# Cancel or refund a payment

> After making a payment, further actions might be required, such as cancellation, and refund.

After initiating a payment, the Acquiring Service Providers (ACQPs) can cancel or refund a payment.

-   **Cancellation:** The ACQP can proactively cancel a payment when no payment result is received after the payment expires, or when the ACQP closes the payment before receiving the payment result.
-   **Refund:** The ACQP can apply for a refund of successful payments on behalf of its merchants. Both full and partial refunds are supported.

The following table lists more differences between cancellation and refund:

|  | **Time** | **Amount** | **Fee items** | **Settlement** |
| --- | --- | --- | --- | --- |
| **Cancellation** | Before 00:15 UTC+8 of T+1 day | Full amount only | No fees occur for canceled transactions. | Canceled transactions are excluded in the clearing and settlement files. |
| **Refund** | Within one calendar year | Full, partial, and multiple partial refunds | The interchange fee (also known as interpartner fee) is refundable while the service fee is non-refundable. | Refund transactions are included in the clearing and settlement files. |
