            courier = CourierService.objects.get(auction=auction, courier_id=courier_id)
            
            if auction.current_bid is not None:
                price = int(round(float(auction.current_bid) * 100.0))

Things need to resolve

• I am creating a platform where user will earn money whenever his referral product is sold The main concept is that when buyer will make the payment this payment should be split into 4 parts

• admin

• seller

• referral

• shipment

for now payment is getting split into admin and seller now i want that if that particular seller has a seller who's referral code he has used to create the account then that referral should receive the 2 percent of amount from the admin amount

and i want that shipment amount should be send the new stripe account(i have created two stripe account 1 for seller admin and referral and one just for amdin) i.e i have two stripe api

please suggest the solution or any modification will will improve this

thanks in advance
