You can't transfer between Stripe accounts. Charges going through Connect have the same fees as ones not going through connect (namely, 2.9% and $0.30).
If you're using our application_fee parameter to take your own fee out of a transaction, you get the full amount you request. Both that full amount, and the Stripe fee for the charge, are subtracted from the total amount paid to the seller.
To illustrate, a $100 charge with a $1 application fee would end up sending $1 to the application, $3.20 to Stripe, and $95.80 to the seller.
This is a huge problem for me. My marketplace was designed to take commissions out of each sale so our application fee is $0. I have to charge the customers who buy the products the full amount, and then a percentage of the sale is disbursed to the seller and our site (the application).
If there are multiple parties involved in referring the sale, I will be charged not one but a multiple of the Stripe fees whenever money is disbursed to appropriate parties involved in one single sale.
Furthermore, because I have to process returns I will not be able to send the payment directly to the seller immediately. The payment would be retained in my account after a period of time before I could transfer it to the sellers.
