How are shipping costs calculated and billed?

FBA and WFS transportation is separate from PrepFort's per-unit prep fee. The final cost depends on carton or pallet count, weight, dimensions, destination fulfillment center, carrier, and service level.

When you use an Amazon-partnered carrier, Amazon calculates the rate and generally charges it through Seller Central. Make sure the shipment plan uses PrepFort's current ship-from address so Amazon can quote the correct route. PrepFort can help create the shipment plan, but Amazon controls its partnered-carrier rates.

For DTC and FBM fulfillment, orders are managed in Packiyo. Shipping is billed at the carrier cost for the service selected. Available services can include USPS, UPS, FedEx, Better Trucks, Amazon Shipping, DHL, and international options; availability depends on the parcel and destination.

Your signed quote and warehousing agreement control any account-specific billing terms.
