Ask HN: Payment handler for "directory" type site (multiple recipients)

Hi,

I'm toying with an idea which involves your standard "directory" type commerce site where you aggregate sellers (e.g. different restaurants) and let them receive their own payments off of the "food" they'd sell on the site. (I know this has been done to death, it's just for illustrative purposes). Is there any service that lets you implement this kind of payments system (i.e. let new sellers register and receive payments straight to their account) or would I have to handle the payments centrally and redistribute to end recipients myself? Any heads up much appreciated. Thanks.
