PayPal Parallel Payments
PayPal's Parallel Payments using the Adaptive Payments allows you to automatically collect the sale transaction fee when the buyer pays for a purchase using PayPal.
If the seller did not enable PayPal as a direct payment method, or if the buyer pays through another payment gateway or does not pay through your website, the sale transaction fee will be charged normally.
You can still choose which party is to pay the sale transaction fee, if the buyer is to pay, then if choosing to pay with PayPal, s/he will be notified that the sale transaction fee will be included and the total amount to be paid.
Important: Please check with PayPal first if the Adaptive Payments module is available for your account. More information on the Adaptive Payments module can be found [ here ].
