Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureExpress wallets — Shop Pay, PayPal, Apple Pay, Google Pay — skip your address form, so orders arrive with a street but no house number, or no postal code at all, and the delivery fails. A missing house number only produces a warning at checkout, which the buyer can ignore. This app turns it into a block: checkout cannot be completed until the address is fixed, wallets included.
For some destination countries, missing shipping phone numbers can lead to delivery delays, failed delivery attempts, and extra support work for merchants. ZonePhoneGate helps prevent this by requiring a shipping phone number only for the destination countries you select. Customize the checkout message and block checkout until the phone number is added.
