If you want vendors/listing owners to submit their own products you’ll want to look at the WooCommerce Product Vendors plugin (Plugin sold separately).
The WooCommerce Product Vendor plugin has options to manage, calculate, and pay commissions. You can manage your commissions by going to the Commissions menu item within the WooCommerce Product Vendor plugin. Here you will be able to add new commissions and edit existing ones.
Details regarding paying commissions to your vendors can be found on the WooCommerce Product Vendors documentation area.
