Regardless of payment method (i.e. PayPal, Stripe, Klarna), the purchase action is considered a transaction directly between the customer and the store selling the goods. The funds are directly transferred to the stores account at the selected payment provider.
If you have received a payment via PayPal, simply log in to your PayPal account. From there you can transfer the money to your bank account.
If you are using Stripe, you will need to register a valid bank account in your Stripe account, if you wish to receive payments to your bank directly. You can also choose to transfer funds manually. Please note that your first transaction with Stripe will take a little longer to process than the following ones.
If you are using Klarna as a payment option and want your payments transferred directly to your bank account, you will need to first enter your bank account details into your Klarna account, after which you will receive a code to your registered home address. Use this code to confirm that you are the rightful owner of this bank account, and you transactions will thereafter go to you bank account automatically.
