Postal-zone and low-order delivery surcharges

DeliveryCraft lets merchants configure delivery surcharges for postal-code prefixes and low-value orders. Rules are stored in private app data and reviewed from the merchant dashboard. The additional-fees handler reads that configuration during checkout. A subtotal waiver can remove the configured surcharge when an order reaches the merchant's threshold. Distance-radius and delivery-window fees require shopper scheduling or geolocation data that is not part of the current integration. They are excluded from the live fee calculation until that input path is verified. Built with native cloud architecture, all configuration stays within private store collections with zero external servers. Store owners maintain complete control over dispatch costs while keeping the customer checkout experience transparent and seamless.
