What merchants think

Feedback submitted

Merchants say this app reliably recovers revenue from stockouts and provides clear demand insights by showing which products and variants customers await. They like the simple setup, strong Shopify/theme integration, and automated email/SMS/push alerts with FIFO controls, preorders, and alternative product suggestions. Customization options and support for complex variants are praised. Support is frequently described as fast, proactive, and willing to implement customizations and new features.
