By default, shipping methods and fees are collected by the Retailer according to their store's shipping profiles but are not transferred to the Supplier.
As a Supplier, if you need to collect the cost of shipping on Carro orders, there are 3 options:
1. Factor in the shipping fees when considering your revenue splits.
2. Activate Flat Rate Shipping: Suppliers can set shipping fees and free shipping thresholds for items they sell (must be approved by partner).
3. Edit your Carro price(s) to factor the cost of shipping.
