Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureA wrong apartment number or the wrong size turns into a support ticket or a return. Selfix lets customers fix these themselves, minutes after buying. The edit option appears on the order confirmation page and in the customer account. Customers can correct their shipping address, and where enabled, swap a variant for another size or colour, leaving the order total unchanged.
Sell items whose exact weight you only know after packing. Customers pay the listed price at checkout. When you pack the order, enter the actual weight on the order page and Weighwise refunds the difference automatically, or sends a payment link if the item came out heavier. It adjusts the payment instead of editing the order, so it works with shipping, pickup and local delivery.
- Customers correct their own shipping address after checkout
- Set how long edits stay possible, from 15 minutes to 4 hours
- Edits lock automatically as soon as fulfillment begins
- Variant swaps never change the order total and require stock
- Enter actual weights on the order page and see the new price instantly
- Refund the difference automatically when an item weighs less
- Email a payment link, collect in person, or waive when it weighs more
- Works with shipping, in-store pickup and local delivery orders
