How are FBA/WFS transportation 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.

LTL, FTL, storage-and-forward, or other transportation arranged outside an Amazon-partnered workflow must be quoted and approved separately. A portal service selection or tracking entry does not by itself book a carrier.

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