Product Vendors for WooCommerce

The client receives inventory from vendors, and fulfills all orders on behalf of vendors, but still wants to offer a commission.

The client wants to control all vendor inventory and disable the option for vendors to fulfill orders (or any other Dashboard menu item if they later decide to do so).

The client wants to have an option in the plugin to change the Vendor labels and slug.

When the client fulfills an order on behalf of the vendor and sets that order to Completed, it should automatically change the vendor fulfillment status to Fulfilled. Currently, the vendor fulfillment status can only be changed by the vendor, so those statues remain Unfulfilled, even after my client has set the order status to Completed.
