If you sell goods on Shopee and need to refund customers, you can follow the steps below:

1. In the Shopee merchant backend, go to the "Order Management" page and find the order that needs to be refunded.

2. Click the "Refund" button on the right side of the order to enter the refund application page.

3. On the refund application page, select the reason for the refund and fill in the refund amount and description.

4. After confirming that the refund information is correct, click the "Submit Refund" button and wait for the Shopee platform to review.

5. After the review is passed, the Shopee platform will return the refund amount to your Shopee merchant wallet.

6. You can withdraw the wallet balance to your bank account or Alipay account.

It should be noted that if the balance of your Shopee merchant wallet is not enough for the refund, you need to recharge to a sufficient amount before you can make a refund. At the same time, the refund amount will be returned to your merchant wallet after the platform's review and approval. The specific arrival time may be delayed, so you need to wait patiently.
