Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureWhen a customer places an order with a different shipping address, their default address is silently overwritten. This causes problems with local delivery apps, customer segmentation, marketing automations, and any workflow that relies on accurate default addresses. AddressLock fixes this automatically.
Mistyped and incomplete shipping addresses lead to failed deliveries, refunds, and support tickets. ZipSentry checks every address at checkout against rules you choose, such as requiring a house number, blocking P.O. boxes, or validating postal code format. Each rule can block checkout or flag the order for review, so you decide what is worth stopping a sale over.

- Smart detection — only reverses order-triggered, not intentional, updates.
- Flag mode tags risky orders for review
