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

DiscountComposer replaces Shopify's standard discount tools with a flexible, visual builder for automatic, codeless discounts. Merchants create percentage, fixed-amount, tiered, and Buy X Get Y discounts, then target them by product, collection, or customer segment. Discounts can be scheduled, limited by order value, and set to combine with other promotions. A cart progress bar shows shoppers how close they are to the next discount tier, encouraging larger orders.

• Create percentage, fixed-amount, tiered, and Buy X Get Y discounts
• Target discounts by product, collection, or customer segment
• Exclude specific products or collections from any discount
• Control whether discounts combine with other active promotions
• Show shoppers a cart progress bar toward the next discount tier
