Hi @ltoso, thanks for getting in touch with us.
The default flow of WC Marketplace only handles the payment from admin to the vendor. Now the admin of the site will get full payment of the order because the customer uses the payment mode enabled via WooCommerce >> Settings >> Payment. (see this scrrenshot – https://prnt.sc/lxbdew)
Now as per WCMp Schedule and payment mode (see this screenshot – https://prnt.sc/m7tciu), the vendor will get their part of the commission.
However, if you want you can pay the vendor directly when the customer pays for the order. To achieve this, you may use WCMp Stripe Marketplace or WCMp Mangopay.
Hence, admin and vendor will get their part of the money instantly from the checkout page.
