Distribution of payment from a multi-basket, how to implement?

Question

Online shopping

Hello.
It is planned to write a trading platform from 0 and there was a question about the implementation of multi-basket payment.
There will be different sellers on the site (each has its own IP and current account)
Buyers can order goods from different sites and place them in a multi-basket, then pay online.
How to implement a multi-basket payment so that payment is immediately distributed to sellers' settlement accounts, and the buyer pays only once.
What is the point, if the payment is credited to the platform's settlement account and then distributed among the sellers, then all taxes are borne by the trading platform, so it is necessary to implement the payment so that the funds are distributed to each seller depending on the amount of the order.
That is, the payment scheme was as follows:
Multicart > Payment > Seller's checking account 1 > Seller's checking account 2 > Seller's checking account 3
and not this:
Multicart > Payment > Platform's checking account > Seller's checking account 1 > Seller's checking account 2 > Seller's checking account 3

Answer 1

The buyer in your scheme will have to carry out as many transactions as the sellers with all the ensuing goodies in the form of entering a card number, confirming SMS, etc...

Answer 2

Have you found a solution to this issue? or the output is only to carry out as many transactions as there are sellers?
