I am facing some problem in choosing a payment gateway that can allow direct transfer from the customer's coming to my website to the merchant's registered on my website. My website acts as a place for merchants to advertise and offer some products which can be bought on my website itself but I do not want to be involved in the payment transfer stuff, so I am looking for a way through which the customer's account can directly be debited and the merchant's account receives the money without any hassles.
