About the Waitlist Flow ‑ Alert Restocks
Waitlist Flow helps Shopify merchants recover lost sales through automated back-in-stock alerts and restock notifications. When products sell out, customers can join a waitlist with a single click and receive instant notifications when inventory becomes available again from cancellations, refunds, or restocks.
The app automatically sends stock alerts to the next customer in line, complete with a secure checkout link. Merchants can create waitlists for out-of-stock products, manage slots manually with one-click freeing, and even collect interest before store launches on password-protected sites. Perfect for pre-orders, back-in-stock notifications, and handling no-shows, Waitlist Flow captures revenue that would otherwise be lost to stockouts.
