About this app
Back In Stock helps Shopify merchants capture demand when products or variants sell out, then notify interested customers as soon as inventory returns. The app adds a notify experience to sold-out product pages through a Shopify theme app embed and optional app block. Shoppers can leave their email address for a specific unavailable variant. The app stores those requests in a merchant dashboard, checks restock events from Shopify, and sends alerts when the variant becomes available again.
