Back in Stock
Shopify back-in-stock app for restock alerts
Back in Stock by Amp is a Shopify app for capturing and converting demand when products are out of stock. It provides customizable signup forms, pop-ups, and "Notify Me When Available" buttons, followed by restock alerts sent via email, SMS, and web push within 60 seconds. It also supports preorders with full or partial payment options, and demand analytics for inventory planning.
Key features include customizable, brand-matched notification forms and buttons, multi-language support, delivery policy and window customization, and integrations with Klaviyo, Mailchimp, PageFly, Campaign Monitor, Constant Contact, Zapier, and Shopify. Preorder functionality includes full payment, partial deposit, or discount-based incentives. Analytics track notification performance, conversion impact, and demand insights for inventory and marketing planning. The Pro plan adds API access and webhooks.
Back in Stock is designed for Shopify merchants managing out-of-stock products and preorder launches. It offers a free plan with up to 10 notifications per month and unlimited registrations, plus three paid tiers (Starter, Growth, Pro) with increasing notification allowances, all with a 14-day free trial. SMS notifications are billed separately per message based on destination country. Plans are flat-rate with optional notification top-ups rather than automatic usage-based overage fees.
