When an item sells out, a refund or cancelled order means a lost sale. Badilify adds a third option: a backup. Match sold-out products to in-stock substitutes by rule, let shoppers pick a backup at checkout, or send a branded link to choose a replacement. Recover the sale instead of refunding. Bilingual English + Arabic with full RTL — built for Gulf and global stores. Your data: we read only order number, customer name, and email — to verify orders and send the backup link. Nothing else, ever.
