WPCargo Parcel Quotation allows clients to request for shipment quotation by adding shipment information themselves. Administrator reviews and quotes the shipment with the extra charges for approval. An email notification will be sent to the customer with the complete information of shipment including the additional charges. Customers will then have the capability to approve or decline the quoted shipment. You can setup your list of additional fees for extra charges. These charges will be added on Woocommerce checkout as additional fee and will be included in the total amount.
