By default, Multi-Vendor is tailored for cases when vendors ship their products by themselves, separately from each other. The money for shipping goes to vendors. Vendors determine the shipping cost and the shipping methods.
This approach is easier on marketplaces. Especially those marketplaces that are just starting and can’t handle shipping for all their vendors.
However, some marketplaces work differently. They collect the products from all vendors first, and only then ship the whole order to customers. Some of the marketplaces even have their own vans for delivery. Naturally, the money for shipping should go to the marketplace in this case.
A marketplace may even offer both types of shipping. Some vendors ship on their own, and others rely on the marketplace. To address this, Multi-Vendor has an add-on called “Order fulfillment by marketplace”.
on cs cart multi-vendor why does shipping cost go to vendors income even tho the owner of the shipping comany is the marketplace
the shipping cost money should go to the marketplace owner not the vendors
In standard Multi-Vendor, vendors are responsible for shipping, and therefore receive money for it. A shipping method that belongs to the marketplace is a way to ensure that every vendor offers a shipping method to customers at checkout. That's why in version 4.14.1 you can enable a shipping method that belongs to the marketplace for all new vendors by default.
If the marketplace actually handles shipping for vendors, then that's what the "Order fulfillment by marketplace" add-on is for. It makes the shipping cost money go to the marketplace.
