I am working on a web application for a client and he wants the payflow to work sorta like this:
Seller makes an offer for an item
Customer purchases the item
The seller sees the item is paid for but won't get the payment
When the item has been marked shipped the payment minus app fee and paypal fees will be sent to seller
App Fee is deposited into the application's paypal account
I have implemented it using paypal's express payment api and do the payouts manually. But this has caused double paypal fee's which are incorrect. My client wants to use adaptive payments but that isn't going to work since they require the seller to be the primary receiver and the merchant service be the secondary but for out desired flow that won't work. What other option do I have?
