Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCheck new orders after checkout, review flagged addresses, and resolve issues before shipping—without interrupting checkout. AddressSure spots missing unit information, postal mismatches, and your chosen address warnings. Compare the original and suggested address in Shopify admin, then accept a correction or keep the original.
Some carriers (e.g. Fedex) charge extra fees or refuse delivery to PO Boxes. SafeShip validates customer addresses at checkout and blocks orders with PO Box addresses before payment. This prevents failed deliveries, avoids carrier surcharges, and saves you from manually reviewing orders. Customers see a clear message explaining why their address cannot be used, reducing support requests.
