounts applied to the checkout.                                                                                                                                                                                                                                                                       |
