With YITH Multi Vendor you can turn your e-commerce store into a marketplace (a multi-vendor platform) like Amazon or Etsy. Turn your e-commerce store into a marketplace (a multi-vendor platform) and earn commissions on orders generated by your vendors.
If combined with YITH Order Tracking, also vendors will be able to add the tracking details in their own suborders.
Just make sure you install and activate both plugins, then, enable the Order Tracking module from YITH > Multi Vendor > Modules.
Now, you can enable the carriers from YITH > Order & Shipment Tracking > Carriers.
And now your vendors will be able to see a dedicated Order tracking box in the order details, add the tracking details and choose one of the carriers enabled by the admin.
This data will then only be about a specific order bound to the admin and not any other sub-orders bound to vendors.
For more details about how to configure YITH Multi Vendor, please, refer to the official documentation.
This combination is also fully integrated with YITH Frontend Manager, so your vendors will be able to edit the tracking code and carrier also when checking the order details from the frontend.
