Directing payments to different Merchants

[Bayo]

I'm working on an e-commerce platform which like amazon will contain not only my goods but stuff from other people. Is there a way to route payments based on the goods to their accounts directly ?, so I don't have to collect their money and then send it to them at the end of each month.
And is there a way to automatically send notifications to each dealer based on the goods in the cars because some people will order different products with different dealers and the norm is for me as the owner to get an e-mail showing the total orders (if this happens, I'll have to go through every order and then split them to each dealer myself).
Thanks.
