The payment made by the buyer will first go to the Shopee Guarantee account. Once the buyer has confirmed that he has received the item or the Guarantee period has ended, the payment will be released to your bank account.
Make sure that you have set up your Bank Account on the App for Shopee to be able to transfer your payment:
1) Go to Me> My Income > My Bank Account
2) Verify password
3) Fill in your bank account information. Make sure your bank account accepts check deposits.
