Hi,
In HikaMarket you have a setting called "shipping per vendor".
It will simulate dynamically warehouses in HikaShop for the different vendors in the cart and you can affect specific shipping method to a vendor.
By activating the "Configuration of plugins by vendors", you give the authorization of the vendor to create and manage their own shipping methods in the front-end. So one vendor can create a "UPS" or "Fedex" shipping plugin with his own credentials, his own location, etc.

About the taxes ; they are all processed from one single entity : your store.
There is no integration between the "taxcloud" plugin and HIkaMarket ; so that's not possible to process taxes depending the vendor location (using the vendor tax cloud plugin).
But it could be possible to improve the taxcloud plugin in order to perform such kind of processing ; but it will require that each vendor indicate their tax cloud credentials otherwise the plugin will use the store one.
Otherwise, I know that PolishedGeek developed an "Avalara" plugin and their plugin is fully compatible with HikaMarket.
