Auto re-routing commissions

hi all,
i am in the midst of studying an ecommerce proposal for a potential client.

my client strikes a deal with his friend, a toy shop owner - a traditional brick & mortar business & the toy shop have no website or ecommerce site. so my client wants to build an ecommerce site with his own domain and business name (different from his friend’s toy shop) to help his friend (the toy shop owner) to sell his products.

he wanted the commission from the sales from his ecommerce site to re-route to his paypal or bank account based on an agreeable rate set between them two.

for example; my client gets 40% and his toy shop owner friend gets 60% from each sales. so once the customer paid & checkout, the 40% automatically goes to my client’s coffers and 60% goes to his friend’s.

i was wondering if there is any script/addon/module whatever you call it that does that???

thanks for the replies. that concluded that no such thing as rerouting based on ratio exist

Once order is being placed & payment is received, it must go to one account only.
Here it is not possible to directly route payment 40:60 ratio, but once payment is received in any one account then only it is possible to send 40 or 60 percent to other account.

Is it possible to send 40% of the sum to your client using payment system back-end?

It is better to keep customers checkout simple.
