A 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. You set the time window and what may be changed. Editing locks once fulfillment starts, and every change is logged.

• 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
• Full log of every change, plus optional email notifications
